     Test data formatter commands. ... Assertion failed: (isa<X>(Val) && "cast<Ty>() argument of incompatible type!"), function cast, file llvm/include/llvm/Support/Casting.h, line 239.

b57e4a1bc6 Roll back the changes I made in r193907 which created a new Frame
pure virtual base class and made StackFrame a subclass of that.  As
I started to build on top of that arrangement today, I found that it
wasn't working out like I intended.  Instead I'll try sticking with
the single StackFrame class -- there's too much code duplication to
make a more complicated class hierarchy sensible I think.

f23bf7432c Add a new base class, Frame. It is a pure virtual function which
defines a protocol that all subclasses will implement.  StackFrame
is currently the only subclass and the methods that Frame vends are
nearly identical to StackFrame's old methods.

Update all callers to use Frame*/Frame& instead of pointers to
StackFrames.

This is almost entirely a mechanical change that touches a lot of
the code base so I'm committing it alone.  No new functionality is
added with this patch, no new subclasses of Frame exist yet.

I'll probably need to tweak some of the separation, possibly moving
some of StackFrame's methods up in to Frame, but this is a good
starting point.

779f921311 Fix the format warnings.
In almost all cases, the misuse is about "%lu" being used instead of the correct "%zu" (even though these are compatible on 64-bit platforms in practice). There are even a couple of cases where "%ld" (ie., signed int) is used instead of "%zu", and one where "%lu" is used instead of "%" PRIu64.

Fixes bug #17551.

This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair

This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars
In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain)

With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible
This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection

9191db47da <rdar://problem/14496092>
Fixed an issue with reexported symbols on MacOSX by adding support for symbols re-exporting symbols. There is now a new symbol type eSymbolTypeReExported which contains a new name for the re-exported symbol and the new shared library. These symbols are only used when a symbol is re-exported as a symbol under a different name.

Modified the expression parser to be able to deal with finding the re-exported symbols and track down the actual symbol it refers to.

b0e33d4165 Fix endianness in ObjectFile::CopyData
ObjectFile::CopyData is used to copy a block of target memory to the
caller's buffer (e.g. for "memory read").  This should be a straight
memcpy, and not byte-swapped if the target and host have different
endianness.

Add a new DataExtractor::CopyData() method that performs this straight
copy and use it in ObjectFile::CopyData().

not have breakpoints set on it inserted into code that does have a valid line number.  So allow
that line number, and the ThreadPlanStepRange should just continue stepping over 0 line ranges
as if they had the same line number as whatever we were previously stepping through.

2cd21b87cd Update RegisterContextLLDB::GetFullUnwindPlanForFrame() to use the architectural-
default-at-first-instruction UnwindPlan if we're at the beginning of a function and
the ABI can provide us with an UnwindPlan to get out of there before falling back
to the generic architectural default UnwindPlan (which usually assumes that the stack
has already been set up.)

Update the FuncUnwinders methods to gracefully handle the case where an assembly
profiler may not be available.

Fix a bug where FuncUnwinders::GetUnwindPlanArchitectureDefaultAtFunctionEntry was
returning the wrong UnwindPlan to its caller.

6e264d39dc Adds a DW_OP_call_frame_cfa handler when evaluating DWARF 3/4 expressions
in LLDB that load the canonical frame address rather than a location list.

- Handles the simple case where a CFA can be pulled from the current stack frame.
- Fixes more than one hundred failing tests with gcc 4.8!

TODO: Use UnwindPlan::GetRowForFunctionOffset if the DWARFExpression needs
to be evaluated in a context analogous to a virtual unwind (perhaps using RegisterContextLLDB).

- Also adds some comments to DWARFCallFrameInfo whenever I got confused.

2540a8a7bc Fixed GetModuleSpecifications() to work better overall:
- MachO files now correctly extract the UUID all the time
- More file size and offset verification done for universal mach-o files to watch for truncated files
- ObjectContainerBSDArchive now supports enumerating all objects in BSD archives (.a files)
- lldb_private::Module() can not be properly constructed using a ModuleSpec for a .o file in a .a file
- The BSD archive plug-in shares its cache for GetModuleSpecifications() and the create callback
- Improved printing for ModuleSpec objects

57ee306789 Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

3046e66830 Cleanup on the unified section list changes. Main changes are:
- ObjectFile::GetSymtab() and ObjectFile::ClearSymtab() no longer takes any flags
- Module coordinates with the object files and contain a unified section list so that object file and symbol file can share sections when they need to, yet contain their own sections.

Other cleanups:
- Fixed Symbol::GetByteSize() to not have the symbol table compute the byte sizes on the fly
- Modified the ObjectFileMachO class to compute symbol sizes all at once efficiently
- Modified the Symtab class to store a file address lookup table for more efficient lookups
- Removed Section::Finalize() and SectionList::Finalize() as they did nothing
- Improved performance of the detection of symbol files that have debug maps by excluding stripped files and core files, debug files, object files and stubs
- Added the ability to tell if an ObjectFile has been stripped with ObjectFile::IsStripped() (used this for the above performance improvement)

f02500c74c Added the ability to get a list of types from a SBModule or SBCompileUnit. Sebastien Metrot wanted this, and sent a hollowed out patch. I filled in the blanks and did the low level implementation. The new functions are:
//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// module.
///
/// @param[in] type_mask
///     A bitfield that consists of one or more bits logically OR'ed
///     together from the lldb::TypeClass enumeration. This allows
///     you to request only structure types, or only class, struct
///     and union types. Passing in lldb::eTypeClassAny will return
///     all types found in the debug information for this module.
///
/// @return
///     A list of types in this module that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBModule::GetTypes (uint32_t type_mask)


//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// compile unit.
///
/// @param[in] type_mask
///    A bitfield that consists of one or more bits logically OR'ed
///    together from the lldb::TypeClass enumeration. This allows
///    you to request only structure types, or only class, struct
///    and union types. Passing in lldb::eTypeClassAny will return
///    all types found in the debug information for this compile
///    unit.
///
/// @return
///    A list of types in this compile unit that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBCompileUnit::GetTypes (uint32_t type_mask = lldb::eTypeClassAny);

This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want.

d8cf1a119d Huge performance improvements when one breakpoint contains many locations.
325,000 breakpoints for running "breakpoint set --func-regex ." on lldb itself (after hitting a breakpoint at main so that LLDB.framework is loaded) used to take up to an hour to set, now we are down under a minute. With warm file caches, we are at 40 seconds, and that is with setting 325,000 breakpoint through the GDB remote API. Linux and the native debuggers might be faster. I haven't timed what how much is debug info parsing and how much is the protocol traffic to/from GDB remote.

That there were many performance issues. Most of them were due to storing breakpoints in the wrong data structures, or using the wrong iterators to traverse the lists, traversing the lists in inefficient ways, and not optimizing certain function name lookups/symbol merges correctly.

Debugging after that is also now very efficient. There were issues with replacing the breakpoint opcodes in memory that was read, and those routines were also fixed.
