Chris Lattner cfedba706c Fix a bug I introduced in the ppc refactoring, which caused long 
branches to be emitted as:

 	bne cr0, 2
instead of:
 	bne cr0, $+8

Chris Lattner 73716a600a relax an assertion a bit, allowing the GPR argument of 
these instructions to be encoded with getMachineOpValue.
This unbreaks ExecutionEngine/2003-01-04-ArgumentBug.ll

Chris Lattner aac9fa731d Wire up primitive support in the assembler backend for writing .o files 
directly on the mac.  This is very early, doesn't support relocations and
has a terrible hack to avoid .machine from being printed, but despite
that it generates an bitwise-identical-to-cctools .o file for stuff like 
this:

  define i32 @test() nounwind { ret i32 42 }

I don't plan to continue pushing this forward, but if anyone else was
interested in doing it, it should be really straight-forward.

Chris Lattner efacb9ee42 split out an encoder for memri operands, allowing a relocation to be plopped 
into the immediate field.  This allows us to encode stuff like this:

        lbz r3, lo16(__ZL4init)(r4)     ; globalopt.cpp:5
                                        ; encoding: [0x88,0x64,A,A]
                                        ;   fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16

        stw r3, lo16(__ZL1s)(r5)        ; globalopt.cpp:6
                                        ; encoding: [0x90,0x65,A,A]
                                        ;   fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16

With this, we should have a completely function MCCodeEmitter for PPC, wewt.

llvm-svn: 119134
 2010-11-15 08:22:03 +00:00
Chris Lattner 8f4444d003 add support for encoding the lo14 forms used for a few PPC64 addressing 
modes.  For example, we now get:

	ld r3, lo16(_G)(r3)             ; encoding: [0xe8,0x63,A,0bAAAAAA00]
                                        ;   fixup A - offset: 0, value: lo16(_G), kind: fixup_ppc_lo14

llvm-svn: 119133
 2010-11-15 08:02:41 +00:00
Chris Lattner 15e9d5ef8a fix a regression with the new instprinter: we lost the ability to 
print DBG_VALUE instructions.  This should unbreak the llvm-gcc-powerpc-darwin9
buildbot.

llvm-svn: 119132
 2010-11-15 07:52:06 +00:00
Chris Lattner 6566112e9c implement the start of support for lo16 and ha16, allowing us to get stuff like: 
lis r4, ha16(__ZL4init)         ; encoding: [0x3c,0x80,A,A]
                                        ;   fixup A - offset: 0, value: ha16(__ZL4init), kind: fixup_ppc_ha16

llvm-svn: 119127
 2010-11-15 06:33:39 +00:00
Chris Lattner 85e37684bf add a fixup for conditional branches, giving us output like this: 
beq cr0, LBB0_4                 ; encoding: [0x41,0x82,A,0bAAAAAA00]
                                        ;   fixup A - offset: 0, value: LBB0_4, kind: fixup_ppc_brcond14

llvm-svn: 119126
 2010-11-15 06:12:22 +00:00
Chris Lattner 0e3461e417 change direct branches to encode with the same encoding method 
as direct calls.  Change conditional branches to encode with
their own method, simplifying the JIT encoder and making room
for adding an mc fixup.

 2010-11-15 06:01:10 +00:00
Chris Lattner 79fa37152a split call operands out to their own encoding class, simplifying 
code in the JIT.  Use this to form the first fixup for the PPC backend,
giving us stuff like this:

	bl L_foo$stub ; encoding: [0b010010AA,A,A,0bAAAAAA01]
                                        ;   fixup A - offset: 0, value: L_foo$stub, kind: fixup_ppc_br24

 2010-11-15 05:19:25 +00:00
Chris Lattner c877d8f44c add basic encoding support for immediates and registers, allowing us 
to encode all of these instructions correctly (for example):

        mflr r0                         ; encoding: [0x7c,0x08,0x02,0xa6]
        stw r0, 8(r1)                   ; encoding: [0x90,0x01,0x00,0x08]
        stwu r1, -64(r1)                ; encoding: [0x94,0x21,0xff,0xc0]

Chris Lattner 9ec375c8ea Implement a basic MCCodeEmitter for PPC. This doesn't handle 
fixups yet, and doesn't handle actually encoding operand values,
but this is enough for llc -show-mc-encoding to show the base
instruction encoding information, e.g.:

	mflr r0                         ; encoding: [0x7c,0x08,0x02,0xa6]
	stw r0, 8(r1)                   ; encoding: [0x90,0x00,0x00,0x00]
	stwu r1, -64(r1)                ; encoding: [0x94,0x00,0x00,0x00]
Ltmp0:
	lhz r4, 4(r3)                   ; encoding: [0xa0,0x00,0x00,0x00]
	cmplwi cr0, r4, 8               ; encoding: [0x28,0x00,0x00,0x00]
	beq cr0, LBB0_2                 ; encoding: [0x40,0x00,0x00,0x00]

Chris Lattner aa4d03d1f5 remove asmstrings (which can never be printed) from pseudo 
instructions, allowing is to eliminate some dead operand 
printing methods from the instprinter.

Chris Lattner 510c66f549 rip out a ton of old instruction printing junk now that the 
new instprinting logic is there.

 2010-11-15 03:39:06 +00:00
Chris Lattner d7c2fc7a73 Turn on the new instprinter by default. 
The only change in the output is:

1) we get a better comment on mfcr, we get:
	mfcr r2                         ; cr2
  instead of:
 	mfcr r2 ; 32

2) we no longer emit $stub's on powerpc/leopard.  The Leopard
   linker autosynthesizes them.

llvm-svn: 119108
 2010-11-15 03:27:05 +00:00
Chris Lattner dd6df84900 convert the operand bits into bitfields since they are all combinable in 
different ways.  Add $non_lazy_ptr support, and proper lowering for
global values.

Now all the ppc regression tests pass with the new instruction printer.

llvm-svn: 119106
 2010-11-15 03:13:19 +00:00
Chris Lattner edb9d84dcc add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

Chris Lattner df8e17d80b implement support for the MO_DARWIN_STUB TargetOperand flag, 
and have isel apply to to call operands as required.  This allows
us to get $stub suffixes on label references on ppc/tiger with the
new instprinter, fixing two tests.  Only 2 to go.

Chris Lattner 7077efe894 move the pic base symbol stuff up to MachineFunction 
since it is trivial and will be shared between ppc and x86.
This substantially simplifies the X86 backend also.

Chris Lattner 94f0c14cb0 reimplement ppc asmprinter "toc" handling to use a VariantKind
