In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.
This patch removes the Go debugger plugin.
The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.

This cleanup is designed to make the https://reviews.llvm.org/D32167 patch smaller and easier to read.
Cleanup in this patch:
Allow DWARFUnit subclasses to hand out the data that should be used when decoding data for a DIE. The information might be in .debug_info or could be in .debug_types. There is a new virtual function on DWARFUnit that each subclass must override:
virtual const lldb_private::DWARFDataExtractor &DWARFUnit::GetData() const;
This allows DWARFCompileUnit and eventually DWARFTypeUnit to hand out different data to be used when decoding the DIE information.
Add a new pure virtual function to get the size of the DWARF unit header:
virtual uint32_t DWARFUnit::GetHeaderByteSize() const = 0;
This allows DWARFCompileUnit and eventually DWARFTypeUnit to hand out different offsets where the first DIE starts when decoding DIE information from the unit.
Added a new function to DWARFDataExtractor to get the size of an offset:
size_t DWARFDataExtractor::GetDWARFSizeOfOffset() const;
Removed dead dumping and parsing code in the DWARFDebugInfo class.
Inlined a bunch of calls in DWARFUnit for accessors that were just returning integer member variables.
Renamed DWARFUnit::Size() to DWARFUnit::GetHeaderByteSize() as it clearly states what it is doing and makes more sense.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)
continue
if text:
filled = textwrap.wrap(text, width=(78-len(header)),
break_long_words=False)
for l in filled:
out.write(header+" "+l+'\n')
text = ""
out.write(line)
os.rename(tmp, sys.argv[1])

Code commonly checks if the parent DIE is DW_TAG_compile_unit.
But DW_TAG_partial_unit also acts as DW_TAG_compile_unit for DWZ
as DWZ is using DW_TAG_imported_unit only at the top unit level.

It was completly unused and broke the part of the encapsulation that
common code shouldn't depend on specific plugins or language specific
features.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

lldb::user_id_t out to the rest of LLDB:
1 - DWARF in .o files with debug map in executable: we would place the compile unit index in the upper 32 bits of the 64 bit value and the lower 32 bits would be the DIE offset
2 - DWO: we would place the compile unit offset in the upper 32 bits of the 64 bit value and the lower 32 bits would be the DIE offset
There was a mixing and matching of this and it wasn't done consistently.
Major changes include:
The DIERef constructor that takes a lldb::user_id_t now requires a SymbolFileDWARF:
DIERef(lldb::user_id_t uid, SymbolFileDWARF *dwarf)
It is needed so that it can be decoded correctly. If it is DWARF in .o files with debug map in executable, then we get the right compile unit from the SymbolFileDWARFDebugMap, otherwise, we use the compile unit offset and DIE offset for DWO or normal DWARF.
The function:
lldb::user_id_t DIERef::GetUID() const;
Now becomes
lldb::user_id_t DIERef::GetUID(SymbolFileDWARF *dwarf) const;
Again, we need the DWARF file to encode it correctly.
This removes the need for "lldb::user_id_t SymbolFileDWARF::MakeUserID() const" and for bool SymbolFileDWARF::UserIDMatches (lldb::user_id_t uid) const". There were also many places were doing things inneficiently like:
1 - encode a dw_offset_t into a lldb::user_id_t
2 - call the public SymbolFile interface to resolve types using the lldb::user_id_t
3 - This would then decode the lldb::user_id_t into a DIERef, and then try to find that type.
There are many places that are now doing this more efficiently by storing DW_AT_type form values as DWARFFormValue objects and then making a DIERef from them and directly calling the underlying function to resolve the lldb_private::Type, lldb_private::CompilerType, lldb_private::CompilerDecl, lldb_private::CompilerDeclContext.
If there are any regressions in DWARF with DWO, we will need to fix any issues that arise since the original patch wasn't functional for the much more widely used DWARF in .o files with debug map.

&Class::GetClangASTContext()" functions.
This cleans up type systems to be more pluggable. Prior to this we had issues:
- Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()"
- Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem
- Cleaned up Module so that it no longer has dedicated type system member variables:
lldb::ClangASTContextUP m_ast; ///< The Clang AST context for this module.
lldb::GoASTContextUP m_go_ast; ///< The Go AST context for this module.
Now we have a type system map:
typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap;
TypeSystemMap m_type_system_map; ///< A map of any type systems associated with this module
- Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract:
class CompilerType
{
...
//----------------------------------------------------------------------
// Return a new CompilerType that is a L value reference to this type if
// this type is valid and the type system supports L value references,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
GetLValueReferenceType () const;
//----------------------------------------------------------------------
// Return a new CompilerType that is a R value reference to this type if
// this type is valid and the type system supports R value references,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
GetRValueReferenceType () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a const modifier to this type if
// this type is valid and the type system supports const modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddConstModifier () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a volatile modifier to this type if
// this type is valid and the type system supports volatile modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddVolatileModifier () const;
//----------------------------------------------------------------------
// Return a new CompilerType adds a restrict modifier to this type if
// this type is valid and the type system supports restrict modifiers,
// else return an invalid type.
//----------------------------------------------------------------------
CompilerType
AddRestrictModifier () const;
//----------------------------------------------------------------------
// Create a typedef to this type using "name" as the name of the typedef
// this type is valid and the type system supports typedefs, else return
// an invalid type.
//----------------------------------------------------------------------
CompilerType
CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const;
};
Other changes include:
- Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);"
- Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed
