From d4d38844faaff1576b021558d0835dedbd415e8d Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Thu, 1 Feb 2018 14:50:23 +0000 Subject: [PATCH] Fix gdb.base/attach.exp fails when gdb is configured --with-sysroot=/ I see some test fails in gdb.base/attach.exp when gdb is configured --with-sysroot=/. FAIL: gdb.base/attach.exp: attach2, with no file FAIL: gdb.base/attach.exp: load file manually, after attach2 (re-read) (got interactive prompt) FAIL: gdb.base/attach.exp: attach when process' a.out not in cwd If gdb is configured this way, sysroot is "/" in default, and if binfile is a absolute path, the regexp pattern $sysroot$escapedbinfile is incorrect. There are different ways to fix it, but I don't want to complicate the test, so I choose this naive way. gdb/testsuite: 2018-02-01 Yao Qi * gdb.base/attach.exp (do_attach_tests): Set sysroot to "\[^\r\n\]*". --- gdb/testsuite/ChangeLog | 5 +++++ gdb/testsuite/gdb.base/attach.exp | 15 ++++++--------- 2 files changed, 11 insertions(+), 9 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 00c01fde24e..ad6c04a0715 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,8 @@ +2018-02-01 Yao Qi + + * gdb.base/attach.exp (do_attach_tests): Set sysroot to + "\[^\r\n\]*". + 2018-01-31 Nikola Prica * gdb.arch/powerpc-prologue-frame.s: New file. diff --git a/gdb/testsuite/gdb.base/attach.exp b/gdb/testsuite/gdb.base/attach.exp index d315c2792e3..efec49e3858 100644 --- a/gdb/testsuite/gdb.base/attach.exp +++ b/gdb/testsuite/gdb.base/attach.exp @@ -57,15 +57,12 @@ proc do_attach_tests {} { # Figure out a regular expression that will match the sysroot, # noting that the default sysroot is "target:", and also noting # that GDB will strip "target:" from the start of filenames when - # operating on the local filesystem - set sysroot "" - set test "show sysroot" - gdb_test_multiple $test $test { - -re "The current system root is \"(.*)\"\..*${gdb_prompt} $" { - set sysroot $expect_out(1,string) - } - } - regsub "^target:" "$sysroot" "(target:)?" sysroot + # operating on the local filesystem.
