C++ (Cpp) Form::is_operand Examples

Example #1

File: archDesc.cpp Project: WillDignazio/hotspot

// Obtain the name of the RegMask for an InstructForm
const char *ArchDesc::reg_mask(InstructForm &inForm) {

               " for this instruction: %s",
               inForm._ident);
    abort();
  }

  // Instructions producing 'Universe' use RegMask::Empty
  if( strcmp(result,"Universe")==0 ) {

  // Lookup this result operand and get its register class
  Form *form = (Form*)_globalNames[result];
