The pointer was being implicitly converted to a StringRef and the size was being passed into the bool. Since the bool has a default value normally, no one noticed that the wrong number of arguments was given.

The ELF symbol visibilities are:
- internal: Not visibile across DSOs, cannot pass address across DSOs
- hidden: Not visibile across DSOs, can be called indirectly
- default: Usually visible across DSOs, possibly interposable
- protected: Visible across DSOs, not interposable
LLVM only supports the latter 3 visibilities. Internal visibility is in
theory useful, as it allows you to assume that the caller is maintaining
a PIC register for you in %ebx, or in some other pre-arranged location.
As far as LLVM is concerned, this isn't worth the trouble. Using hidden
visibility is always correct, so we can just do that.
Resolves PR9183.

compile actions via CXXFLAGS, and to be ignored for rules that specify custom

This recommits r250398 with fixes to the tests for bot failures.
Add "-target x86_64-unknown-linux" to the clang invocations that
check for the gold plugin.
llvm-svn: 250455
Rolling this back for now since there are a couple of bot failures on
the new tests I added, and I won't have a chance to look at them in detail
until later this afternoon. I think the new tests need some restrictions on
having the gold plugin available.
This reverts commit r250398.
llvm-svn: 250402
Summary:
Add clang support for -flto=thin option, which is used to set the
EmitFunctionSummary code gen option on compiles.
Add -flto=full as an alias to the existing -flto.
Add tests to check for proper overriding of -flto variants on the
command line, and convert grep tests to FileCheck.

There was a minor problem with a test. Sorry for the noise yesterday.
This patch adds missing pieces to clang, including the PS4 toolchain
definition, added warnings, PS4 defaults, and Driver changes needed for
our compiler.

Add support for the `-fdebug-prefix-map=` option as in GCC. The syntax is
`-fdebug-prefix-map=OLD=NEW`. When compiling files from a path beginning with
OLD, change the debug info to indicate the path as start with NEW. This is
particularly helpful if you are preprocessing in one path and compiling in
another (e.g. for a build cluster with distcc).
Note that the linearity of the implementation is not as terrible as it may seem.
This is normally done once per file with an expectation that the map will be
small (1-2) entries, making this roughly linear in the number of input paths.
Addresses PR24619.

With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.
Also fix a bug in the Windows compatibility argument parsing
in which the "rightmost argument wins" principle failed.

ASTUnit was creating multiple FileManagers and throwing them away. Reuse
the one from Tooling. No functionality change now but necessary for
VFSifying tooling.

In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes. It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure). There is a
desire to support __declspec in Playstation code, and possibly other
environments. This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword. Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

The patch makes it possible to parse CUDA files that contain host/device
functions with identical signatures, but different attributes without
having to physically split source into host-only and device-only parts.
This change is needed in order to parse CUDA header files that have
a lot of name clashes with standard include files.

This feature is controlled with CC1 option -fcuda-target-overloads

This reapply a variant commit r247179 after post-commit review from
D.Blaikie.
Hopefully I got it right this time: lifetime of initializer list ends
as with any expression, which make invalid the pattern:
ArrayRef<int> Arr = { 1, 2, 3, 4};
Just like StringRef, ArrayRef shouldn't be used to initialize local
variable but only as function argument.
