Subject: [PATCH] Wbuiltin-declaration-mismatch-4.c: accept long long in
warning for llp64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
llp64 targets like mingw-w64 will print:
gcc/testsuite/gcc.dg/Wbuiltin-declaration-mismatch-4.c:80:17: warning: ‘memset’ argument 3 promotes to ‘ptrdiff_t’ {aka ‘long long int’} where ‘long long unsigned int’ is expected in a call to built-in function declared without prototype [-
Wbuiltin-declaration-mismatch]
Change the regex pattern to accept it.
Signed-off-by: Jonathan Yong <10wa...@gmail.com>
gcc/testsuite/ChangeLog:
* gcc.dg/Wbuiltin-declaration-mismatch-4.c: Make diagnostic
accept long long.
