2011-05-03Replace the "movnt" intrinsics with a native store + nontemporal metadata bit.Bill Wendling
<rdar://problem/8460511> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130791 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-03Gracefully handle invalid live ranges. Fix PR9831.Jakob Stoklund Olesen
Register coalescing can sometimes create live ranges that end in the middle of a basic block without any killing instruction. When SplitKit detects this, it will repair the live range by shrinking it to its uses. Live range splitting also needs to know about this. When the range shrinks so much that it becomes allocatable, live range splitting fails because it can't find a good split point. It is paranoid about making progress, so an allocatable range is considered an error. The coalescer should really not be creating these bad live ranges. They appear when coalescing dead copies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130787 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-03Implement some basic simplifications involving min/max, for exampleDuncan Sands
max(a,b) >= a -> true. According to my super-optimizer, these are by far the most common simplifications (of the -instsimplify kind) that occur in the testsuite and aren't caught by -std-compile-opts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130780 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-02Minimize the slot indexes spanned by register ranges created when splitting.Jakob Stoklund Olesen
When an interfering live range ends at a dead slot index between two instructions, make sure that the inserted copy instruction gets a slot index after the dead ones. This makes it possible to avoid the interference. Ideally, there shouldn't be interference ending at a deleted instruction, but physical register coalescing can sometimes do that to sub-registers. This fixes PR9823. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130687 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-02Add a SlotIndexes::insertMachineInstrInMaps to insert the instruction after ↵Jakob Stoklund Olesen
any null indexes. This makes a difference if a live interval is referring to a deleted instruction. It can be important to insert an instruction before or after a deleted instruction to avoid interference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130686 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-02In option typo correction, consider -foo=VALUE flags as two distinct parts. TheNick Lewycky
comments claimed it did this, but the LHS value was actually an unused variable. The new system considers only the '-foo' part when comparing it for typos against flags that have values, but still look at the whole string for flags that don't. That way, we'll still correct '-inst=combine' to '-instcombine'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130685 91177308-0d34-0410-b5e6-96231b3b80d8
