Dan Gohman 3439262586 Add a comment to clarify why there isn't any code in this spot.

 2009-07-20 23:54:43 +00:00
Dan Gohman 00c1aaec5a Remove the code that tried to evaluate whether (A pred B) is known 
by determining if (B pred (B-A)) is known, as it doesn't handle
overflow correctly.

Dale Johannesen a2d2adfa4e Make sure a global matching asm 'i' constraint gets its 
flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)
gcc.apple/asm-block-25.c (test passed before by
accident, but generated code was wrong)

Dale Johannesen ade297d496 Move stripping of bitcasts in inline asm arguments 
to a place where it affects everything.  Occurs
only on calls AFAIK.

Mike Stump 0d76d075e4 Add yet more analysis for CFGs involving conditionals that are actually constant.

Fariborz Jahanian 83381cc9a6 Move EmitCtorPrologue to CGCXX. Add an assert and FIXMEs.

Ted Kremenek 834e2f69da Enhanced IsReinterpreted() (RegionStore.cpp) to reason about higher-order 
pointers.

Enhanced RegionStoreManager::Retrieve() to handle automatic casts when the
loaded value is different from the requested value. This should be refined over
time, but essentially we should always symbolicate locations as locations, and
convert them to non-locations on demand.

These changes now cause 'misc-ps.m' to pass again.

Douglas Gregor d12df6b160 Reuse VarDecl::Init to store the default argument of a ParmVarDecl, 
reducing the size of ParmVarDecl by one pointer. Also means that we'll 
properly (de-)serialize default arguments in C++ PCH files.

David Greene 40c68ad3bb Re-apply 75490, 75806 and 76177 with fixes and tests. Efficiency comes

locs and vis versa.

Bill Wendling dde1a8eef4 Pass in the unfortunately named "LessPrivatePrefix" for the 
"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...

llvm-svn: 76466
 2009-07-20 20:38:59 +00:00
Bill Wendling 2dd0bf8db0 Change the casting of linkage types into a map. This makes this much more robust 
as it no longer depends upon two different enums being kept in sync with each
other.

llvm-svn: 76465
 2009-07-20 20:34:46 +00:00
Dan Gohman e29ed8c857 Clarify that OverflowingBinaryOperator is not used for SDiv, even though 
SDiv is a binary operation that can overflow.

Kevin Enderby ee5513582d Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

Daniel Dunbar 2b11c7de4a Add MCAsmLexer interface. 
- This provides the AsmLexer interface to the target specific assembly parsers.

 2009-07-20 20:01:54 +00:00
Evan Cheng 027d9f93ea Fix some sub-reg coalescing bugs where the coalescer wasn't updating the resulting interval's register class. 
llvm-svn: 76458

Eli Friedman 2aa1a2a8f3 Remove FIXME that was already fixed.

Douglas Gregor 959cc7aaaa When a field is variable-sized or is an array with a negative size, 
don't replace the type of the field with 'int', from Enea Zaffanella!

llvm-svn: 76454
 2009-07-20 18:55:14 +00:00
Daniel Dunbar 3c2a893ac7 Add MCAsmParser interface.

   parsers.

Ted Kremenek 619eece347 Update DataflowSolver to handle the case where a successor/predecessor block 
could be NULL. This allows the solver to handle optimized CFGs where branches
can be determined during CFG-construction to be infeasible.

llvm-svn: 76452
 2009-07-20 18:52:34 +00:00
Douglas Gregor 47d2859b3e Improve GCC compatibility by allowing static tentative definitions of 
incomplete type (with a warning), from Enea Zaffanella!

llvm-svn: 76451
 2009-07-20 18:46:59 +00:00
Ted Kremenek af9f362840 Enhance GRBranchNodeBuilderImpl (part of GRCoreEngine) to understand the case 
where the true or false CFGBlock* for a branch could be NULL. This will handle
the case where we can determine during CFG construction that a branch is
infeasible.

llvm-svn: 76445
 2009-07-20 17:59:32 +00:00
Steve Naroff accc488785 5 cleanups to ObjCObjectPointerType work: 
- Remove Sema::CheckPointeeTypesForAssignment(), a temporary API I added to ease migration to ObjCObjectPointerType. Convert Sema::CheckAssignmentConstraints() to no longer depend on the temporary API.
- Sema::ConvertDeclSpecToType(): Replace a couple FIXME's with an important comment/example.
- Sema::GetTypeForDeclarator(): Get the protocol's from the interface, NOT the declspec (to support the following C typedef idiom: "typedef C<P> T; T *obj").
- Sema::ObjCQualifiedIdTypesAreCompatible(): Removed some dead code.
- ASTContext::getObjCEncodingForTypeImpl(): Some minor cleanups.

Chris Lattner 470a8da807 use ExpandInlineAsm on TargetLowering instead of TargetAsmInfo.
