From a8454a7c5a2254b249b1bac34e7cef1438bca9f2 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 21 Aug 2014 11:36:59 +0100 Subject: Remove useless gcore command detection Checking whether the gcore command is included in the GDB build as proxy for checking whether core dumping is supported by the target is useless, as gcore.o has been in COMMON_OBS since git 9b4eba8e: 2009-10-26 Michael Snyder Hui Zhu * Makefile.in (SFILES): Add gcore.c. (COMMON_OBS): Add gcore.o. * config/alpha/alpha-linux.mh (NATDEPFILES): Delete gcore.o. * config/alpha/fbsd.mh (NATDEPFILES): Ditto. ... IOW, the command is always included in the build. Instead, nowadays, tests bail out if actually trying to generate a core fails with an indication the target doesn't support it. See gdb_gcore_cmd and callers. Tested on x86_64 Fedora 20. gdb/testsuite/ChangeLog: * gdb.base/gcore-buffer-overflow.exp: Remove "help gcore" test. * gdb.base/gcore-relro-pie.exp: Likewise. * gdb.base/gcore-relro.exp: Likewise. * gdb.base/gcore.exp: Likewise. * gdb.base/print-symbol-loading.exp: Likewise. * gdb.threads/gcore-thread.exp: Likewise. * lib/gdb.exp (gdb_gcore_cmd): Don't expect "Undefined command". --- gdb/testsuite/ChangeLog | 10 ++++++++++ gdb/testsuite/gdb.base/gcore-buffer-overflow.exp | 12 ------------ gdb/testsuite/gdb.base/gcore-relro-pie.exp | 13 ------------- gdb/testsuite/gdb.base/gcore-relro.exp | 13 ------------- gdb/testsuite/gdb.base/gcore.exp | 12 ------------ gdb/testsuite/gdb.base/print-symbol-loading.exp | 13 ------------- gdb/testsuite/gdb.threads/gcore-thread.exp | 11 ----------- gdb/testsuite/lib/gdb.exp | 6 ------ 8 files changed, 10 insertions(+), 80 deletions(-) (limited to 'gdb') diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index a9205d1..31c64ff 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,13 @@ +2014-08-21 Pedro Alves + + * gdb.base/gcore-buffer-overflow.exp: Remove "help gcore" test. + * gdb.base/gcore-relro-pie.exp: Likewise. + * gdb.base/gcore-relro.exp: Likewise. + * gdb.base/gcore.exp: Likewise. + * gdb.base/print-symbol-loading.exp: Likewise. + * gdb.threads/gcore-thread.exp: Likewise. + * lib/gdb.exp (gdb_gcore_cmd): Don't expect "Undefined command". + 2014-08-20 Pedro Alves Jan Kratochvil diff --git a/gdb/testsuite/gdb.base/gcore-buffer-overflow.exp b/gdb/testsuite/gdb.base/gcore-buffer-overflow.exp index 1951301..f7a69ba 100644 --- a/gdb/testsuite/gdb.base/gcore-buffer-overflow.exp +++ b/gdb/testsuite/gdb.base/gcore-buffer-overflow.exp @@ -31,18 +31,6 @@ if { [gdb_compile "${srcdir}/${subdir}/${srcfile}" "${binfile}" executable {deb clean_restart ${binfile} -# Does this gdb support gcore? -gdb_test_multiple "help gcore" "help gcore" { - -re "Undefined command: .gcore.*$gdb_prompt $" { - # gcore command not supported -- nothing to test here. - unsupported "gdb does not support gcore on this target" - return -1 - } - -re "Save a core file .*$gdb_prompt $" { - pass "help gcore" - } -} - gdb_test_no_output "set args ${pattern}" \ "Set buffer exceeding arguments" diff --git a/gdb/testsuite/gdb.base/gcore-relro-pie.exp b/gdb/testsuite/gdb.base/gcore-relro-pie.exp index e0c0de0..468e846 100644 --- a/gdb/testsuite/gdb.base/gcore-relro-pie.exp +++ b/gdb/testsuite/gdb.base/gcore-relro-pie.exp @@ -39,19 +39,6 @@ file attributes ${stripped_binfile} -permissions $perm clean_restart ${stripped_binfile} -# Does this gdb support gcore? -set test "help gcore" -gdb_test_multiple $test $test { - -re "Undefined command: .gcore.*\r\n$gdb_prompt $" { - # gcore command not supported -- nothing to test here. - unsupported "gdb does not support gcore on this target" - return -1 - } - -re "Save a core file .*\r\n$gdb_prompt $" { - pass $test - } -} - # The binary is stripped of debug info, but not minsyms. if ![runto break_here] { fail "Can't run to break_here" diff --git a/gdb/testsuite/gdb.base/gcore-relro.exp b/gdb/testsuite/gdb.base/gcore-relro.exp index 8278de2..d5f4b69 100644 --- a/gdb/testsuite/gdb.base/gcore-relro.exp +++ b/gdb/testsuite/gdb.base/gcore-relro.exp @@ -38,19 +38,6 @@ set objfile [standard_output_file ${testfile}.o] clean_restart ${binfile} gdb_load_shlibs ${binfile_lib} -# Does this gdb support gcore? -set test "help gcore" -gdb_test_multiple $test $test { - -re "Undefined command: .gcore.*\r\n$gdb_prompt $" { - # gcore command not supported -- nothing to test here. - unsupported "gdb does not support gcore on this target" - return -1 - } - -re "Save a core file .*\r\n$gdb_prompt $" { - pass $test - } -} - if ![runto lib] { return -1 } diff --git a/gdb/testsuite/gdb.base/gcore.exp b/gdb/testsuite/gdb.base/gcore.exp index c28a9b3..15de624 100644 --- a/gdb/testsuite/gdb.base/gcore.exp +++ b/gdb/testsuite/gdb.base/gcore.exp @@ -24,18 +24,6 @@ if {[prepare_for_testing $testfile.exp $testfile $srcfile debug]} { return -1 } -# Does this gdb support gcore? -gdb_test_multiple "help gcore" "help gcore" { - -re "Undefined command: .gcore.*$gdb_prompt $" { - # gcore command not supported -- nothing to test here. - unsupported "gdb does not support gcore on this target" - return -1 - } - -re "Save a core file .*$gdb_prompt $" { - pass "help gcore" - } -} - if { !
