Evan Cheng 55772ccfd6 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

Chris Lattner db2a5f09f1 If we want to emit things in enum order, use getInstructionsByEnumValue to 
get the order, don't compute it ourselves.

Don't emit stuff like (14<<0), emit 14 instead.

Don't attempt to get target properties for builtin instructions.

Chris Lattner 96d0234845 Emit this: 
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, };

instead of this:

static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, };

For operand information, which does not require dynamic (startup-time)
initialization.

Chris Lattner d02bd5bb05 Emit real operand info for instructions. This currently works but is bad 
in one way: the generated tables require dynamic initialization for the
register classes.  This will be fixed in a future patch.

Chris Lattner 511ee687e5 now that all of the targets are clean w.r.t. the number of operands for each 
instruction defined, actually emit this to the InstrInfoDescriptor, which
allows an assert in the machineinstrbuilder to do some checking for us,
and is required by the dag->dag emitter

Chris Lattner b015303c5e revert this change, which causes breakage, temporarily 
llvm-svn: 22880
 2005-08-18 22:12:31 +00:00
Chris Lattner 99df668f48 When emitting implicit use/def lists, only emit each unique list once. Though 
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data.  This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.

This should speed up the register allocator as well by reducing the dcache
footprint for this static data.

Alkis Evlogimenos 5f1f337d95 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
