This requires +various linux-unwind.h files in libgcc, that were previously using +struct ucontext, to be fixed to use ucontext_t instead. This is +similar to the removal of the struct siginfo tag from siginfo_t some +years ago. + +This patch changes those files to use ucontext_t instead. As the +standard name that should be unconditionally safe, so this is not +restricted to architectures supported by glibc, or conditioned on the +glibc version. + +Tested compilation together with current glibc with glibc's +build-many-glibcs.py. + + * config/aarch64/linux-unwind.h (aarch64_fallback_frame_state), + config/alpha/linux-unwind.h (alpha_fallback_frame_state), + config/bfin/linux-unwind.h (bfin_fallback_frame_state), + config/i386/linux-unwind.h (x86_64_fallback_frame_state, + x86_fallback_frame_state), config/m68k/linux-unwind.h (struct + uw_ucontext), config/nios2/linux-unwind.h (struct nios2_ucontext), + config/pa/linux-unwind.h (pa32_fallback_frame_state), + config/sh/linux-unwind.h (sh_fallback_frame_state), + config/tilepro/linux-unwind.h (tile_fallback_frame_state), + config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Use + ucontext_t instead of struct ucontext. + + +git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-6-branch at 249957 138bc75d-0d04-0410-961f-82ee72b054a4 +[Romain cherry-pick from gcc-6-branch] +Signed-off-by: Romain Naour +--- + libgcc/config/aarch64/linux-unwind.h | 2 +- + libgcc/config/alpha/linux-unwind.h | 2 +- + libgcc/config/bfin/linux-unwind.h | 2 +- + libgcc/config/i386/linux-unwind.h | 4 ++-- + libgcc/config/m68k/linux-unwind.h | 2 +- + libgcc/config/nios2/linux-unwind.h | 2 +- + libgcc/config/pa/linux-unwind.h | 2 +- + libgcc/config/sh/linux-unwind.h | 2 +- + libgcc/config/tilepro/linux-unwind.h | 2 +- + libgcc/config/xtensa/linux-unwind.h | 2 +- + 11 files changed, 25 insertions(+), 11 deletions(-) + +diff --git a/libgcc/config/aarch64/linux-unwind.h b/libgcc/config/aarch64/linux-unwind.h +index 4512efb..06de45a 100644 +--- a/libgcc/config/aarch64/linux-unwind.h ++++ b/libgcc/config/aarch64/linux-unwind.h +@@ -52,7 +52,7 @@ aarch64_fallback_frame_state (struct _Unwind_Context *context, + struct rt_sigframe + { + siginfo_t info; +- struct ucontext uc; ++ ucontext_t uc; + }; + + struct rt_sigframe *rt_; +diff --git a/libgcc/config/alpha/linux-unwind.h b/libgcc/config/alpha/linux-unwind.h +index bdbba4a..e84812e 100644 +--- a/libgcc/config/alpha/linux-unwind.h ++++ b/libgcc/config/alpha/linux-unwind.h +@@ -51,7 +51,7 @@ alpha_fallback_frame_state (struct _Unwind_Context *context, + { + struct rt_sigframe { + siginfo_t info; +- struct ucontext uc; ++ ucontext_t uc; + } *rt_ = context->cfa; + sc = &rt_->uc.uc_mcontext; + } +diff --git a/libgcc/config/bfin/linux-unwind.h b/libgcc/config/bfin/linux-unwind.h +index 77b7c23..8bf5e82 100644 +--- a/libgcc/config/bfin/linux-unwind.h ++++ b/libgcc/config/bfin/linux-unwind.h +@@ -52,7 +52,7 @@ bfin_fallback_frame_state (struct _Unwind_Context *context, + void *puc; + char retcode[8]; + siginfo_t info; +- struct ucontext uc; ++ ucontext_t uc; + } *rt_ = context->cfa; + + /* The void * cast is necessary to avoid an aliasing warning. +diff --git a/libgcc/config/i386/linux-unwind.h b/libgcc/config/i386/linux-unwind.h +index 540a0a2..29efbe3 100644 +--- a/libgcc/config/i386/linux-unwind.h ++++ b/libgcc/config/i386/linux-unwind.h +@@ -58,7 +58,7 @@ x86_64_fallback_frame_state (struct _Unwind_Context *context, + if (*(unsigned char *)(pc+0) == 0x48 + && *(unsigned long long *)(pc+1) == RT_SIGRETURN_SYSCALL) + { +- struct ucontext *uc_ = context->cfa; ++ ucontext_t *uc_ = context->cfa; + /* The void * cast is necessary to avoid an aliasing warning. + The aliasing warning is correct, but should not be a problem + because it does not alias anything. */ +@@ -138,7 +138,7 @@ x86_fallback_frame_state (struct _Unwind_Context *context, + siginfo_t *pinfo; + void *puc; + siginfo_t info; +- struct ucontext uc; ++ ucontext_t uc; + } *rt_ = context->cfa; + /* The void * cast is necessary to avoid an aliasing warning. + The aliasing warning is correct, but should not be a problem +diff --git a/libgcc/config/m68k/linux-unwind.h b/libgcc/config/m68k/linux-unwind.h +index 75b7cf7..f964e24 100644 +--- a/libgcc/config/m68k/linux-unwind.h ++++ b/libgcc/config/m68k/linux-unwind.h +@@ -33,7 +33,7 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
