Some autoconf tests use module level inline asm to test compiler's handling of · eee86452

Evan Cheng authored Aug 24, 2011

.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc. · bbf3b0de

There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.
