From 382da62ec274feead85e7be364ab5d4fd0281d98 Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Mon, 15 Dec 2008 07:29:55 +0000 Subject: It turns out that "align 1" and unaligned are different. Add a bias to the alignment attribute such that 0 means unaligned. This will probably require a rebuild of llvm-gcc because of the change to Attributes.h. If you see many test failures on "make check", please rebuild your llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61030 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Bitcode/Writer/BitcodeWriter.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/Bitcode/Writer/BitcodeWriter.cpp') diff --git a/lib/Bitcode/Writer/BitcodeWriter.cpp b/lib/Bitcode/Writer/BitcodeWriter.cpp index 0555ed90f6..adf49a524a 100644 --- a/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -128,7 +128,8 @@ static void WriteAttributeTable(const ValueEnumerator &VE, // 5-bit log2 encoded value.
