…a-xyz#4) * [BPF] Make rust allocation builtins unavailable for BPF target - the calls to rust alloc/dealloc routines need to be preserved and not replaced by compiler generated builtin inlined code
* [SOL][BPF] Adjust BPF tests * [SOL][BPF] Improve reporting of stack size is too large - issue only one warning for each function - report the function location if debug information is available
Co-authored-by: Jack May <[email protected]>
* [SOL] Make lld thread-safe with llvm when used in-process Every time Solang tries to link a web-assembly file in-process, the linker re-inits llvm which is not thread-safe with the rest of solang. Signed-off-by: Sean Young <[email protected]> * [SOL][BPF] Enable the _ExtInt extension on the BPF Target for Solana Signed-off-by: Sean Young <[email protected]>
Solana extends BPF so that structs type information is not fully supported in BTF. This leads to ICE crashes and some unsupported relocations being emitted in binary files that linker errors on. For, now the debug information is simply disabled when compiling for Solana to avoid the errors in Debug builds.
* Fix issue with copying 16-byte aligned memory

Besides the basic adjustments for Rust 1.79, I included here the implementation of atomic load and store and atomic swap as they were now necessary to compiler Rust 1.79. I registered the SBF target and removed the debug checks for relocations in the linker. The latter is not implemented for the SBF target, but it is used in the Rust test suit. |

Besides cherry-picking the commits, I added a panic in the BPF target when someone tries to use it with Solana. The upstream BPF target accumulated too many changes that conflict with our previous ones, so I'm dropping the support for it. The next release won't include changes in the BPF target.
