From Michal Ludvig <mludvig@suse.cz>:
* 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'.
