2011-10-14An instruction's operands aren't necessarily instructions or constants. TheyNick Lewycky
could be arguments, for example. No testcase because this is a bug-fix broken out of a larger optimization patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141951 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-14Ban rematerializable instructions with side effects.Jakob Stoklund Olesen
TableGen infers unmodeled side effects on instructions without a pattern. Fix some instruction definitions where that was overlooked. Also raise an error if a rematerializable instruction has unmodeled side effects. That doen't make any sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141929 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-14V_SET0 has no side effects.Jakob Stoklund Olesen
TableGen will mark any pattern-less instruction as having unmodeled side effects. This is extra bad for V_SET0 which gets rematerialized a lot. This was part of the cause for PR11125, but the real bug was fixed in r141923. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141924 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-14Add value numbers when spilling dead defs.Jakob Stoklund Olesen
When spilling around an instruction with a dead def, remember to add a value number for the def. The missing value number wouldn't normally create problems since there would be an incoming live range as well. However, due to another bug we could spill a dead V_SET0 instruction which doesn't read any values. The missing value number caused an empty live range to be created which is dangerous since it doesn't interfere with anything. This fixes part of PR11125. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141923 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-13Avoid undefined behavior in negation in LSR. Patch by Ahmed Charles.Eli Friedman
Someone more familiar with LSR should double-check that the extra cast is actually doing the right thing in the overflow cases; I'm not completely confident that's that case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141916 91177308-0d34-0410-b5e6-96231b3b80d8
