* relax some typesChris Lattner2007-01-071-1/+1
| | | | llvm-svn: 32980
* For PR950:Reid Spencer2006-12-311-9/+9
| | | | | | | | | | | | | This patch replaces signed integer types with signless ones: 1. [US]Byte -> Int8 2. [U]Short -> Int16 3. [U]Int -> Int32 4. [U]Long -> Int64. 5. Removal of isSigned, isUnsigned, getSignedVersion, getUnsignedVersion and other methods related to signedness. In a few places this warranted identifying the signedness information from other sources. llvm-svn: 32785
* Replace CastInst::createInferredCast calls with more accurate castReid Spencer2006-12-131-2/+1
| | | | | | creation calls. llvm-svn: 32521
* For PR950:Reid Spencer2006-11-271-5/+9
| | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931
* For PR950:Reid Spencer2006-10-201-6/+6
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063

* When a function takes a variable number of pointer arguments, with a zeroJeff Cohen2005-10-231-2/+3
| | | | | | | | | | | | | pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. llvm-svn: 23888
