Summary:
The portion in MipsAsmParser is responsible for figuring out which expansion to
use, while the portion in MipsTargetStreamer is responsible for emitting it.

This allows us to remove the call to isIntegratedAssemblerRequired() which is
currently ensuring the effect of .cprestore only occurs when writing objects.

The small functional change is that the memory offsets are now correctly
printed as signed values.

Summary:
* Moved all the emit*() helpers to MipsTargetStreamer.
* Moved createNop() to MipsTargetStreamer as emitNop() and emitEmptyDelaySlot().
  This instruction has been split to distinguish between the 'nop' instruction
  and the nop used in delay slots which is sometimes a different nop to the
  'nop' instruction (e.g. for short delay slots on microMIPS).
* Moved createAddu() to MipsTargetStreamer as emitAddu().
* Moved createAppropriateDSLL() to MipsTargetStreamer as emitDSLL().

This reverts commit r268033 as it breaks some buildbots.

llvm-svn: 268035

With Polly checked into LLVM it was since a long time possible to compile
clang/opt/bugpoint with Polly support directly linked in, instead of only
providing Polly as a separate loadable module. This commit switches the
default from providing Polly as a module to linking Polly into tools, such
that it becomes unnecessary to load the Polly module when playing with Polly.
Such configuration has shown a lot more convenient for day-to-day Polly use.

This change does not impact the default behavior of any tool, if Polly is not
explicitly enabled when calling clang/opt/bugpoint Polly does not affect
compilation.

This change also does not impact normal LLVM/clang checkouts that do not
contain Polly.

FIXME: We currently don't support folding constant pshufb shuffle masks containing undef elements.
llvm-svn: 268016

Summary:
The goal is for each operand type to have its own parse function and
at the same time share common code for tracking state as different
instruction types share operand types (e.g. glc/glc_flat, etc).

Introduce parseAMDGPUOperand which can parse any optional operand.
DPP and Clamp/OMod have custom handling for now. Sam also suggested
to have class hierarchy for operand types instead of table. This
can be done in separate change.

Remove parseVOP3OptionalOps, parseDS*OptionalOps, parseFlatOptionalOps,
parseMubufOptionalOps, parseDPPOptionalOps.
Reduce number of definitions of AsmOperand's and MatchClasses' by using common base class.
Rename AsmMatcher/InstPrinter methods accordingly.
Print immediate type when printing parsed immediate operand.
Use 'off' if offset/index register is unused instead of skipping it to make it more readable (also agreed with SP3).
Update tests.

This was being treated the same as private, which has an immediate
offset. For unknown, it probably means it's for a computation not
actually being used for accessing memory, so it should not have a
nontrivial addressing mode.

In case of missing live intervals for a physical registers
getLanesWithProperty() would report 0 which was not a safe default in
all situations. Add a parameter to pass in a safe default.
No testcase because in-tree targets do not skip computing register unit
live intervals.

Also cleanup the getXXX() functions to not perform the
RequireLiveIntervals checks anymore so we do not even need to return
safe defaults.

llvm-svn: 267977

With the DetectDeadLanes pass in place we cannot run into situations
anymore where defs suddenly become dead.
Also add a missing check so we do not try to add an undef flag to a
physreg (found by visual inspection, no failing test).

We need to keep loop hints from the original loop on the new vector loop.
Failure to do this meant that, for example:

  void foo(int *b) {
  #pragma clang loop unroll(disable)
    for (int i = 0; i < 16; ++i)
      b[i] = 1;
  }

this loop would be unrolled. Why? Because we'd vectorize it, thus dropping the
hints that unrolling should be disabled, and then we'd unroll it.

This requirement was a huge hack to keep LiveVariables alive because it
was optionally used by TwoAddressInstructionPass and PHIElimination.
However we have AnalysisUsage::addUsedIfAvailable() which we can use in
those passes.

This re-applies r260806 with LiveVariables manually added to PowerPC to
hopefully not break the stage 2 bots this time.

I closely followed the precedents set by the vectorizer:

* With -Rpass-missed, the loop is reported with further details pointing
to -Rpass--analysis.

* -Rpass-analysis reports the details why distribution has failed.

* Regardless of -Rpass*, when distribution fails for a loop where
distribution was forced with the pragma, a warning is produced according
to -Wpass-failed.  In this case the analysis info is also printed even
without -Rpass-analysis.

llvm-svn: 267952

The next patch will start using these for -Rpass-analysis so they won't
be internal-only anymore.

Move the 'Skipping; ' prefix that some of the message are using into the
'fail' function.  We don't want to include this prefix in
the -Rpass-analysis report.
