Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.
Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.
Bulk renames for things that used to return a ClangASTType which is now CompilerType:
"Type::GetClangFullType()" to "Type::GetFullCompilerType()"
"Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
"Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
"Value::GetClangType()" to "Value::GetCompilerType()"
"Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
"ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
many more renames that are similar.

Another step towards isolating all language/AST specific code into the files to further abstract specific implementations of parsing types for a given language.

Target and breakpoints options were added:
breakpoint set --language lang --name func
settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers). If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

A few extras were fixed
- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected.
- Since some places want to access the address as a reference, I added a few new functions to symbol:
Address &Symbol::GetAddressRef();
const Address &Symbol::GetAddressRef() const;
Linux test suite passes just fine now.

Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.
None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.
llvm-svn: 238581
I am fixing this by:
1 - make sure we aren't trying to set the symbol file for a module to the same thing it already has and leaving it alone if it is the same
2 - keep all old symbol files around in the module in case there are any outstanding type references

So that we don't have to update every single #include in the entire
codebase to #include this new header (which used to get included by

This removes Host::Backtrace from the codebase, and changes all
call sites to use llvm::sys::PrintStackTrace(). This makes the
functionality available for all platforms, and even for platforms
which currently had a supported implementation of Host::Backtrace,
this patch should enable richer information in stack traces, such
as file and line number information, as well as giving it the
ability to unwind through inlined functions.

This is part of a larger effort to reduce header file footprints.
Combined, these patches reduce the build time of LLDB locally by
over 30%. However, they touch many files and make many changes,
so will be submitted in small incremental pieces.

but not necessarily identical to the inferior binaries.

Background: dyld binaries often have extra symbols in their symbol table like "malloc" and "free" for the early bringup of dyld and we often don't want to set breakpoints in dynamic linker binaries. We also don't want to call the "malloc" or "free" function in dyld when a user writes an expression like "(void *)malloc(123)" so we need to avoid doing name lookups in dyld. We mark Modules as being dynamic link editors and this helps do correct lookups for breakpoints by name and function lookups.

When you create a target, it tries to look for the platform's list
of supported architectures for a match. The match it finds can
contain specific triples, like i386-pc-windows-msvc. Later, we
overwrite this value with the most generic triple that can apply
to any platform with COFF support, causing some of the fields of
the triple to get overwritten.
This patch changes the behavior to only merge in values from the COFF
triple if the fields of the matching triple were unknown/unspecified
to begin with.
This fixes load address resolution on Windows, since it enables the
DynamicLoaderWindows to be used instead of DynamicLoaderStatic.

To do this, I fixed the CPPLanguageRuntime::StripNamespacesFromVariableName() function to use a regular expression that correctly determines if the name passed to it is a qualfied C++ name like "a::b::c" or "b::c". The old version of this function was treating '__54-[NSUserScriptTask executeWithInterpreter:arguments::]_block_invoke' as a match with a basename of ']_block_invoke'.
Also fixed a case in the by name lookup of functions where we wouldn't look for the full name if we actually tried to call CPPLanguageRuntime::StripNamespacesFromVariableName() and got an empty basename back.

with binaries in the dyld shared cache (esp on iOS) where the file
address for the executable binary (maybe from memory, maybe from
an expanded copy of the dyld shared cache) is different from the
file address in the dSYM. In that case, ObjectFileMachO replaces
the file addresses from the original binary with the dSYM file
addresses (usually 0-based) -- lldb doesn't have a notion of two
file addresses for a given module so they need to agree.
There was a cache of file addresses over in the Symtab so I added
a method to the Module and the objects within to clear any file address
caches if they exist, and added an implementation in the Symtab
module to do that.

This change fixes build breaks on Linux and MacOSX lldb.

off_t is a type which is used for file offsets. Even more
specifically, it is only used by a limited number of C APIs that
deal with files. Any usage of off_t where the variable is not
intended to be used with one of these APIs is a bug, by definition.
This patch corrects some easy mis-uses of off_t, generally by
converting them to lldb::offset_t, but sometimes by using other
types such as size_t, when appropriate.
The use of off_t to represent these offsets has worked fine in
practice on linux-y platforms, since we used _FILE_OFFSET_64 to
guarantee that off_t was a uint64. On Windows, however,
_FILE_OFFSET_64 is unrecognized, and off_t will always be 32-bit.
So the usage of off_t on Windows actually leads to legitimate bugs.
