Duncan Sands e2881053c9 Remove the one-definition-rule version of extern_weak 
linkage: this linkage type only applies to declarations,
but ODR is only relevant to globals with definitions.

Nate Begeman 664cf27602 Allow cross-process JIT to handle MachineRelocations of the ExternalSymbol 
variety.  For example, an i64 div might turn into a call to __divdi3 during
legalization.

Chris Lattner 43d6377f89 reapply my previous patch (r66358) with a tweak to set the 
alignment of the generated constant pool entry to the
desired alignment of a type.  If we don't do this, we end up
trying to do movsd from 4-byte alignment memory.  This fixes
450.soplex and 456.hmmer.

Ted Kremenek 90e213f025 RegionStore::getLValueElement: Handle the case where the signedness of the 
offset may be different that the base. Ultimately we need a better solution for
these issues, but this point-by-point fixes are gradually outlining the scope of
the problem.

Ted Kremenek 154c963317 Add utility method to BasicValueFactory to convert an APSInt to one of a different sign.

Ted Kremenek 0fa538528e Fix PR 3780: In one code path in BasicValueFactory::getValue() we would not 
return an unsigned integer for a null pointer value.

Ted Kremenek 3f5a85ad06 SimpleConstraintManager doesn't reason about bitwise-constraints on symbolic 
values. Indicating this in 'canReasonAbout' allows GRExprEngine to recover
path-sensitivity in some cases.

llvm-svn: 66628
 2009-03-11 02:29:48 +00:00
Ted Kremenek 44c12ef615 GRExprEngine: For places we might conjure up a new symbol to recover 
path-sensitivity, beyond checking to see if the value is "unknown" also check if
the ConstraintManager can handle the SVal. This allows us to recover some
path-sensitivity by actually discarding some information.

 2009-03-11 02:23:27 +00:00
Ted Kremenek 4e34f958f4 Added method "canReasonAbout" to ConstraintManager. This method returns true if 
a ConstraintManager can usefully reason about the given SVal.

Ted Kremenek 39df18f6da Display the exploded graph before calling BugReporter.FlushReports(). The latter 
deletes all registered BugTypes from BugReporter, and thus we need to display
the graph first.

Evan Cheng 64b3f9d7a7 Two coalescer fixes in one. 
1. Use the same value# to represent unknown values being merged into sub-registers.
2. When coalescer commute an instruction and the destination is a physical register, update its sub-registers by merging in the extended ranges.

Chris Lattner 0cdaa2e525 position the caret properly on asm string diagnostics, e.g.: 
Sema/asm.c:64:9: error: invalid % escape in inline assembly string
  asm("%!" : );   // expected-error {{invalid % escape in inline assembly string}}

Bill Wendling 86c2656416 Just make the Dwarf timer group static inside of the getter function. No need to alloc/dealloc. 
llvm-svn: 66591

Bill Wendling 6418590596 - Fix misspelled method name.

Douglas Gregor 8145742349 Partial fix for PR3310, concerning type-checking for tentative 
definitions. We were rejecting tentative definitions of incomplete
(which is bad), and now we don't.

This fix is partial because we don't do the end-of-translation-unit
initialization for tentative definitions that don't ever have any
initializers specified.

Bill Wendling a5c8e50ea6 - Create GetOrCreateSourceID from getOrCreateSourceID. GetOrCreateSourceID is 
the untimed version of getOrCreateSourceID. getOrCreateSourceID calls
  GetOrCreateSourceID, of course.

- Move some methods into the "private" section. Constify at least one method.

- General clean-ups.
