<div>
<pre>When using both imm and dot operator in an inline asm operand the generated ir
and asm are wrong.
Consider the code:
typedef struct foo {
int x;
int y;
} foo;
int main(){
__asm {mov eax, 3[rbx]foo.y}
return 0;
}
compiling with clang -cc1 -fasm-blocks -emit-llvm gives us:
call i32 asm sideeffect inteldialect "mov eax, $$3[ebx].11",
"={eax},~{eax},~{dirflag},~{fpsr},~{flags}"
the foo.y was rewrited as .11 (8+3 instead of 8) while the immediate is still
in the ir - $$3.
when compiling to asm, it's being resolved as 11+3 = 14, instead of 8+3=11.</pre>
