* Enable support for precise scheduling of the instruction selectionAndrew Trick2011-01-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | DAG. Disable using "-disable-sched-cycles". For ARM, this enables a framework for modeling the cpu pipeline and counting stalls. It also activates several heuristics to drive scheduling based on the model. Scheduling is inherently imprecise at this stage, and until spilling is improved it may defeat attempts to schedule. However, this framework provides greater control over tuning codegen. Although the flag is not target-specific, it should have very little affect on the default scheduler used by x86. The only two changes that affect x86 are: - scheduling a high-latency operation bumps the current cycle so independent operations can have their latency covered. i.e. two independent 4 cycle operations can produce results in 4 cycles, not 8 cycles. - Two operations with equal register pressure impact and no latency-based stalls on their uses will be prioritized by depth before height (height is irrelevant if no stalls occur in the schedule below this point). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123971 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | callee-saved registers at the end of the lists. Also prefer to avoid using the low registers that are in register subclasses required by certain instructions, so that those registers will more likely be available when needed. This change makes a huge improvement in spilling in some cases. Thanks to Jakob for helping me realize the problem. Most of this patch is fixing the testsuite. There are quite a few places where we're checking for specific registers. I changed those to wildcards in places where that doesn't weaken the tests. The spill-q.ll and thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch of live values to force spills on those tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116055 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | modeled as icmp / fcmp + sext. This is turned into a vsetcc by dag combine (yes, not a good long term solution). The targets can then isel the vsetcc to the appropriate instruction. The trouble arises when the result of a vector cmp + sext is then and'ed with all ones. Instcombine will turn it into a vector cmp + zext, dag combiner will miss turning it into a vsetcc and hell breaks loose after that. Teach dag combine to turn a vector cpm + zest into a vsetcc + and 1. This fixes rdar://7923010. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104094 91177308-0d34-0410-b5e6-96231b3b80d8
