Module cmse

Functionsยง

  • Returns whether the inputs will fit into the available registers
  • Returns whether the output will fit into the available registers
  • validate_cmse_abi ๐Ÿ”’
    Check conditions on inputs and outputs that the cmse ABIs impose: arguments and results MUST be returned via registers (i.e. MUST NOT spill to the stack). LLVM will also validate these conditions, but by checking them here rustc can emit nicer error messages.
