From 1a570b2f5fa09f3130d017b5d6daa6d26593ebd8 Mon Sep 17 00:00:00 2001 From: Michael Snyder Date: Wed, 17 May 2000 17:10:19 +0000 Subject: [PATCH] 2000-05-12 Michael Snyder * gdb.base/break.exp (bp on small function, optimized file): Add a second pass pattern. The behavior differs here between stabs and dwarf for one-line functions. Stabs preserves two line symbols (one before the prologue and one after) with the same line number, but dwarf regards these as duplicates and discards one of them. Therefore the address after the prologue (where the breakpoint is) has no exactly matching line symbol, and GDB reports the breakpoint as if it were in the middle of a line rather than at the beginning. --- gdb/testsuite/ChangeLog | 11 +++++++++++ gdb/testsuite/gdb.base/break.exp | 27 +++++++++++++++++++++++++-- 2 files changed, 36 insertions(+), 2 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index d2248a1ab0..0f7d436aaa 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -5,6 +5,17 @@ Instead, it is permissible for gdb to stop on the line of the call itself. +2000-05-12 Michael Snyder + + * gdb.base/break.exp (bp on small function, optimized file): + Add a second pass pattern.
