Chris Lattner 02884fe41c implement support for 64-bit add/sub, fix a broken assertion for 64-bit 
return.  Allow the udiv breaker-upper to work with any non-zero constant
operand.

Chris Lattner 6e184f2b3d Finish implementing SDIV/UDIV by copying over the majik constant code from 
ISelPattern

Chris Lattner b746dd1cf6 Implement setcc correctly for G5 and non-G5 systems 
llvm-svn: 23060
 2005-08-25 21:39:42 +00:00
Chris Lattner 3dcd75bc54 implement setcc on the G5. We're still missing the non-g5 specific bits, but 
they will come later.

Chris Lattner dc66457022 Add support for sdiv by 2^k and -2^k. Producing code like: 
_test:
        srawi r2, r3, 2
        addze r3, r2
        blr

Chris Lattner 25db699671 Implement support for taking the address of constant pool indices, which 
is used by the int -> FP code among other things.  This gets
2005-05-12-Int64ToFP past that failure, to dying on lack of support for add_parts

around to functions and stuff

Chris Lattner a3fbdae515 Split IMPLICIT_DEF into IMPLICIT_DEF_GPR and IMPLICIT_DEF_FP, so that the 
instructions take a consistent reg class.  Implement ISD::UNDEF in the dag->dag
selector to generate this, fixing UnitTests/2003-07-06-IntOverflow.

Nate Begeman a1e0a2f72b Remove unused statistic 
Prefer 'neg X' to 'subfic 0, X' since neg does not set XER[CA]

Chris Lattner 1d634b2f44 Fix compilation of: 
float %test2(float* %P) {
        %Q = load float* %P
        %R = add float %Q, %Q
        ret float %R
}

By returning the right result.

Nate Begeman d32638706a Improve ISD::Constant codegen. 
Now for int foo() { return -1; } we generate:
_foo:
        li r3, -1
        blr

instead of
_foo:
        lis r2, -1
        ori r3, r2, 65535
        blr

Nate Begeman 3fcf47d8f0 Teach the DAG->DAG ISel about FNEG, and how it can be used to invert 
several of the PowerPC opcodes that come in both negated and non-negated
forms.

 2005-08-17 23:46:35 +00:00
Chris Lattner 43ff01e2e6 initial hack at a dag->dag instruction selector. This is obviously woefully 
incomplete, but it is a start.  It handles basic argument/retval stuff, immediates,
add and sub.
