Bruno Cardoso Lopes b02a9dfa55 Negative zero is not legal on mips. Patch by Sasa Stankovic 
llvm-svn: 123766
 2011-01-18 19:41:41 +00:00
Bruno Cardoso Lopes ac517fa9f7 Handle (i32,i32) => f64 in a cleaner way. Patch by Sasa Stankovic

Bruno Cardoso Lopes 4dc73fa075 Add support for mips32 madd and msub instructions. Patch by Akira Hatanaka 
llvm-svn: 123760
 2011-01-18 19:29:17 +00:00
Chris Lattner 3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

Bruno Cardoso Lopes b9bfd0945a Remove target specific node MipsISD::CMov, which is not used because all conditional moves are directly matched using tablegen patterns. If there's a need in the future, we can introduce it again

Duncan Sands 71049f78ed In the calling convention logic, ValVT is always a legal type, 
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

Duncan Sands f5dda01f33 Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

John Thompson e8360b7182 Inline asm multiple alternative constraints development phase 2 - improved basic logic, added initial platform support.

Bruno Cardoso Lopes 160695fecb Fix PR7174, a couple o Mips fixes: 
- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

Dan Gohman fe7532a308 Split the SDValue out of OutputArg so that SelectionDAG-independent 
code can do calling-convention queries. This obviates OutputArgReg.

Devang Patel a3ca21b228 Propagate debug loc.

Dan Gohman 3439629239 Reapply r107655 with fixes; insert the pseudo instruction into 
the block before calling the expansion hook. And don't
put EFLAGS in a mbb's live-in list twice.

 2010-07-06 20:24:04 +00:00
Dan Gohman f4f04107ef Revert r107655. 
llvm-svn: 107668
 2010-07-06 15:49:48 +00:00
Dan Gohman 12205645a6 Fix a bunch of custom-inserter functions to handle the case where 
the pseudo instruction is not at the end of the block.

llvm-svn: 107655
 2010-07-06 15:18:19 +00:00
Evan Cheng 0664a67fe1 Remove isSS argument from CreateFixedObject. Fixed objects cannot be spill slots so it's always false. 
llvm-svn: 107550
 2010-07-03 00:40:23 +00:00
Dan Gohman 25c1653700 Get rid of the EdgeMapping map. Instead, just check for BasicBlock 
changes before doing phi lowering for switches.

llvm-svn: 102809
 2010-05-01 00:01:06 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

llvm-svn: 101635
 2010-04-17 15:26:15 +00:00
Dan Gohman 31ae586c74 Move per-function state out of TargetLowering subclasses and into 
MachineFunctionInfo subclasses.

llvm-svn: 101634
 2010-04-17 14:41:14 +00:00
Dan Gohman bcaf681cde Add const qualifiers to CodeGen's use of LLVM IR constructs. 
llvm-svn: 101334
 2010-04-15 01:51:59 +00:00
David Greene 3cd87cc5ee Remove an assumption of default arguments. This is in anticipation of a 
change to SelectionDAG build APIs.

Bruno Cardoso Lopes d59cddc098 Add suport for VASTART on Mips. 
llvm-svn: 95506
 2010-02-06 21:00:02 +00:00
Bruno Cardoso Lopes d6fff557db First step towards varargs support in Mips: 
- o32 cc must pass all arguments in A0...A3 and stack regardless
if its type (but respect the alignment).
- Store all variable arguments back to the caller stack.

Evan Cheng 6f36a083ef Revert 95130. 
llvm-svn: 95160
 2010-02-02 23:55:14 +00:00
Evan Cheng c1b0116ff1 Pass callsite return type to TargetLowering::LowerCall and use that to check sibcall eligibility. 
llvm-svn: 95130
 2010-02-02 21:29:10 +00:00
Bruno Cardoso Lopes 193e64c699 Fix PR6144. Reload GP before the emission of CALLSEQ_END to guarantee the right reload order 
llvm-svn: 94915
 2010-01-30 18:32:07 +00:00
Evan Cheng 67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization. 
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

llvm-svn: 94626
 2010-01-27 00:07:07 +00:00
Chris Lattner 547c761dd6 eliminate the TargetLowering::UsesGlobalOffsetTable bool, which is 
subsumed by TargetLowering::getJumpTableEncoding().  Change uses of
it to be more specific.

Bruno Cardoso Lopes 2db07581b7 Support PIC loading of constant pool entries 
llvm-svn: 89863
 2009-11-25 12:17:58 +00:00
Dan Gohman de5dea869f Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used. 
Note that "hasDotLocAndDotFile"-style debug info was already broken;
people wanting this functionality should implement it in the
AsmPrinter/DwarfWriter code.

llvm-svn: 89711
 2009-11-23 23:20:51 +00:00
Devang Patel ed85e12da6 We are not using DBG_STOPPOINT anymore. 
llvm-svn: 89536
 2009-11-21 02:46:55 +00:00
Bruno Cardoso Lopes 537e409c58 - Fix a small bug while handling target constant pools (one param was missing). 
- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)
lwc1 $f0, %lo($CPI1_0)($2)

 2009-11-16 04:33:42 +00:00
David Greene 1fbe054450 Add a bool flag to StackObjects telling whether they reference spill 
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..

llvm-svn: 87022
 2009-11-12 20:49:22 +00:00
Evan Cheng 83896a59e1 Add a second ValueType argument to isFPImmLegal. 
llvm-svn: 85361
 2009-10-28 01:43:28 +00:00
Evan Cheng 16993aa30b Do away with addLegalFPImmediate. Add a target hook isFPImmLegal which returns true if the fp immediate can be natively codegened by target. 
llvm-svn: 85281
 2009-10-27 19:56:55 +00:00
Evan Cheng 9827ad39a7 Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks. 
llvm-svn: 82311
 2009-09-19 09:51:03 +00:00
Evan Cheng 270d0f986f Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that sdisel will use to properly complete phi nodes. 
Not functionality change yet.

Bruno Cardoso Lopes 0f20a5b338 Reapply 80278 
Add MO flags to simplify the printing of relocations.
Remove the support for printing large code model relocs (which
aren't supported anyway).

llvm-svn: 80691
 2009-09-01 17:27:58 +00:00
Bruno Cardoso Lopes e91191630b Revert 80278 for now, it caused a lot of MIPS tests to fail

Bruno Cardoso Lopes 18c21daafb Revamp our friend Mips :)

 2009-08-27 19:40:40 +00:00
Chris Lattner 68535f7603 reintroduce support for Mips "small" section handling. This is 
implemented somewhat differently than before, but it should have
the same functionality and the previous testcase passes again.

llvm-svn: 78900
 2009-08-13 06:28:06 +00:00
Chris Lattner 58e8be847c Restore some "small section" support code, reverting my patch from r76936.

Owen Anderson 9f94459d24 Split EVT into MVT and EVT, the former representing _just_ a primitive type, while 
the latter is capable of representing either a primitive or an extended type.

llvm-svn: 78713
 2009-08-11 20:47:22 +00:00
Owen Anderson 53aa7a960c Rename MVT to EVT, in preparation for splitting SimpleValueType out into its own struct type. 
llvm-svn: 78610
 2009-08-10 22:56:29 +00:00
Owen Anderson c30530d105 Start moving TargetLowering away from using full MVTs and towards SimpleValueType, which will simplify the privatization of IntegerType in the future.
