From cc86d1cb9510dbba32bf19e5d2699f2972efbc03 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Thu, 18 Dec 2014 20:47:28 +0800 Subject: Refactor gdbarch method print_float_info This patch is to change print_float_info gdbarch method for the following two reasons, 1. we want to add a default implementation of print_float_info to dump the float pointer registers. It can be reused by backend to print something more than float point registers. 2. we want to simplify the caller of print_float_info, infcmd.c:print_float_info. gdb: 2014-12-18 Yao Qi * gdbarch.sh (print_float_info): Change its type from 'M' to 'm'. * gdbarch.c: Re-generated. * gdbarch.h: Likewise. * infcmd.c (default_print_float_info): New function. (print_float_info): Removed. Move code to default_print_float_info. (float_info): Adjust to call gdbarch_print_float_info. * inferior.h (default_print_float_info): Declare it. --- gdb/infcmd.c | 44 +++++++++++++++++++++----------------------- 1 file changed, 21 insertions(+), 23 deletions(-) (limited to 'gdb/infcmd.c') diff --git a/gdb/infcmd.c b/gdb/infcmd.c index 9d0a527..9b65f1a 100644 --- a/gdb/infcmd.c +++ b/gdb/infcmd.c @@ -2867,43 +2867,41 @@ interrupt_command (char *args, int from_tty) } } -static void -print_float_info (struct ui_file *file, - struct frame_info *frame, const char *args) +/* See inferior.h. */ + +void +default_print_float_info (struct gdbarch *gdbarch, struct ui_file *file, + struct frame_info *frame, const char *args) { - struct gdbarch *gdbarch = get_frame_arch (frame); + int regnum; + int printed_something = 0; - if (gdbarch_print_float_info_p (gdbarch)) - gdbarch_print_float_info (gdbarch, file, frame, args); - else + for (regnum = 0; + regnum < gdbarch_num_regs (gdbarch) + + gdbarch_num_pseudo_regs (gdbarch); + regnum++) { - int regnum; - int printed_something = 0; - - for (regnum = 0; - regnum < gdbarch_num_regs (gdbarch) - + gdbarch_num_pseudo_regs (gdbarch); - regnum++) + if (gdbarch_register_reggroup_p (gdbarch, regnum, float_reggroup)) { - if (gdbarch_register_reggroup_p (gdbarch, regnum, float_reggroup)) - { - printed_something = 1; - gdbarch_print_registers_info (gdbarch, file, frame, regnum, 1); - } + printed_something = 1; + gdbarch_print_registers_info (gdbarch, file, frame, regnum, 1); } - if (!printed_something) - fprintf_filtered (file, "No floating-point info " - "available for this processor.\n"); } + if (!printed_something) + fprintf_filtered (file, "No floating-point info " + "available for this processor.\n"); } static void float_info (char *args, int from_tty) { + struct frame_info *frame; + if (!target_has_registers) error (_("The program has no registers now.")); - print_float_info (gdb_stdout, get_selected_frame (NULL), args); + frame = get_selected_frame (NULL); + gdbarch_print_float_info (get_frame_arch (frame), gdb_stdout, frame, args); } static void -- cgit v1.1
