2011-07-05ARM estimateStackSize() needs to account for simplified call frames.Jim Grosbach
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
2011-07-05Fix PR10277.Jakob Stoklund Olesen
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

2011-07-04SuccIterator on bbs without terminator instsTobias Grosser
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

2011-07-04Move early tail duplication earlier.Rafael Espindola
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

2011-07-04Fix PR10244.Jakob Stoklund Olesen
A split point inserted in a block with a landing pad successor may be hoisted above the call to ensure that it dominates all successors. The code that handles the rest of the basic block must take this into account. I am not including a test case, it would be very fragile. PR10244 comes from building clang with exceptions enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134369 91177308-0d34-0410-b5e6-96231b3b80d8
