Nate Begeman 4f229d5197 Add support for a TODO; instructions in .td files can now have arguments
printed as part of the opcode.  This allows something like
cmp${cc}ss in the x86 backed to be printed as cmpltss, cmpless, etc.
depending on what the value of $cc is.

Chris Lattner ef94374a1c Major change to tblgen: instead of resolving values every time a class is
finished up, only resolve fully when the def is defined.  This allows things
to be changed and all uses to be propagated through.  This implements
TableGen/LazyChange.td and fixes TemplateArgRename.td in the process.

None of the .td files used in LLVM backends are changed at all by this
patch.

Chris Lattner 59a7f5c2f3 This is the final big of factoring. This shares cases in suboperand
differences, which means that identical instructions (after stripping off
the first literal string) do not run any different code at all.  On the X86,
this turns this code:

    switch (MI->getOpcode()) {
    case X86::ADC32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADC32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADD32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::AND32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::OR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ROL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::ROR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SAR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SBB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::SHL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHLD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SHR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHRD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SUB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST8mi: printOperand(MI, 4, MVT::i8); break;
    case X86::XCHG32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    }

into this:

    switch (MI->getOpcode()) {
    case X86::ADC32mi:
    case X86::ADC32mr:
    case X86::ADD32mi:
    case X86::ADD32mr:
    case X86::AND32mi:
    case X86::AND32mr:
    case X86::CMP32mi:
    case X86::CMP32mr:
    case X86::MOV32mi:
    case X86::MOV32mr:
    case X86::OR32mi:
    case X86::OR32mr:
    case X86::SBB32mi:
    case X86::SBB32mr:
    case X86::SHLD32mrCL:
    case X86::SHRD32mrCL:
    case X86::SUB32mi:
    case X86::SUB32mr:
    case X86::TEST32mi:
    case X86::TEST32mr:
    case X86::XCHG32mr:
    case X86::XOR32mi:
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8:
    case X86::ADD32mi8:
    case X86::AND32mi8:
    case X86::OR32mi8:
    case X86::ROL32mi:
    case X86::ROR32mi:
    case X86::SAR32mi:
    case X86::SBB32mi8:
    case X86::SHL32mi:
    case X86::SHR32mi:
    case X86::SUB32mi8:
    case X86::TEST8mi:
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    }

After this, the generated asmwriters look pretty much as though they were
generated by hand.  This shrinks the X86 asmwriter.inc files from 55101->39669
and 55429->39551 bytes each, and PPC from 16766->12859 bytes.

Chris Lattner 92275bb6bb Implement *even more* factoring. In particular, if all of the instruction
strings starts out with a constant string, we emit the string first, using
a table lookup (instead of a switch statement).

Because this is usually the opcode portion of the asm string, the differences
between the instructions have now been greatly reduced.  This allows many
more case statements to be grouped together.

This patch also allows instruction cases to be grouped together when the
instruction patterns are exactly identical (common after the opcode string
has been ripped off), and when the differing operand is a MachineInstr
operand that needs to be formatted.

The end result of this is a mean and lean generated AsmPrinter!

Chris Lattner 9ceb7c8f23 Implement factoring of instruction pattern strings. In particular, instead of
emitting code like this:

  case PPC::ADD: O  << "add ";  printOperand(MI, 0, MVT::i64); O  << ", ";  prin
tOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '\n
'; break;
  case PPC::ADDC: O  << "addc ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
  case PPC::ADDE: O  << "adde ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
...

Emit code like this:

  case PPC::ADD:
  case PPC::ADDC:
  case PPC::ADDE:
  ...
    switch (MI->getOpcode()) {
    case PPC::ADD: O << "add "; break;
    case PPC::ADDC: O << "addc "; break;
    case PPC::ADDE: O << "adde "; break;
    ...
    }
    printOperand(MI, 0, MVT::i64);
    O << ", ";
    printOperand(MI, 1, MVT::i64);
    O << ", ";
    printOperand(MI, 2, MVT::i64);
    O << "\n";
    break;

This shrinks the PPC asm writer from 24785->15205 bytes (even though the new
asmwriter has much more whitespace than the old one), and the X86 printers shrink
quite a bit too.  The important implication of this is that GCC no longer hits swap
when building the PPC backend in optimized mode.  Thus this fixes PR448.

Chris Lattner 0c23ba5c0f Seperate asmstring parsing from emission. This allows the code to be simpler
and more understandable.  It also allows us to do simple things like fold
consequtive literal strings together.  For example, instead of emitting this
for the X86 backend:

  O  << "adc" << "l" << " ";

we now generate this:

  O << "adcl ";

*whoa* :)

This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

Chris Lattner 8bf9e06ddd Add initial support for list slices. This currently allows you to do stuff
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.

John Criswell 38a47ab007 Removed the .PRECIOUS of Lex and Yacc output files.
They are already marked precious in llvm/Makefile.rules, and removing
this line seems to fix the Makefile so that the Yacc output is placed
into the object tree and not the source tree.

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
}
