>From db9972322071ceb5206605186ab37aaf08bdf11b Mon Sep 17 00:00:00 2001 From: Alison Zhang <[email protected]> Date: Wed, 14 Jan 2026 17:44:30 -0500 Subject: [PATCH] [Clang] Fix rewrite-includes-bom.c to use POSIX-compliant regex (#176043) 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.
