Jim Grosbach 20eac92d88 Clean up LSDA name generation and use for SJLJ exception handling. This
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

Bob Wilson e0636a7aed Remove unneeded ARM-specific DAG nodes for VLD* and VST* Neon operations.
The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.

Dale Johannesen 6bbeda41b9 Make linkerprivate work for ARM and PPC. Testcase covers
all Darwin targets; could be split into separate tests for
the chip subdirectories, but from Chris' last mail on testing
I assume he'd rather have only one test.  Generic seems to be
the best available, maybe there should be a Darwin subdirectory?

Anton Korobeynikov a6b3ce203a Allow targets to specify their choice of calling conventions per
libcall. Take advantage of this in the ARM backend to rectify broken

it could be of use in MakePIC16Libcall, which works unchanged.

Bob Wilson 6f34e278c7 Now that all the legal Neon shuffles (or at least the ones that have been

Bob Wilson eb54d51759 Create a new ARM-specific DAG node, VDUP, to represent a splat from a

Bob Wilson cce31f6831 During legalization, change Neon vdup_lane operations from shuffles to
