Chris Lattner 83e4407379 Don't create SEXTLOAD/ZEXTLOAD instructions that the target doesn't support 
if after legalize.  This fixes IA64 failures.

Nate Begeman 808f7a8abb Remove a now unused statistic. 
llvm-svn: 24720
 2005-12-14 22:56:16 +00:00
Nate Begeman e37cb604c1 Use the new predicate support that Evan Cheng added to remove some code 
from the DAGToDAG cpp file.  This adds pattern support for vector and
scalar fma, which passes test/Regression/CodeGen/PowerPC/fma.ll, and
does the right thing in the presence of -disable-excess-fp-precision.

Allows us to match:
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = mul <4 x float> %tmp1, %tmp1
  %tmp3 = add <4 x float> %tmp2, %tmp1
  store <4 x float> %tmp3, <4 x float> *%a
  ret void
}

As:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vmaddfp v0, v0, v0, v0
        stvx v0, r2, r3
        blr

Or, with llc -disable-excess-fp-precision,

_foo:
        li r2, 0
        lvx v0, r2, r3
        vxor v1, v1, v1
        vmaddfp v1, v0, v0, v1
        vaddfp v0, v1, v0
        stvx v0, r2, r3
        blr

llvm-svn: 24714
 2005-12-14 22:01:07 +00:00
Evan Cheng b8be9d1596 Fixed extload type profile. The 4th operand is a ValueType node with type 
OtherVT, it cannot be compare to type of 1st operand which is an integer type.

Chris Lattner d39c60fcc8 When folding loads into ops, immediately replace uses of the op with the 
load.  This reduces number of worklist iterations and avoid missing optimizations
depending on folding of things into sext_inreg nodes (which aren't supported by
all targets).
Tested by Regression/CodeGen/X86/extend.ll:test2

Reid Spencer 4c10e7643f Remove -start-group and -end-group no-op options, accidentally committed 
in last patch.

 2005-12-14 19:08:51 +00:00
Chris Lattner 7dac1083da Fix the (zext (zextload)) case to trigger, similarly for sign extends. 
Allow (zext (truncate)) to apply after legalize if the target supports
AND (which all do).

This compiles
short %foo() {
        %tmp.0 = load ubyte* %X         ; <ubyte> [#uses=1]
        %tmp.3 = cast ubyte %tmp.0 to short             ; <short> [#uses=1]
        ret short %tmp.3
}

to:
_foo:
        movzbl _X, %eax
        ret

instead of:

_foo:
        movzbl _X, %eax
        movzbl %al, %eax
        ret

thanks to Evan for pointing this out.

Reid Spencer 6796b48e51 Adjust the constructor to the Linker class to take an argument that names 
the module being constructed. This is used to correctly name the module.
Previously the name of the linker tool was used which produces confusing
output when the module identifier is used in an error message.

Reid Spencer 175613adf6 Improve ResolveFunctions to: 
a) use better local variable names (OldMT -> OldFT) where "M" is used to
   mean "Function" (perhaps it was previously "Method"?)
b) print out the module identifier in a warning message so that it is
   possible to track down in which module the error occurred.
