From d974236f808582b586d34119aba2caa985d173b9 Mon Sep 17 00:00:00 2001 From: John Gilmore Date: Thu, 17 Sep 1992 10:58:53 +0000 Subject: [PATCH] * utils.c (prompt_for_continue): Reinitialize more-counts before printing anything, and again afterward. Fix comments. (vfprintf_filtered): Eliminate static buffer; use auto buffer, or alloca() if needed. * rs6000-xdep.c: Use correct conditional (IBM6000_TARGET) to detect native versus cross-host. --- gdb/ChangeLog | 10 ++++++++++ gdb/rs6000-xdep.c | 6 +++--- gdb/utils.c | 38 ++++++++++++++++++++------------------ 3 files changed, 33 insertions(+), 21 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5d17d86..b4a1b81 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,13 @@ +Thu Sep 17 03:49:59 1992 John Gilmore (gnu@cygnus.com) + + * utils.c (prompt_for_continue): Reinitialize more-counts + before printing anything, and again afterward.
