The format of /proc depends on the data model 37 of the observer (the controlling process, GDB in our case). The 38 Solaris header files conveniently define PR_MODEL_NATIVE to the 39 data model of the controlling process. If its value is 40 PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit 41 program. 42 43 GNU/Linux uses the same formats as Solaris for its core files (but 44 not for ptrace(2)). The GNU/Linux headers don't define 45 PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define 46 provided by GCC to determine the appropriate data model. 47 48 Note that a 32-bit GDB won't be able to debug a 64-bit target 49 process using /proc on Solaris. */ 50 51 #if (defined (__arch64__) || \ 52 (defined (PR_MODEL_NATIVE) && (PR_MODEL_NATIVE == PR_MODEL_LP64))) 53 54 #include "sparc64-tdep.h" 55 56 #define sparc_supply_gregset sparc64_supply_gregset 57 #define sparc_supply_fpregset sparc64_supply_fpregset 58 #define sparc_collect_gregset sparc64_collect_gregset 59 #define sparc_collect_fpregset sparc64_collect_fpregset 60 61 #define sparc_sol2_gregmap sparc64_sol2_gregmap 62 #define sparc_sol2_fpregmap sparc64_sol2_fpregmap 63 64 #else 65 66 #define sparc_supply_gregset sparc32_supply_gregset 67 #define sparc_supply_fpregset sparc32_supply_fpregset 68 #define sparc_collect_gregset sparc32_collect_gregset 69 #define sparc_collect_fpregset sparc32_collect_fpregset 70 71 #define sparc_sol2_gregmap sparc32_sol2_gregmap 72 #define sparc_sol2_fpregmap sparc32_sol2_fpregmap 73 74 #endif 75 76 void 77 supply_gregset (struct regcache *regcache, const prgregset_t *gregs) 78 { 79 sparc_supply_gregset (&sparc_sol2_gregmap, regcache, -1, gregs); 80 } 81 82 void 83 supply_fpregset (struct regcache *regcache, const prfpregset_t *fpregs) 84 { 85 sparc_supply_fpregset (&sparc_sol2_fpregmap, regcache, -1, fpregs); 86 } 87 88 void 89 fill_gregset (const struct regcache *regcache, prgregset_t *gregs, int regnum) 90 { 91 sparc_collect_gregset (&sparc_sol2_gregmap, regcache, regnum, gregs); 92 } 93 94 void 95 fill_fpregset (const struct regcache *regcache, 96 prfpregset_t *fpregs, int regnum) 97 { 98 sparc_collect_fpregset (&sparc_sol2_fpregmap, regcache, regnum, fpregs); 99 } 100 101 /* Provide a prototype to silence -Wmissing-prototypes. */ 102 extern initialize_file_ftype _initialize_sparc_sol2_nat; 103 104 void 105 _initialize_sparc_sol2_nat (void) 106 { 107 struct target_ops *t; 108 109 t = procfs_target (); 110 #ifdef NEW_PROC_API /* Solaris 6 and above can do HW watchpoints. */ 111 procfs_use_watchpoints (t); 112 #endif 113 add_target (t); 114 } 115
