in-progress implementation of the Concepts TS. The recommended feature
test macro __cpp_experimental_concepts is set to 1 (as opposed to
201501) to indicate that the feature is enabled, but the
implementation is incomplete.
The link to the Concepts TS in cxx_status is updated to refer to the
PDTS (N4377). Additional changes related to __has_feature and
__has_extension are to follow in a later change.
Relevant tests include:
test/Lexer/cxx-features.cpp
The test file is updated with testing of the C++14 + Concepts TS mode.
The expected behaviour is the same as that of the C++14 modes except
for the case of __cpp_experimental_concepts."
- Hubert Tong.
Being committed for Hubert (as per his understanding with Richard Smith) as we start work on the concepts-ts following our preliminary strategy session earlier today.
The patch is tiny and seems quite standard.
Thanks Hubert!

When we find a member of the current instantation, the base of the
unresolved member expression is implicit; use nullptr for such
bases. This is not a change in behavior: the AST already contains null
in such cases, so non-asserts builds do the right thing already. Fixes

Assigns a token type (TT_JsFatArrow) to => tokens, and uses that to
more easily recognize and format fat arrow functions.
Improves function parsing to better recognize formal parameter
lists and return type declarations.
Recognizes arrow functions and parse function bodies as child blocks.

Using the target cpu to determine some behaviour is sprinkled in
several places in the driver, but in almost all the information that
is needed can be found in the triple. Restructure things so that the
triple is used, and the cpu is only used if the exact cpu name is
needed.
Also add a check that the -mcpu argument is valid, and correct the
-march argument checking so that it handles -march=native correctly. I
would have liked to move these checks into the computation of the
triple, but the triple is calculated several times in several places
and that would lead to multiple error messages for the same thing.

Don't print unused-argument warning for sanitizer-specific feature flag
if this sanitizer was eanbled, and later disabled in the command line.
For example, now:
clang -fsanitize=address -fsanitize-coverage=bb -fno-sanitize=address a.cc
doesn't print warning, but
clang -fsanitize-coverage=bb
does. Same holds for -fsanitize-address-field-padding= and
-fsanitize-memory-track-origins= flags.

MSVC 2015 includes the std::data() template function added to C++17. ADL
causes both cl.exe and clang-cl to prefer std::data over our static
helper here, and we get errors about converting int64_t* to StringRef.
Renaming it to bytes avoids the ambiguity.

Add a check for bool-like conversions for the condition expression of
conditional operators. This is similiar to the checking of condition
expressions of if statements, for-loops, while-loops, and do-while loops.
Specificially, this is to fix the problem of assert("message") not triggering
-Wstring-conversion when the assert macro uses a conditional operator.

-fprofile-instr-generate does not emit counter increment intrinsics
for Dtor_Deleting and Dtor_Complete destructors with assigned
counters. This causes unnecessary [-Wprofile-instr-out-of-date]
warnings during profile-use runs even if the source has never been
modified since profile collection.

There are 3 cases of defining static const member:
initialized inside the class, not defined outside the class.
initialized inside the class, defined outside the class.
not initialized inside the class, defined outside the class.
Revision r213304 was supposed to fix the linkage problem of case (1), but mistakenly it made case (2) behave the same.
As a result, out-of-line definition of static data member is not handled correctly.
Proposed patch distinguishes between cases (1) and (2) and allows to properly emit static const members under –fms-compatibility option.
This fixes http://llvm.org/PR21164.

Patch fixes codegen for aggregate copying of VLAs. Currently method CodeGenFunction::EmitAggregateCopy() does not support copying of VLAs. Patch checks if the size of the type is 0, then checks if the type is actually a variable-length array. Then it calculates total length for this array and calculates total size of the array in bytes:
<total number of elements in array> * aligned_sizeof(ElementType) (if copy assignment is requested).
If simple copying is requested, size is calculated like:
<total number of elements in array> * aligned_sizeof(ElementType) - aligned_sizeof(ElementType) + sizeof(ElementType).
memcpy() is used with this calculated size of the VLA.

The implicit conversion was causing issues for a helper being added that
would take an llvm::Function rather than an llvm::Value to make the
CallInst. Since we'll eventually need to specify the type of the call
explicitly anyway, fix these up to avoid the future ambiguity.

glibc's headers use __need_* macros to selectively export parts of themselves
to each other. This requires us to enter those files repeatedly when building
a glibc module.
This can be unreverted once we have a better mechanism to deal with that
non-modular aspect of glibc (possibly some way to mark a header as "textual if
this macro is defined").
