2010-07-13Add an assertion to make PR7542 fail consistently.Jakob Stoklund Olesen
LiveInterval::overlapsFrom dereferences end() if it is called on an empty interval. It would be reasonable to just return false - an empty interval doesn't overlap anything, but I want to know who is doing it first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108264 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Add support for empty named metadata too. This isn't particularlyDan Gohman
useful, but it is nice for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108262 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Fix LiveInterval::overlaps so it doesn't claim touching intervals overlap.Jakob Stoklund Olesen

2010-07-13Extend the r107852 optimization which turns some fp compare to code sequence ↵Evan Cheng
using only i32 operations. It now optimize some f64 compares when fp compare is exceptionally slow (e.g. cortex-a8). It also catches comparison against 0.0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108258 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Handle the case of a tail recursion in which the tail call is followedDuncan Sands
by a return that returns a constant, while elsewhere in the function another return instruction returns a different constant. This is a special case of accumulator recursion, so just generalize the existing logic a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108241 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13rotate CallInst operandsGabor Greif
with this commit the callee moves to the end of the operand array (from the start) and the call arguments now start at index 0 (formerly 1) this ordering is now consistent with InvokeInst this commit only flips the switch, functionally it is equivalent to r101465 I intend to commit several cleanups after a few days of soak period git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108240 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Don't add memory operands to storeRegToStackSlot / loadRegFromStackSlot results,Jakob Stoklund Olesen
they already have one. This fixes the himenobmtxpa miscompilation on ARM. The PostRA scheduler got confused by the double memoperand and hoisted a stack slot load above a store to the same slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108219 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-12Remove some code that doesn't appear to do anything. All the ARM callBob Wilson
instructions already have implicit defs of LR. The comment suggests that this is intended to fix something like pr6111, but it doesn't really do that either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108186 91177308-0d34-0410-b5e6-96231b3b80d8
