Dan Gohman 4f2e69c229 Trim unnecessary headers. Code in Analysis shouldn't use Transforms 
headers due to library dependencies.

Dan Gohman e5d2a04ace Constant-fold ptrtoint+add+inttoptr to gep when the pointer is an 
array and the add is within range. This helps simplify expressions
expanded by ScalarEvolutionExpander.

Dan Gohman c6bb55ba53 Factor out a common base class between SCEVCommutativeExpr and 
SCEVAddRecExpr. This eliminates redundant code for visiting
all the operands of an expression.

Douglas Gregor ae1e53c87b Compute the canonical template name when building a template 
specialization type for a dependent template name.

Douglas Gregor 6bc50585e3 Start canonicalizing template names. This is not yet complete, but it 
improves type identity with dependent types.

Ted Kremenek 75edb2e8a0 Bug fix: Not all ConstraintManagers always return a null state when setting 
isFeasible to false. This is something we may wish to do further validation on.

Argyrios Kyrtzidis baf3fee885 Make DwarfWriter::RecordInlinedFnStart more like the other DwarfWriter's methods:

Dan Gohman 39b480cea0 Use stable_sort instead of plain sort to avoid the risk of generating 
trivially different code on different hosts (due to differing
std::sort implementations).

Daniel Dunbar f9d90275f9 Handle -march for the LLVM recognized cpu names. 
- x86 target feature handling should not be feature complete, even if
   the code quality is lacking.

Ted Kremenek bb8d546208 Refactor BugReporter interface to have a new 'BugReporterContext' and 
'BugReporterVisitor'. This simplifies callbacks from BugReporter to BugReports
(via VisitNode). It also lays the foundation for arbitrary visitor "call backs"
that can be registered to a BugReporterContext as a PathDiagnostic is
constructed. These call backs can help operate as separate "experts" that can
work on constructed pieces of a PathDiagnostic for which they possess special
knowledge.

Bill Wendling 4d11693f33 - Move some debug fields to coincide with how GCC emits them. No functionality 
change.
- Reformatting.

llvm-svn: 71118
 2009-05-06 21:21:34 +00:00
Daniel Dunbar bb36aed06b More x86 target feature support. 
- Apologies for the extremely gross code duplication, I want to get
   this working and then decide how to get this information out of the
   back end.

 - This replaces -m[no-]sse4[12] by -m[no-]sse4, it appears gcc
   doesn't distinguish them?

 - -msse, etc. now properly disable/enable related features.

 - Don't always define __SSE3__...

 - The main missing functionality bit here is that we don't initialize
   the features based on the CPU for all -march options.

Dale Johannesen 72b6582c0f Use X86AddrNumOperands instead of magic constant one 
more place.  This fixes a bunch of x86-64 JIT regressions.
(Introduced when the value of the magic constant changed
in 68645.  At the time apparently nobody noticed; failures
were hidden in 70343-70439 by an unrelated bug, so showed
up again as "new" failures in 70440.)

 2009-05-06 18:25:01 +00:00
Ted Kremenek 0626df4eeb Fix analyzer regression reported in PR 4164: 
- Update the old StoreManager::CastRegion to strip off 'ElementRegions' when
  casting to void* (Zhongxing: please validate)
- Pass-by-reference argument invalidation logic in CFRefCount.cpp:
  - Strip ElementRegions when the ElementRegion is just a 'raw data' view
    on top of the underlying typed region.

Zhongxing Xu ea8c48d5a1 Improve RegionStoreManager::getSizeInElements() 
- add a static function getTypeWidth(), which computes the width of a type
   with the help of TargetInfo.
 - no-outofbounds.c now passes for region store.

Duncan Sands 9759f2e063 Fix PR3754: don't mark functions that wrap MallocInst with 
the readnone.  Since MallocInst is scheduled for deletion
it doesn't seem worth doing anything more subtle, such as
having mayWriteToMemory return true for MallocInst.

 2009-05-06 08:33:50 +00:00
Zhongxing Xu 24ed0b28a8 The super region of ElementRegion no longer needs to be TypedRegion. In the 
future we would create ElementRegion directly on top of typeless regions.
