*	Revert "Temporarily Revert "Add basic loop fusion pass.""	Eric Christopher	2019-04-17	1	-0/+192
\| \| \| \| \| \| \| \|	The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
*	Temporarily Revert "Add basic loop fusion pass."	Eric Christopher	2019-04-17	1	-192/+0
\| \| \| \| \| \| \| \|	As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
*	[IndVarSimplify] Add AShr exact flags using induction variables ranges.	David Green	2017-07-05	1	-0/+84
\| \| \| \| \| \| \| \| \| \|	This adds exact flags to AShr/LShr flags where we can statically prove it is valid using the range of induction variables. This allows further optimisations to remove extra loads. Differential Revision: https://reviews.llvm.org/D34207 llvm-svn: 307157
*	Fix PR22222	Sanjoy Das	2015-01-15	1	-106/+0
\| \| \| \| \| \| \| \| \| \| \|	The bug was introduced in r225282. r225282 assumed that sub X, Y is the same as add X, -Y. This is not correct if we are going to upgrade the sub to sub nuw. This change fixes the issue by making the optimization ignore sub instructions. Differential Revision: http://reviews.llvm.org/D6979 llvm-svn: 226075

	of operations that provably don't overflow. For example, we can prove %civ.inc below does not sign-overflow. With this change, IndVarSimplify changes %civ.inc to an add nsw. define i32 @foo(i32* %array, i32* %length_ptr, i32 %init) { entry: %length = load i32* %length_ptr, !range !0 %len.sub.1 = sub i32 %length, 1 %upper = icmp slt i32 %init, %len.sub.1 br i1 %upper, label %loop, label %exit loop: %civ = phi i32 [ %init, %entry ], [ %civ.inc, %latch ] %civ.inc = add i32 %civ, 1 %cmp = icmp slt i32 %civ.inc, %length br i1 %cmp, label %latch, label %break latch: store i32 0, i32* %array %check = icmp slt i32 %civ.inc, %len.sub.1 br i1 %check, label %loop, label %break break: ret i32 %civ.inc exit: ret i32 42 } Differential Revision: http://reviews.llvm.org/D6748 llvm-svn: 225282
