From dae43a260cf59bac6c92d436c11bec0cb8ce2d8b Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 18 Jun 2009 16:54:06 +0000 Subject: Remove the code from IVUsers that attempted to handle casted induction variables in cases where the cast isn't foldable. It ended up being a pessimization in many cases. This could be fixed, but it would require a bunch of complicated code in IVUsers' clients. The advantages of this approach aren't visible enough to justify it at this time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73706 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/IndVarSimplify/masked-iv.ll | 4 +++- test/Transforms/IndVarSimplify/shrunk-constant.ll | 3 ++- 2 files changed, 5 insertions(+), 2 deletions(-) (limited to 'test/Transforms') diff --git a/test/Transforms/IndVarSimplify/masked-iv.ll b/test/Transforms/IndVarSimplify/masked-iv.ll index c7583c9..f77b935 100644 --- a/test/Transforms/IndVarSimplify/masked-iv.ll +++ b/test/Transforms/IndVarSimplify/masked-iv.ll @@ -1,4 +1,6 @@ -; RUN: llvm-as < %s | opt -indvars | llvm-dis | grep trunc | count 1 +; RUN: llvm-as < %s | opt -indvars | llvm-dis > %t +; RUN: not grep trunc %t +; RUN: grep and %t | count 1 ; Indvars should do the IV arithmetic in the canonical IV type (i64), ; and only use one truncation. diff --git a/test/Transforms/IndVarSimplify/shrunk-constant.ll b/test/Transforms/IndVarSimplify/shrunk-constant.ll index f1caf14..0b2ecaf 100644 --- a/test/Transforms/IndVarSimplify/shrunk-constant.ll +++ b/test/Transforms/IndVarSimplify/shrunk-constant.ll @@ -1,4 +1,5 @@ -; RUN: llvm-as < %s | opt -iv-users -analyze -disable-output | grep store +; RUN: llvm-as < %s | opt -scalar-evolution -analyze -disable-output \ +; RUN: | grep {\\--> (zext i4 {-7,+,-8} to i32)} define fastcc void @foo() nounwind { entry: -- cgit v1.1
