method returns the DefaultLayout::_segments field. The type of this field is
a vector of Segment<ELFT>* pointers. This type cannot be implicitly casted to
the range<ChunkIter>.

Previously, the synthesized AST contained an rvalue DeclRefExpr for 'self'.
Now, it has an lvalue DeclRefExpr wrapped in an lvalue-to-rvalue
ImplicitCastExpr, which is what's generated when an ivar access is written
in the source.
No (intended) functionality change.

Newer unix systems have 32 bit uid and gid types, but the archive format was
not updated. Fortunately, these fields are not normally used. Just truncate
the data to fit in 6 chars.

With the old linkage types removed, set the linkage to external for both
dllimport and dllexport to reflect what's currently supported.
llvm-svn: 199220
Representing dllexport/dllimport as distinct linkage types prevents using
these attributes on templates and inline functions.
Instead of introducing further mixed linkage types to include linkonce and
weak ODR, the old import/export linkage types are replaced with a new
separate visibility-like specifier:
define available_externally dllimport void @f() {}
@Var = dllexport global i32 1, align 4
Linkage for dllexported globals and functions is now equal to their linkage
without dllexport. Imported globals and functions must be either
declarations with external linkage, or definitions with
AvailableExternallyLinkage.

Sorry, I don't understand why the warning is generated (a gcc
bug?). Anyhow, the change should improve readablity. No functionality
change intended.

This fixes a regression intruced by r198113.
Revision r198113 introduced an algorithm that tries to fold a vector shift
by immediate count into a build_vector if the input vector is a known vector
of constants.
However the algorithm only worked under the assumption that the input vector
type and the shift type are exactly the same.
This patch disables the folding of vector shift by immediate count if the
input vector type and the shift value type are not the same.

Full language modes usually get listed before minor language extensions in
LangOpts, so that subsequent sub-modes can predicate on the major modes.
This also lends to a cleanup in CompilerInvocation to better indicate to the
reader that MSVCCompat is a superset of MicrosoftExt.
Cleanup only.

There's been long-standing confusion over the role of these two options. This
commit makes the necessary changes to differentiate them clearly, following up
from r198936.
MicrosoftExt (aka. fms-extensions):
Enable largely unobjectionable Microsoft language extensions to ease
portability. This mode, also supported by gcc, is used for building software
like FreeBSD and Linux kernel extensions that share code with Windows drivers.
MSVCCompat (aka. -fms-compatibility, formerly MicrosoftMode):
Turn on a special mode supporting 'heinous' extensions for drop-in
compatibility with the Microsoft Visual C++ product. Standards-compilant C and
C++ code isn't guaranteed to work in this mode. Implies MicrosoftExt.
Note that full -fms-compatibility mode is currently enabled by default on the
Windows target, which may need tuning to serve as a reasonable default.
See cfe-commits for the full discourse, thread 'r198497 - Move MS predefined
type_info out of InitializePredefinedMacros'
No change in behaviour.

fastcall requires @ as global prefix instead of _ but getNameWithPrefix
wrongly assumes the OutName buffer is empty and replaces at index 0.
For imported functions this buffer is pre-filled with "__imp_" resulting
in broken "@_imp_foo@0" mangling.
Instead replace at the proper index. We also never have to prepend the
@-prefix because this fastcall mangling is only used on 32-bit Windows
targets which have _ has global prefix.
llvm-svn: 199203
We cannot simply change the start column to accomodate for the @ in an
ObjC string literal as that will make clang-format happily violate the
column limit.
Use a different workaround instead. However, a better long-term
solution might be to join the @ and the rest of the literal into a
single token.

Builders that have -fms-compatibility on by default define size_t implicitly.
Tests that provide conflicting definitions would cause unintended failures.
