libstdc++: Add support for running tests with multiple -std options
caused
FAIL: 23_containers/vector/bool/110807.cc -std=gnu++17 (test for excess errors)
with GCC configured with
../../gcc/configure
--prefix=/export/users/haochenj/src/gcc-bisect/master/master/r14-4046/usr
--enable-clocale=gnu --with-system-zlib --with-demangler-in-ld
--with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl
--enable-libmpx x86_64-linux --disable-bootstrap
To reproduce:
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check
RUNTESTFLAGS="conformance.exp=23_containers/vector/bool/110807.cc
--target_board='unix{-m32}'"
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check
RUNTESTFLAGS="conformance.exp=23_containers/vector/bool/110807.cc
--target_board='unix{-m32\ -march=cascadelake}'"
(If you met problems with cascadelake related, disabling AVX512F in command
line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
