From 058e2757b9bf44968af4cc93cd8334e3dba6f362 Mon Sep 17 00:00:00 2001 From: Tomas Vondra Date: Sat, 19 Jan 2019 20:42:44 +0100 Subject: [PATCH] Revert "Add valgrind suppressions for wcsrtombs optimizations" This reverts commit 71b2951ccc433a6dd799efedff9f5927c32440f6. Per discussion, it's not desirable to add valgrind suppressions for outside our own code base (e.g. glibc in this case), especially when the suppressions may be platform-specific. There are better ways to deal with that, e.g. by providing local suppressions.
