Evan Cheng e01ee43cdc Comments; getChain(), getBasePtr(), etc. should return a SDOperand by value.

Evan Cheng 16488647d8 shufps with load folding is better than movaps; movsd.

Evan Cheng 57ccb6d372 Don't go too crazy with these AddComplexity. Try matching shufps with load 
folding first.

Evan Cheng 75a1b70da8 Predicate function on the node should be matched before its childrean' matching 
code. This is especially important now matching ISD::LOAD also requires a
Predicate_Load call.

Evan Cheng e71fe34d75 Reflects ISD::LOAD / ISD::LOADX / LoadSDNode changes. 
llvm-svn: 30844
 2006-10-09 20:57:25 +00:00
Evan Cheng 0a2a4b1fbe Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes. 
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.

Reid Spencer ff35900383 Fix PR886: 
The result of yyparse() was not being checked. When YYERROR or YYABORT is
called it causes yyparse() to return 1 to indicate the error. The code was
silently ignoring this situation because it previously expected either an
exception or a null ParserResult to indicate an error. The patch corrects
this situation.

Chris Lattner 5ab6d8b3fc Eliminate more token factors by taking advantage of transitivity: 
if TF depends on A and B, and A depends on B, TF just needs to depend on
A.  With Jim's alias-analysis stuff enabled, this compiles the testcase in
PR892 into:

__Z4test3Val:
        subl $44, %esp
        call L__Z3foov$stub
        movl %edx, 28(%esp)
        movl %eax, 32(%esp)
        movl %eax, 24(%esp)
        movl %edx, 36(%esp)
        movl 52(%esp), %ecx
        movl %ecx, 4(%esp)
        movl %eax, 8(%esp)
        movl %edx, 12(%esp)
        movl 48(%esp), %eax
        movl %eax, (%esp)
        call L__Z3bar3ValS_$stub
        addl $44, %esp
        ret

instead of:

__Z4test3Val:
        subl $44, %esp
        call L__Z3foov$stub
        movl %eax, 24(%esp)
        movl %edx, 28(%esp)
        movl 24(%esp), %eax
        movl %eax, 32(%esp)
        movl 28(%esp), %eax
        movl %eax, 36(%esp)
        movl 32(%esp), %eax
        movl 36(%esp), %ecx
        movl 52(%esp), %edx

        movl %eax, 8(%esp)
        movl %ecx, 12(%esp)

Chris Lattner 398195ebbe completely disable folding of loads into scalar sse instructions and provide 
a framework for doing it right.  This fixes
CodeGen/X86/2006-10-07-ScalarSSEMiscompile.ll.

Once X86DAGToDAGISel::SelectScalarSSELoad is implemented right, this task
will be done.
