It's better not to rely on the diagnostics engine to pretty print the
argument to decltype. Instead, exercise the functionality in
DeclPrinterTest.
llvm-svn: 239197
We would crash in the DeclPrinter trying to pretty-print the
static_assert message. C++1z-style assertions don't have a message so
we would crash.
This fixes PR23756.

Adds tests verifying the proper dirs are found in the Debian 8/GCC4.9
layout for sparc (32bit), sparc (32bit) with lib64 multilib, and
sparc64.
The test cases added here also cover r239047, which fixed the linker
paths.

input / output with memory constraint.
One generally can't get address of a bit field, so the general solution is to
error on such cases. GCC does the same.

The main effect of this is to fix anomalies where certain -mfpu options didn't
disable everything that they should causing strange behaviour when combined
with -mcpu or -march values that themselves enabled fpu subtarget features,
e.g. -mfpu=fpv5-dp-d16 with -march=armv7em previously behaved the same as
-mfpu=fpv5-sp-d16 due to fp-only-sp not being disabled.
Invalid -mfpu options now also give an error, which is consistent with the
handling of the .fpu directive.

Before:
template <typename T>
auto aaaaaaaaaaaaaaaaaaaaaa(T t) -> decltype(eaaaaaaaaaaaaaaa<T>(t.a)
.aaaaaaaa());
After:
template <typename T>
auto aaaaaaaaaaaaaaaaaaaaaa(T t)
-> decltype(eaaaaaaaaaaaaaaa<T>(t.a).aaaaaaaa());
Also add a test case for a difficult template parsing case I stumbled accross.
Needs fixing.

This is a more correct representation than using "Equality" introduced
in r238942 which was a quick fix to solve an actual regression.
According to the typescript spec, arrows behave like "low-precedence"
assignments.
Before:
var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));
After:
var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));

Summary:
This patch enables lexing of `concept` and `requires` as keywords.
Further changes which add messages for future keyword compat are to
follow.
Test Plan:
Testing of C++14 + Concepts TS mode is added to
`test/Lexer/keywords_test.cpp`, which expects that the new keywords are
enabled under said mode.

GCC allows case-insensitive values for -mcpu, -march and -mtune options.
This patch implements the same behaviour for the -mcpu option.

They should be 'int' instead of 'long int' everywhere else except
NetBSD too, from what I gather in GCC's spec files. So, optimistically

The test passing was dependent upon your source tree being checked out
in a directory with a long enough path, to cause the diagnostics to
wrap at the expected locations.
Use stdin instead, so that the error messages consistently use
<stdin> as the filename, and get wrapped consistently.
llvm-svn: 239009
On ARM/AArch64, we currently always use EmitScalarExpr for the immediate
builtin arguments, instead of directly emitting the constant. When the
overflow sanitizer is enabled, this generates overflow intrinsics
instead of constants, breaking assumptions in various places.
Instead, use the knowledge of "immediates" to directly emit a constant:
- teach the tablegen backend to emit the "immediate" modifiers
- use those modifiers in the NEON CodeGen, on ARM and AArch64.
Fixes PR23517.

If we crash while handling headers, the crash report mechanism
currently tries to make a string out of a null pointer when it tries
to make up a file extension.
Map *-header input types to reasonable extensions to avoid this.

Files compiled with -via-file-asm should be byte for byte identical. This
change improves the checking on dash_s_no_change to detect non-code
differences. If there is a difference, the check goes on to compare code and
debug to try and be more informative.

The parameter types and return type do not need to be volatile just
because the pointer type's pointee type is volatile qualified. This is
an unnecessary pessimization.

The MSVC 2013 and 2015 implementation of std::atomic is specialized for
pointer types. The member functions are implemented using a static_cast
from void-ptr to function-ptr which is not allowed in the standard.
Permit this conversion if -fms-compatibility is present.
This fixes PR23733.
