Evan Cheng c1163d2fa7 Remove an unneeded match condition: the type check for root node has been
moved to outside the actual select routine.

2006-07-31 19:01:58 +00:00
Evan Cheng 149130ad6b Split each select function for a particular opcode into multiple ones. One
per possible ValueType of the node. e.g. Select_add is split into Select_add_i8,
Select_add_i16, etc.

For opcodes which do not produce a non-chain result, it is split on the
ValueType of its first non-chain operand. e.g. Select_store.

On X86 / Mac OS X, Select_store used to be the largest function. It had a stack
frame size of 8.5k. Now the largest one is Store_i32 with a frame size of 3.1k.

Chris Lattner edee52570c Maximally group commands. When all instructions within a command set have a

llvm-svn: 29160
2006-07-16 06:12:52 +00:00
Evan Cheng 69367fedd2 Reduce instruction selection code size and stack frame size by factoring
code that emit target specific nodes into emit functions that are uniquified
and shared among selection routines.
e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame
size of Select_store from ~13k down to ~8k.
This is the first step. Further work to enable more sharing will follow.

2006-07-14 23:14:02 +00:00
Chris Lattner e32982cc52 Emit the string information for the asm writer as a single large string
and index into it, instead of emitting it like this:

  static const char * const OpStrs[] = {
    "PHINODE\n",        // PHI
    0,  // INLINEASM
    "adc ",     // ADC32mi
    "adc ",     // ADC32mi8
   ...

The old way required thousands of relocations that slows down link time and
dynamic load times.

This also cuts about 10K off each of the X86 asmprinters, and should shrink
the others as well.

Chris Lattner c23e641055 Don't require src/dst patterns to be able to fully resolve their types,
because information about one can help refine the other.  This allows us to
write:

def : Pat<(i32 (extload xaddr:$src, i8)),
          (LBZX xaddr:$src)>;

as:

def : Pat<(extload xaddr:$src, i8),
          (LBZX xaddr:$src)>;

because tblgen knows LBZX returns i32.

Chris Lattner 9500b343db Make sure to use the result of the pattern to infer the result type of the
instruction, and the result type of the instruction to refine the pattern.
This allows us to write things like this:

def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (v2i64 VR128:$src)>;

as:
def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)>

and fixes a ppc64 issue.

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.

Evan Cheng cc8c0233b6 Can't trust NodeDepth when checking for possibility of load folding creating
a cycle. This increase the search space and will increase compile time (in

Evan Cheng 886e8f35aa Now that iPTR is a fully resolved type. We end up losing the type check for
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

Chris Lattner c8565ed651 Change approach so that we get codegen for free for intrinsics. With this,
intrinsics that don't take pointer arguments now work.  For example, we can
compile this:

int test3( __m128d *A) {
  return _mm_movemask_pd(*A);
}
int test4( __m128 *A) {
  return _mm_movemask_ps(*A);
}

to this:

_test3:
        movl 4(%esp), %eax
        movapd (%eax), %xmm0
        movmskpd %xmm0, %eax
        ret
_test4:

Evan Cheng 368f20e53d Allow more loads to be folded which were previously prevented from happening
due to ordering issue. i.e. they were selected for chain use first.
Now at load select time, check if it is being selected for a chain use and if
it has only a single real use. If so, return a HANDLENODE (with the load as
its operand) in its place and record it.
When it is folded or the load is selected for a real use, the isel records it
as the replacement for the HANDLENODE. The replacement is done when all nodes
are selected.
This scheme exposed a couple of problems where cycles can happen. (See comments
in EmitMatchCode() for descriptions of the problems and their workaround /
solutions.) These problems have been resolved with a small compile time
penality.

2006-02-03 18:06:02 +00:00
Evan Cheng 717db484a5 (store (op (load ...))) folding problem. In the generated matching code,
Chain is initially set to the chain operand of store node, when it reaches
load, if it matches the load then Chain is set to the chain operand of the
load.

However, if the matching code that follows this fails, isel moves on to the
next pattern but it does not restore Chain to the chain operand of the store.
So when it tries to match the next store / op / load pattern it would fail on
the Chain == load.getOperand(0) test.

The solution is for each chain operand to get a unique name. e.g. Chain10.

node has two uses, when it is selected for one of the uses it is replaced with

Evan Cheng a15731cd50 Use pattern information to determine whether the use expects this
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.

Evan Cheng 14c53b45f5 Added field noResults to Instruction.
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

Chris Lattner 777bb6eb45 This ugly patch works around a GCC bug where it is compiling SelectCode to
use too much stack space, overflowing the stack for large functions.  Instead
of emitting new SDOperands in each match block, we emit some common ones at
the top of SelectCode then reuse them when possible.

This reduces the stack size of SelectCode from 28K to 21K.  Note that GCC
compiles it to 512 bytes :-/

llvm-svn: 24680
2005-12-12 23:45:21 +00:00
Evan Cheng 7e4c01eee3 At top of generated isel SelectCode() is this:
if (!N.Val->hasOneUse()) {
    std::map<SDOperand, SDOperand>::iterator CGMI = CodeGenMap.find(N);
    if (CGMI != CodeGenMap.end()) return CGMI->second;
  }

Suppose a DAG like this:

           X
         ^   ^
        /     \
      USE1    USE2

Suppose USE1 is being selected first and during which X is selected and
returned a new node. After this, USE1 is no longer an use of X. During USE2
selection, X will be selected again since it has only one use!

The fix is to always query CodeGenMap.

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.

Chris Lattner e86824e57a Teach tblgen to build permutations of instructions, so that the target author

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

                    "ori $dst, $src1, $src2",
                    [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;

results in:

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
}
