Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
 2007-05-02 21:39:20 +00:00
Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

llvm-svn: 33941

Reid Spencer 5301e7c605 For PR1136: Rename GlobalVariable::isExternal as isDeclaration to avoid 
confusion with external linkage types.

llvm-svn: 33663
 2007-01-30 20:08:39 +00:00
Chris Lattner 875d7b2b1d fit to 80 cols. 
Remove now-extraneous checks for ptr->ptr bitcasts.

Fix PR1109 and Analysis/BasicAA/2007-01-13-BasePointerBadNoAlias.ll.  We
need to consider arbitrary sized objects when checking for nested GEP offsets.

llvm-svn: 33195

llvm-svn: 33125
 2007-01-12 18:20:48 +00:00
Reid Spencer cddc9dfe97 Implement review feedback for the ConstantBool->ConstantInt merge. Chris 
recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

llvm-svn: 33110
 2007-01-12 04:24:46 +00:00
Reid Spencer 542964f55b Rename BoolTy as Int1Ty. Patch by Sheng Zhou. 
llvm-svn: 33076
 2007-01-11 18:21:29 +00:00
Zhou Sheng 75b871fb1e For PR1043:

Remove ConstantIntegral and ConstantBool from LLVM.

llvm-svn: 33073
 2007-01-11 12:24:14 +00:00
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.

llvm-svn: 32785
 2006-12-31 05:48:39 +00:00
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.

llvm-svn: 32751
 2006-12-23 06:05:41 +00:00
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.

llvm-svn: 32514
 2006-12-12 23:36:14 +00:00
Bill Wendling f3baad3ee1 Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are 
now cerr, cout, and NullStream resp.

llvm-svn: 32298
 2006-12-07 01:30:32 +00:00
Bill Wendling a531ac291c Convert to using llvm streams instead of iostreams. 
llvm-svn: 31989
 2006-11-28 23:33:06 +00:00
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.

llvm-svn: 31931
 2006-11-27 01:05:10 +00:00
Chris Lattner 5c833df633 remove redundant code 
llvm-svn: 31697

Chris Lattner ea2abe2384 Fix BasicAA/2006-11-03-BasicAAVectorCrash.ll by handling out-of-range 
vector accesses like we handle out-of-range array accesses.

llvm-svn: 31427
 2006-11-03 21:58:48 +00:00
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.

llvm-svn: 31380
 2006-11-02 20:25:50 +00:00
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.

llvm-svn: 31063

 2006-08-27 12:54:02 +00:00
Chris Lattner 996795b0dd Use hidden visibility to make symbols in an anonymous namespace get 
dropped.  This shrinks libllvmgcc.dylib another 67K

llvm-svn: 28975
 2006-06-28 23:17:24 +00:00
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.

llvm-svn: 28621
 2006-06-01 07:02:51 +00:00
Chris Lattner bb40a9fa58 Use autogenerated mod/ref info for intrinsics.

Chris Lattner 3e19c23765 Fix a crash compiling Obsequi 
llvm-svn: 26529
 2006-03-04 21:48:01 +00:00
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.

Testcase here: Analysis/BasicAA/2006-03-03-BadArraySubscript.ll
