 2004-07-18 07:26:17 +00:00
Brian Gaeke 5ce1408537 Do IMPLICIT_DEFs on incoming args' hard regs, to avoid confusing the regalloc. 
Support single-fp incoming args.
Support single-fp outgoing args ('call' operands).
Support double-fp return values.

llvm-svn: 14880

llvm-svn: 14684
 2004-07-08 08:08:10 +00:00
Brian Gaeke dc5940794c Fix bug in copying long constants to register pairs. We were getting 
the top and bottom halves backwards...how embarrassing.
Support 'cast long to long' and other similar no-op casts to long.
Support 'ret long'.

llvm-svn: 14683
 2004-07-08 07:52:13 +00:00
Brian Gaeke 4ba31a2e1e Support 'ret float'

 2004-07-08 07:22:27 +00:00
Chris Lattner 0969646d6e Add #includes 
llvm-svn: 14625
 2004-07-04 17:19:21 +00:00
Misha Brukman b9125f462d Fix indentation to be 2 spaces. 
llvm-svn: 14512
 2004-06-30 22:11:03 +00:00
Misha Brukman 04f07b4589 visitSetCondInst() takes a parameter of type `SetCondInst' 
llvm-svn: 14508
 2004-06-30 21:47:40 +00:00
Brian Gaeke c81b5a5331 Trim whitespace. 
Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

llvm-svn: 14440
 2004-06-27 22:47:33 +00:00
Brian Gaeke 72490c8d86 Support cast float to float, cast double to float, and cast float to double. 
(It's not yet clear how to copy doubles from register to register.)

llvm-svn: 14371
 2004-06-24 21:22:08 +00:00
Brian Gaeke 2f6741f4f3 Fix a dyn_cast in copyConstantToRegister which should have been a cast. 
Compactify the code that emits copies of constant ints into registers.

llvm-svn: 14365
 2004-06-24 09:17:47 +00:00
Brian Gaeke 4ed2826ce5 Use correct add*Imm form in more BuildMI calls. 
Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.
(hey, wouldn't a constant expression lowering pass be cool? huh huhuhuh)
Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.

llvm-svn: 14363
 2004-06-24 08:55:09 +00:00
Brian Gaeke 9f455efff1 Rename the load and store opcodes. The non-fp ones only have one 
variant worth worrying about; the fp ones have two.
Stub out the case analysis of int-to-fp casts (no code yet).
I think the number of operands passed to BuildMI for loads was wrong.
Support load and store of float and double.

llvm-svn: 14360
 2004-06-24 07:36:48 +00:00
Brian Gaeke 8863de761d Strange as it may sound, we'll not use LDD/STD to store longs. For reasons of 
representational consistency, we want to address the halves of each 64-bit value
separately.

llvm-svn: 14356
 2004-06-24 06:44:57 +00:00
Brian Gaeke 1e8cc73ea3 Support constant cast expressions. 
llvm-svn: 14355
 2004-06-24 06:33:00 +00:00
Chris Lattner bcdadf3765 Move the IntrinsicLowering header into the CodeGen directory, as per PR346 
llvm-svn: 14266
 2004-06-20 07:49:54 +00:00
Brian Gaeke 694f7b78d9 Make visitAllocaInst() look more like its X86 counterpart. 
llvm-svn: 14229
 2004-06-18 08:45:52 +00:00
Brian Gaeke 5ebab28a8a Support intrinsic calls (although no particular intrinsics are supported yet). 
Support indirect calls.
Support returning a float value.

llvm-svn: 14223
 2004-06-18 06:27:48 +00:00
Brian Gaeke 21305c6f0c Support alloca instructions. 
Support copying floating-point constants to registers.
Add assertion to visitCallInst to abort if we hit a NULL calledFunction, for now.

llvm-svn: 14216
 2004-06-18 05:19:16 +00:00
Brian Gaeke c4ee938f55 Support generating machine instructions for Phi nodes (based on x86, but with 
modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

llvm-svn: 14208
 2004-06-17 22:34:08 +00:00
Brian Gaeke 2f2b5f5b93 Use addGlobalAddress and addMBB for call & branch targets instead of addPCDisp. 
Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.

llvm-svn: 14202
 2004-06-17 19:39:23 +00:00
Chris Lattner 6b7275996c Rename Type::PrimitiveID to TypeId and ::getPrimitiveID() to ::getTypeID() 
llvm-svn: 14201
 2004-06-17 18:19:28 +00:00
Brian Gaeke 476c73b241 Fix thinko in visitor... ShiftInsts should currently be delegated 
to visitBinaryOperator.

llvm-svn: 14182
 2004-06-15 21:09:46 +00:00
Brian Gaeke 0c8ee30d53 Fix bug generating code for void call instructions: don't call 
getReg() on void value.

llvm-svn: 14178
 2004-06-15 20:06:32 +00:00
Brian Gaeke 19fbd28a06 Support constant GEP expressions. 
Support copying long constants to register pairs.
Support copying ConstantPointerNulls and ConstantPointerRefs to registers.

llvm-svn: 14175
 2004-06-15 19:16:07 +00:00
Brian Gaeke 1096ba9422 Add support for widening integral casts. 
Flesh out the SetCC support... which currently ends in a little bit
of unfinished code (which is probably completely hilarious) for
generating the condition value splitting the basic block up into 4
blocks, like this (clearly a better API is needed for this!):

       BB
   cond. branch
     /         /          R1=1    R2=0
     \      /
      \    /
    R=phi(R1,R2)

Other minor edits.

llvm-svn: 13423
 2004-05-08 06:36:14 +00:00
Brian Gaeke 7a66e5fff9 Flesh out GEP support 
llvm-svn: 13421
 2004-05-08 05:27:20 +00:00
Brian Gaeke f3a479f04a Add stub support for GEPs. 
Add support for branches (based loosely on X86/InstSelectSimple).
Add support for not visiting phi nodes in the first pass.
Add support for loading bools.
Flesh out support for stores.

llvm-svn: 13418
 2004-05-08 04:21:17 +00:00
Brian Gaeke 584308b71a Add support for copying bool constants to registers. 
Disable the code that copies long constants to registers - it looks fishy.
Implement some simple casts: integral, smaller than longs, and equal-width
 or narrowing only.

llvm-svn: 13413
 2004-05-07 21:39:30 +00:00
Brian Gaeke 969795b4ea I started working on casts, but I don't have anything compilable yet. 
llvm-svn: 12903
 2004-04-13 18:27:46 +00:00
Brian Gaeke 6d62df5422 First version of code to handle loads. Stub function for handling stores. 
llvm-svn: 12758
 2004-04-07 17:29:37 +00:00
Brian Gaeke 989c04ab58 Support loading arguments from %I0...%I5 into virtual registers in 
function prologues, and fix an off-by-one in visitCallInst that was
putting call args into the wrong registers.

llvm-svn: 12757
 2004-04-07 17:04:09 +00:00
Brian Gaeke 7985e56cf9 It's setting up the call args right now, but on the callee side, it's 
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

llvm-svn: 12756
 2004-04-07 16:41:22 +00:00
Chris Lattner bd58b3fbe9 This is a start on handling setcc instructions. As the comment notes, we 
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

llvm-svn: 12745
 2004-04-07 05:04:51 +00:00
Chris Lattner f6245bc8e9 Avoid emitting an extra copy on each 32-bit operation 
llvm-svn: 12743
 2004-04-07 04:36:53 +00:00
Chris Lattner 42ffd2e32c Add support for shift instructions, wrap some long lines 
llvm-svn: 12740
 2004-04-07 04:27:16 +00:00
Chris Lattner fcdf82a19f Add a bunch more instructions 
llvm-svn: 12737
 2004-04-07 04:06:46 +00:00
Brian Gaeke cfbfb8ac57 Preliminary support for getting 64-bit integer constants into registers. 
Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.

llvm-svn: 12732
 2004-04-07 04:00:49 +00:00
Brian Gaeke 2e91a3d650 Deal with call return values. 
Don't put NOPs in delay slots at all. We'll have a fix-up pass later.

llvm-svn: 12725
 2004-04-06 22:09:23 +00:00
Brian Gaeke 2fd46b6e43 Add support for call instructions (0-ary only for now). 
llvm-svn: 12629
 2004-04-02 20:53:33 +00:00
Brian Gaeke 3fb0e203cd Fix bug in zero-extending of shorts. 
llvm-svn: 12453
 2004-03-16 22:45:42 +00:00
Brian Gaeke 67fcefbfef Make getClass more robust by adding cLong. 
Add handling for Mul instruction.

llvm-svn: 12450
 2004-03-16 22:37:11 +00:00
Brian Gaeke 3a27bd889b Hmm, who left this sitting around in my tree 
llvm-svn: 12255
 2004-03-09 04:49:13 +00:00
Brian Gaeke 4e0669cef0 Support return values of basic integer types. 
Emit RETL instruction to return instead of funny JMPL.
Fix indentation.

llvm-svn: 12186
 2004-03-06 05:32:28 +00:00
Brian Gaeke 92c95f812d Subtract instructions; minor cleanups 
llvm-svn: 12111
 2004-03-04 04:37:45 +00:00
Brian Gaeke 956fb06a4a Simple copyConstantToReg support, SETHIi and ORri 
llvm-svn: 12107
 2004-03-04 00:56:25 +00:00
Brian Gaeke 165ff998e0 Support add - note, still missing important copyConstantToRegister stuff 
llvm-svn: 12106
 2004-03-03 23:03:14 +00:00
Chris Lattner b1862e4d3b Add an instruction selector capable of selecting 'ret void'
