<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-lld-elf Author: David Spickett (DavidSpickett) <details> <summary>Changes</summary> This test has been reported to fail on a release bot, but nothing in the content of the test on the release branch should cause this problem: ld.lld: error: cannot open output file /home/buildbot/as-worker-92/clang-with-thin-lto-ubuntu-rel/build/stage1/tools/lld/test/ELF/Output/aarch64-build-attributes.s.tmp: Is a directory The reason this is happening is that if the same builder happened to run the extended version of this test, from a build of main, it would create a directory with that name. The test on main stashes the temporary files in that directory. $ tree tools/lld/test/ tools/lld/test/ ├── CMakeFiles ├── ELF │ └── Output │ ├── aarch64-build-attributes.s.tmp │ │ ├── pauth-bti-gcs.s │ │ └── pauth-bti-pac.s │ ├── aarch64-build-attributes.s.tmp.merged.o │ ├── aarch64-build-attributes.s.tmp1.o │ ├── aarch64-build-attributes.s.tmp2.o │ └── aarch64-build-attributes.s.tmp3.o ├── Unit │ └── lit.site.cfg.py ├── cmake_install.cmake └── lit.site.cfg.py If you then had a 21.x build run, it would find that pre-existing directory and try to write to it as if it were a file. ld.lld: error: cannot open output file /home/david.spickett/build-llvm-aarch64/tools/lld/test/ELF/Output/aarch64-build-attributes.s.tmp: Is a directory To fix this, remove the file or directory names we're going to use, before the test starts. (if this were main I'd put all the files in one direcory, but in the interest of keeping release changes small I'm just adding the rm line) --- Full diff: https://github.com/llvm/llvm-project/pull/164384.diff 1 Files Affected: - (modified) lld/test/ELF/aarch64-build-attributes.s (+1) ``````````diff diff --git a/lld/test/ELF/aarch64-build-attributes.s b/lld/test/ELF/aarch64-build-attributes.s index 24e15f94e3d4a..815aed32f2aaa 100644 --- a/lld/test/ELF/aarch64-build-attributes.s +++ b/lld/test/ELF/aarch64-build-attributes.s @@ -1,4 +1,5 @@ // REQUIRES: aarch64 +// RUN: rm -rf %t %t.o %t.so %t2.o // RUN: llvm-mc -triple=aarch64 %s -filetype=obj -o %t.o // RUN: ld.lld %t.o --shared -o %t.so // RUN: llvm-readelf --sections %t.so | FileCheck %s `````````` </details> https://github.com/llvm/llvm-project/pull/164384 _______________________________________________ llvm-branch-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
