LLVM ERROR: Error parsing inline asm
Only problem seems to be that the parser finalizes OutStreamer
at the end of the first inline asm, which isn't what we want.
For example:
$ cat asm.c
int foo(int X) {
__asm__ ("incl %0" : "+r" (X));
return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
subq $8, %rsp
movl %edi, (%rsp)
movl %edi, %eax
## InlineAsm Start
incl %eax
## InlineAsm End
movl %eax, (%rsp)
movl %eax, 4(%rsp)
addq $8, %rsp
ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000 subq $0x08,%rsp
0000000000000004 movl %edi,(%rsp)
0000000000000007 movl %edi,%eax
0000000000000009 incl %eax
$
don't stop at inc!
