The Intel MCU psABI requires floating-point values to be passed in-reg.
This makes the x86-32 ABI code respect "-mfloat-abi soft" and generate float inreg arguments.

Summary:
Similar to rL248426 (which was a followup to rL248379 and rL248424), add the
required libraries for OpenMP on the linker command line, and update the test
case.

If a RegExp contains a character group with a quote (/["]/), the
trailing end of it is first tokenized as a string literal, which leads
to the merging code seeing an unbalanced bracket.
This change parses regex literals from the left hand side. That
simplifies the parsing code and also allows correctly handling escapes
and character classes, hopefully correctly parsing all regex literals.
Patch by Martin Probst, thank you.
Review: http://reviews.llvm.org/D13765
llvm-svn: 250648
During the initial template parse for this code, 'member' is unresolved
and we don't know anything about it:
struct A { int member };
template <typename T>
struct B : public T {
using T::member;
static void f() {
(void)member; // Could be static or non-static.
}
};
template class B<A>;
The pattern declaration contains an UnresolvedLookupExpr rather than an
UnresolvedMemberExpr because `f` is static, and `member` should never be
a field. However, if the code is invalid, it may become a field, in
which case we should diagnose it.

via -fmodule-file= to be turned off; in that case, just include the relevant
files textually. This allows module files to be unconditionally passed to all
compile actions via CXXFLAGS, and to be ignored for rules that specify custom
incompatible flags.

If you increase the number of diags of a particular type by one more than the
number available you get the nice assert message. If you do it by two more
than available you get the old non-helpful message. Combining the two makes
sense I think.

r246877 made __builtin_object_size substantially more aggressive with
unknown bases if Type=1 or Type=3, which causes issues when we encounter
code like this:
struct Foo {
int a;
char str[1];
};
const char str[] = "Hello, World!";
struct Foo *f = (struct Foo *)malloc(sizeof(*f) + strlen(str));
strcpy(&f->str, str);
__builtin_object_size(&f->str, 1) would hand back 1, which is
technically correct given the type of Foo, but the type of Foo lies to
us about how many bytes are available in this case.
This patch adds support for this "writing off the end" idiom -- we now
answer conservatively when we're given the address of the very last
member in a struct.

Previously, our logic when taking the address of an overloaded function
would not consider enable_if attributes, so long as all of the enable_if
conditions on a given candidate were true. So, two functions with
identical signatures (one with enable_if attributes, the other without),
would be considered equally good overloads. If we were calling the
function instead of taking its address, then the function with enable_if
attributes would be preferred.
This patch makes us prefer the candidate with enable_if regardless of if
we're calling or taking the address of an overloaded function.

match the feature set of the function that they're being called from.
This ensures that we can effectively diagnose some[1] code that would
instead ICE in the backend with a failure to select message.
Example:
__m128d foo(__m128d a, __m128d b) {
return __builtin_ia32_addsubps(b, a);
}
compiled for normal x86_64 via:
clang -target x86_64-linux-gnu -c
would fail to compile in the back end because the normal subtarget
features for x86_64 only include sse2 and the builtin requires sse3.
[1] We're still not erroring on:
__m128i bar(__m128i const *p) { return _mm_lddqu_si128(p); }
where we should fail and error on an always_inline function being
inlined into a function that doesn't support the subtarget features
required.

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
