* Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel2011-02-211-1/+1
| | | | | | | | | | | LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) llvm-svn: 126155

* rename MVT::Flag to MVT::Glue. "Flag" is a terrible name forChris Lattner2010-12-211-1/+1
| | | | | | | something that just glues two nodes together, even if it is sometimes used for flags. llvm-svn: 122310

* Renaming ISD::BIT_CONVERT to ISD::BITCAST to better reflect the LLVM IR concept.Wesley Peck2010-11-231-92/+92
| | | | llvm-svn: 119990
* Fix a bug with extractelement on SPU.Kalle Raiskila2010-11-221-1/+1
| | | | | | | In the attached testcase, the element was never extracted (missing rotate). llvm-svn: 119973
* Improve code layout, mostly indentation. Kalle Raiskila2010-11-151-166/+150
| | | | | | No functionality change. llvm-svn: 119142
* Fix memory access lowering on SPU, addingKalle Raiskila2010-11-121-102/+219
| | | | | | | | | | | | support for the case where alignment<value size. These cases were silently miscompiled before this patch. Now they are overly verbose -especially storing is- and any front-end should still avoid misaligned memory accesses as much as possible. The bit juggling algorithm added here probably has some room for improvement still. llvm-svn: 118889
* Simplify uses of MVT and EVT. An MVT can be compared directlyDuncan Sands2010-11-031-1/+1
| | | | | | | with a SimpleValueType, while an EVT supports equality and inequality comparisons with SimpleValueType. llvm-svn: 118169
* Inline asm multiple alternative constraints development phase 2 - improved ↵John Thompson2010-10-291-0/+33
| | | | | | basic logic, added initial platform support. llvm-svn: 117667
* Improve lowering of sext to i128 on SPU.Kalle Raiskila2010-10-181-2/+7
| | | | | | | | The old algorithm inserted a 'rotqmbyi' instruction which was both redundant and wrong - it made shufb select bytes from the wrong end of the input quad. llvm-svn: 116701
* Implement two virtual functions in SPUTargetLowering.Kalle Raiskila2010-10-071-0/+26
| | | | | | | | | | Before the implementation of isLegalAddressingMode, some rare cases of code were miscompiled if optimized with the LoopStrengthReduce pass. It is unclear (to me) if LSR is "allowed" to produce wrong code with a bad TargetLowering, or if the bug is elsewhere and this patch just hides it. llvm-svn: 115919
* update a bunch of code to use the MachinePointerInfo version of getStore.Chris Lattner2010-09-211-3/+4
| | | | llvm-svn: 114461
* it's more elegant to put the "getConstantPool" andChris Lattner2010-09-211-3/+4
| | | | | | | | "getFixedStack" on the MachinePointerInfo class. While this isn't the problem I'm setting out to solve, it is the right way to eliminate PseudoSourceValue, so lets go with it. llvm-svn: 114406
* Silence compiler warning.Kalle Raiskila2010-09-091-1/+1
| | | | llvm-svn: 113478
* Fix CellSPU vector shuffles, again.Kalle Raiskila2010-09-081-7/+7
| | | | | | Some cases of lowering to rotate were miscompiled. llvm-svn: 113355
* Fix lowering of INSERT_VECTOR_ELT in SPU. Kalle Raiskila2010-08-291-3/+4
| | | | | | The IDX was treated as byte index, not element index. llvm-svn: 112422
* Fix SPU BE to use all the available return registers.Kalle Raiskila2010-08-241-34/+16
| | | | | | llc used to assert on the added testcase. llvm-svn: 111911
* Remove some dead code from SPU BE that remainedKalle Raiskila2010-08-241-18/+6
| | | | | | from 64bit vector support. llvm-svn: 111910
* Fix a bug with insertelement on SPU. Kalle Raiskila2010-08-181-6/+11
| | | | | | | The previous algorithm in LowerVECTOR_SHUFFLE didn't check all requirements for "monotonic" shuffles. llvm-svn: 111361
* Remove all traces of v2[i,f]32 on SPU. Kalle Raiskila2010-08-181-27/+0
| | | | | | | | The "half vectors" are now widened to full size by the legalizer. The only exception is in parameter passing, where half vectors are expanded. This causes changes to some dejagnu tests. llvm-svn: 111360
* Have SPU handle halfvec stores aligned by 8 bytes.Kalle Raiskila2010-08-091-9/+26

* Add preliminary v2f32 support for SPU. Like with v2i32, we justKalle Raiskila2010-08-021-0/+2
| | | | | | | | duplicate the instructions and operate on half vectors. Also reorder code in SPUInstrInfo.td for better coherency. llvm-svn: 110037
* Add preliminary v2i32 support for SPU backend. As there are noKalle Raiskila2010-08-021-3/+16
| | | | | | | | | | such registers in SPU, this support boils down to "emulating" them by duplicating instructions on the general purpose registers. This adds the most basic operations on v2i32: passing parameters, addition, subtraction, multiplication and a few others. llvm-svn: 110035
* Switch SPU calling convention (function arguments) Kalle Raiskila2010-07-081-12/+40

* Split the SDValue out of OutputArg so that SelectionDAG-independentDan Gohman2010-07-071-2/+4

| | | | | | | | | for an "i" constraint should get lowered; PR 6309. While this argument was passed around a lot, this is the only place it was used, so it goes away from a lot of other places. llvm-svn: 106893

* Use const qualifiers with TargetLowering. This eliminates severalDan Gohman2010-04-171-8/+9
| | | | | | | | | | | | | 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
