965a166eb7 autoconf: put generated clang files in build dir
It was writing generated files to the clang srcdir when
'--with-clang-srcdir' was specified.

061efcfb3e TargetPassConfig: confine the MC configuration to TargetMachine.
Passes prior to instructon selection are now split into separate configurable stages.
Header dependencies are simplified.
The bulk of this diff is simply removal of the silly DisableVerify flags.

Sorry for the target header churn. Attempting to stabilize them.

069df954a1 Object: avoid undefined behavior when bounds-checking
Don't form an out of bounds pointer just to test if it
would be out of bounds.

Also perform the same bounds checking for all the previous

77180e0b40 Handle register mask operands in setPhysRegsDeadExcept().
Calls that use register mask operands don't have implicit defs for
returned values.  The register mask operand handles the call clobber,
but it always behaves like a set of dead defs.

Add live implicit defs for any implicitly defined physregs that are
actually used.

ffbd0715fa Increment DFAStateEntryTable index for sentinel entry.
When adding the {-1, -1} entry to the DFAStateInputTable, we
need to increment the index used to populate the DFAStateEntryTable.
Otherwise, the entry table will be off by one for each transition
after the {-1, -1} entry. PR11908.

59cb77fb11 Handle all live physreg defs in the same place.
SelectionDAG has 4 different ways of passing physreg defs to users.
Collect all of the uses at the same time, and pass all of them to
MI->setPhysRegsDeadExcept() to mark the remaining defs dead.

The setPhysRegsDeadExcept() function will soon add the required
implicit-defs to instructions with register mask operands.

7e413e9c94 The type-legalizer often scalarizes code. One of the common patterns is extract-and-truncate.
In this patch we optimize this pattern and convert the sequence into extract op of a narrow type.
This allows the BUILD_VECTOR dag optimizations to construct efficient shuffle operations in many cases.

843ee2e6a4 Added TargetPassConfig. The first little step toward configuring codegen passes.
Allows command line overrides to be centralized in LLVMTargetMachine.cpp.
LLVMTargetMachine can intercept common passes and give precedence to command line overrides.
Allows adding "internal" target configuration options without touching TargetOptions.
Encapsulates the PassManager.
Provides a good point to initialize all CodeGen passes so that Pass ID's can be used in APIs.
Allows modifying the target configuration hooks without rebuilding the world.

42865588d7 Add pseudo-registers for pairs, triples, and quads of D registers.
NEON loads and stores accept single and double spaced pairs, triples,
and quads of D registers.  This patch adds new register classes to
accurately model those constraints:

  Dn, Dn+1    Dn, Dn+2
  ----------------------
  DPair       DPairSpc
  DTriple     DTripleSpc
  DQuad       DQuadSpc

Also extend the existing QQ and QQQQ register classes to contains all Q
pairs and quads instead of just the aligned ones.

These new register classes will make it possible to accurately model
constraints on NEON loads and stores, and we can get rid of all the NEON
pseudo-instructions.  The late scheduler will be able to accurately
model instruction dependencies from the explicit operands.

This more than doubles the number of ARM registers, but the backend
passes are quite good at handling this. The llc -O0 compile time only
regresses by 1.5%.  Future work on register mask operands will recover
this regression.
