From 108423a94afddc61983312ad1025cc55efd9351e Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 31 Jan 2012 04:42:22 +0000 Subject: Change ConstantArray::get to form a ConstantDataArray when possible, kicking in the big win of ConstantDataArray. As part of this, change the implementation of GetConstantStringInfo in ValueTracking to work with ConstantDataArray (and not ConstantArray) making it dramatically, amazingly, more efficient in the process and renaming it to getConstantStringInfo. This keeps around a GetConstantStringInfo entrypoint that (grossly) forwards to getConstantStringInfo and constructs the std::string required, but existing clients should move over to getConstantStringInfo instead. llvm-svn: 149351 --- llvm/lib/Analysis/ConstantFolding.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'llvm/lib/Analysis/ConstantFolding.cpp') diff --git a/llvm/lib/Analysis/ConstantFolding.cpp b/llvm/lib/Analysis/ConstantFolding.cpp index 121e334c4cc..48e75a1d5d7 100644 --- a/llvm/lib/Analysis/ConstantFolding.cpp +++ b/llvm/lib/Analysis/ConstantFolding.cpp @@ -476,9 +476,9 @@ Constant *llvm::ConstantFoldLoadFromConstPtr(Constant *C, // Instead of loading constant c string, use corresponding integer value // directly if string length is small enough. - std::string Str; - if (TD && GetConstantStringInfo(CE, Str) && !Str.empty()) { - unsigned StrLen = Str.length(); + StringRef Str; + if (TD && getConstantStringInfo(CE, Str) && !Str.empty()) { + unsigned StrLen = Str.size(); Type *Ty = cast(CE->getType())->getElementType(); unsigned NumBits = Ty->getPrimitiveSizeInBits(); // Replace load with immediate integer if the result is an integer or fp -- cgit v1.2.3
