* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-23/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [PGO] Fix PGO use ICE when there are unreachable BBsRong Xu2016-12-021-0/+23
For -O0 there might be unreachable BBs, which breaks the assumption that all the BBs have an auxiliary data structure. In this patch, we add another interface called findBBInfo() so that a nullptr can be returned for the unreachable BBs (and the callers can ignore those BBs). This fixes the bug reported https://llvm.org/bugs/show_bug.cgi?id=31209 Differential Revision: https://reviews.llvm.org/D27280 llvm-svn: 288528
