Subject: realloc-1.c: accept long long in warning for llp64
X-Git-Tag: basepoints/gcc-16~181

realloc-1.c: accept long long in warning for llp64

llp64 targets like mingw-w64 will print:
warning: ignoring return value of ‘void* __builtin_realloc(void*, long long unsigned int)’ declared with attribute ‘warn_unused_result’ [-Wunused-result]
Change the regex pattern to accept it.

gcc/testsuite/ChangeLog:

	* c-c++-common/analyzer/realloc-1.c: Make diagnostic accept
	long long for __builtin_realloc warning.
