Description

Could this be looked over and possibly added for some more arches? like PPC etc

setjmp.h on this SPARC box (which is 64 bit but uses 32 bit userspace, thus no SPARC64 identifier, however I expect that SPARC64 may be needed for Solaris on Sparc).

#include <bits/wordsize.h>

#if __WORDSIZE == 64

#ifndef _ASM
typedef struct __sparc64_jmp_buf
  {
    struct __sparc64_jmp_buf    *uc_link;
    unsigned long               uc_flags;
    unsigned long               uc_sigmask;
    struct __sparc64_jmp_buf_mcontext
      {
        unsigned long           mc_gregs[19];
        unsigned long           mc_fp;
        unsigned long           mc_i7;
        struct __sparc64_jmp_buf_fpu
          {
            union
              {
                unsigned int    sregs[32];
                unsigned long   dregs[32];
                long double     qregs[16];
              }                 mcfpu_fpregs;
            unsigned long       mcfpu_fprs;

          }                     mc_fpregs;
      }                         uc_mcontext;
  } __jmp_buf[1];
