           Summary: Inline assembler can't use enum values as parameters.
           Product: D
           Version: 1.026
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: burton-radons@shaw.ca


The inline assembler rejects any attempt to use an enum value as a parameter:

        enum
        {
                enumeration = 1,
        }

        void test ()
        {
                asm
                {
                        mov EAX, enumeration;
                }
        }

This code fails compilation with "bad type/size of operands 'enumeration'", regardless of whether enum is given a type or if AX or AH is attempted instead. It should be equivalent to "mov EAX, 1;".

The workaround is to assign the enumeration value to a const value before the asm statement.

Did you intend for B-D to succeed in the current compiler, Thomas? Because you assign "const dummy = enumeration;" in them but you continue to use "enumeration" in the asm code.
