As `\s` is a GNU extension, it is not supported by the system grep on AIX and thus fails in the [buildbot](https://lab.llvm.org/buildbot/#/builders/64/builds/6835): ``` ******************** TEST 'Clang :: Frontend/rewrite-includes-bom.c' FAILED ******************** Exit Code: 1 Command Output (stdout): -- # RUN: at line 1 cat /home/llvm/llvm-external-buildbots/workers/aix-ppc64/clang-ppc64-aix/llvm-project/clang/test/Frontend/Inputs/rewrite-includes-bom.h | od -t x1 | grep -q 'ef\s*bb\s*bf' # executed command: cat /home/llvm/llvm-external-buildbots/workers/aix-ppc64/clang-ppc64-aix/llvm-project/clang/test/Frontend/Inputs/rewrite-includes-bom.h # executed command: od -t x1 # executed command: grep -q 'ef\s*bb\s*bf' # note: command had no output on stdout or stderr # error: command failed with exit status: 1 -- ******************** ``` This change replaces `\s` with the POSIX-compliant `[[:space::]]` so the test is supported on AIX. >From d988aa08aea7f6445d230fe80c378a892903874a Mon Sep 17 00:00:00 2001 From: Alison Zhang <[email protected]> Date: Wed, 14 Jan 2026 17:02:56 -0500 Subject: [PATCH] Fix rewrite-includes-bom.c to use posix grep regex --- clang/test/Frontend/rewrite-includes-bom.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/clang/test/Frontend/rewrite-includes-bom.c b/clang/test/Frontend/rewrite-includes-bom.c index 27bf470ba1fd1..0c60ee66c8e73 100644 --- a/clang/test/Frontend/rewrite-includes-bom.c +++ b/clang/test/Frontend/rewrite-includes-bom.c @@ -1,6 +1,6 @@ -// RUN: cat %S/Inputs/rewrite-includes-bom.h | od -t x1 | grep -q 'ef\s*bb\s*bf' +// RUN: cat %S/Inputs/rewrite-includes-bom.h | od -t x1 | grep -q 'ef[[:space:]]*bb[[:space:]]*bf' // RUN: %clang_cc1 -E -frewrite-includes -I %S/Inputs %s -o %t.c -// RUN: cat %t.c | od -t x1 | not grep -q 'ef\s*bb\s*bf' +// RUN: cat %t.c | od -t x1 | not grep -q 'ef[[:space:]]*bb[[:space:]]*bf' // RUN: %clang_cc1 -fsyntax-only -verify %t.c // expected-no-diagnostics // UNSUPPORTED: system-windows _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
