From e92f0cfe349ab0ba9b8bd698ef68e78f9382f63e Mon Sep 17 00:00:00 2001 From: Mandeep Singh Grang Date: Fri, 6 Apr 2018 18:08:42 +0000 Subject: [CodeGen] Change std::sort to llvm::sort in response to r327219 Summary: r327219 added wrappers to std::sort which randomly shuffle the container before sorting. This will help in uncovering non-determinism caused due to undefined sorting order of objects having the same key. To make use of that infrastructure we need to invoke llvm::sort instead of std::sort. Note: This patch is one of a series of patches to replace *all* std::sort to llvm::sort. Refer the comments section in D44363 for a list of all the required patches.
