2010-11-30Enable sibling call optimization of libcalls which are expanded duringEvan Cheng
legalization time. Since at legalization time there is no mapping from SDNode back to the corresponding LLVM instruction and the return SDNode is target specific, this requires a target hook to check for eligibility. Only x86 and ARM support this form of sibcall optimization right now. rdar://8707777 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120501 91177308-0d34-0410-b5e6-96231b3b80d8

may-aliasing stores that partially overlap with different base pointers. This implements PR6043 and the non-variable part of PR8657 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120485 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30* Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same asBill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120482 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30Simplify the encoding of reg+/-imm12 values that allow PC-relative encoding. ↵Owen Anderson
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120481 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-30switch RemoveAccessedObjects to use AliasAnalysis::Location to simplifyChris Lattner
the code. We now get accurate sizes on Loads, though it surely doesn't matter in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120469 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30two improvements to RemoveAccessedObjects:Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120467 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30Migrate X86InstrControl.td to use PseudoI and fix a couple of 80-col violationsEric Christopher
while I'm in there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120466 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30remove the "undead" terminology, which is nonstandard and never Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120465 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30move call handling in handleEndBlock up a bit, and simplify it.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120463 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30Performance optimization on ImmutableMap/ImmutableSet:Ted Kremenek
- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120459 91177308-0d34-0410-b5e6-96231b3b80d8
