2008-11-22Cleanup of the [SU]ADDO type legalization code. Patch by Duncan!Bill Wendling
"It simplifies the type legalization part a bit, and produces better code by teaching SelectionDAG about the extra bits in an i8 SADDO/UADDO node. In essence, I spontaneously decided that on x86 this i8 boolean result would be either 0 or 1, and on other platforms 0/1 or 0/-1, depending on whether the platform likes it's boolean zero extended or sign extended." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59864 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-21Rename SDep's isSpecial to isArtificial, to make this field a littleDan Gohman
less mysterious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59782 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Rename "ADDO" to "SADDO" and "UADDO". The "UADDO" isn't equivalent to "ADDC"Bill Wendling
because the boolean it returns to indicate an overflow may not be treated like as a flag. It could be stored to memory, for instance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59780 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Implement the sadd_with_overflow intrinsic. This is converted intoBill Wendling
"ISD::ADDO". ISD::ADDO is lowered into a target-independent form that does the addition and then checks if the result is less than one of the operands. (If it is, then there was an overflow.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59779 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Use ComputeLatency in the MachineInstr scheduler.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59777 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Remove the CycleBound computation code from the ScheduleDAGRRListDan Gohman
schedulers. This doesn't have much immediate impact because targets that use these schedulers by default don't yet provide pipeline information. This code also didn't have the benefit of register pressure information. Also, removing it will avoid problems with list-burr suddenly starting to do latency-oriented scheduling on x86 when we start providing pipeline data, which would increase spilling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59775 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Implement ComputeLatency for MachineInstr ScheduleDAGs. FactorDan Gohman
some of the latency computation logic out of the SDNode ScheduleDAG code into a TargetInstrItineraries helper method to help with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59761 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Add UADDO and SADDO nodes. These will be used for determining an overflowBill Wendling
condition in an addition operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59760 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Change these schedulers to not emit no-ops. It turns out thatDan Gohman
the RR scheduler actually does look at latency values, but it doesn't use a hazard recognizer so it has no way to know when a no-op is needed, as opposed to just stalling and incrementing the cycle count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59759 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Treat mid-block labels the same as terminators when building theDan Gohman
MachineInstr scheduling DAG, meaning they implicitly depend on all preceding defs. This fixes Benchmarks/Shootout-C++/except and Regression/C++/EH/simple_rethrow in -relocation-model=pic -disable-post-RA-scheduler=false mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59747 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Add another machine-code printing pass when post-pass scheduling is run.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59746 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-20Remove a remnant of list-burr's fast mode.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59702 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Factor out the SethiUllman numbering logic from the list-burr andDan Gohman
list-tdrr schedulers into a common base class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59701 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Remove the "fast" form of the list-burr scheduler, and use theDan Gohman
dedicated "fast" scheduler in -fast mode instead, which is faster. This speeds up llc -fast by a few percent on some testcases -- the speedup only happens for code not handled by fast-isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59700 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Facter AddPseudoTwoAddrDeps and associated infrasructure out ofDan Gohman

2008-11-20- Register scavenger should use MachineRegisterInfo and internal map to find ↵Evan Cheng
the first use of a register after a given machine instruction. - When scavenging a register, in addition to the spill, insert a restore before the first use. - Abort if client is looking to scavenge a register even when a previously scavenged register is still live. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59697 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19Simplify this code a little. In the fast scheduler, CreateNewSUnitDan Gohman
and CreateClone don't add any extra value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59679 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Experimental post-pass scheduling support. Post-pass schedulingDan Gohman
is currently off by default, and can be enabled with -disable-post-RA-scheduler=false. This doesn't have a significant impact on most code yet because it doesn't yet do anything to address anti-dependencies and it doesn't attempt to disambiguate memory references. Also, several popular targets don't have pipeline descriptions yet. The majority of the changes here are splitting the SelectionDAG-specific code out of ScheduleDAG, so that ScheduleDAG can be moved to libLLVMCodeGen.a. The interface between ScheduleDAG-using code and the rest of the scheduling code is somewhat rough and will evolve. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59676 91177308-0d34-0410-b5e6-96231b3b80d8
