They are left over from our previous attempt at DWARF64. The new attempt
is not using them, and they also don't have equivalents in the llvm
DWARFDataExtractor class.
|
|
LLDB's implementation of DWARFDataExtractor has a method that returns a
llvm::DWARFDataExtractor. In some cases, like DebugNamesDWARFIndex::Create, we
were passing an LLVM::DWARFDataExtractor to a function that expects a
LLVM:DataExtractor by value. This is causing slicing of the derived class.
While slicing is not inherently bad, it can be dangerous if the constructor of
the derived class mutates the base class in a way that leaves it in an invalid
state after slicing.

This is a follow-up to https://reviews.llvm.org/D140896, split into
several parts as it touches a lot of files.

Similar to D67797 (DataExtractor).

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

This patch adds two convenience methods named GetAsLLVM to the LLDB
counterparts of the DWARF DataExtractor and the DWARF context. The
DWARFContext, once created, is cached for future usage.

LLVM doesn't produce DWARF64, and neither does GCC. LLDB's support
for DWARF64 is only partial, and if enabled appears to also not work.
Finally, it's untested. Removing this makes merging LLVM and
LLDB's DWARF parsing implementations simpler.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

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.

*** 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.
