Douglas Gregor b61c07aca0 When caching code completions for global declarations, keep track of 
the usage type of each declaration result, then compare those types to
the preferred type of the completion. This provides parity in the
priority calculation between the code-completion results produced
directly from Sema and those cached by ASTUnit. 

For the standard Cocoa.h (+ others) example, there's a penalty of 3-4
hundredeths of a second when caching the global results (for ~31,000
results), because we need an ASTContext-agnostic representation of
types for the comparison, and therefore we use... strings. Eventually,
we'd like to implement a more efficient ASTContext-agnostic encoding
of types.

Dan Gohman a573c41435 Revert r111031. The way LLVM defines loop invariance, the property of an 
expression being loop invariant is not equivalent to the property of
properly dominating the loop header.

Other optimizations have also made this optimization less important.

Dan Gohman 797a1dbb1c To create a copy of a SmallVector with an element removed from the 
middle, copy the elements in two groups, rather than copying all the
elements and then doing an erase on the middle of the result. These
are SmallVectors, so we shouldn't expect to hit dynamic allocation
in the common case.

Douglas Gregor 6e24033bd2 When caching global completion results, keep track of the simplified 
type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.

This gets us one step closer to parity of the cached completion
results with the non-cached completion results.

Dan Gohman 89fdbaf99a Instead of having CollectSubexpr's categorize operands as interesting or 
uninteresting, just put all the operands on one list and make
GenerateReassociations make the decision about what's interesting.
This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call.

llvm-svn: 111133
 2010-08-16 15:50:00 +00:00
Dan Gohman 9b7632df26 Put add operands in ScalarEvolution-canonical order, when convenient. 
This isn't necessary, because ScalarEvolution sorts them anyway,
but it's tidier this way.

Dan Gohman f99ba9671e Specialize FoldingSetTrait<SCEV>, providing implementations of node 
comparison and hash computation which don't require constructing
temporary ID values.

 2010-08-16 15:31:45 +00:00
Dan Gohman 9c9ce53b29 Add hooks to FoldingSetTrait to allow specializations to provide 
implementations of equality comparison and hash computation. This
can be used to optimize node lookup by avoiding creating lots of
temporary ID values just for hashing and comparison purposes.

address got DCEd.

Jordy Rose 722f558f07 Model the effects of strcpy() and stpcpy() in CStringChecker. Other changes: 
- Fix memcpy() and friends to actually invalidate the destination buffer.
- Emit a different message for out-of-bounds buffer accesses if the buffer is being written to.
- When conjuring symbols, let ValueManager figure out the type.

Jordy Rose df28e8ec41 - Allow making ElementRegions with complex offsets (expressions or symbols) for the purpose of bounds-checking. 
- Rewrite GRState::AssumeInBound to actually do that checking, and to use the normal constraint path.
- Remove ConstraintManager::AssumeInBound.
- Teach RegionStore and FlatStore to ignore those regions for now.

David Chisnall 589a494352 Pass some things to the linker that gcc passes. -r is the only one of these that I'm sure about, but the others seem to be listed on FreeBSD by gcc -dumpspecs, so I hope they're right. Apparently -r is also not passed on GNU/Linux (and should be), but I can't see where the toolchain definition for this platform live.
