Bug ID: 48159
Summary: Inline asm macros cannot replace instructions
Product: new-bugs
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

Hello,
Inline asm macros are not able to replace instructions, see:
void test(void) {
asm volatile (".macro ret; .error; .endm; .macro retq; .error; .endm");
}
Trying to build the following snippet with gcc will trigger the .error
directive, while it builds fine with all versions of clang I've tested with.
