ComputeMux compiler implementations are not required to support any of the following features:

• Recursion

• Function pointers

• Dynamic allocation

  • All allocations shall be statically sized and occur in the prologue of a given function.

• Dynamic stack sizes

  • With no recursion or dynamic allocation, the maximum stack size is known at compile time.

• Exception-handling

• Garbage collection

• C runtime (CRT) support

• Debug information (which is optional)

• Half-precision floating-point, if unsupported

• Double-precision floating-point, if unsupported

• Dynamic linking (if the compiler implementation never emits external calls e.g., to LLVM’s compiler-rt)

  • The ability to link against a small support library including compiler-rt and functions like memcpy/memset can help to simplify the compiler implementation and produce smaller code, but is not required.

• A full tool-chain: custom binary formats are permitted
