This is tied with the LLVM side of the change to expose the debug
information compression types to clang. We now track the compression
type as an enumeration rather than a boolean. We still use the same
value (GNU) that we did previously. This is in preparation to support
passing down the compression type and switch it based on the command
line.
llvm-svn: 305039
This is a preparatory change to expose the debug compression style to
clang. It requires exposing the enumeration and passing the actual
value through to the backend from the frontend in actual value form
rather than a boolean that selects the GNU style of debug info
compression.
Minor tweak to the ELF Object Writer to use a variable for re-used
values. Add an assertion that debug information format is one of the
two currently known types if debug information is being compressed.

This adds support for Symbols, StringTable, and FrameData subsection
types. Even though these subsections rarely if ever appear in a PDB
file (they are usually in object files), there's no theoretical reason
why they *couldn't* appear in a PDB. The real issue though is that in
order to add support for dumping and writing them (which will be useful
for object files), we need a way to test them. And since there is no
support for reading and writing them to / from object files yet, making
PDB support them is the best way to both add support for the underlying
format and add support for tests at the same time. Later, when we go
to add support for reading / writing them from object files, we'll need
only minimal changes in the underlying read/write code.
llvm-svn: 305037
This is the same change for the YAML Output style applied to the
raw output style. Previously we would queue up all subsections
until every one had been read, and then output them in a pre-
determined order. This was because some subsections need to be
read first in order to properly dump later subsections. This
patch allows them to be dumped in the order they appear.

The pdb2yaml and raw subcommands did something very
similar but with a different output format, and they
used a lot of the same command line options, but each
one re-implemented the command line option with slightly
different spellings / options. This patch merges them
together into a single definition which is shared by
both subcommands. This new syntax also allows for more
flexibility in the way debug subsections are dumped.

Since D17854 LinkerSubsectionsViaSymbols is unnecessary.
It is interfering with ThinLTO implementation of CFI-ICall, where
the aliases used on the !LinkerSubsectionsViaSymbols branch are
needed to export jump tables to ThinLTO backends.

These used to be virtual methods that would enable doing the right thing with only a TerminatorInst pointer. I believe they were also acting as vtable anchors in my cases. I think the fact that they had a separate name ending in V was to allow a version without V to be called without a virtual call in a pre-C++11 final keyword world.
Where possible the base methods in TerminatorInst dispatch directly to the public methods in the classes that have the same signature. For some classes this wasn't possible so I've left private method versions that match the name and signature of the version in TerminatorInst. All versions have been moved into the class definitions since we no longer need vtable anchors here.

Summary:
This allows the clang-query tool to use matchers like

This diff fixes printf "fixits" in the case when there is
a wrapping macro and the format string needs multiple replacements.
In the presence of a macro there is an extra logic in EditedSource.cpp
to handle multiple uses of the same macro argument
(see the old comment inside EditedSource::canInsertInOffset)
which was mistriggerred when the argument was used only once
but required multiple adjustments), as a result the "fixit"
was breaking down the format string
by dropping the second format specifier, i.e.
Log1("test 4: %s %s", getNSInteger(), getNSInteger())
was getting replaced with
Log1("test 4: %ld ", (long)getNSInteger(), (long)getNSInteger())
(if one removed the macro and used printf directly it would work fine).
In this diff we track the location where the macro argument is used and
(as it was before) the modifications originating from all the locations
except the first one are rejected, but multiple changes are allowed.
Test plan: make check-all

No IR tests were added with rL304313 ( https://reviews.llvm.org/D28637 ),
so I want these for extra coverage if we enable memcmp expansion for x86.
As shown, nothing is expanded for x86 in CGP yet.
Also fundamentally, we're doing an IR transform, so we should have IR tests
for just that part. If something goes wrong, we need to know if the bug is
in CGP or later lowering.

The only use in-tree I can find for BuiltinTypes.ResultTy is a single
store to it. We otherwise just recompute what it should be later on (and
sometimes do things like argument conversions in the process of
recomputing it).
Since it's impossible to test if the value stored there is sane, and we
don't use it anyway, we should probably just drop the field.
I'll do a follow-up patch to rename BuiltinTypes.ParamTypes ->
BuiltinParamTypes in a bit. Wanted to keep this patch relatively
minimal.
Thanks to Petr Kudryavtsev for bringing this up!
