* Fix a subtle issue in SmallVector. The following code did not work as expected:Owen Anderson2011-07-062-22/+35
| | | | | | | | | | vec.insert(vec.begin(), vec[3]); The issue was that vec[3] returns a reference into the vector, which is invalidated when insert() memmove's the elements down to make space. The method needs to specifically detect and handle this case to correctly match std::vector's semantics. Thanks to Howard Hinnant for clarifying the correct behavior, and explaining how std::vector solves this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134554 91177308-0d34-0410-b5e6-96231b3b80d8

* Mark ARM pseudo-instructions as isPseudo.Jim Grosbach2011-07-061-5/+3
| | | | | | | | | | | | This allows us to remove the (bogus and unneeded) encoding information from the pseudo-instruction class definitions. All of the pseudos that haven't been converted yet and still need encoding information instance from the normal instruction classes and explicitly set isCodeGenOnly, and so are distinct from this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134540 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't require pseudo-instructions to carry encoding information.Jim Grosbach2011-07-067-7/+29
| | | | | | | | | | | | For now this is distinct from isCodeGenOnly, as code-gen-only instructions can (and often do) still have encoding information associated with them. Once we've migrated all of them over to true pseudo-instructions that are lowered to real instructions prior to the printer/emitter, we can remove isCodeGenOnly and just use isPseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134539 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM estimateStackSize() needs to account for simplified call frames.Jim Grosbach2011-07-051-7/+39
| | | | | | | | | | | | | If the function allocates reserved stack space for callee argument frames, estimateStackSize() needs to account for that, as it doesn't show up as ordinary frame objects. Otherwise, a callee with a large argument list will throw off the calculations for whether to allocate an emergency spill slot and we get assert() failures in the register scavenger. rdar://9715469 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134415 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix PR10277.Jakob Stoklund Olesen2011-07-053-0/+108
| | | | | | | | | | | | | | | Remat during spilling triggers dead code elimination. If a phi-def becomes unused, that may also cause live ranges to split into separate connected components. This type of splitting is different from normal live range splitting. In particular, there may not be a common original interval. When the split range is its own original, make sure that the new siblings are also their own originals. The range being split cannot be used as an original since it doesn't cover the new siblings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134413 91177308-0d34-0410-b5e6-96231b3b80d8

* SuccIterator on bbs without terminator instsTobias Grosser2011-07-041-3/+11
| | | | | | | | | Remove the assert that triggers if SuccIterator is constructed for a basic block without a terminator instruction. Instead of triggering an assert a succ_end() iterator is returned. This models a basic block with zero successors and allows us to use F->viewCFG() on incompletely constructed functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134398 91177308-0d34-0410-b5e6-96231b3b80d8

* Move early tail duplication earlier.Rafael Espindola2011-07-041-6/+6
| | | | | | | | | | | | | | This fixes the issue noted in PR10251 where early tail dup of bbs with indirectbr would cause a bb to be duplicated into a loop preheader and then into its predecessors, creating phi nodes with identical operands just before register allocation. This helps with jsinterp.o size (__TEXT goes from 163568 to 126656) and a bit with performance 1.005x faster on sunspider (jits still enabled). The result on webkit with the jit disabled is more significant: 1.021x faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134372 91177308-0d34-0410-b5e6-96231b3b80d8
