lambda expressions (other than their capture initializers) nor blocks. Do walk
into default argument expressions and default initializer expressions.
These bugs were causing us to produce broken CFGs whenever a lambda expression
was used to initialize a libstdc++ std::function object!

Parser::ParseDeclarationSpecifiers eagerly updates the source range of
the DeclSpec with the current token position. However, it might not
consume any more tokens.
Fix this by only setting the start of the range, not the end. This way
the SourceRange will be invalid if we don't consume any more tokens.
This fixes PR20413.

llvm revision 210639 renamed the -global-merge backend option to
-enable-global-merge. This change simply updates clang to match that.

Previously we were building up the inalloca struct in the usual pattern
of return type followed by arguments. However, on Windows, 'this'
always precedes the 'sret' parameter, so we need to insert it into the
struct first as a special case.
llvm-svn: 213990
The target method of the thunk will perform the cleanup. This can't be
tested in 32-bit x86 yet because passing something by value would create
an inalloca, and we refuse to generate broken code for that.

CL's /Zp flag is analogous to GCC's -fpack-struct, it controls the
default maximum alignment of records.

Specifically the part where we removed a warning to be compatible with GCC, which has been widely regarded as a bad idea.
I'm not quite happy with how obtuse this warning is, especially in the fairly common case of a 32-bit integer literal, so I've got another patch awaiting review that adds a fixit to reduce confusion.

* Track override set across module load and save
* Track originating module to allow proper re-export of #undef
* Make override set properly transitive when it picks up a #undef
This fixes nearly all of the remaining macro issues with self-host.

Summary:
This patch extends the __asm parser to make it keep parsing input tokens
as inline assembly if a single-line __asm line is followed by another line
starting with __asm too. It also makes sure that we correctly keep
matching braces in such situations by separating the notions of how many
braces we are matching and whether we are in single-line asm block mode.

implicit parts of the initialization and never re-create them).

Current versions of ld64 can't cope with "aarch64" being stored. I'm fixing
that, but in the transitionary period we'll need to still emit "arm64".

While -fno-rtti-data would correctly avoid referencing the RTTI complete
object locator in the VFTable itself, it would emit them anyway.

The class seems to have an invariant that Entries is non-empty if
Invalid is false. It appears this method was previously private, and
all internal uses checked Invalid. Now there is an external caller, so
check Invalid to avoid array OOB underflow.
Fixes PR20420.

This flag specifies that we are building an implementation file of the
module <name>, preventing importing <name> as a module. This does not
consider this to be the 'current module' for the purposes of doing
modular checks like decluse or non-modular-include warnings, unlike
-fmodule-name.
This is needed as a stopgap until:
1) we can resolve relative includes to a VFS-mapped module (or can
safely import a header textually and as part of a module)
and ideally
2) we can safely do incremental rebuilding when implementation files
import submodules.

arm64_be doesn't really exist; it was useful for testing while AArch64 and
ARM64 were separate, but now the only real way to refer to the system is
aarch64_be.
llvm-svn: 213747
The main subtlety here is that the Darwin tools still need to be given "-arch
arm64" rather than "-arch aarch64". Fortunately this already goes via a custom
function to handle weird edge-cases in other architectures, and it tested.
I removed a few arm64_be tests because that really isn't an interesting thing
to worry about. No-one using big-endian is also referring to the target as
arm64 (at least as far as toolchains go). Mostly they date from when arm64 was
a separate target and we *did* need a parallel name simply to test it at all.
Now aarch64_be is sufficient.
