(special_address): Now inline. (bp_holder): Put raising of buserror there, rename to: (raise_buserror). (BUSERROR): Now yields a value. Changed all users. (wbat_big): Delete. (wlat_fast, wwat_fast, wbat_fast): New functions. (rlat_fast, rwat_fast, rbat_fast): Likewise. (RWAT, RLAT, RBAT, WWAT, WLAT, WBAT): Use new functions. (do_rdat, do_wdat): Likewise. Take maskl argument instead of little_endian one. Changed caller macros. (swap, swap16): Use w[rw]lat_big / w[rw]lat_little directly. (strswaplen, strnswap): New functions. (trap): Use them to fix up endian mismatches; disable SYS_execve and SYS_execv; fix double address translation for SYS_pipe and SYS_stat. (sym_write, sym_read): Add endianness translation. (sym_store_register, sym_fetch_register): Add maskl local variable. (sim_open): Set endianw and endianb. gdb: * sh-tdep.c (sh_dsp_reg_names, sh3_dsp_reg_names): New arrays. (sh_processor_type_table): Add entries for bfd_mach_sh_dsp and bfd_mach_sh3_dsp. (sh_show_regs): Floating point registers are called fr0-fr15. For sh4, display fpul, fpscr and fr0-fr15 / dr0-dr14 as appropriate. Handle sh-dsp and sh3-dsp. config/sh/tm-sh.h (REGISTER_VIRTUAL_TYPE): sh-dsp / sh3-dsp don't have floating point registers. (DSR_REGNUM, A0G_REGNUM, A0_REGNUM, A1G_REGNUM, A1_REGNUM): Define. (M0_REGNUM, M1_REGNUM, X0_REGNUM, X1_REGNUM, Y0_REGNUM): Likewise. (Y1_REGNUM, MOD_REGNUM, RS_REGNUM, RE_REGNUM, R0B_REGNUM): Likewise.	27 years ago
