From a338618604d020a6e8bde2f5e298a7e41abe290c Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Sat, 31 May 2003 16:08:06 +0000 Subject: From Michal Ludvig : * i386-tdep.h (struct gdbarch_tdep): Add members `sc_reg_offset' and `sc_num_regs'. (I386_EAX_REGNUM, I386_EDX_REGNUM, I386_ESP_REGNUM, I386_EBP_REGNUM, I386_EIP_REGNUM, I386_EFLAGS_REGNUM, I386_ST0_REGNUM): Move here from... * i386-tdep.c: ... here. (I386_NUM_SAVED_REGS): Define to I386_NUM_REGS. (i386_sigtramp_frame_cache): Use `sc_reg_offset' to find saved registers if possible. (i386_gdbarch_init): Initialize TDEP->sc_reg_offset. * i386bsd-tdep.c (i386bsd_sc_pc_offset, i386bsd_sc_sp_offset): Remove variables. (i386bsd_sc_reg_offset): New variable. (i386bsd_init_abi): Initialize TDEP->sc_reg_offset and TDEP->sc_num_regs instead of TDEP->sc_pc_offset and TDEP->sc_sp_offset. (i386fbsd_sc_reg_offset): New variable. (i386fbsdaout_init_abi): Initialize TDEP->sc_reg_offset and TDEP->sc_num_regs. (i386fbsd4_sc_pc_offset, i386fbsd4_sc_sp_offset): Remove variables. (i386fbsd4_sc_reg_offset): New variable. (i3864bsd4_init_abi): Initialize TDEP->sc_reg_offset and TDEP->sc_num_regs instead of TDEP->sc_pc_offset and TDEP->sc_sp_offset. * i386-linux-tdep.c (i386_linux_sc_reg_offset): New variable. (i386_linux_init_abi): Set TDEP->sc_reg_offset and TDEP->sc_num_regs. * i386nbsd-tdep.c (i386nbsd_sc_pc_offset, i386nbsd_sc_sp_offset): Remove variables. (i386nbsd_sc_reg_offset): New variable. (i386nbsd_init_abi): Initialize TDEP->sc_reg_offset and TDEP->sc_num_regs instead of TDEP->sc_pc_offset and TDEP->sc_sp_offset. * i386obsd-tdep.c (i386obsd_sc_pc_offset, i386obsd_sc_sp_offset): Remove variables. (i386obsd_sc_reg_offset): New variable. (i386obsd_init_abi): Initialize TDEP->sc_reg_offset and TDEP->sc_num_regs instead of TDEP->sc_pc_offset and TDEP->sc_sp_offset. * i386bsd-nat.c (_initialize_i386bsd_nat): Adjust for changes in i386bsd-tdep.c, i386nbsd-tdep.c and i386obsd-tdep.c. Add check for frame pointer offset in `struct sigcontext'. --- gdb/i386nbsd-tdep.c | 25 +++++++++++++++++++++---- 1 file changed, 21 insertions(+), 4 deletions(-) (limited to 'gdb/i386nbsd-tdep.c') diff --git a/gdb/i386nbsd-tdep.c b/gdb/i386nbsd-tdep.c index 64b3dc0..601530b 100644 --- a/gdb/i386nbsd-tdep.c +++ b/gdb/i386nbsd-tdep.c @@ -239,8 +239,25 @@ i386nbsd_pc_in_sigtramp (CORE_ADDR pc, char *name) } /* From . */ -int i386nbsd_sc_pc_offset = 44; -int i386nbsd_sc_sp_offset = 56; +int i386nbsd_sc_reg_offset[I386_NUM_GREGS] = +{ + 10 * 4, /* %eax */ + 9 * 4, /* %ecx */ + 8 * 4, /* %edx */ + 7 * 4, /* %ebx */ + 14 * 4, /* %esp */ + 6 * 4, /* %ebp */ + 5 * 4, /* %esi */ + 4 * 4, /* %edi */ + 11 * 4, /* %eip */ + 13 * 4, /* %eflags */ + 12 * 4, /* %cs */ + 15 * 4, /* %ss */ + 3 * 4, /* %ds */ + 2 * 4, /* %es */ + 1 * 4, /* %fs */ + 0 * 4 /* %gs */ +}; static void i386nbsd_init_abi (struct gdbarch_info info, struct gdbarch *gdbarch) @@ -263,8 +280,8 @@ i386nbsd_init_abi (struct gdbarch_info info, struct gdbarch *gdbarch) /* NetBSD has a `struct sigcontext' that's different from the origional 4.3 BSD. */ - tdep->sc_pc_offset = i386nbsd_sc_pc_offset; - tdep->sc_sp_offset = i386nbsd_sc_sp_offset; + tdep->sc_reg_offset = i386nbsd_sc_reg_offset; + tdep->sc_num_regs = I386_NUM_GREGS; } /* NetBSD ELF. */ -- cgit v1.1
