Author: mgorny Date: Wed Dec 19 09:25:59 2018 New Revision: 349650 URL: http://llvm.org/viewvc/llvm-project?rev=349650&view=rev Log: [Driver] [NetBSD] Add -D_REENTRANT when using sanitizers
NetBSD intends to support only reentrant interfaces in interceptors. When -lpthread is used without _REENTRANT defined, things are not guaranteed to work. This is especially important for <stdio.h> and sanitization of interfaces around FILE. Some APIs have alternative modes depending on the _REENTRANT definition, and NetBSD intends to support sanitization of the _REENTRANT ones.
