From 5eb39cde1e2487ba5ec1802dc5e58a77e700d99e Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Thu, 16 Mar 2023 23:47:05 +0100 Subject: kcsan: avoid passing -g for test Nathan reported that when building with GNU as and a version of clang that defaults to DWARF5, the assembler will complain with: Error: non-constant .uleb128 is not supported This is because `-g` defaults to the compiler debug info default. If the assembler does not support some of the directives used, the above errors occur. To fix, remove the explicit passing of `-g`. All the test wants is that stack traces print valid function names, and debug info is not required for that. (I currently cannot recall why I added the explicit `-g`.)
