where the descriptor took a pointer to an object and
expected the Initialize function to dereference that
pointer and extract the isa value. This caused one
of our tests to fail.

KDP -- now with rudimentary process control (continue only) and read + write registers (which means we can see stack frames) for x86_64, i386 and ARM.

not correctly store the contents of Objective-C
classes. This was due to a combination of
factors:
1) Types were only being completed if we were
looking inside them for specific ivars
(using FindExternalVisibleDeclsByName).
We now look the complete type up at every
FindExternalLexicalDecls.
2) Even if the types were completed properly,
ValueObjectConstResult overrode the type
of every ValueObject using the complete type
for its class from the debug information.
Superclasses of complete classes are not
guaranteed to be complete. Although "frame
variable" uses the debug information,
the expression parser does now piece together
complete types at every level (as described
in Bullet 1), so I provided a way for the
expression parser to prevent overriding.
3) Type sizes were being miscomputed by
ClangASTContext. It ignored the ISA pointer
and only counted fields. We now correctly
count the ISA in the size of an object.

We can now read the relevant data structures for
the method list, and use a callback mechanism to
report their details to the AppleObjCTypeVendor,
which constructs appropriate Clang types.

data structures more rapidly. Also added fields
for the other data structures in a class.
I also fixed a problem where I accidentally used
hasExternalLexicalStorage() instead of
hasExternalVisibleStorage() to mark an
incomplete object.

populate Clang ObjCInterfaceDecls with their
ivars, methods, and properties. The default
implementation does nothing. I have also made
sure that AppleObjCRuntimeV2 creates
ObjCInterfaceDecls that actually get queried
appropriately.

the dynamic and static runtime class tables to
construct our isa table. This is putting the runtime
in contact with unrealized classes, which we need
to deal with in order to get accurate information.
That's the next piece of work.

This may (but shouldn't) break Linux (but I tested and it still worked on FreeBSD).
The same shell scripts are now used on Xcode and Makefiles, for generating
the SWIG bindings.
Some compatibility fixes were applied, too (python path, bash-isms, etc).

When attaching on ARM hosted debuggers we were incorrectly setting the triple to "arm-apple-ios". This was happening because in the post attach code, we would lookup the process info through the platform, and if successful, we would get the architecture of the process. This code uses sysctl() calls, but we can only get the CPU type, not the subtype, so we would get ARM for CPU type and nothing for the cpu subtype, so this would map to "arm-apple-ios". I fixed the code to get the cpu subtype from "hw.cpusubtype" which is what we really want for ARM, and not the architecture is already correct. "add-dsym" then works like a charm. I also improved the command output when the architecture changes to show the entire triple instead of just the arch name.

Partial fix for the above radar where we now resolve dsym mach-o files within the dSYM bundle when using "add-dsym" through the platform.

information from the Objective-C runtime.
This patch takes the old AppleObjCSymbolVendor and
replaces it with an AppleObjCTypeVendor, which is
much more lightweight. Specifically, the SymbolVendor
needs to pretend that there is a backing symbol file
for the Types it vends, whereas a TypeVendor only
vends bare ClangASTTypes. These ClangASTTypes only
need to exist in an ASTContext.
The ClangASTSource now falls back to the runtime's
TypeVendor (if one exists) if the debug information
doesn't find a complete type for a particular
Objective-C interface. The runtime's TypeVendor
maintains an ASTContext full of types it knows about,
and re-uses the ISA-based type query information used
by the ValueObjects.
Currently, the runtime's TypeVendor doesn't provide
useful answers because we haven't yet implemented a
way to iterate across all ISAs contained in the target
process's runtime. That's the next step.
