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 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? gcc/ * 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. --- --- a/gcc/config/alpha/linux-unwind.h +++ b/gcc/config/alpha/linux-unwind.h @@ -49,7 +49,7 @@ alpha_fallback_frame_state (struct _Unwi else if (pc[1] == 0x201f015f) /* lda $0,NR_rt_sigreturn */ { struct rt_sigframe { - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_ = context->cfa; sc = &rt_->uc.uc_mcontext; --- a/gcc/config/bfin/linux-unwind.h +++ b/gcc/config/bfin/linux-unwind.h @@ -48,10 +48,10 @@ bfin_fallback_frame_state (struct _Unwin { struct rt_sigframe { int sig; - struct siginfo *pinfo; + siginfo_t *pinfo; void *puc; char retcode[8]; - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_ = context->cfa; --- a/gcc/config/i386/linux-unwind.h +++ b/gcc/config/i386/linux-unwind.h @@ -133,9 +133,9 @@ x86_fallback_frame_state (struct _Unwind { struct rt_sigframe { int sig; - struct siginfo *pinfo; + siginfo_t *pinfo; void *puc; - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_ = context->cfa; /* The void * cast is necessary to avoid an aliasing warning. --- a/gcc/config/ia64/linux-unwind.h +++ b/gcc/config/ia64/linux-unwind.h @@ -47,7 +47,7 @@ ia64_fallback_frame_state (struct _Unwin struct sigframe { char scratch[16]; unsigned long sig_number; - struct siginfo *info; + siginfo_t *info; struct sigcontext *sc; } *frame_ = (struct sigframe *)context->psp; struct sigcontext *sc = frame_->sc; @@ -137,7 +137,7 @@ ia64_handle_unwabi (struct _Unwind_Conte struct sigframe { char scratch[16]; unsigned long sig_number; - struct siginfo *info; + siginfo_t *info; struct sigcontext *sc; } *frame = (struct sigframe *)context->psp; struct sigcontext *sc = frame->sc; --- a/gcc/config/mips/linux-unwind.h +++ b/gcc/config/mips/linux-unwind.h @@ -75,7 +75,7 @@ mips_fallback_frame_state (struct _Unwin struct rt_sigframe { u_int32_t ass[4]; /* Argument save space for o32. */ u_int32_t trampoline[2]; - struct siginfo info; + siginfo_t info; _sig_ucontext_t uc; } *rt_ = context->cfa; sc = &rt_->uc.uc_mcontext; --- a/gcc/config/pa/linux-unwind.h +++ b/gcc/config/pa/linux-unwind.h @@ -63,7 +63,7 @@ pa32_fallback_frame_state (struct _Unwin int i; struct sigcontext *sc; struct rt_sigframe { - struct siginfo info; + siginfo_t info; struct ucontext uc; } *frame; --- a/gcc/config/sh/linux-unwind.h +++ b/gcc/config/sh/linux-unwind.h @@ -80,9 +80,9 @@ shmedia_fallback_frame_state (struct _Un && (*(unsigned long *) (pc+11) == 0x6ff0fff0)) { struct rt_sigframe { - struct siginfo *pinfo; + siginfo_t *pinfo; void *puc; - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_ = context->cfa; /* The void * cast is necessary to avoid an aliasing warning. @@ -179,7 +179,7 @@ sh_fallback_frame_state (struct _Unwind_ && (*(unsigned short *) (pc+14) == 0x00ad)))) { struct rt_sigframe { - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_ = context->cfa; /* The void * cast is necessary to avoid an aliasing warning. --- a/gcc/config/xtensa/linux-unwind.h +++ b/gcc/config/xtensa/linux-unwind.h @@ -62,7 +62,7 @@ xtensa_fallback_frame_state (struct _Unw struct sigcontext *sc; struct rt_sigframe { - struct siginfo info; + siginfo_t info; struct ucontext uc; } *rt_; ='#n31'>31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251
