From 7f5439945b1f07535ea667ec31a82a9d9a2a8666 Mon Sep 17 00:00:00 2001 From: Paul Kirth Date: Mon, 23 May 2022 18:22:40 +0000 Subject: [PATCH] [compiler-rt][test] Fix flake in symbolize_stack test Addresses tests flakes described in https://github.com/llvm/llvm-project/issues/55460 The test being updated can fail in FileCheck to match when given long enough stack traces. This can be problematic when file system paths become long enough to cause the majority of the long function name to become truncated. We found in our CI that the truncated output would often fail to match, thereby causing the test to fail when it should not. Here we change the test to match on sybolizer output that should be more reliable than matching inside the long function name.
