Chris Lattner c9ad735e78 add support for literal immediates in patterns to match, allowing us to 
write things like this:

def : Pat<(add GPRC:$in, 12),
          (ADD12 GPRC:$in)>;

llvm-svn: 23816

Chris Lattner b8014e10ae Add support for patterns that have physical registers in them. Testcase: 
def : Pat<(trunc G8RC:$in),
          (OR8To4 G8RC:$in, X0)>;

Even though this doesn't make any sense on PPC :)

Chris Lattner 8baf5043a8 Nate wants to define 'Pat's which turn into instructions that don't have 
patterns.  Certainly a logical request.

SelectNodeTo instead of getTargetNode when possible.

Chris Lattner 6b22d2554a Implement the last major missing piece in the DAG isel generator: when emitting 
a pattern match, make sure to emit the (minimal number of) type checks that
verify the pattern matches this specific instruction.  This allows FMA32
patterns to not match double expressions for example.

llvm-svn: 23748

Chris Lattner c4db8f4163 Now that we have int/fp lattice values, implement the SDTCisOpSmallerThanOp 
type constraint.  This lets tblgen realize that it doesn't need any dynamic
type checks for fextend/fround on PPC (and many other targets), because there
are only two fp types.

llvm-svn: 23730
 2005-10-14 06:25:00 +00:00
Chris Lattner ecaf56b21a Fairly serious rework of the typing code to add new int/fp lattice values. 
Overall, no functionality change yet though.

llvm-svn: 23725
 2005-10-14 04:53:53 +00:00
Chris Lattner 7b0275ba8c Implement a couple of new (important) features. 
1. If an operation has to be int or fp and the target only supports one
   int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
   for patterns involving those operators, since we do not emit the code to
   check for them yet.  This prevents PPC from generating FP ops currently.

Also move some code around into more logical places.

llvm-svn: 23529
 2005-09-29 22:36:54 +00:00
Chris Lattner e86824e57a Teach tblgen to build permutations of instructions, so that the target author 
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

Chris Lattner 8bb25cd68a Emit an error if instructions or patterns are defined but can never match. 
Currently we check that immediate values live on the RHS of commutative
operators.  Defining ORI like this, for example:

def ORI   : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
                    "ori $dst, $src1, $src2",
                    [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;

results in:

tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators!

Inst pattern EQV:       (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))

we now fully infer:

Inst pattern EQV:       (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

Reid Spencer dfb3fb4a25 Implement PR614: 
These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they

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.

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.

llvm-svn: 19760
 2005-01-22 20:31:17 +00:00
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

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.

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
}
