From 1678f8f876e10a805f7ee7b436fa3ae2e68d1fc7 Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Sat, 2 Nov 2002 15:13:34 +0000 Subject: [PATCH] 2002-11-02 Andrew Cagney * reggroups.h, reggroups.c: New files. * regcache.c: Include "reggroups.h". (enum regcache_dump_what): Add `regcache_dump_groups'. (regcache_dump): Contract size of the "Type" column. When specified, dump the register's groups. (maintenance_print_register_groups): New function. (_initialize_regcache): Add command `maint print register-groups'. * Makefile.in (COMMON_OBS): Add reggroups.o (SFILES): Add reggroups.c. (reggroups_h): Define. (regcache.o, gdbarch.o): Update dependencies. (reggroups.o): Specify dependencies. * gdbarch.sh (register_reggroup_p): Add pure multi-arch method. Add opaque declaration for `struct reggroup' in generated .h file. Include "reggroups.h" in generated .c file. gdbarch.h, gdbarch.c: Re-generate. --- gdb/ChangeLog | 19 ++++ gdb/Makefile.in | 14 +-- gdb/gdbarch.c | 30 +++++++ gdb/gdbarch.h | 7 ++ gdb/gdbarch.sh | 4 + gdb/regcache.c | 83 +++++++++++++----- gdb/reggroups.c | 268 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ gdb/reggroups.h | 61 +++++++++++++ 8 files changed, 459 insertions(+), 27 deletions(-) create mode 100644 gdb/reggroups.c create mode 100644 gdb/reggroups.h diff --git a/gdb/ChangeLog b/gdb/ChangeLog index effdb1f6d2..61f6723b5e 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,24 @@ 2002-11-02 Andrew Cagney + * reggroups.h, reggroups.c: New files. + * regcache.c: Include "reggroups.h". + (enum regcache_dump_what): Add `regcache_dump_groups'. + (regcache_dump): Contract size of the "Type" column.
