Reid Spencer c635f47d9a For PR950: 
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.

Reid Spencer 266e42b312 For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

Reid Spencer bb65ebf9a1 Replace inferred getCast(V,Ty) calls with more strict variants. 
Rename getZeroExtend and getSignExtend to getZExt and getSExt to match
the the casting mnemonics in the rest of LLVM.

Bill Wendling f3baad3ee1 Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are 
now cerr, cout, and NullStream resp.

Reid Spencer 6c38f0bb07 For PR950: 
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.

vector accesses like we handle out-of-range array accesses.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Reid Spencer e0fc4dfc22 For PR950: 
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.

Reid Spencer be535661cc For PR780: 
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
   with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

llvm-svn: 28715
 2006-06-07 22:00:26 +00:00
Reid Spencer 5861659a1e Change from using a stub function to a stub variable for passing to the 
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

Chris Lattner 071faf25e0 Be more conservative with our symbolic alias analysis. In particular, 
don't assume that A[1][0] and A[0][i] can't alias.  "i" might be out of
range, or even negative.  This fixes a miscompilation of 188.ammp (which
does bad pointer tricks) with the new CFE.

Chris Lattner bb0bfc4702 By definition, 'tail' calls cannot access the stack frame of their caller.
