From 3e2dda63d03b84e558c757fae67ee8fe028b9124 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Mon, 28 Apr 2008 20:25:15 +0000 Subject: [PATCH] Fix a pointer-arithmetic bug that caused 64-bit host pointer values to be truncated to 32 bits. This fixes the recent Benchmarks/McCat/09-vor regression on x86-64, among other things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50372 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/Allocator.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Support/Allocator.cpp b/lib/Support/Allocator.cpp index 8ccd3908446..4b6f9ff7b13 100644 --- a/lib/Support/Allocator.cpp +++ b/lib/Support/Allocator.cpp @@ -48,7 +48,7 @@ public: void *Allocate(unsigned AllocSize, unsigned Alignment, MemRegion **RegPtr) { char* Result = (char*) (((uintptr_t) (NextPtr+Alignment-1)) - & ~(Alignment-1)); + & ~((uintptr_t) Alignment-1)); // Speculate the new value of NextPtr. char* NextPtrTmp = Result + AllocSize; -- 2.34.1
