Bug ID: 21022
Summary: MS ABI: intrin_type not handled at all, functions
returning vectors miscompiled
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
consider:
struct __declspec(intrin_type) __m128i {
char x;
};
__m128i f(__m128i *x) {
return *x;
}
we codegen this to:
"?f@@YA?AU__m128i@@PAU1@@Z":
movl 4(%esp), %eax
movb (%eax), %al
retl
However, MSVC will instead do something like this:
"?f@@YA?AU__m128i@@PAU1@@Z":
movl 4(%esp), %eax
movdqa (%eax), %xmm0
retl
