Statements

General

CoreDSL 2 supports the following standard C constructs:

• Branches: if / else, switch / case / default
• Loops: for / while / do...while
• Jumps: continue / break

Function recursion and irreducible control flow are prohibited.

Spawn keyword

Note: This section is outdated and will be rewritten soon

The spawn keyword marks a statement (usually, a compound statement or a function call) for asynchronous execution. Spawn statements are only allowed as the last statement of an instruction's behavior specification (this implies that such statements cannot be nested. Semantically, the execution of the instruction ends at the spawned statement, which itself continues to execute in the background.

Example from the introduction

Multiple spawn statements may overlap at runtime. Hence, the implementation must define an arbitration mechanism to access shared resources such as register files or address spaces.
