From a8f0bc04d33390d06115b80ad22a081598ba0fca Mon Sep 17 00:00:00 2001 From: Erick Tryzelaar Date: Wed, 19 Aug 2009 02:53:07 +0000 Subject: [PATCH] Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType. gcc-4.4 was optimizing away comparisons against SimpleValueType when it was compared to a value larger than the largest value in the enum. This patch works around it by adding one extra item to the enum so that these tests will now be valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79401 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/ValueTypes.h | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/include/llvm/CodeGen/ValueTypes.h b/include/llvm/CodeGen/ValueTypes.h index 4cdad67a736..978ea44f9d7 100644 --- a/include/llvm/CodeGen/ValueTypes.h +++ b/include/llvm/CodeGen/ValueTypes.h @@ -111,7 +111,12 @@ namespace llvm { iPTR = 255, // LastSimpleValueType - The greatest valid SimpleValueType value. - LastSimpleValueType = 255 + LastSimpleValueType = 255, + + // FirstExtendedValueType - This sentinel is needed so that gcc 4.4 won't + // optimize away checks of a SimpleValueType compared to + // LastSimpleValueType+1. + FirstExtendedValueType = 256 }; SimpleValueType SimpleTy; -- 2.34.1
