This just empties out the diag, which is fine.

Jordan and I discussed this, and we don't want this in the API.

that were already parsed in the same "indexing session".

An indexing session is defined as using the same CXIndexAction object
for multiple clang_indexSourceFile calls.
Passing CXIndexOpt_SkipParsedBodiesInSession as an indexing option will
enable the mode where we try to skip bodies that were already parsed in
another translation unit.

If a function's body was skipped, the "flags" field in the CXIdxDeclInfo
structure will have "CXIdxDeclFlag_Skipped" bit was set.

Jordan and I discussed this, and we are going to do this another way.

understand target implementation of any_extend / extload, just generate
zero_extend in place of any_extend for liveouts when the target knows the
zero_extend will be implicit (e.g. ARM ldrb / ldrh) or folded (e.g. x86 movz).

This is an alternative to the ImmutableMapRef interface where a factory
should still be canonicalizing by default, but in certain cases an
improvement can be made by delaying the canonicalization.

'currStmt', 'CleanedState', and 'EntryNode' were being set, but only ever
used locally.

Previously we made three passes over the set of dead symbols, and removed
them from the state /twice/. Now we combine the autorelease pass and the
symbol death pass, and only have to remove the bindings for the symbols
that leaked.

llvm-svn: 169527

Previously we would search for the last statement, then back up to the
entrance of the block that contained that statement. Now, while we're
scanning for the statement, we just keep track of which blocks are being
exited (in reverse order).

ProgramStateRef::Retain isn't free!

This doesn't seem to make much of a difference in practice, but it does
have the potential to avoid a trip through the constraint manager.

llvm-svn: 169524

Whenever we touch a single bindings cluster multiple times, we can delay
canonicalizing it until the final access. This has some interesting
implications, in particular that we shouldn't remove an /empty/ cluster
from the top-level map until canonicalization.

This is good for a 2% speedup or so on the test case in
<rdar://problem/12810842>

This feature was probably intended to improve diagnostics, but was currently
only used when dumping the Environment. It shows what location a given value
was loaded from, e.g. when evaluating an LValueToRValue cast.

Summary: + tests arranged in groups, as their number is already quite large.
