The format of /proc depends on the data model of the observer (the controlling process, GDB in our case). The Solaris header files conveniently define PR_MODEL_NATIVE to the data model of the controlling process. If its value is PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit program. GNU/Linux uses the same formats as Solaris for its core files (but not for ptrace(2)). The GNU/Linux headers don't define PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define provided by GCC to determine the appropriate data model. Note that a 32-bit GDB won't be able to debug a 64-bit target process using /proc on Solaris. */ #if (defined (__arch64__) || \ (defined (PR_MODEL_NATIVE) && (PR_MODEL_NATIVE == PR_MODEL_LP64))) #include "sparc64-tdep.h" #define sparc_supply_gregset sparc64_supply_gregset #define sparc_supply_fpregset sparc64_supply_fpregset #define sparc_collect_gregset sparc64_collect_gregset #define sparc_collect_fpregset sparc64_collect_fpregset #define sparc_sol2_gregset sparc64_sol2_gregset #define sparc_sol2_fpregset sparc64_sol2_fpregset #else #define sparc_supply_gregset sparc32_supply_gregset #define sparc_supply_fpregset sparc32_supply_fpregset #define sparc_collect_gregset sparc32_collect_gregset #define sparc_collect_fpregset sparc32_collect_fpregset #define sparc_sol2_gregset sparc32_sol2_gregset #define sparc_sol2_fpregset sparc32_sol2_fpregset #endif void supply_gregset (struct regcache *regcache, const prgregset_t *gregs) { sparc_supply_gregset (&sparc_sol2_gregset, regcache, -1, gregs); } void supply_fpregset (struct regcache *regcache, const prfpregset_t *fpregs) { sparc_supply_fpregset (regcache, -1, fpregs); } void fill_gregset (const struct regcache *regcache, prgregset_t *gregs, int regnum) { sparc_collect_gregset (&sparc_sol2_gregset, regcache, regnum, gregs); } void fill_fpregset (const struct regcache *regcache, prfpregset_t *fpregs, int regnum) { sparc_collect_fpregset (regcache, regnum, fpregs); } /* Provide a prototype to silence -Wmissing-prototypes. */ extern initialize_file_ftype _initialize_sparc_sol2_nat; void _initialize_sparc_sol2_nat (void) { struct target_ops *t; t = procfs_target (); #ifdef NEW_PROC_API /* Solaris 6 and above can do HW watchpoints */ procfs_use_watchpoints (t); #endif add_target (t); }
