From 364ca42e71dfdce3f34e97ef028f7e3d5b5d880e Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Fri, 9 Dec 2016 09:51:20 +0000 Subject: [PATCH] Compile gdb.perf/skip-prologue.c with and without debug info gdb.perf/skip-prologue.exp is intended to measure the performance of skipping prologue with prologue analysis by setting breakpoints. However, if program is compiled with debug info, GDB is smart to skip prologue by line table from debug info, so prologue analysis is not exercised at all. This patch adds a parameter COMPILE to specify compiling with debug information, otherwise, it is compiled without debug information. gdb/testsuite: 2016-12-09 Yao Qi * gdb.perf/skip-prologue.exp: Add parameter COMPILE. --- gdb/testsuite/ChangeLog | 4 ++++ gdb/testsuite/gdb.perf/skip-prologue.exp | 9 ++++++++- 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index e63f2b7..d905df3 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,7 @@ +2016-12-09 Yao Qi + + * gdb.perf/skip-prologue.exp: Add parameter COMPILE. + 2016-12-02 Luis Machado * gdb.base/maint.exp: Use gdb_test instead of gdb_test_multiple when diff --git a/gdb/testsuite/gdb.perf/skip-prologue.exp b/gdb/testsuite/gdb.perf/skip-prologue.exp index 2c4aad4..f31f697 100644 --- a/gdb/testsuite/gdb.perf/skip-prologue.exp +++ b/gdb/testsuite/gdb.perf/skip-prologue.exp @@ -37,7 +37,14 @@ if ![info exists SKIP_PROLOGUE_COUNT] { PerfTest::assemble { global srcdir subdir srcfile binfile - if { [gdb_compile "$srcdir/$subdir/$srcfile" ${binfile} executable {debug}] != "" } { + if [info exists COMPILE] { + set opts {debug} + } else { + set opts {nodebug} + } + + if { [gdb_compile "$srcdir/$subdir/$srcfile" ${binfile} executable $opts] != "" } { + untested "failed to compile" return -1 } -- 2.7.4
