Eric Christopher a964f4de76 Move X86InstrFPStack.td over to PseudoI as well. 
llvm-svn: 120470
 2010-11-30 21:57:32 +00:00
Chris Lattner 51d67ce2ff switch RemoveAccessedObjects to use AliasAnalysis::Location to simplify 
the code.  We now get accurate sizes on Loads, though it surely doesn't
matter in practice.

 2010-11-30 21:47:58 +00:00
Chris Lattner f80b39986f two improvements to RemoveAccessedObjects: 
1. if the underlying pointer passed in can be resolved
   to any argument or alloca, then we don't need to scan.
   Previously we would only avoid the scan if the alloca
   or byval was actually considered dead.
2. The dead store processing code is itself completely
   dead and didn't handle volatile stores right anyway,
   so delete it.  This allows simplifying the interface
   to RemoveAccessedObjects.

Eric Christopher a87065807f Migrate X86InstrControl.td to use PseudoI and fix a couple of 80-col violations 
while I'm in there.

Chris Lattner 7fe08b67fa remove the "undead" terminology, which is nonstandard and never 
made sense to me.  We now have a set of dead stack objects, and
they become live when loaded.  Fix a theoretical problem where
we'd pass in the wrong pointer to the alias query.

Chris Lattner 127818d746 move call handling in handleEndBlock up a bit, and simplify it. 
If the call might read all the allocas, stop scanning early.
Convert a vector to smallvector, shrink SmallPtrSet to 16 instead
of 64 to avoid crazy linear scans.

Ted Kremenek dbd89971ff Performance optimization on ImmutableMap/ImmutableSet: 
- Use a DenseSet instead of a FoldingSet to cache
canonicalized nodes.  This reduces the overhead
of double-hashing.

- Use reference counts in ImutAVLTree to much
more aggressively recover tree nodes that are
no longer usable.  We can generate many
transient nodes while using add() and remove()
on ImmutableSet/ImmutableMaps to generate a final
set/map.

For the clang static analyzer (the main client
of these data structures), this results in
a slight speedup (0.5%) when analyzing sqlite3,
but much more importantly results in a 30-60%
reduction in peak memory usage when the analyzer
is analyzing a given function in a file.  On
average that's about a ** 44% reduction ** in the
memory footprint of the static analyzer.
