Subject: [PATCH] testsuite: xfail c-c++-common/pr103798-2.c for C++ on Solaris
[PR113706]
c-c++-common/pr103798-2.c FAILs on Solaris when compiled as C++:
FAIL: c-c++-common/pr103798-2.c -std=gnu++14 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++17 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++20 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++98 scan-assembler-not memchr
As Jason analyzed, Solaris <string.h> declares memchr for C++ as returning
const void * as specified by the C++ standard, while gcc expects the return
type to be void * like in C.
So this patch xfails the test for C++ on Solaris.
Tested on sparc-sun-solaris2.11 and x86_64-pc-linux-gnu.
