Lang Hames dd98c497b9 Add an option to the MI scheduler to cut off scheduling after a fixed number of
instructions have been scheduled. Handy for tracking down scheduler bugs, or

Howard Hinnant e59dbd7b82 I would really like to write the handlers in terms of C++11 atomics. This would give us the best performance, portablity, and safety tradeoff. Unfortunately I can not yet do that. So I've put the desired code in comments, and reverted the handler getters to the slower but safer legacy atomic intrinsics.

Howard Hinnant 4ac72dd982 I've moved __cxa_terminate_handler, __cxa_unexpected_handler and __cxa_new_handler from the public header cxxabi.h into the private header cxa_handlers.hpp. During this move I've also moved them from namespace __cxxabiapple into the global namespace. They are, and have always been extern C and so the namespace (or lack of it) does not affect their ABI. In general external clients should not reference these symbols. They are atomic variables and will be changing into C++11 atomic variables in the future. However for those few clients who really need access to them, their name, mangling, size, alignment and layout will remain stable. You just may need your own declaration of them. Include guards have been added to the private header cxa_exception.hpp. The private header cxa_default_handlers.hpp has been removed and the default handlers are now file-static. Include guards have been added to the private header cxa_handlers.hpp.

Preston Gurd 48ccc4df0b This patch adds X86 instruction itineraries for non-pseudo opcodes in
X86InstrCompiler.td.
 
It also adds –mcpu-generic to the legalize-shift-64.ll test so the test
will pass if run on an Intel Atom CPU, which would otherwise
produce an instruction schedule which differs from that which the test expects.

Chandler Carruth 93f2c7b584 Make the formatting of this file more consistent, and fix the 80-columns

Suggestions on still better / more consistent formatting would be
welcome. I'm actually tempted to use a macro to define all of the
delegate methods...

Jordy Rose bf38f20e79 [analyzer] Mark a failed-realloc's result as an interesting symbol between the realloc call and the null check, so we get nicer path notes. Fixes a regression introduced by the diagnostic pruning added in r152361.
This is accomplished by calling markInteresting /during/ path diagnostic generation, and as such relies on deterministic ordering of BugReporterVisitors -- namely, that BugReporterVisitors are run in /reverse/ order from how they are added. (Right now that's a consequence of storing visitors in an ImmutableList, where new items are added to the front.) It's a little hacky, but it works for now.

I think this is the best we can do without storing the relation between the old and new symbols, and that would be a hit whether or not there ends up being an error.

David Blaikie a90e86aa36 Use character literals for vexing initialization fixit hints.
Instead of suggesting " = 0" for "char c();", suggest " = '\0'", and similarly
for other char types (wide, 16, and 32). Add tests for all these, and since
this means testing such hints under C++0x, add tests for some untested C++0x
hint cases in the existing code, including suggesting nullptr for pointer
initialization.

This sets up the initialization helper to provide better type fidelity that
will be especially helpful for non-assignment cases (such as fixit-correcting
NULL usage in function calls (eg: foo(char) + foo(NULL) => foo('\0') instead
of the less informative foo(0)))

Jordy Rose 61c974b492 [analyzer] Use a FoldingSet to cache simple RetainSummary instances, rather than explicitly keeping DoNothing and StopTracking summaries and nothing else.
I tried to test the effects of this change on memory usage and run time, but what I saw on retain-release.m was indistinguishable from noise (debug and release builds). Even so, some caveman profiling showed 101 cache hits that we would have generated new summaries for before (i.e. not default or stop summaries), and the more code we analyze, the more memory we should save.

Maybe we should have a standard project for benchmarking the retain count checker's memory and time?

Jordy Rose 9046bcd03b Kill cocoa::deriveNamingConvention and cocoa::followsFundamentalRule. They are now just simple wrappers around method families, and method decls can cache method family lookups. Also, no one is using them right now.
The one difference between ObjCMethodDecl::getMethodFamily and Selector::getMethodFamily is that the former will do some additional sanity checking, and since CoreFoundation types don't look like Objective-C objects, an otherwise interesting method will get a method family of OMF_None. Future clients that use method families should consider how they want to handle CF types.

Jordy Rose 7063883e8c [analyzer] Remove duplicate work on deriving method behavior. No functionality change.
The cocoa::deriveNamingConventions helper is just using method families anyway now, and the way RetainSummaryTemplate works means we're allocating an extra summary for every method with a relevant family.

Also, fix RetainSummaryTemplate to do the right thing w/r/t annotating an /existing/ summary. This was probably the real cause of <rdar://problem/10824732> and the fix in r152448.
