It is based on the observation that during parsing the comment that should be

parsed.

version of this code) were committed to LLDB in r160186.

Don't treat overflow in floating-point conversions as a hard error in constant evaluation. <rdar://problem/11874571>.

Fixes pr13353.cpp.

Remove assertions and turn what used the be the assertion into a logged error with instructions on what to attach to a radar so we can track down why this is happening.

Call "drain" on the auto release pool as it will do the right thing for both GC and non-GC apps. It will also quiet the static analyzer.

A standalone pattern defined in a multiclass expansion should handle
null_frag references just like patterns on instructions. Follow-up to
r160333.

These functions have obviously never been used before.
They should be identical to the idf_ext_iterator counterparts.

Checks against nil often appear as guards in macros, and comparing
Objective-C literals to nil has well-defined behavior (if tautological).

On OS X, 'nil' has not been typed as 'id' since 10.6 (possibly earlier),
so the warning was already not firing, but other runtimes continue to use
((id)0) or some variant. This change accepts comparisons to any null pointer;
to keep it simple, it looks through all casts (not just casts to 'id').

Suggested by Ted, since string literal comparison is at least slightly more
sensible than comparison of runtime literals. (Ambiguous language on
developer.apple.com implies that strings are guaranteed to be uniqued within
a translation unit and possibly across a linked binary.)

Recovering as if the user had actually called -isEqual: is a bit too far from
the semantics of the program as written, /even though/ it's probably what they
intended.

llvm-svn: 160377

This code has been moved around multiple times, but seems to have been
obsolete ever since we started handled references like pointers.

It began choking since Chandler's r159547, possibly due to improper expression on grep from TclParser to ShParser.

Make it possible to prune individual graph edges from a post-order
traversal by specializing the po_iterator_storage template. Previously,
it was only possible to prune full graph nodes. Edge pruning makes it
possible to remove loop back-edges, for example.

Also replace the existing DFSetTraits customization hook with a
po_iterator_storage method for observing the post-order. DFSetTraits was
only used by LoopIterator.h which now provides a po_iterator_storage
specialization.

Thanks to Sean and Chandler for reviewing.

To fetch a subprogram name we should not only inspect the DIE for this subprogram, but optionally inspect
its specification, or its abstract origin (even if there is no inlining), or even specification of an abstract origin.
