* [SystemZ] Handle extensions in RxSBG optimizationsRichard Sandiford2013-10-161-3/+2
| | | | | | | | The input to an RxSBG operation can be narrower as long as the upper bits are don't care. This fixes a FIXME added in r192783. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192790 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Improve handling of SETCCRichard Sandiford2013-10-163-16/+260
| | | | | | | | | We previously used the default expansion to SELECT_CC, which in turn would expand to "LHI; BRC; LHI". In most cases it's better to use an IPM-based sequence instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192784 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle (shl (anyext (shr ...))) in SimpilfyDemandedBitsRichard Sandiford2013-10-161-0/+67
| | | | | | | | | | | This is really an extension of the current (shl (shr ...)) -> shl optimization. The main difference is that certain upper bits must also not be demanded. The motivating examples are the first two in the testcase, which occur in llvmpipe output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192783 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: Better handling of tricky symbol and section namesHans Wennborg2013-10-163-4/+4
| | | | | | | | | | | | | | | | | Because of win32 mangling, we produce symbol and section names with funny characters in them, most notably @ characters. MC would choke on trying to parse its own assembly output. This patch addresses that by: - Making @ trigger quoting of symbol names - Also quote section names in the same way - Just parse section names like other identifiers (to allow for quotes) - Don't assume @ signifies a symbol variant if it is in a string.

* Enable MI Sched for x86.Andrew Trick2013-10-1565-278/+336
| | | | | | | | | | | | | | | | | | | | | | | | | | This changes the SelectionDAG scheduling preference to source order. Soon, the SelectionDAG scheduler can be bypassed saving a nice chunk of compile time. Performance differences that result from this change are often a consequence of register coalescing. The register coalescer is far from perfect. Bugs can be filed for deficiencies. On x86 SandyBridge/Haswell, the source order schedule is often preserved, particularly for small blocks. Register pressure is generally improved over the SD scheduler's ILP mode. However, we are still able to handle large blocks that require latency hiding, unlike the SD scheduler's BURR mode. MI scheduler also attempts to discover the critical path in single-block loops and adjust heuristics accordingly. The MI scheduler relies on the new machine model. This is currently unimplemented for AVX, so we may not be generating the best code yet. Unit tests are updated so they don't depend on SD scheduling heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192750 91177308-0d34-0410-b5e6-96231b3b80d8

This is valid only if the related instructions are in that same basic block, otherwise we may reference variables that were not live accross basic blocks resulting in undefined virtual registers.

* MachineSink: Fix and tweak critical-edge breaking heuristic.Will Dietz2013-10-149-20/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per original comment, the intention of this loop is to go ahead and break the critical edge (in order to sink this instruction) if there's reason to believe doing so might "unblock" the sinking of additional instructions that define registers used by this one. The idea is that if we have a few instructions to sink "together" breaking the edge might be worthwhile. This commit makes a few small changes to help better realize this goal: First, modify the loop to ignore registers defined by this instruction. We don't sink definitions of physical registers, and sinking an SSA definition isn't going to unblock an upstream instruction. Second, ignore uses of physical registers. Instructions that define physical registers are rejected for sinking, and so moving this one won't enable moving any defining instructions. As an added bonus, while virtual register use-def chains are generally small due to SSA goodness, iteration over the uses and definitions (used by hasOneNonDBGUse) for physical registers like EFLAGS can be rather expensive in practice. (This is the original reason for looking at this) Finally, to keep things simple continue to only consider this trick for registers that have a single use (via hasOneNonDBGUse), but to avoid spuriously breaking critical edges only do so if the definition resides in the same MBB and therefore this one directly blocks it from being sunk as well. If sinking them together is meant to be, let the iterative nature of this pass sink the definition into this block first. Update tests to accomodate this change, add new testcase where sinking avoids pipeline stalls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192608 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove kill flags after if conversion if necessaryMatthias Braun2013-10-111-0/+30
| | | | | | | | | | | | | | | | | | | When if converting something like: true: ... = R0<kill> false: ... = R0<kill> then the instructions of the true block must not have a <kill> flag anymore, as the instruction of the false block follow and do still read the R0 value. Specifically this patch determines the set of register live-in in the false block (possibly after simulating the liveness changes of the duplicated instructions). Each of these live-in registers mustn't be killed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192482 91177308-0d34-0410-b5e6-96231b3b80d8
