Nate Begeman 4e56db674c Add support for TargetConstantPool nodes to the dag isel emitter, and use
them in the PPC backend, to simplify some logic out of Select and
SelectAddr.

Chris Lattner fea33f7e64 Use new PPC-specific nodes to represent shifts which require the 6-bit
amount handling that PPC provides.  These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits.  This fixes a miscompilation of crafty with
the new front-end.

llvm-svn: 24615
2005-12-06 02:10:38 +00:00
Chris Lattner f3322af5c6 Add some explicit type casts so that tblgen knows the type of the shift
amount, which is not necessarily the same as the type being shifted.

Nate Begeman 6f8c1ace6e No longer track value types for asm printer operands, and remove them as

Nate Begeman 1064d6ec43 First chunk of actually generating vector code for packed types. These
changes allow us to generate the following code:

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

for this llvm:

void %foo(<4 x float>* %a) {
entry:
        %tmp1 = load <4 x float>* %a
        %tmp2 = add <4 x float> %tmp1, %tmp1
        store <4 x float> %tmp2, <4 x float>* %a
        ret void
}

Nate Begeman c138118cdb Add the remainder of the AltiVec 4 x float instructions. Further

Chris Lattner 7a18a25d33 don't say this is i128, because it isn't yet. Hopefully nate will change
this to be something sane, but in the mean time it is unused, so safe to
make something bogus.

Nate Begeman 8492fd30ab Some first bits of AltiVec stuff: Instruction Formats, Encodings, and
Registers.  Apologies to Jim if the scheduling info so far isn't accurate.

There's a few more things like VRsave support that need to be finished up
in my local tree before I can commit code that Does The Right Thing for
turning 4 x float into the various altivec packed float instructions.

Chris Lattner 3570cf456b add an option to generate completely non-pic code, corresponding to what
gcc -static produces on PPC.  This is used for building kexts and other things.

With this, materializing the address of a global looks like:

        lis r2, ha16(L_H$non_lazy_ptr)
        la r3, lo16(L_H$non_lazy_ptr)(r2)

we're still emitting stubs for functions, which is wrong.  That is next.

Chris Lattner 8f8ed28a64 Fix a bug that resistor on IRC hit where we tried to create token factor
nodes of load results, not of their chain results.

llvm-svn: 24398
2005-11-17 18:30:17 +00:00
Chris Lattner 5aba6ae3b3 Enable global address legalization, fixing a todo and allowing the removal
of some code.  This exposes the implicit load from the stubs to the DAG, allowing
them to be optimized by the dag combiner.  It also moves darwin specific stuff
out of the isel into the legalizer, and allows more to be moved to the .td file.

Chris Lattner 595088aa0f Add an initial hack at legalizing GlobalAddress into the appropriate nodes
on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2

The obvious improvements will follow.

Chris Lattner b7025749e1 When lowering direct calls, lower them to use a targetglobaladress directly

Chris Lattner 5ab9d42bb4 Minor tweak to the branch selector. When emitting a two-way branch, and if
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch.  For example, emit this:

LBBl29_z__44:
        stw r9, 0(r15)
        stw r9, 4(r15)
        stw r9, 8(r15)
        stw r9, 12(r15)
        addi r15, r15, 16
        addi r8, r8, 1
        cmpw cr0, r8, r28
        ble cr0, LBBl29_z__44
        b LBBl29_z__48                   *** NOT PART OF LOOP

Instead of:

LBBl29_z__44:
        stw r9, 0(r15)
        stw r9, 4(r15)
        stw r9, 8(r15)
        stw r9, 12(r15)
        addi r15, r15, 16
        addi r8, r8, 1
        cmpw cr0, r8, r28
        bgt cr0, LBBl29_z__48            *** PART OF LOOP!
        b LBBl29_z__44

The former sequence has one fewer dispatch group for the loop body.

Chris Lattner 0f965a615e Change the arg lowering code to use copyfromreg from vregs associated
with incoming arguments instead of the pregs themselves.  This fixes
the scheduler from causing problems by moving a copyfromreg for an argument
to after a select_cc node (now it can, and bad things won't happen).

Chris Lattner 0f2146bb5d I forgot that we always spill fp values as 64-bits. Implement spill folding
for FP as well.  This triggers a couple dozen times on 177.mesa (for example).
