Basically typo correction will try to offer a correction instead of looking into type dependent base classes.
I found this problem while parsing Microsoft ATL code with clang.

-15% on ARMDisassembler.cpp (Release build). It's not that great to add another
layer of caching to the caching-heavy LVI but I don't see a better way.

libgcc sets the stack limit field in TCB to 256 bytes above the actual
allocated stack limit. This means if the function's stack frame needs
less than 256 bytes, we can just compare the stack pointer with the
stack limit. This should result in lesser calls to __morestack.
llvm-svn: 145766
Currently LLVM pads the call to __morestack with a add and sub of 8
bytes to esp. This isn't correct since __morestack expects the call
to be followed directly by a ret.
This commit also adjusts the relevant test-case.

class. The thing with Objective C classes is the debug info might have a
definition that isn't just a forward decl, but it is incomplete. So we need to
look and see if we can find the complete definition and avoid recursing a lot
due to the fact that our accelerator tables will have many versions of the
type, but only one complete one. We might not also have the complete type
and we need to deal with this correctly.

Objective-C, making symbol lookups for various raw
Objective-C symbols work correctly. The IR interpreter
makes these lookups because Clang has emitted raw
symbol references for ivars and classes.
Also improved performance in SymbolFiles, caching the
result of asking for SymbolFile abilities.

when deserialized, fixing random crashes in libclang.
Also simplifies how OpaqueValueExprs are [de]serialized.
The reader/writer automatically retains pointer equality of sub-statements (when a
statement node is referenced in multiple nodes), so no need to manually handle it.

for all our external AST sources that lets us associate
arbitrary flags with the types we put into the AST
contexts. Also added an API on ClangASTContext that
allows access to these flags given only an ASTContext
and a type.
Because we don't have access to RTTI, and because at
some point in the future we might encounter external
AST sources that we didn't make (so they don't subclass
ClangExternalASTSourceCommon) I added a magic number
that we check before doing anything else, so that we
can catch that problem as soon as it appears.

the same value) to this variable. This code could be refactored, but it doesn't
matter since the old JIT is going away. Add tsan annotations to ignore the
race.

object file can correctly make these symbols which will abstract us from the
file format and ABI and we can then ask for the objective C class symbol for
a class and find out which object file it was defined in.

the function it is being asked to step through, so that even if we get the trampoline
target wrong (for instance) we will still not lose control.
The other fix here is to tighten up the handling of the case where the current plan
doesn't explain the stop, but a plan above us does. In that case, if the plan that
does explain the stop says it is done, we need to clean up the plans below it and
continue on with our processing.

"main" files that import modules. When loading any of these kinds of
AST files, we make the modules that were imported visible into the
translation unit that loaded the PCH file or preamble.

Fixed an issue where if we have the DWARF equivalent of:
struct foo;
class foo { ... };
Or vice versa, we wouldn't be able to find the complete type. Since many
compilers allow forward declarations to have struct and definitions to have
class, we need to be able to deal with both cases. This commit fixes this in
the DWARF parser.

change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.
One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.
