2009-05-07Fix pr4100. Do not remove no-op copies when they are dead. The registerBob Wilson
scavenger gets confused about register liveness if it doesn't see them. I'm not thrilled with this solution, but it only comes up when there are dead copies in the code, which is something that hopefully doesn't happen much. Here is what happens in pr4100: As shown in the following excerpt from the debug output of llc, the source of a move gets reloaded from the stack, inserting a new load instruction before the move. Since that source operand is a kill, the physical register is free to be reused for the destination of the move. The move ends up being a no-op, copying R3 to R3, so it is deleted. But, it leaves behind the load to reload %reg1028 into R3, and that load is not updated to show that it's destination operand (R3) is dead. The scavenger gets confused by that load because it thinks that R3 is live. Starting RegAlloc of: %reg1025<def,dead> = MOVr %reg1028<kill>, 14, %reg0, %reg0 Regs have values: Reloading %reg1028 into R3 Last use of R3[%reg1028], removing it from live set Assigning R3 to %reg1025 Register R3 [%reg1025] is never used, removing it from live set Alternative solutions might be either marking the load as dead, or zapping the load along with the no-op copy. I couldn't see an easy way to do either of those, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71196 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-07Revert 71165. It did more than just revert 71158 and it introducedDan Gohman
several regressions. The problem due to 71158 is now fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71176 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-07Revert r70876 and add a testcase (@c7) showing the problem:Duncan Sands
bits captured, but the pointer marked nocapture. In fact I now recall that this problem is why only readnone functions returning void were considered before! However keep a small fix that was also in r70876: a readnone function returning void can result in bits being captured if it unwinds, so test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71168 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-07Make ScalarEvolution's GroupByComplexity more thorough. In additionDan Gohman
to sorting SCEVs by their kind, sort SCEVs of the same kind according to their operands. This helps avoid things like (a+b) being a distinct expression from (b+a). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71160 91177308-0d34-0410-b5e6-96231b3b80d8
