David Blaikie 0328feb086 DebugInfo: Filter DWARFv5 TUs out of the debug_info unit list when CUs requested
Since DWARFv5 places TUs in debug_info, some of DWARFContext's APIs have
become a bit erroneous, including TUs in the CU list by accident.
Correct that by providing compile_units (& dwo_compile_units) that
filter out the type units from the debug_info units.

David Stenberg 91bd9db2cd [DebugInfo] Allow GNU macro extension to be read
Allow the GNU .debug_macro extension to be parsed and printed by
llvm-dwarfdump. In an upcoming patch support will be added for emitting
that format also.

Sourabh Singh Tomar 93aee9ca86 [DWARF5]: Added support for dumping strx forms in llvm-dwarfdump
This patch adds support for dumping DW_MACRO_define_strx,
DW_MACRO_undef_strx in llvm-dwarfdump. These forms are currently
supported only in debug_macro section.

Sourabh Singh Tomar 85b49ecb78 [DWARF5]: Added support for DW_MACRO_import form in llvm-dwarfdump
GCC emits this new form along with others forms(supported in llvm-dwardump)
and since it's support was missing in llvm-dwarfdump, it was not
able to correctly dump the content a debug_macro section for GCC
generated binaries.

This patch extends llvm-dwarfdump to support this form,
now GCC generated debug_macro section can be correctly dumped
using llvm-dwarfdump.

Sourabh Singh Tomar 69c8fb1c65 [DWARF5] Added support for debug_macro section parsing and dumping in llvm-dwarfdump.
Summary:
This patch adds parsing and dumping DWARFv5 .debug_macro section in llvm-dwarfdump,
it does not introduce any new switch. Existing switch "--debug-macro"
should be used to dump macinfo or macro section.

David Blaikie 4ce3e5074b DebugInfo: Separate different debug_macinfo contributions & print the offset of a contribution 2020-03-02 19:30:30 -08:00
David Blaikie 39c308f6b8 DebugInfo: Use separate macinfo contributions for each CU
The macinfo support was broken for LTO situations, by terminating
macinfo lists only once - multiple macinfo contributions were correctly
labeled, but they all continued/flowed into later contributions until
only one terminator appeared at the end of the section.

Correctly terminate each contribution & fix the parsing to handle this
situation too. The parsing fix is also necessary for dumping linked
binaries - the previous code would stop at the end of the first
contribution - missing all later contributions in a linked binary.

It'd be nice to improve the dumping to print the offsets of each
contribution so it'd be easier to know which CU AT_macro_info refers to
which macinfo contribution.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Jonas Devlieghere 6921753994 [Support] Move syntax highlighting into support
Move the DWARF syntax highlighting into support. This has several
advantages, most notably that this makes the WithColor RAII wrapper
available outside libDebugInfo. Furthermore, several projects all have
their own code for handling colored output. This provides a place to
centralize it.

This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.

Chandler Carruth 6bda14b313 Sort the remaining #include lines in include/... and lib/....
I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.

I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.

This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.

Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings.  Convert these to native line endings.

There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.
