* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-77/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [CodeGen] Enable tail calls for functions with NonNull attributes.David Green2018-09-261-0/+77
Adding NonNull as attributes to returned pointers has the unfortunate side effect of disabling tail calls. This patch ignores the NonNull attribute when we decide whether to tail merge, in the same way that we ignore the NoAlias attribute, as it has no affect on the call sequence. Differential Revision: https://reviews.llvm.org/D52238 llvm-svn: 343091
