      Make the implicit inputs and outputs of target-independent · 0b8ca792
      Dale Johannesen authored
      ADDC/ADDE use MVT::i1 (later, whatever it gets legalized to)
      instead of MVT::Flag.  Remove CARRY_FALSE in favor of 0; adjust
      all target-independent code to use this format.
      
      Most targets will still produce a Flag-setting target-dependent
      version when selection is done.  X86 is converted to use i32
      instead, which means TableGen needs to produce different code
      in xxxGenDAGISel.inc.  This keys off the new supportsHasI1 bit
      in xxxInstrInfo, currently set only for X86; in principle this
      is temporary and should go away when all other targets have
      been converted.  All relevant X86 instruction patterns are
      modified to represent setting and using EFLAGS explicitly.  The
      same can be done on other targets.
      
      The immediate behavior change is that an ADC/ADD pair are no
      longer tightly coupled in the X86 scheduler; they can be
      separated by instructions that don't clobber the flags (MOV).
      I will soon add some peephole optimizations based on using
      other instructions that set the flags to feed into ADC.

      Wrap MVT::ValueType in a struct to get type safety · 13237ac3

      and better control the abstraction.  Rename the type
      to MVT.  To update out-of-tree patches, the main
      thing to do is to rename MVT::ValueType to MVT, and
      rewrite expressions like MVT::getSizeInBits(VT) in
      the form VT.getSizeInBits().  Use VT.getSimpleVT()
      to extract a MVT::SimpleValueType for use in switch
      statements (you will get an assert failure if VT is
      an extended value type - these shouldn't exist after
      type legalization).
      This results in a small speedup of codegen and no
      new testsuite failures (x86-64 linux).

      Move instruction flag inference out of InstrInfoEmitter and into · fc4ad7de
      Dan Gohman authored
      CodeGenDAGPatterns, where it can be used in other tablegen backends.
      This allows the inference to be done for DAGISelEmitter so that it
      gets accurate mayLoad/mayStore/isSimpleLoad flags. 
      
      This brings MemOperand functionality back to where it was before
      48329. However, it doesn't solve the problem of anonymous patterns
      which expand to code that does loads or stores.

      Allow ComplexExpressions in InstrInfo.td files to be slightly more... complex!... · 0592cf7e
      Christopher Lamb authored
      Allow ComplexExpressions in InstrInfo.td files to be slightly more... complex! ComplexExpressions can now have attributes which affect how TableGen interprets
      the pattern when generating matchin code. 
      
      The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern.

      Change the 'isStore' inferrer to look for 'SDNPMayStore' · a348f55e
      Chris Lattner authored
      instead of "ISD::STORE".  This allows us to mark target-specific dag
      nodes as storing (such as ppc byteswap stores).  This allows us to remove
      more explicit isStore flags from the .td files.
      
      Finally, add a warning for when a .td file contains an explicit 
      isStore and tblgen is able to infer it.
