[LLVMdev] Using address space attribute in LLVM

[Juan Carlos Martinez Santos]

Hello Chris,

My first impression was that LLVM-GCC does not support section attribute,
but it was my bad. I was trying to specify a section attribute for a local
variable. When I run the test in clang... it works as I expected; however,
later I realized that both gcc and llvm-gcc do not allow it.

My question is still live... why is the reason for that?

Regards,

Juan Carlos

Yes. llvm does not allow to specify a section attribute for local variables,
but clang does.

No. in this case, gcc and llvm-gcc generate the same error.
