From 8d2ea18346b1f6aef13410424f2a686ffc631108 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. llvm-svn: 61030 --- llvm/lib/Bitcode/Writer/BitcodeWriter.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'llvm/lib/Bitcode/Writer/BitcodeWriter.cpp') diff --git a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp index 0555ed90f64..adf49a524a3 100644 --- a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -128,7 +128,8 @@ static void WriteAttributeTable(const ValueEnumerator &VE, // 5-bit log2 encoded value.
