doing assembly-only, and unify the Driver's PIC argument parsing.
On a few architectures, parsing of assembly files annoyingly depends
on whether PIC is enabled or not. This was handled for external 'as'
already (passing -KPIC), but was missed for calls to the standalone
internal assembler.
The integrated-as.s test needed to be modified to not expect
-fsanitize=address to be unused, as now fsanitize *IS* used for
assembly, since -fsanitize=memory can sometimes imply -fPIE, which the
assembler needs to know (gack!!).

"generic" cpu was wrongly handled as exact real CPU name of ARMv8.1A architecture.
This has been fixed, now it is abstract name, suitable for any arch.

This has been disabled for a long time, but:
1) Initializers work (and apparently they're re reason why this was disabled).
2) various tests happen to hit this code path and the invariant seems to be
always verified.

__builtin_object_size would return incorrect answers for many uses where
type=3. This fixes the inaccuracy by making us emit 0 instead of LLVM's
objectsize intrinsic.
Additionally, there are many cases where we would emit suboptimal (but
correct) answers, such as when arrays are involved. This patch fixes
some of these cases (please see new tests in test/CodeGen/object-size.c
for specifics on which cases are improved)

Summary:
If a module was unavailable (either a missing requirement on the module
being imported, or a missing file anywhere in the top-level module (and
not dominated by an unsatisfied `requires`)), we would silently treat
inclusions as textual. This would cause all manner of crazy and
confusing errors (and would also silently "work" sometimes, making the
problem difficult to track down).
I'm really not a fan of the `M->isAvailable(getLangOpts(), getTargetInfo(),
Requirement, MissingHeader)` function; it seems to do too many things at
once, but for now I've done things in a sort of awkward way.
The changes to test/Modules/Inputs/declare-use/module.map
were necessitated because the thing that was meant to be tested there
(introduced in r197805) was predicated on silently falling back to textual
inclusion, which we no longer do.
The changes to test/Modules/Inputs/macro-reexport/module.modulemap
are just an overlooked missing header that seems to have been missing since
this code was committed (r213922), which is now caught.

This enables Clang to correctly handle code such as:

where it would otherwise error due to trying to generate the default

blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables.
We have to rebuild several expression to be sure that all variables are unique.

Currently, arguments are passed via the string attribute 'command',
assuming a shell-escaped / quoted command line to extract the original
arguments. This works well enough on Unix systems, but turns out to be
problematic for Windows tools to generate.
This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.
Currently there is no plan to retire 'commands': there are enough
different use cases where users want to create their own mechanism for
creating compilation databases, that it doesn't make sense to force them
all to implement shell command line parsing.

file in the .pcm files. This allows a smaller set of files to be sent to a
remote build worker when building with explicit modules (for instance, module
map files need not be sent along with the corresponding precompiled modules).
This doesn't actually make the embedded files visible to header search, so
it's not useful as a packaging format for public header files.

We risk iterator invalidation issues if we use a DenseMap to hold the

Also, don't assume that MaterializedGlobalTemporaryMap won't regrow
between when we initially perform a lookup and later on when we actually
try to insert into it.
