perform them.
- A ToolChain is a coherent set of tools use in a compilation
process. The idea is that a ToolChain holds roughly the information
(specs, search paths, etc.) that is in a single gcc binary.
- The default ToolChain is selected by the host and will generally
correspond to what the default system compiler would do. However,
this can be over-riden for a variety of purposes, for example the
by the driver driver or for testing.

that is neither a definition nor a forward declaration and where X has
not yet been declared as a tag, introduce a declaration
into the appropriate scope (which is likely *not* to be the current
scope). The rules for the placement of the declaration differ slightly
in C and C++, so we implement both and test the various corner
cases. This implementation isn't 100% correct due to some lingering
issues with the function prototype scope (for a function parameter
list) not being the same scope as the scope of the function
definition. Testcase is FIXME'd; this probably isn't an important issue.
Addresses <rdar://problem/6484805>.

- Little script for scanning a compile log and summarizing warnings,
errors, assertions, and crashes.
- Is very slow, and stack trace regexs probably only work on Darwin.

- Refactor caching logic into a helper class PTHSpellingSearch
- Allow "random accesses" in the spelling cache, thus catching the remaining
cases where 'getSpelling' wasn't hitting the PTH cache
For -Eonly, PTH, Cocoa.h:
- This reduces wall time by 3% (user time unchanged, sys time reduced)
- This reduces the amount of paged source by 1112K.
The remaining 1112K still being paged in is from somewhere else
(investigating).

of ScopedDecls (using the new ScopedDecl::NextDeclInScope
pointer). Performance-wise:
- It's a net win in memory utilization, since DeclContext is now one
pointer smaller than it used to be (std::vectors are typically 3
pointers; we now use 2 pointers) and
- Parsing Cocoa.h with -fsyntax-only (with a Release-Asserts Clang)
is about 1.9% faster than before, most likely because we no longer
have the memory allocations and copying associated with the
std::vector.
I'll re-enable serialization of DeclContexts once I've sorted out the
NextDeclarator/NextDeclInScope question.

filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.
llvm-svn: 61994
Add isa/cast/dyncast support for ObjCContainerDecl.
Renamed classprop_iterator/begin/end to prop_iterator/begin/end (the class prefix was confusing).
More simplifications to Sema::ActOnAtEnd()...
Added/changed some FIXME's as a result of the above work.
