This fixes PR14194.

I don't think this is possible with the current implementation but that may change eventually.

llvm-svn: 166877

llvm-svn: 166876

This turns loops like
  for (unsigned i = 0; i != n; ++i)
    p[i] = p[i+1];
into memmove, which has a highly optimized implementation in most libcs.

This was really easy with the new DependenceAnalysis :)

llvm-svn: 166875

Requires a lot less code and complexity on loop-idiom's side and the more
precise analysis can catch more cases, like the one I included as a test case.
This also fixes the edge-case miscompilation from PR9481.

Compile time performance seems to be slightly worse, but this is mostly due
to an extra LCSSA run scheduled by the PassManager and should be fixed there.

SCEV validator: Ignore CouldNotCompute/undef on both sides. This is mostly noise and blocks finding more severe bugs.

offer up my email to the spam lords for it. Hopefully this will
eventually be more automatic, but we don't want people to think there is
only one option.

The monolithic interface for instruction costs has been split into
several functions. This is the corresponding change. No functionality
change is intended.

llvm-svn: 166865

1. Fix a bug in getTypeConversion. When a *simple* type is split, we need to return the type of the split result.
2. Change the maximum vectorization width from 4 to 8.
3. A test for both.

to reduce.

so it could hold this information, and then used it to look up unfound names in the object pointer
if it exists.  This gets "frame var" to work for unqualified references to ivars captured in blocks.
But the expression parser is ignoring this information still.

llvm-svn: 166858

Removing the IsDynamic() and GetStaticValue() calls, so that they will default to the base class behavior:
 - non-dynamic
 - itself as the static value
This is in contrast with the previous behavior which could be confusing and could potentially cause issues when using those objects

llvm-svn: 166857

- Only read the statically-defined isa table in the
  shared cache once.  Only the dynamically-constructed
  isa table can change.

- Ignore the statically-defined isa table if its
  version isn't what we expect.

of vararg functions back to the stack.

llvm-svn: 166844

This method emits nodes for passing byval arguments in registers and stack.
This has the same functionality as existing functions PassByValArg64 and
WriteByValArg which will be deleted later.

llvm-svn: 166843

This method copies byval arguments passed in registers onto the stack and has
the same functionality as existing functions CopyMips64ByValRegs and
ReadByValArg which will be deleted later.
