[llvm-commits] [SignlessTypes] CVS: llvm/lib/Transforms/IPO/GlobalOpt.cpp LowerSetJmp.cpp SimplifyLibCalls.cpp

Reid Spencer reid at x10sys.com
Wed Oct 18 20:58:57 PDT 2006



Changes in directory llvm/lib/Transforms/IPO:

GlobalOpt.cpp updated: 1.68 -> 1.68.2.1
LowerSetJmp.cpp updated: 1.29 -> 1.29.2.1
SimplifyLibCalls.cpp updated: 1.69 -> 1.69.2.1
---
Log message:

For PR950: http://llvm.org/PR950 :
This commit (on SignlessTypes branch) provides the first Iteration for 
moving LLVM away from Signed types. This patch removes the ConstantSInt
and ConstantUInt classes from Type.h and makes all necessary changes in
LLVM to compensate.
