There is one usage in boehm-gc/os_dep.c, but it is only used if SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or FREEBSD is defined, which are all not using Linux-based glibc ports. Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for __FreeBSD__. config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and config/s390/linux-unwind.h also uses a constant. I tested the following patch for sh-linux-gnu. This only covers one configuration, but the change is pretty mechanic anyway and every place that used to refer to struct siginfo already must have had <signal.h> in its include path, which is the same file that declares siginfo_t. OK to commit? This should probably also go into any active release branches, to keep them buildable once this glibc change ripples through? libgcc/ * config/alpha/linux-unwind.h (alpha_fallback_frame_state): Use siginfo_t instead of struct siginfo. * config/bfin/linux-unwind.h (bfin_fallback_frame_state): Likewise. * config/i386/linux-unwind.h (x86_fallback_frame_state): Likewise. * config/ia64/linux-unwind.h (ia64_fallback_frame_state) (ia64_handle_unwabi): Likewise. * config/mips/linux-unwind.h (mips_fallback_frame_state): Likewise. * config/pa/linux-unwind.h (pa32_fallback_frame_state): Likewise. * config/sh/linux-unwind.h (shmedia_fallback_frame_state) (sh_fallback_frame_state): Likewise. * config/tilepro/linux-unwind.h (tile_fallback_frame_state): Likewise. * config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Likewise. diff --git a/libgcc/config/alpha/linux-unwind.h b/libgcc/config/alpha/linux-unwind.h index 4c811dc..f747053 100644 --- a/libgcc/config/alpha/linux-unwind.h +++ b/libgcc/config/alpha/linux-unwind.h @@ -49,7 +49,7 @@ alpha_fallback_frame_state (struct _Unwind_Context *context, else if (pc[1] == 0x201f015f) /* lda $0,NR_rt_sigreturn */ { struct rt_sigframe { - struct siginfo info;
