From 2b69325792f7aed5416aa4489dabd197e4c17254 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20Chigot?= Date: Tue, 21 Feb 2023 15:07:58 +0100 Subject: [PATCH] testsuite: prune DOS drive letter in test outputs On DOS systems, absolute paths start with the drive letter. This can trigger failures in the regexp from dump tests, especially for those checking for warnings or errors. They are usually skipping everything before the first ":" as it has to be the file path. | [^:]*: warning: ... In order to avoid modifying many regexps to allow such drive letters, prune them from all the outputs if they are found at the beginning of a line. binutils/ChangeLog: * testsuite/lib/binutils-common.exp (prune_dump_output): New (run_dump_test): Use it. ld/ChangeLog: * testsuite/ld-elf/noinit-sections-2.l: Remove DOS drive letter handler. --- binutils/testsuite/lib/binutils-common.exp | 18 +++++++++++++++++- ld/testsuite/ld-elf/noinit-sections-2.l | 4 ++-- 2 files changed, 19 insertions(+), 3 deletions(-) diff --git a/binutils/testsuite/lib/binutils-common.exp b/binutils/testsuite/lib/binutils-common.exp index ab752417295..530316e54cd 100644 --- a/binutils/testsuite/lib/binutils-common.exp +++ b/binutils/testsuite/lib/binutils-common.exp @@ -687,6 +687,22 @@ if ![string length [info proc prune_warnings]] { } } +# prune_dump_output OUTPUT +# +# Clean up the output from system specific or unwanted characters. +# This allows to simplify the regexp inside dump tests. +proc prune_dump_output { output } { + if [ishost "*-*-mingw*"] { + # Prune DOS drive letter from an absolute path if it appears + # at the beginning of a line. + regsub -all {(^|\n)[[:alpha:]]:(/|\\)} $output "\\1\\2" output + } + + # Prune last end of line. + regsub "\n$" $output "" output + return $output +} + # run_dump_test FILE (optional:) EXTRA_OPTIONS # # Assemble a .s file, then run some utility on it and check the output. @@ -1450,7 +1466,7 @@ proc run_dump_test { name {extra_options {}} } { } } - regsub "\n$" $comp_output "" comp_output + set comp_output [prune_dump_output $comp_output] if { $cmdret != 0 || $comp_output != "" || $want_out(source) != "" } { set exitstat "succeeded" if { $cmdret != 0 } { set exitstat "failed" } diff --git a/ld/testsuite/ld-elf/noinit-sections-2.l b/ld/testsuite/ld-elf/noinit-sections-2.l index 8ed2716c549..0784c9e3e12 100644 --- a/ld/testsuite/ld-elf/noinit-sections-2.l +++ b/ld/testsuite/ld-elf/noinit-sections-2.l @@ -1,5 +1,5 @@ #... -(|.:)[^:]*: warning: orphan section `.noinit.var_noinit' from \S+ being placed in section `.noinit.var_noinit' +[^:]*: warning: orphan section `.noinit.var_noinit' from \S+ being placed in section `.noinit.var_noinit' #... -(|.:)[^:]*: warning: orphan section `.gnu.linkonce.n.var_noinit2' from \S+ being placed in section `.gnu.linkonce.n.var_noinit2' +[^:]*: warning: orphan section `.gnu.linkonce.n.var_noinit2' from \S+ being placed in section `.gnu.linkonce.n.var_noinit2' #pass -- 2.30.2
