Devang Patel f3292b2196 Revert r124611 - "Keep track of incoming argument's location while emitting 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+)

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.

Kalle Raiskila 0a9dd405a5 Fix memory access lowering on SPU, adding 
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.

Kalle Raiskila 5f2034c455 Improve lowering of sext to i128 on SPU. 
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.

Kalle Raiskila a845022ddd Implement two virtual functions in SPUTargetLowering. 
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.

Chris Lattner 676c61db0e update a bunch of code to use the MachinePointerInfo version of getStore. 
llvm-svn: 114461
 2010-09-21 18:41:36 +00:00
Chris Lattner 82fd06d3ce it's more elegant to put the "getConstantPool" and 
"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.

Kalle Raiskila e60b5161d1 Fix a bug with insertelement on SPU. 
The previous algorithm in LowerVECTOR_SHUFFLE 
didn't check all requirements for "monotonic" shuffles.

Kalle Raiskila ab49360f59 Remove all traces of v2[i,f]32 on SPU. 
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.

 2010-08-02 11:22:10 +00:00
Kalle Raiskila 68b3886678 Add preliminary v2f32 support for SPU. Like with v2i32, we just 
duplicate the instructions and operate on half vectors. 

Also reorder code in SPUInstrInfo.td for better coherency.

 2010-08-02 10:25:47 +00:00
Kalle Raiskila 622f8eb981 Add preliminary v2i32 support for SPU backend. As there are no 
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.

Dale Johannesen ce97d55ad9 The hasMemory argument is irrelevant to how the argument 
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.

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.
