libstdc++: Workaround kernel-headers on s390x-linux
We see
FAIL: 17_intro/headers/c++1998/all_attributes.cc (test for excess errors)
FAIL: 17_intro/headers/c++2011/all_attributes.cc (test for excess errors)
FAIL: 17_intro/headers/c++2014/all_attributes.cc (test for excess errors)
FAIL: 17_intro/headers/c++2017/all_attributes.cc (test for excess errors)
FAIL: 17_intro/headers/c++2020/all_attributes.cc (test for excess errors)
FAIL: 17_intro/names.cc -std=gnu++17 (test for excess errors)
on s390x-linux.
The first 5 are due to kernel-headers not using uglified attribute names,
where <asm/types.h> contains
__attribute__((packed, aligned(4)))
I've filed a downstream bugreport for this in
https://bugzilla.redhat.com/show_bug.cgi?id=2276084
(not really sure where to report kernel-headers issues upstream), while the
last one is due to <sys/ucontext.h> from glibc containing:
#ifdef __USE_MISC
# define __ctx(fld) fld
#else
# define __ctx(fld) __ ## fld
#endif
...
typedef union
{
double __ctx(d);
float __ctx(f);
} fpreg_t;
and g++ predefining -D_GNU_SOURCE which implies define __USE_MISC.
The following patch adds a workaround for this on the libstdc++ testsuite
side.
