From a38d2a54bea9fc3080e12cf0381c8ae32684a8e3 Mon Sep 17 00:00:00 2001 From: Elena Zannoni Date: Fri, 15 Dec 2000 20:54:24 +0000 Subject: [PATCH] 2000-12-15 Elena Zannoni * sh-tdep.c (sh_do_pseudo_register): Indent properly. Call do_dr_register_info() only for DR registers. (sh_sh4_register_name): Add comments with numbers. (_initialize_sh_tdep): Move assignment to disassemble printing function from here... (sh_gdbarch_init):...to here. Move some more general settings to before the architecture is recognized. --- gdb/ChangeLog | 11 +++++++++++ gdb/sh-tdep.c | 42 +++++++++++++++++++++++++++--------------- 2 files changed, 38 insertions(+), 15 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index f3b7940486f..4724fb5b406 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,13 @@ +2000-12-15 Elena Zannoni + + * sh-tdep.c (sh_do_pseudo_register): Indent properly.
