Eric Liu 467c5f9ce0 [clangd] Store preamble macros in dynamic index.
Summary:
Pros:
o Loading macros from preamble for every completion is slow (see profile).
o Calculating macro USR is also slow (see profile).
o Sema can provide a lot of macro completion results (e.g. when filter is empty,
60k for some large TUs!).

Cons:
o Slight memory increase in dynamic index (~1%).
o Some extra work during preamble build (should be fine as preamble build and
indexAST is way slower).

Jonas Devlieghere f1f3e7377c [DWARF Verifier] Add helper function to dump DIEs. [NFC]
It's pretty common for the verifier to dump the relevant DIE when it

because we have to pass the DIDumpOptions to the DIE's dump method. This
patch adds a helper function to the verifier to make this easier.

Matthias Braun 726e12cf0c ScheduleDAG: Cleanup dumping code; NFC
- Instead of having both `SUnit::dump(ScheduleDAG*)` and
  `ScheduleDAG::dumpNode(ScheduleDAG*)`, just keep the latter around.
- Add `ScheduleDAG::dump()` and avoid code duplication in several
  places. Implement it for different ScheduleDAG variants.
- Add `ScheduleDAG::dumpNodeName()` in favor of the `SUnit::print()`
  functions. They were only ever used for debug dumping and putting the
  function into ScheduleDAG is consistent with the `dumpNode()` change.

Dean Michael Berris b64f71b029 [XRay][compiler-rt] FDRLogWriter Abstraction
Summary:
This change introduces an `FDRLogWriter` type which is responsible for
serialising metadata and function records to character buffers. This is
the first step in a refactoring of the implementation of the FDR runtime
to allow for more granular testing of the individual components of the
implementation.

The main contribution of this change is a means of hiding the details of
how specific records are written to a buffer, and for managing the
extents of these buffers. We make use of C++ features (templates and
some metaprogramming) to reduce repetition in the act of writing out
specific kinds of records to the buffer.

In this process, we make a number of changes across both LLVM and
compiler-rt to allow us to use the `Trace` abstraction defined in the
LLVM project in the testing of the runtime implementation. This gives us
a closer end-to-end test which version-locks the runtime implementation
with the loading implementation in LLVM.

We also allow using gmock in compiler-rt unit tests, by adding the
requisite definitions in the `AddCompilerRT.cmake` module.

Finally, we've gone ahead and updated the FDR logging implementation to
use the FDRLogWriter for the lowest-level record-writing details.

Following patches will isolate the state machine transitions which
manage the set-up and tear-down of the buffers we're using in multiple
threads.

This adds a preprocessor callback for the `__has_include` and

Successful checking for the presence of a header should add it to the list of

Reid Kleckner 78381c63ae [MS] Defer dllexport inline friend functions like other inline methods
This special case was added in r264841, but the code breaks our
invariants by calling EmitTopLevelDecl without first creating a
HandlingTopLevelDeclRAII scope.

This fixes the PCH crash in https://crbug.com/884427. I was never able
to make a satisfactory reduction, unfortunately. I'm not very worried
about this regressing since this change makes the code simpler while
passing the existing test that shows we do emit dllexported friend
function definitions. Now we just defer their emission until the tag is
fully complete, which is generally good.

Zachary Turner c41ce8355f [PDB] Better support for enumerating pointer types.
There were several issues with the previous implementation.

1) There were no tests.
2) We didn't support creating PDBSymbolTypePointer records for
   builtin types since those aren't described by LF_POINTER
   records.
3) We didn't support a wide enough variety of builtin types even
   ignoring pointers.

This patch fixes all of these issues.  In order to add tests,
it's helpful to be able to ignore the symbol index id hierarchy
because it makes the golden output from the DIA version not match
our output, so I've extended the dumper to disable dumping of id
fields.
