From 15aab8a723f9a316fe387af22a21b2a3abbaa066 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Thu, 22 Feb 2007 00:58:45 +0000 Subject: [PATCH] When converting from 64 to 32-bits, use the actual number of words to extract the value, not the number of words implied by the active bits. This fixes numerous, but not all divide bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34484 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/APInt.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/Support/APInt.cpp b/lib/Support/APInt.cpp index c8ab2d762b6..03652a8f893 100644 --- a/lib/Support/APInt.cpp +++ b/lib/Support/APInt.cpp @@ -1177,7 +1177,7 @@ void APInt::divide(const APInt LHS, uint32_t lhsWords, uint32_t *U = new uint32_t[m + n + 1]; memset(U, 0, (m+n+1)*sizeof(uint32_t)); for (unsigned i = 0; i < lhsWords; ++i) { - uint64_t tmp = (lhsWords == 1 ?
