From 5beb4d17717570c28e9bf290c64428fda65095b9 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Sat, 2 May 2020 10:56:48 +0200 Subject: [gdb/testsuite] Fix i386-mpx.exp compilation warnings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When running test-case gdb.arch/i386-mpx.exp with gcc-10, we get: ... Running src/gdb/testsuite/gdb.arch/i386-mpx.exp ... gdb compile failed, xgcc: warning: switch '-mmpx' is no longer supported xgcc: warning: switch '-fcheck-pointer-bounds' is no longer supported ... The test-case uses a combination of options, -mmpx and -fcheck-pointer-bounds. The -fcheck-pointer-bounds option requires the -mmpx option: ... $ gcc -fcheck-pointer-bounds ~/hello.c hello.c:1:0: warning: Pointer Checker requires MPX support on this target. \ Use -mmpx options to enable MPX. #include cc1: error: ‘-fcheck-pointer-bounds’ is not supported for this target ... Both options is no longer supported in gcc-9. Fix the warnings by testing if the option combination is supported. Tested on x86_64-linux, with gcc-7.5.0 and gcc-10.0.1. gdb/testsuite/ChangeLog: 2020-05-02 Tom de Vries * lib/gdb.exp (supports_mpx_check_pointer_bounds): New proc. * gdb.arch/i386-mpx-call.exp: Use supports_mpx_check_pointer_bounds. * gdb.arch/i386-mpx-map.exp: Same. * gdb.arch/i386-mpx-sigsegv.exp: Same. * gdb.arch/i386-mpx-simple_segv.exp: Same. * gdb.arch/i386-mpx.exp: Same. --- gdb/testsuite/gdb.arch/i386-mpx-map.exp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gdb/testsuite/gdb.arch/i386-mpx-map.exp') diff --git a/gdb/testsuite/gdb.arch/i386-mpx-map.exp b/gdb/testsuite/gdb.arch/i386-mpx-map.exp index 3cde42f..995aaa1 100644 --- a/gdb/testsuite/gdb.arch/i386-mpx-map.exp +++ b/gdb/testsuite/gdb.arch/i386-mpx-map.exp @@ -23,6 +23,10 @@ if { ![istarget i?86-*-*] && ![istarget x86_64-*-* ] } { standard_testfile +if { ![supports_mpx_check_pointer_bounds] } { + return -1 +} + set comp_flags "-mmpx -fcheck-pointer-bounds -I${srcdir}/../nat/" if { [prepare_for_testing "failed to prepare" ${testfile} ${srcfile} \ -- cgit v1.1
