Detailed Description

+

Abstract class to be used by Host implementations.

+

When implementing EVMC Host, you can directly inherit from the evmc::Host class. This way your implementation will be simpler by avoiding manual handling of the evmc_host_context and the evmc_host_interface.

+
+ + + + + +
+ + + + + + + + +
evmc_access_status evmc::MockedHost::access_account (const address & addr)
+ 		+inlineoverridevirtualnoexcept
+
+ +

Record an account access.

+

This method is required by EIP-2929 introduced in EVMC_BERLIN. It will record the account access in MockedHost::recorded_account_accesses and return previous access status. This methods returns EVMC_ACCESS_WARM for known addresses of precompiles. The EIP-2929 specifies that evmc_message::sender and evmc_message::recipient are always EVMC_ACCESS_WARM. Therefore, you should init the MockedHost with: 

mocked_host.access_account(msg.sender);
+mocked_host.access_account(msg.recipient);
+

The same way you can mock transaction access list (EIP-2930) for account addresses.

+
Parameters
+ + +
addrThe address of the accessed account.
+
+
+
Returns
The EVMC_ACCESS_WARM if the account has been accessed before, the EVMC_ACCESS_COLD otherwise.
+ +

const bytes32 & key 
)
+ 		+inlineoverridevirtualnoexcept
+
+ +

Access the account's storage value at the given key.

+

This method is required by EIP-2929 introduced in EVMC_BERLIN. In records that the given account's storage key has been access and returns the previous access status. To mock storage access list (EIP-2930), you can pre-init account's storage values with the EVMC_ACCESS_WARM flag: 

mocked_host.accounts[msg.recipient].storage[key] = {value,
+EVMC_ACCESS_WARM};
+
Parameters
+ + + +
addrThe account address.
keyThe account's storage key.
+
+
+
Returns
The EVMC_ACCESS_WARM if the storage key has been accessed before, the EVMC_ACCESS_COLD otherwise.
+ +

◆ create_address

+ +
+
+ + + + +
evmc_address evmc_result::create_address
+
+ +

The address of the possibly created contract.

+

The create address may be provided even though the contract creation has failed (evmc_result::status_code is not EVMC_SUCCESS). This is useful in situations when the address is observable, e.g. access to it remains warm. In all other cases the address MUST be null bytes.

+ +

Definition at line 486 of file evmc.h.

+ +
+
+ +

◆ gas_left

+ +
+
+ + + + +
int64_t evmc_result::gas_left
+
+ +

The amount of gas left after the execution.

+

If evmc_result::status_code is neither EVMC_SUCCESS nor EVMC_REVERT the value MUST be 0.

+ +

Definition at line 426 of file evmc.h.

+ +
+
+ +

◆ gas_refund

+ +
+
+ + + + +
int64_t evmc_result::gas_refund
+
+ +

The refunded gas accumulated from this execution and its sub-calls.

+

The transaction gas refund limit is not applied. If evmc_result::status_code is other than EVMC_SUCCESS the value MUST be 0.

+ +

Definition at line 434 of file evmc.h.

+ +
+
+ +

◆ output_data

+ +
+
+ + + + +
const uint8_t* evmc_result::output_data
+
+ +

The reference to output data.

+

The output contains data coming from RETURN opcode (iff evmc_result::code field is EVMC_SUCCESS) or from REVERT opcode.

+

The memory containing the output data is owned by EVM and has to be freed with evmc_result::release().

+

This pointer MAY be NULL. If evmc_result::output_size is 0 this pointer MUST NOT be dereferenced.

+ +

Definition at line 448 of file evmc.h.

+ +
+
+ +

◆ output_size

+ +
+
+ + + + +
size_t evmc_result::output_size
+
+ +

The size of the output data.

+

If evmc_result::output_data is NULL this MUST be 0.

+ +

Definition at line 455 of file evmc.h.

+ +
+
+ +

◆ status_code

Detailed Description

+

EVMC: Ethereum Client-VM Connector API.

+
Copyright
Copyright 2016 The EVMC Authors. Licensed under the Apache License, Version 2.0.
+

+Terms

+
    +
  1. VM – An Ethereum Virtual Machine instance/implementation.
    2. +
  2. Host – An entity controlling the VM. The Host requests code execution and responses to VM queries by callback functions. This usually represents an Ethereum Client.
    3. +
+

+Responsibilities

+

+VM

+
    +
  • Executes the code (obviously).
    • +
  • Calculates the running gas cost and manages the gas counter except the refund counter.
    • +
  • Controls the call depth, including the exceptional termination of execution in case the maximum depth is reached.
    • +
+

+Host

+
    +
  • Provides access to State.
    • +
  • Creates new accounts (with code being a result of VM execution).
    • +
  • Handles refunds entirely.
    • +
  • Manages the set of precompiled contracts and handles execution of messages coming to them.
    • +

Detailed Description

+

Example implementation of the EVMC VM interface.

+

This VM implements a subset of EVM instructions in simplistic, incorrect and unsafe way:

    +
  • memory bounds are not checked,
    • +
  • stack bounds are not checked,
    • +
  • most of the operations are done with 32-bit precision (instead of EVM 256-bit precision). Yet, it is capable of coping with some example EVM bytecode inputs, which is very useful in integration testing. The implementation is done in simple C++ for readability and uses pure C API and some C helpers.

+

+Terms

+
    +
  1. VM – An Ethereum Virtual Machine instance/implementation.
    2. +
  2. Host – An entity controlling the VM. The Host requests code execution and responses to VM queries by callback functions. This usually represents an Ethereum Client.
    3. +
+

+Responsibilities

+

+VM

+
    +
  • Executes the code (obviously).
    • +
  • Calculates the running gas cost and manages the gas counter except the refund counter.
    • +
  • Controls the call depth, including the exceptional termination of execution in case the maximum depth is reached.
    • +
+

+Host

+
    +
  • Provides access to State.
    • +
  • Creates new accounts (with code being a result of VM execution).
    • +
  • Handles refunds entirely.
    • +
  • Manages the set of precompiled contracts and handles execution of messages coming to them.

◆ evmc_status_code

+ +
+
+ + + + +
enum evmc_status_code
+
+ +

The execution status code.

+

Successful execution is represented by EVMC_SUCCESS having value 0.

+

Positive values represent failures defined by VM specifications with generic EVMC_FAILURE code of value 1.

+

Status codes with negative values represent VM internal errors not provided by EVM specifications. These errors MUST not be passed back to the caller. They MAY be handled by the Client in predefined manner (see e.g. EVMC_REJECTED), otherwise internal errors are not recoverable. The generic representant of errors is EVMC_INTERNAL_ERROR but an EVM implementation MAY return negative status codes that are not defined in the EVMC documentation.

+
Note
In case new status codes are needed, please create an issue or pull request in the EVMC repository (https://github.com/ethereum/evmc).
+ + + + + + + + + + + + + + + + + + + + + + +
Enumerator
EVMC_SUCCESS 

Execution finished with success.

+
EVMC_FAILURE 

Generic execution failure.

+
EVMC_REVERT 

Execution terminated with REVERT opcode.

+

In this case the amount of gas left MAY be non-zero and additional output data MAY be provided in evmc_result.

+
EVMC_OUT_OF_GAS 

The execution has run out of gas.

+
EVMC_INVALID_INSTRUCTION 

The designated INVALID instruction has been hit during execution.

+

The EIP-141 (https://github.com/ethereum/EIPs/blob/master/EIPS/eip-141.md) defines the instruction 0xfe as INVALID instruction to indicate execution abortion coming from high-level languages. This status code is reported in case this INVALID instruction has been encountered.

+
EVMC_UNDEFINED_INSTRUCTION 

An undefined instruction has been encountered.

+
EVMC_STACK_OVERFLOW 

The execution has attempted to put more items on the EVM stack than the specified limit.

+
EVMC_STACK_UNDERFLOW 

Execution of an opcode has required more items on the EVM stack.

+
EVMC_BAD_JUMP_DESTINATION 

Execution has violated the jump destination restrictions.

+
EVMC_INVALID_MEMORY_ACCESS 

Tried to read outside memory bounds.

+

An example is RETURNDATACOPY reading past the available buffer.

+
EVMC_CALL_DEPTH_EXCEEDED 

Call depth has exceeded the limit (if any)

+
EVMC_STATIC_MODE_VIOLATION 

Tried to execute an operation which is restricted in static mode.

+
EVMC_PRECOMPILE_FAILURE 

A call to a precompiled or system contract has ended with a failure.

+

An example: elliptic curve functions handed invalid EC points.

+
EVMC_CONTRACT_VALIDATION_FAILURE 

Contract validation has failed (e.g.

+

due to EVM 1.5 jump validity, Casper's purity checker or ewasm contract rules).

+
EVMC_ARGUMENT_OUT_OF_RANGE 

An argument to a state accessing method has a value outside of the accepted range of values.

+
EVMC_WASM_UNREACHABLE_INSTRUCTION 

A WebAssembly unreachable instruction has been hit during execution.

+
EVMC_WASM_TRAP 

A WebAssembly trap has been hit during execution.

+

This can be for many reasons, including division by zero, validation errors, etc.

+
EVMC_INSUFFICIENT_BALANCE 

The caller does not have enough funds for value transfer.

+
EVMC_INTERNAL_ERROR 

EVM implementation generic internal error.

+
EVMC_REJECTED 

The execution of the given code and/or message has been rejected by the EVM implementation.

+

This error SHOULD be used to signal that the EVM is not able to or willing to execute the given code type or message. If an EVM returns the EVMC_REJECTED status code, the Client MAY try to execute it in other EVM implementation. For example, the Client tries running a code in the EVM 1.5. If the code is not supported there, the execution falls back to the EVM 1.0.

+
EVMC_OUT_OF_MEMORY 

The VM failed to allocate the amount of memory needed for execution.

◆ evmc_storage_status

+ +
+
+ + + + +
enum evmc_storage_status
+
+ +

The effect of an attempt to modify a contract storage item.

+

See EVM Storage Change Status for additional information about design of this enum and analysis of the specification.

+

For the purpose of explaining the meaning of each element, the following notation is used:

    +
  • 0 is zero value,
    • +
  • X != 0 (X is any value other than 0),
    • +
  • Y != 0, Y != X, (Y is any value other than X and 0),
    • +
  • Z != 0, Z != X, Z != X (Z is any value other than Y and X and 0),
    • +
  • the "o -> c -> v" triple describes the change status in the context of:
      +
    • o: original value (cold value before a transaction started),
      • +
    • c: current storage value,
      • +
    • v: new storage value to be set.
      • +
    +
    • +
+

The order of elements follows EIPs introducing net storage gas costs:

+ + + + + + + + + + +
Enumerator
EVMC_STORAGE_ASSIGNED 

The new/same value is assigned to the storage item without affecting the cost structure.

+

The storage value item is either:

    +
  • left unchanged (c == v) or
    • +
  • the dirty value (o != c) is modified again (c != v). This is the group of cases related to minimal gas cost of only accessing warm storage. 0|X -> 0 -> 0 (current value unchanged) 0|X|Y -> Y -> Y (current value unchanged) 0|X -> Y -> Z (modified previously added/modified value)
    • +
+

This is "catch all remaining" status. I.e. if all other statuses are correctly matched this status should be assigned to all remaining cases.

+
EVMC_STORAGE_ADDED 

A new storage item is added by changing the current clean zero to a nonzero value.

+

0 -> 0 -> Z

+
EVMC_STORAGE_DELETED 

A storage item is deleted by changing the current clean nonzero to the zero value.

+

X -> X -> 0

+
EVMC_STORAGE_MODIFIED 

A storage item is modified by changing the current clean nonzero to other nonzero value.

+

X -> X -> Z

+
EVMC_STORAGE_DELETED_ADDED 

A storage item is added by changing the current dirty zero to a nonzero value other than the original value.

+

X -> 0 -> Z

+
EVMC_STORAGE_MODIFIED_DELETED 

A storage item is deleted by changing the current dirty nonzero to the zero value and the original value is not zero.

+

X -> Y -> 0

+
EVMC_STORAGE_DELETED_RESTORED 

A storage item is added by changing the current dirty zero to the original value.

+

X -> 0 -> X

+
EVMC_STORAGE_ADDED_DELETED 

A storage item is deleted by changing the current dirty nonzero to the original zero value.

+

0 -> Y -> 0

+
EVMC_STORAGE_MODIFIED_RESTORED 

A storage item is modified by changing the current dirty nonzero to the original nonzero value other than the current value.

+

X -> Y -> X

Function Documentation

+ +

◆ evmc_create_example_vm()

+ +
+
+ + + + + + + + +
struct evmc_vm * evmc_create_example_vm (void )
+
+ +

Example of a function creating an instance of an example EVM implementation.

+

Each EVM implementation MUST provide a function returning an EVM instance. The function SHOULD be named evmc_create_<vm-name>(void). If the VM name contains hyphens replaces them with underscores in the function names.

+
Binaries naming convention
For VMs distributed as shared libraries, the name of the library SHOULD match the VM name. The conventional library filename prefixes and extensions SHOULD be ignored by the Client. For example, the shared library with the "beta-interpreter" implementation may be named libbeta-interpreter.so.
+
Returns
The VM instance or NULL indicating instance creation failure.

Function Documentation

+ +

◆ evmc_last_error_msg()

+ +
+
+ + + + + + + + +
const char * evmc_last_error_msg (void )
+
+ +

Returns the human-readable message describing the most recent error that occurred in EVMC loading since the last call to this function.

+

In case any loading function returned EVMC_LOADER_SUCCESS this function always returns NULL. In case of error code other than success returned, this function MAY return the error message. Calling this function "consumes" the error message and the function will return NULL from subsequent invocations. This function is not thread-safe.

+
Returns
Error message or NULL if no additional information is available. The returned pointer MUST NOT be freed by the caller.
+ +
+
+ +

◆ evmc_load()

+ +
+
+ + + + + + + + + + + + + + + + + + +
evmc_create_fn evmc_load (const char * filename,
enum evmc_loader_error_code * error_code 
)
+
+ +

Dynamically loads the EVMC module with a VM implementation.

+

This function tries to open a dynamically loaded library (DLL) at the given filename. On UNIX-like systems dlopen() function is used. On Windows LoadLibrary() function is used.

+

If the file does not exist or is not a valid shared library the EVMC_LOADER_CANNOT_OPEN error code is signaled and NULL is returned.

+

After the DLL is successfully loaded the function tries to find the EVM create function in the library. The filename is used to guess the EVM name and the name of the create function. The create function name is constructed by the following rules. Consider example path: "/ethereum/libexample-interpreter.so.1.0".

    +
  • the filename is taken from the path: "libexample-interpreter.so.1.0",
    • +
  • the "lib" prefix and all file extensions are stripped from the name: "example-interpreter"
    • +
  • all "-" are replaced with "_" to construct base name: "example_interpreter",
    • +
  • the function name "evmc_create_" + base name is searched in the library: "evmc_create_example_interpreter",
    • +
  • if the function is not found, the function name "evmc_create" is searched in the library.
    • +
+

If the create function is found in the library, the pointer to the function is returned. Otherwise, the EVMC_LOADER_SYMBOL_NOT_FOUND error code is signaled and NULL is returned.

+

It is safe to call this function with the same filename argument multiple times (the DLL is not going to be loaded multiple times).

+
Parameters
+ + + +
filenameThe null terminated path (absolute or relative) to an EVMC module (dynamically loaded library) containing the VM implementation. If the value is NULL, an empty C-string or longer than the path maximum length the EVMC_LOADER_INVALID_ARGUMENT is signaled.
error_codeThe pointer to the error code. If not NULL the value is set to EVMC_LOADER_SUCCESS on success or any other error code as described above.
+
+
+
Returns
The pointer to the EVM create function or NULL in case of error.
+ +
+
+ +

◆ evmc_load_and_configure()

+ +
+
+ + + + + + + + + + + + + + + + + + +
struct evmc_vm * evmc_load_and_configure (const char * config,
enum evmc_loader_error_code * error_code 
)
+
+ +

Dynamically loads the EVMC module, then creates and configures the VM instance.

+

This function performs the following actions atomically:

    +
  • loads the EVMC module (as evmc_load()),
    • +
  • creates the VM instance,
    • +
  • configures the VM instance with options provided in the config parameter.
    • +
+

The configuration string (config) has the following syntax: 

<path> ("," <option-name> ["=" <option-value>])*
+

In this syntax, an option without a value can be specified (,option,) as a shortcut for using empty value (,option=,).

+

Options are passed to a VM in the order they are specified in the configuration string. It is up to the VM implementation how to handle duplicated options and other conflicts.

+

Example configuration string: 

./modules/vm.so,engine=compiler,trace,verbosity=2
+

The function signals the same errors as evmc_load_and_create() and additionally:

+
Parameters
+ + + +
configThe path to the EVMC module with additional configuration options.
error_codeThe pointer to the error code. If not NULL the value is set to EVMC_LOADER_SUCCESS on success or any other error code as described above.
+
+
+
Returns
The pointer to the created VM or NULL in case of error.
+ +
+
+ +

◆ evmc_load_and_create()

+ +
+
+ + + + + + + + + + + + + + + + + + +
struct evmc_vm * evmc_load_and_create (const char * filename,
enum evmc_loader_error_code * error_code 
)
+
+ +

Dynamically loads the EVMC module and creates the VM instance.

+

This is a macro for creating the VM instance with the function returned from evmc_load(). The function signals the same errors as evmc_load() and additionally:

+

It is safe to call this function with the same filename argument multiple times: the DLL is not going to be loaded multiple times, but the function will return new VM instance each time.

+
Parameters
+ + + +
filenameThe null terminated path (absolute or relative) to an EVMC module (dynamically loaded library) containing the VM implementation. If the value is NULL, an empty C-string or longer than the path maximum length the EVMC_LOADER_INVALID_ARGUMENT is signaled.
error_codeThe pointer to the error code. If not NULL the value is set to EVMC_LOADER_SUCCESS on success or any other error code as described above.
+
+
+
Returns
The pointer to the created VM or NULL in case of error.

EVMC Host Implementation Guide
+
+
+

+

‍How to bring EVMC support to Your Ethereum Client.

+
+

+Host interface

+

First of all, you have to implement the Host interface. The Host interface allows VMs to query and modify Ethereum state during the execution.

+

The implementation can be done in object-oriented manner. The evmc_host_interface lists the methods any Host must implement.

+

Moreover, each of the methods has a pointer to evmc_host_context as a parameter. The context is owned entirely by the Host allowing a Host instance to behave as an object with data.

+

+VM usage

+

When Host implementation is ready it's time to start using EVMC VMs.

+
    +
  1. Firstly, create a VM instance. You need to know what is the name of the "create" function in particular VM implementation. The EVMC recommends to name the function by the VM codename, e.g. evmc_create_example_vm(). Invoking the create function will give you the VM instance (evmc_vm). It is recommended to create the VM instance once.
    2. +
  2. If you are interested in loading VMs dynamically (i.e. to use DLLs) check out the EVMC Loader library.
    3. +
  3. The evmc_vm contains information about the VM like name (evmc_vm::name) or ABI version (evmc_vm::abi_version) and methods.
    4. +
  4. To execute code in the VM use the "execute()" method (evmc_vm::execute). You will need:
      +
    • the code to execute,
      • +
    • the message (evmc_message) object that describes the execution context,
      • +
    • the Host instance, passed as evmc_host_context pointer.
      • +
    +
    5. +
  5. When execution finishes you will receive evmc_result object that describes the results of the execution.
    6. +
+

Have fun!

EVMC – Ethereum Client-VM Connector API
+
+
+

ABI version 12

+

The EVMC is the low-level ABI between Ethereum Virtual Machines (EVMs) and Ethereum Clients. On the EVM-side it supports classic EVM1 and ewasm. On the Client-side it defines the interface for EVM implementations to access Ethereum environment and state.

+

+Guides

+ +

+Versioning

+

The EVMC project uses Semantic Versioning. The version format is MAJOR.MINOR.PATCH.

+

The MAJOR version number is also referenced as the EVMC ABI version. This ABI version is available to VM and Host implementations by EVMC_ABI_VERSION. For example EVMC 3.2.1 would have ABI version 3 and therefore this project release can be referenced as EVMC ABIv3 or just EVMC 3. Every C ABI breaking change requires increasing the MAJOR version number.

+

The releases with MINOR version change allow adding new API features and modifying the language bindings API. Backward incompatible API changes are allowed but should be avoided if possible.

+

The releases with PATCH should only include bug fixes. Exceptionally, API changes are allowed when required to fix a broken feature.

+

    EVM Storage Change Status
    +
    +
    +

    The description of evmc_storage_status enum design and its relation to the specification in EIP-2200 and others.

    +

    +Specification

    +
    +

    ‍This is the EIP-2200 specification with modifications:

      +
    • the clause tree has been converted to ordered lists to be referenceable,
      • +
    • the cost constant names has been replaced with matching Yellow Paper names.
      • +
    +
    +
      +
    1. If gasleft is less than or equal to gas stipend, fail the current call frame with 'out of gas' exception.
      2. +
    2. If current value equals new value (this is a no-op), Gwarmaccess is deducted.
      3. +
    3. If current value does not equal new value
        +
      1. If original value equals current value (this storage slot has not been changed by the current execution context)
          +
        1. If original value is 0, Gsset is deducted.
          2. +
        2. Otherwise, Gsreset gas is deducted.
            +
          1. If new value is 0, add Rsclear gas to refund counter.
            2. +
          +
          3. +
        +
        2. +
      2. If original value does not equal current value (this storage slot is dirty), Gwarmaccess gas is deducted. Apply both of the following clauses.
          +
        1. If original value is not 0
            +
          1. If current value is 0 (also means that new value is not 0), remove Rsclear gas from refund counter.
            2. +
          2. If new value is 0 (also means that current value is not 0), add Rsclear gas to refund counter.
            3. +
          +
          2. +
        2. If original value equals new value (this storage slot is reset)
            +
          1. If original value is 0, add Gsset - Gwarmaccess to refund counter.
            2. +
          2. Otherwise, add Gsreset - Gwarmaccess gas to refund counter.
            3. +
          +
          3. +
        +

    +Efficient implementation

    +

    All distinctive storage change statuses can be unambiguously selected by combination of the 4 following checks:

      +
    • o ≠ c, i.e. original != current (dirty),
      • +
    • o = v, i.e original == new (restored),
      • +
    • c ≠ 0, i.e current != 0,
      • +
    • v ≠ 0, i.e new != 0.

    Detailed Description

    +
    template<typename BaseIterator, bool predicate(typename std::iterator_traits< BaseIterator >::value_type) noexcept>
    +struct evmc::filter_iterator< BaseIterator, noexcept >

    The filter iterator adaptor creates a view of an iterator range in which some elements of the range are skipped.

    +

    A predicate function controls which elements are skipped. When the predicate is applied to an element, if it returns true then the element is retained and if it returns false then the element is skipped over. When skipping over elements, it is necessary for the filter adaptor to know when to stop so as to avoid going past the end of the underlying range. A filter iterator is therefore constructed with pair of iterators indicating the range of elements in the unfiltered sequence to be traversed.

    +

    Similar to boost::filter_iterator.

    Detailed Description

    +

    The Host interface.

    +

    The set of all callback functions expected by VM instances. This is C realisation of vtable for OOP interface (only virtual methods, no data). Host implementations SHOULD create constant singletons of this (similarly to vtables) to lower the maintenance and memory management cost.

    + +

    The amount of gas left after the execution.

    +

    If evmc_result::status_code is neither EVMC_SUCCESS nor EVMC_REVERT the value MUST be 0.

    + +

    ◆ gas_refund

    + +
    +
    + + + + +
    int64_t evmc_result::gas_refund
    +
    + +

    The refunded gas accumulated from this execution and its sub-calls.

    +

    The transaction gas refund limit is not applied. If evmc_result::status_code is other than EVMC_SUCCESS the value MUST be 0.

    + +

    +
    + +

    ◆ output_data

    + +
    +
    + + + + +
    const uint8_t* evmc_result::output_data
    +
    + +

    The reference to output data.

    +

    The output contains data coming from RETURN opcode (iff evmc_result::code field is EVMC_SUCCESS) or from REVERT opcode.

    +

    The memory containing the output data is owned by EVM and has to be freed with evmc_result::release().

    +

    This pointer MAY be NULL. If evmc_result::output_size is 0 this pointer MUST NOT be dereferenced.

    + +

    Definition at line 448 of file evmc.h.

    + +
    +
    + +

    ◆ output_size

    + +
    +
    + + + + +
    size_t evmc_result::output_size
    +
    + +

    The size of the output data.

    +

    If evmc_result::output_data is NULL this MUST be 0.

    + +

    Definition at line 455 of file evmc.h.

    + +
    +
    + +

    ◆ padding

    + +
    +
    + + + + +
    uint8_t evmc_result::padding[4]
    +
    + +

    Reserved data that MAY be used by a evmc_result object creator.

    +

    This reserved 4 bytes together with 20 bytes from create_address form 24 bytes of memory called "optional data" within evmc_result struct to be optionally used by the evmc_result object creator.

    +
    See also
    evmc_result_optional_data, evmc_get_optional_data().
    +

    Also extends the size of the evmc_result to 64 bytes (full cache line).

    + +

    Definition at line 499 of file evmc.h.

    + +

    ◆ release

    + +
    +
    + + + + +
    evmc_release_result_fn evmc_result::release
    +
    + +

    The method releasing all resources associated with the result object.

    +

    This method (function pointer) is optional (MAY be NULL) and MAY be set by the VM implementation. If set it MUST be called by the user once to release memory and other resources associated with the result object. Once the resources are released the result object MUST NOT be used again.

    +

    The suggested code pattern for releasing execution results:

    struct evmc_result result = ...;
    +
    if (result.release)
    +
    result.release(&result);
    +
    evmc_result
    The EVM code execution result.
    Definition: evmc.h:416
    +
    evmc_result::release
    evmc_release_result_fn release
    The method releasing all resources associated with the result object.
    Definition: evmc.h:476
    +
    Note
    It works similarly to C++ virtual destructor. Attaching the release function to the result itself allows VM composition.
    + +

    Definition at line 476 of file evmc.h.

    + +
    +
    + +

    ◆ status_code

    + +
    +
    + + + + +
    enum evmc_status_code evmc_result::status_code
    +
    + +

    The execution status code.

    EVMC VM Implementation Guide

    +

    ‍How to add EVMC interface to Your Ethereum VM implementation.

    +
    +

    +An example

    +

    You can start with the example implementation of EVMC VM interface in C++.

    +

    +VM instance

    +

    The VM instance is described by the evmc_vm struct. It contains the basic static information about the VM like name and version. The struct also includes the VM methods (in form of function pointers) to allow the Host to interact with the VM.

    +

    Some methods are optional. The VM must implement at least all mandatory ones.

    +

    The instance struct must also include the EVMC ABI version (EVMC_ABI_VERSION) it was build with. This allows the Host to check the ABI compatibility when loading VMs dynamically.

    +

    The VM instance is created and returned as a pointer from a special "create" function. The EVMC recommends to name the function by the VM codename, e.g. evmc_create_example_vm().

    +

    +VM methods implementation

    +

    Each VM methods takes the pointer to the evmc_vm as the first argument. The VM implementation can extend the evmc_vm struct for storing internal data. This allow implementing the VM in object-oriented manner.

    +

    The most important method is evmc_vm::execute() because it executes EVM code. Remember that the Host is allowed to invoke the execute method concurrently so do not store data related to a particular execution context in the VM instance.

    +

    Before a client can actually execute a VM, it is important to implement the three basic fields for querying name (evmc_vm::name), version (evmc_vm::version) and capabilities (evmc_vm::get_capabilities()) as well as the evmc_vm::destroy() method to wind the VM down.

    +

    Other methods are optional.

    +

    +Resource management

    +

    All additional resources allocated when the VM instance is created must be freed when the destroy method is invoked.

    +

    The VM implementation can also attach additional resources to the evmc_result of an execution. These resource must be freed when the evmc_result::release() method is invoked.

    +

    Have fun!

    EVMC VM Tester
    +
    +
    +

    The EVMC project contains a EVMC-compatibility testing tool for VM implementations.

    +

    The tool is called evmc-vmtester and to include it in the EVMC build add -DEVMC_TESTING=ON CMake option to the project configuration step.

    +

    Usage is simple as

    +
    evmc-vmtester [vm]
    +

    where [vm] is a path to a shared library with VM implementation.

    +

    For more information check evmc-vmtester --help.
