Pirama Arumuga Nainar 8e2e9d6f4c Add -fnative-half-arguments-and-returns
Summary:
r246764 handled __fp16 arguments and returns for AAPCS, but skipped this
handling for OpenCL.  Simlar to OpenCL, RenderScript also handles __fp16
type natively.

This patch adds the -fnative-half-arguments-and-returns command line
flag to allow such languages to skip this coercion of __fp16.

Nicolai Haehnle 95e8ffd398 AMDGPU: Overload return type of llvm.amdgcn.buffer.load.format
Summary:
Allow the selection of BUFFER_LOAD_FORMAT_x and _XY. Do this now before
the frontend patches land in Mesa. Eventually, we may want to automatically
reduce the size of loads at the LLVM IR level, which requires such overloads,
and in some cases Mesa can generate them directly.

Nicolai Haehnle ad63638f6d AMDGPU/SI: Add llvm.amdgcn.buffer.atomic.* intrinsics
Summary:
These intrinsics expose the BUFFER_ATOMIC_* instructions and will be used
by Mesa to implement atomics with buffer semantics. The intrinsic interface
matches that of buffer.load.format and buffer.store.format, except that the
GLC bit is not exposed (it is automatically deduced based on whether the
return value is used).

The change of hasSideEffects is required for TableGen to accept the pattern
that matches the intrinsic.

Nicolai Haehnle 3003ba00a3 AMDGPU: use ComplexPattern for offsets in llvm.amdgcn.buffer.load/store.format
Summary:
We cannot easily deduce that an offset is in an SGPR, but the Mesa frontend
cannot easily make use of an explicit soffset parameter either. Furthermore,
it is likely that in the future, LLVM will be in a better position than the
frontend to choose an SGPR offset if possible.

Since there aren't any frontend uses of these intrinsics in upstream
repositories yet, I would like to take this opportunity to change the
intrinsic signatures to a single offset parameter, which is then selected
to immediate offsets or voffsets using a ComplexPattern.

Pete Cooper 64d075ec07 Always cache resolved paths as it even saves on StringMap lookups.
Now that the resolved path cache stores the StringRef's, its
best to just always cache the results, even when realpath isn't
used.  This way we'll still avoid the StringMap hashing and lookup.

This also conveniently reorganises this code in a way I need for
a future patch.

Pete Cooper ef4e36ad99 Use StringRef's in resolved path cache to avoid extra internString lookups. NFC.
ResolvedPaths was storing std::string's as a cache. We would then take those strings and look them up in the internString pool to get a unique StringRef for each path.

This patch changes ResolvedPaths to store the StringRef pointing in to the internString pool itself. This way, when getResolvedPath returns a string, we know we have the StringRef we would find in the pool anyway. We can avoid the duplicate memory of the std::string's, and also the time from the lookup.

Unfortunately my profiles show no runtime change here, but it should still save memory allocations which is nice.

Tim Shen 5cdf75084a [PPC, FastISel] Fix ordered/unordered fcmp
For fcmp, major concern about the following 6 cases is NaN result. The
comparison result consists of 4 bits, indicating lt, eq, gt and un (unordered),
only one of which will be set. The result is generated by fcmpu
instruction. However, bc instruction only inspects one of the first 3
bits, so when un is set, bc instruction may jump to to an undesired
place.

More specifically, if we expect an unordered comparison and un is set, we
expect to always go to true branch; in such case UEQ, UGT and ULT still
give false, which are undesired; but UNE, UGE, ULE happen to give true,
since they are tested by inspecting !eq, !lt, !gt, respectively.

Similarly, for ordered comparison, when un is set, we always expect the
result to be false. In such case OGT, OLT and OEQ is good, since they are
actually testing GT, LT, and EQ respectively, which are false. OGE, OLE
and ONE are tested through !lt, !gt and !eq, and these are true.

Lang Hames 6935c2d322 [Support] Add ExitOnError utility to support tools that use the exit-on-error
idiom.

Most LLVM tool code exits immediately when an error is encountered and prints an
error message to stderr. The ExitOnError class supports this by providing two
call operators - one for Errors, and one for Expected<T>s. Calls to code that
can return Errors (or Expected<T>s) can use these calls to bail out on error,
and otherwise continue as if the operation had succeeded. E.g.

Error foo();
Expected<int> bar();

int main(int argc, char *argv[]) {
  ExitOnError ExitOnErr;

  ExitOnErr.setBanner(std::string("Error in ") + argv[0] + ":");

  // Exit if foo returns an error. No need to manually check error return.
  ExitOnErr(foo());

  // Exit if bar returns an error, otherwise unwrap the contained int and
  // continue.
  int X = ExitOnErr(bar());

  // ...

  return 0;

Bruno Cardoso Lopes 016b2d0ddc Reapply [VFS] Add 'overlay-relative' field to YAML files
This reapplies r261552.

The VFS overlay mapping between virtual paths and real paths is done through
the 'external-contents' entries in YAML files, which contains hardcoded paths
to the real files.

When a module compilation crashes, headers are dumped into <name>.cache/vfs
directory and are mapped via the <name>.cache/vfs/vfs.yaml. The script
generated for reproduction uses -ivfsoverlay pointing to file to gather the
mapping between virtual paths and files inside <name>.cache/vfs. Currently, we
are only capable of reproducing such crashes in the same machine as they
happen, because of the hardcoded paths in 'external-contents'.

To be able to reproduce a crash in another machine, this patch introduces a new
option in the VFS yaml file called 'overlay-relative'. When it's equal to
'true' it means that the provided path to the YAML file through the
-ivfsoverlay option should also be used to prefix the final path for every
'external-contents'.

Example, given the invocation snippet "... -ivfsoverlay
<name>.cache/vfs/vfs.yaml" and the following entry in the yaml file:

"overlay-relative": "true",
"roots": [
...
  "type": "directory",
  "name": "/usr/include",
  "contents": [
    {
      "type": "file",
      "name": "stdio.h",
      "external-contents": "/usr/include/stdio.h"
    },
...

Here, a file manager request for virtual "/usr/include/stdio.h", that will map
into real path "/<absolute_path_to>/<name>.cache/vfs/usr/include/stdio.h.

This is a useful feature for debugging module crashes in machines other than
the one where the error happened.
