Re: [gem5-users] How can I make my custom x86 macro op be recognized from GCC

[Abhishek Singh]

Hi,
Instead macro op name use the opcode
Eg

 __asm__(".byte 0xcc, 0x00, 0xcc");

You will need to have complete knowledge up on representing register names
using opcode

You can find it x86 intel manual

[gem5-users] How can I make my custom x86 macro op be recognized from GCC

[Muhammad Aamir]

Hi everyone,

I have made a custom x86 macro op and I wish to simulate its effects but to
do that I need it to be recognized in my C code(am using my custom macroop
via inline assembly). but it will not compile as GCC wont recognize it as
it is not a basic x86 instruction. Is there anyway e.g. by using m5ops or
something similar which can make my custom instruction to be accepted by
GCC or do I have to edit GCC to recognize it.
