I've been looking through questions on here and the internet for a while now and I cannot seem to find out whether or not it is possible to do inline assembly with GCC using something other than GAS. I am trying to find if I can avoid using not only GAS's AT&T syn开发者_C百科tax (though, I know how to use Intel syntax with GAS) but the extended asm format. While this is not for a project or anything other than my own curiosity, I would really appreciate any help I can get (this is actually my first question here because I could not find an answer about it)! Also, if this makes any difference, I'm currently using DevC++ (for C code, not C++) on Windows.
Thanks, Tom
You can link the output from an assembler (a ".o" or ".obj" file) with your C or C++ program. Put your assembler code in a text file. Your IDE or makefile will assemble it just as it would any c source file. The only tricky bit is learning how to interface between the two different systems.
You cannot use another inline assembly syntax with GCC. inline assembly is implemented by GCC literally including the assembly you write inline with its own (textual) assembly output, which it then sends to gas
to be assembled. Since GCC doesn't know how to change the format of its own output to feed to another assembler, you can't change the inline assembly, either.
