From 8278fcaef405f3d7a1e2aae4ad9f2a9d92209618 Mon Sep 17 00:00:00 2001 From: Sriraman Tallam Date: Fri, 8 Jan 2021 22:33:53 -0800 Subject: [PATCH] Revert "This adds a new test checking llvm-symbolizer with an object built with basic block sections." This reverts commit 1816de08232673e97ec41287ad3f6494bceaec43. This breaks on ppc64 and windows although x86-registered-target is mentioned. I will re-commit after fixing. --- .../DebugInfo/llvm-symbolizer-bbsections-test.s | 594 --------------------- 1 file changed, 594 deletions(-) delete mode 100644 llvm/test/DebugInfo/llvm-symbolizer-bbsections-test.s diff --git a/llvm/test/DebugInfo/llvm-symbolizer-bbsections-test.s b/llvm/test/DebugInfo/llvm-symbolizer-bbsections-test.s deleted file mode 100644 index 822ce26..0000000 --- a/llvm/test/DebugInfo/llvm-symbolizer-bbsections-test.s +++ /dev/null @@ -1,594 +0,0 @@ -# REQUIRES: x86-registered-target -# RUN: clang -c %s -o %t -# RUN: llvm-symbolizer --obj=%t 0x30 0x20 0x6c 0xf | FileCheck %s -
