From 71dc4d96ed39fadcdccf8c578d49a1afdae0c6ba Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Tue, 21 Sep 2010 21:54:27 +0000 Subject: Move a sign-extend or a zero-extend of a load to the same basic block as the load when the type of the load is not legal, even if truncates are not free. The load is going to be legalized to an extending load anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114488 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Scalar/CodeGenPrepare.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib') diff --git a/lib/Transforms/Scalar/CodeGenPrepare.cpp b/lib/Transforms/Scalar/CodeGenPrepare.cpp index 0e05a26d24..526107c977 100644 --- a/lib/Transforms/Scalar/CodeGenPrepare.cpp +++ b/lib/Transforms/Scalar/CodeGenPrepare.cpp @@ -772,7 +772,8 @@ bool CodeGenPrepare::MoveExtToFormExtLoad(Instruction *I) { // If the load has other users and the truncate is not free, this probably // isn't worthwhile. if (!LI->hasOneUse() && - TLI && !TLI->isTruncateFree(I->getType(), LI->getType())) + TLI && TLI->isTypeLegal(TLI->getValueType(LI->getType())) && + !TLI->isTruncateFree(I->getType(), LI->getType())) return false; // Check whether the target supports casts folded into loads. -- cgit v1.2.3
