Joseph Myers 3d452dabd1 Fix uc_* namespace (bug 21457). ... The standard members of ucontext_t, in all standard versions with that type, are uc_link, uc_sigmask, uc_stack and uc_mcontext. The uc_* namespace is mostly reserved for additions to the structure. However, in XPG4.2, it's only reserved when <ucontext.h> is included, not when <signal.h> is included, while <signal.h> is required to define ucontext_t (but not allowed to make visible other symbols from <ucontext.h>). Thus, nonstandard members should avoid uc_* names. Some already do use __uc_*, but others don't; most architectures (all except ia64, I think) have a member uc_flags and some have additional members beyond that. This patch makes nonstandard members have an __ prefix unless __USE_MISC is defined. Members whose names indicate they are solely padding / reserved for future use are renamed unconditionally to use the __glibc_reserved1 naming convention. This is part of the preparation for a revised version of the mcontext_t / sigcontext patch to be able to eliminate all 13 of the miscellaneous XFAILs in conform/Makefile, rather than only 11 of them as at present (at least one further fix on top of this one will be needed for that as well). Tested for x86_64, and with build-many-glibcs.py. [BZ #21457] * sysdeps/arm/sys/ucontext.h (__ctx): Move undefine further down. (ucontext_t): Use __ctx with uc_flags.
