Chris Lattner a43b832f7f Switch to the new shared SwitchSection 
llvm-svn: 24450
 2005-11-21 07:30:28 +00:00
Chris Lattner 2bccd73dbb Start using SwitchSection, allowing globals and functions to be emitted 
to specific sections.  Delete some dead functions copied from the X86 backend.

llvm-svn: 24449
 2005-11-21 07:26:04 +00:00
Chris Lattner 050bf2faf8 convert the rest of this over to use SwitchSection

 2005-11-21 07:16:34 +00:00
Chris Lattner 024e32e118 Start using the AsmPrinter shared SwitchSection code. This allows the X86 
backend to implement global variables in sections.

llvm-svn: 24447
 2005-11-21 07:11:11 +00:00
Chris Lattner b650241f8b This is now implemented in common codegen code 
llvm-svn: 24446
 2005-11-21 07:06:58 +00:00
Chris Lattner 2c0b435ba6 Rename SwitchSection -> switchSection to avoid conflicting with a future 
change.

llvm-svn: 24443
 2005-11-21 06:55:27 +00:00
Chris Lattner 8a4995e42a Start using PrivateGlobalPrefix correctly 
llvm-svn: 24442
 2005-11-21 06:51:52 +00:00
Chris Lattner 41cb115afb set PrivateGlobalPrefix on darwin, use it when printing out CP references 
llvm-svn: 24441
 2005-11-21 06:47:58 +00:00
Chris Lattner 618981fd03 Naturally align doubles in the constant pool, set PrivateGlobalPrefix on 
darwin, use it when printing the constant pool indices so the labels are
appropriately private, emit cp entries to .const instead of .data on darwin
and only emit a single .section for the constant pool, not one for each
entry.

llvm-svn: 24440
 2005-11-21 06:46:22 +00:00
Chris Lattner 6c1ca888d4 Lower READCYCLECOUNTER correctly, preserving the chain result

llvm-svn: 24406
 2005-11-18 01:04:42 +00:00
Nate Begeman 227f1bdd2f Also add the new vector value type here, for completeness. 
llvm-svn: 24405
 2005-11-18 00:53:32 +00:00
Chris Lattner cdde9990b7 only use dyld stubs if not in ppc-static mode. This completes support for 
non-static codegen.

llvm-svn: 24403
 2005-11-17 19:40:30 +00:00
Chris Lattner 6ab87fa360 refactor call operand handling to eliminate special cases from printOp. 
llvm-svn: 24401
 2005-11-17 19:25:59 +00:00
Chris Lattner bd9efdb64c disentangle call operands from branch operands a bit 
llvm-svn: 24400
 2005-11-17 19:16:08 +00:00
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.

llvm-svn: 24399
 2005-11-17 18:55:48 +00:00
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.

llvm-svn: 24397
 2005-11-17 18:26:56 +00:00
Chris Lattner 0fe88e3f32 Teach the selector to fold lo(g) into load instruction immediate fields 
llvm-svn: 24396
 2005-11-17 18:02:16 +00:00
Chris Lattner 4b11fa284d Generate LA and ADDIS when possible. 
llvm-svn: 24395
 2005-11-17 17:52:01 +00:00
Chris Lattner 3648c20472 Use the right accessor to create this node 
llvm-svn: 24394
 2005-11-17 17:51:38 +00:00
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.

 2005-11-17 07:30:41 +00:00
Chris Lattner 840458276c Add globaladdress and targetglobaladdress nodes for dag patterns 
llvm-svn: 24389
 2005-11-17 07:20:15 +00:00
Chris Lattner 63ed749ce0 LI could theoretically be used for the lo-part of a global address, just like 
lis can be used for the high part.

llvm-svn: 24388
 2005-11-17 07:04:43 +00:00
Chris Lattner b7025749e1 When lowering direct calls, lower them to use a targetglobaladress directly 
instead of a globaladdress.  This has no effect on the generated code at all.

which branches to an absolute address.  This is required to support objc
direct dispatch.

Duraid Madina f221c261f3 DAG->DAG instruction selection for ia64! "hello world" works, not much else. 
use -enable-ia64-dag-isel to turn this on

TODO: delete lowering stuff from the pattern isel
    : get operations on predicate bits working
    : get other bits of pseudocode going
    : use sampo's mulh/mull-using divide-by-constant magic
    : *so* many patterns ("extr", "tbit" and "dep" will be fun :)
    : add FP
    : add a JIT!
    : get it working 100%

in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.

OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.

Chris Lattner dae96f8881 When preselecting, favor things that have low depth to select first. This

required 8512 bytes of stack space for each invocation (GCC 3 required less
than 700 bytes).  Pulling this first function out gets us down to 8224.  More

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 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).

Chris Lattner 712e78ee28 Fix a problem that Nate noticed, where spill code was not getting coallesced 
with copies, leading to code like this:

       lwz r4, 380(r1)
       or r10, r4, r4    ;; Last use of r4

By teaching the PPC backend how to fold spills into copies, we now get this
code:

       lwz r10, 380(r1)

wow. :)

This reduces a testcase nate sent me from 1505 instructions to 1484.

Note that this could handle FP values but doesn't currently, for reasons
mentioned in the patch

Chris Lattner 39b4d83f6a Introduce two new concepts: 
1. Add support for defining Pattern's, which can match expressions when there
   is no instruction that directly implements something.  Instructions usually
   implicitly define patterns.
2. Add support for defining SDNodeXForm's, which are node transformations.
   This seperates the concept of a node xform out from the existing predicate
   support.

Using this new stuff, we add a few instruction patterns, one for testing, and
two for OR/XOR by an arbitrary immediate.

Chris Lattner a305d28cf6 Implement dynamic allocas correctly. In particular, because we were copying 
directly out of R1 (without using a CopyFromReg, which uses a chain), multiple
allocas were getting CSE'd together, producing bogus code.  For this:

int %foo(bool %X, int %A, int %B) {
        br bool %X, label %T, label %F
F:
        %G = alloca int
        %H = alloca int
        store int %A, int* %G
        store int %B, int* %H
        %R = load int* %G
        ret int %R
T:
        ret int 0
}

We were generating:

_foo:
        stwu r1, -16(r1)
        stw r31, 4(r1)
        or r31, r1, r1
        stw r1, 12(r31)
        cmpwi cr0, r3, 0
        bne cr0, .LBB_foo_2     ; T
.LBB_foo_1:     ; F
        li r2, 16
        subf r2, r2, r1   ;; One alloca
        or r1, r2, r2
        or r3, r1, r1
        or r1, r2, r2
        or r2, r1, r1
        stw r4, 0(r3)
        stw r5, 0(r2)
        lwz r3, 0(r3)
        lwz r1, 12(r31)
        lwz r31, 4(r31)
        lwz r1, 0(r1)
        blr
.LBB_foo_2:     ; T
        li r3, 0
        lwz r1, 12(r31)
        lwz r31, 4(r31)
        lwz r1, 0(r1)
        blr

Now we generate:

_foo:
        stwu r1, -16(r1)
        stw r31, 4(r1)
        or r31, r1, r1
        stw r1, 12(r31)
        cmpwi cr0, r3, 0
        bne cr0, .LBB_foo_2     ; T
.LBB_foo_1:     ; F
        or r2, r1, r1
        li r3, 16
        subf r2, r3, r2  ;; Alloca 1
        or r1, r2, r2
        or r2, r1, r1
        or r6, r1, r1
        subf r3, r3, r6  ;; Alloca 2
        or r1, r3, r3
        or r3, r1, r1
        stw r4, 0(r2)
        stw r5, 0(r3)
        lwz r3, 0(r2)
        lwz r1, 12(r31)
        lwz r31, 4(r31)
        lwz r1, 0(r1)
        blr
.LBB_foo_2:     ; T
        li r3, 0
        lwz r1, 12(r31)
        lwz r31, 4(r31)
        lwz r1, 0(r1)
        blr

This fixes Povray and SPASS with the dag isel, the last two failing cases.
