From: Mark Kettenis Date: Sun, 10 Aug 2003 18:06:05 +0000 (+0000) Subject: * i386-tdep.c (i386_register_to_value): Use get_frame_register X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f837910f91f680e0058a04a19442986c098cc30a;p=binutils-gdb.git * i386-tdep.c (i386_register_to_value): Use get_frame_register instead of frame_read_register. (i386_fetch_pointer_argument): Use get_frame_register_unsigned instead of frame_read_register. Use I386_ESP_REGNUM instead of SP_REGNUM. (i386_frame_prev_register): Use frame_unwind_register_unsigned instead of frame_unwind_unsigned_register. Use I386_EFLAGS_REGISTER instead of PS_REGNUM. (i386_get_longjmp_target): Use regcache_read_unsigned_register instead of read_register. Use builtin_type_void_data_ptr instead of builtin_type_void_func_ptr when extracting the address of the jmp_buf. (i386_extract_return_value, i386_store_return_value, i386_pseudo_register_read, i386_pseudo_register_write): Use register_size instead REGISTER_RAW_SIZE.
