* Declaring local static in global blockFariborz Jahanian2010-11-302-3/+32
| | | | | | | literal declaration caused crash in CodeGen. This patch fixes it. pr8707 llvm-svn: 120486

| | | | | | | | may-aliasing stores that partially overlap with different base pointers. This implements PR6043 and the non-variable part of PR8657 llvm-svn: 120485

* * Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same asBill Wendling2010-11-305-90/+151
| | | | | | | | | | t_addrmode_s4, but with a different scaling factor. * Encode the Thumb1 load and store instructions. This involved a bit of refactoring (hi, Chris! :-). Some of the patterns became dead afterwards and were removed. llvm-svn: 120482
* Simplify the encoding of reg+/-imm12 values that allow PC-relative encoding. ↵Owen Anderson2010-11-305-90/+16
| | | | | | | | | This allows the Thumb2 encoding to share code with the ARM encoding, which gets use fixup support for free. It also allows us to fold away at least one codegen-only pattern. llvm-svn: 120481
* Fix handling of ARM negative pc-relative fixups for loads and stores.Jim Grosbach2010-11-302-9/+36

* Fixed a problem where m_register_info was not beingSean Callanan2010-11-301-1/+2
| | | | | | | | | copied by the copy constructor for ClangExpressionVariable. This meant that a NULL m_register_info wouldn't be copied, and instead the field was uninitialized, potentially confusing the materializer. llvm-svn: 120472
* Make DeleteDeadInstruction be a static function, move some code around.Chris Lattner2010-11-301-59/+64

* switch RemoveAccessedObjects to use AliasAnalysis::Location to simplifyChris Lattner2010-11-301-17/+13
| | | | | | | the code. We now get accurate sizes on Loads, though it surely doesn't matter in practice. llvm-svn: 120469
* two improvements to RemoveAccessedObjects:Chris Lattner2010-11-301-28/+7
| | | | | | | | | | | | | 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. llvm-svn: 120467
* Migrate X86InstrControl.td to use PseudoI and fix a couple of 80-col violationsEric Christopher2010-11-301-19/+15
| | | | | | while I'm in there. llvm-svn: 120466
* remove the "undead" terminology, which is nonstandard and never Chris Lattner2010-11-301-40/+47
| | | | | | | | 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. llvm-svn: 120465
* move call handling in handleEndBlock up a bit, and simplify it.Chris Lattner2010-11-301-37/+40
| | | | | | | | 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. llvm-svn: 120463

* Performance optimization on ImmutableMap/ImmutableSet:Ted Kremenek2010-11-302-88/+159
| | | | | | | | | | | | | | | | | | | | | | | | - 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. llvm-svn: 120459
