Summary: -Wreturn-type warning for function using
__builtin_expect
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Semantic Analyzer
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Blocks: 5511
Testcase:
int a() { if (__builtin_expect(1,1)) return 1; }
Warns with -Wreturn-type; shouldn't warn because the return is always executed.
This blocks Firefox because it uses a construct like this and
-Werror=return-type.
