URL: https://github.com/llvm/llvm-project/commit/4c6350f4e393c1782fd479798485b55063aa90fc DIFF: https://github.com/llvm/llvm-project/commit/4c6350f4e393c1782fd479798485b55063aa90fc.diff LOG: [compiler-rt] [test] Handle missing ld.gold gracefully Fix the is_binutils_lto_supported() function to handle missing executables gracefully. Currently, the function does not catch exceptions from subprocess.Popen() and therefore causes lit to crash if config.gold_executable does not specify a valid executable: ``` lit: /usr/lib/python3.11/site-packages/lit/TestingConfig.py:136: fatal: unable to parse config file '/tmp/portage/sys-libs/compiler-rt- 15.0.0/work/compiler-rt/test/lit.common.cfg.py', traceback: Traceback (most recent call last): File "/usr/lib/python3.11/site-packages/lit/TestingConfig.py", line 125, in load_from_path exec(compile(data, path, 'exec'), cfg_globals, None) File "/tmp/portage/sys-libs/compiler-rt-15.0.0/work/compiler-rt/test/lit.common.cfg.py", line 561, in <module> if is_binutils_lto_supported(): ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/tmp/portage/sys-libs/compiler-rt-15.0.0/work/compiler-rt/test/lit.common.cfg.py", line 543, in is_binutils_lto_supported ld_cmd = subprocess.Popen([exe, '--help'], stdout=subprocess.PIPE, env={'LANG': 'C'}) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/subprocess.py", line 1022, in __init__ self._execute_child(args, executable, preexec_fn, close_fds, File "/usr/lib/python3.11/subprocess.py", line 1899, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'GOLD_EXECUTABLE-NOTFOUND' ``` Differential Revision: https://reviews.llvm.org/D133358 (cherry picked from commit ea953b9d9a65c202985a79f1f95da115829baef6) Added: Modified: compiler-rt/test/lit.common.cfg.py Removed: ################################################################################ diff --git a/compiler-rt/test/lit.common.cfg.py b/compiler-rt/test/lit.common.cfg.py index c5a8420da14ff..3dd258283e5ce 100644 --- a/compiler-rt/test/lit.common.cfg.py +++ b/compiler-rt/test/lit.common.cfg.py @@ -540,9 +540,12 @@ def is_binutils_lto_supported(): # We require both ld.bfd and ld.gold exist and support plugins.
