From e334ae4a0cd5ee5e8a6a8a62047d4d89207238a1 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 22 Aug 2024 14:13:49 -0300 Subject: perf python: Allow checking for the existence of warning options in clang commit b81162302001f41157f6e93654aaccc30e817e2a upstream. We'll need to check if an warning option introduced in clang 19 is available on the clang version being used, so cover the error message emitted when testing for a -W option.
