Summary: __builtin_types_compatible_p does not take in account
noreturn attributes
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
This code compiles in gcc, but not in clang due to different result.
The two types are considered incompatible by gcc and compatible by clang.
typedef void (*f1)();
typedef void (*f2)() __attribute__ ((noreturn));
int p() {
int a[1 - __builtin_types_compatible_p(f1, f2) * 2];
}
