Bill Seurer 8be14f11ce [PowerPC] This revision adds 68 of the missing "Predefined Functions for Vector Programming" from appendix A of the OpenPOWER ABI for Linux Supplement document.
I also added tests for the new functions and updated another test that was looking for specific line numbers in error messages from altivec.h.

Bill Schmidt 41e14c4dfa [PPC64] Add vector pack/unpack support from ISA 2.07
This patch adds support for the following new instructions in the
Power ISA 2.07:

  vpksdss
  vpksdus
  vpkudus
  vpkudum
  vupkhsw
  vupklsw

These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces.  These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.

The first three instructions perform saturating pack operations.  The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated.  The other
instructions are only generated via built-in support for now.

I noticed during patch preparation that the macro __VSX__ was not
previously predefined when the power8-vector or direct-move features
are requested.  This is an error, and I've corrected that here as
well.

Appropriate tests have been added.

There is a companion patch to llvm for the rest of this support.

Richard Smith 23d8d0338e [modules] Fix a #include cycle when building a module for our builtin headers.
xmmintrin.h includes emmintrin.h and vice versa if SSE2 is enabled. We break
this cycle for a modules build, and instead make the xmmintrin.h module
re-export the immintrin.h module. Also included is a fix for an assert in the
serialization code if a module exports another module that was declared later
in the same module map.

Dmitri Gribenko a586ea13a4 Restore the libc++ definition of max_align_t on Apple platforms
Clang has introduced ::max_align_t in stddef.h in r201729, but libc++ was
already defining std::max_align_t on Darwin because there was none in the
global namespace.  After that Clang commit though, libc++ started defining
std::max_align_t to be a typedef for ::max_align_t, which has a different
definition.  This changed the ABI.  This commit restores the previous
definition.

Bill Schmidt cad3a5f7d4 [PATCH][Power] Fix (and deprecate) vec_lvsl and vec_lvsr for little endian
The use of the vec_lvsl and vec_lvsr interfaces are discouraged for
little endian targets since Power8 hardware is a minimum requirement,
and Power8 provides reasonable performance for unaligned vector loads
and stores.  Up till now we have not provided "correct" (i.e., big-
endian-compatible) code generation for these interfaces, as to do so
produces poorly performing code.  However, this has become the source
of too many questions.

With this patch, LLVM will now produce compatible code for these
interfaces, but will also produce a deprecation warning message for
PPC64LE when one of them is used.  This should make the porting direction
clearer to programmers.  A similar patch has recently been committed to
GCC.

This patch includes a test for the warning message.  There is a companion
patch that adds two unit tests to projects/test-suite.

When building with modules enabled, we were defining max_align_t as a typedef

once in the same modules-enabled compilation of C11 or C++11 code.

Akira Hatanaka 416efb5f90 Fix bugs in cpuid.h.
This commit makes two changes:

- Remove the push and pop instructions that were saving and restoring %ebx
  before and after cpuid in 32-bit pic mode. We were doing this to ensure we
  don't lose the GOT address in pic register %ebx, but this isn't necessary
  because the GOT address is kept in a virtual register.

- In 64-bit mode, preserve base register %rbx around cpuid.

This fixes PR20311 and rdar://problem/17686779.

Saleem Abdulrasool c68237bc2c Driver: bifurcate extended and basic MSC versioning
This restores the original behaviour of -fmsc-version. The older option
remains as a mechanism for specifying the basic version information. A
secondary option, -fms-compatibility-version permits the user to specify an
extended version to the driver.

The new version takes the value as a dot-separated value rather than the
major * 100 + minor format that -fmsc-version format. This makes it easier to
specify the value as well as a more flexible manner for specifying the value.

Specifying both values is considered an error.

The older parameter is left solely as a driver option, which is normalised into
the newer parameter. This allows us to retain a single code path in the
compiler itself whilst preserving the semantics of the old parameter as well as
avoid having to determine which of two formats are being used by the invocation.

The test changes are due to the fact that the compiler no longer supports the
old option, and is a direct conversion to the new option.

Nico Weber 272bcf6768 Let stddef.h respect __need_{wchar_t, size_t, NULL, ptrdiff_t, wint_t}.
glibc expects that stddef.h only defines a single thing if either of these
defines is set.  For example, before this change, a C file containing

  #include <stdlib.h>
  int ptrdiff_t = 0;

would compile with gcc but not with clang. Now it compiles with clang too.

This also fixes PR12997, where older versions of the Linux headers would define
NULL incorrectly, and glibc would define __need_NULL and expect stddef.h to
redefine NULL with the correct definition.

Daniel Jasper 2f0f297bdb Revert r201734 and r201742.
This breaks backwards compatibility with existing code. Previously, this
was defined as

  #define _mm_prefetch(a, sel) (__builtin_prefetch((void *)(a), 0, (sel)))

Which basically accepts any pointer. Changing this to char* simply
breaks a lot of existing code. I have tried changing char* to
"const void*", which seems to be the right thing as per Intel
specification this should work on basically any pointer. However,
apparently this breaks windows compatibility (because of a conflicting
declaration in windows.h).

So, we probably need to #ifdef this based on whether clang is compiling
for windows. According to Chandler, this might be done by introducing an
additional symbol to a fake type in BuiltinsX86.def and then condition
the type expansion on the platform.

Warren Hunt 40d6f29ad8 Add _mm_prefetch and some others as MS builtins
This patch adds several built-ins that are required for ms 
compatibility. _mm_prefetch must be a built-in because it takes a 
compile-time constant argument and our prior approach of using a #define 
to the current built-in doesn't work in the presence of re-declaration 
of _mm_prefetch. The others can be obtained by including the windows 
system headers. If a user includes the windows system headers but not 
intrin.h they still need to work and therefore must be built-in because 
we don't get a chance to implement them in intrin.h in this case.

Chandler Carruth e813984b43 Teach Clang to provide ::max_align_t in C11 and C++11 modes.
This definition is not chosen idly. There is an unfortunate reality with
max_align_t -- the specific nature of its definition leaks into the ABI
almost immediately. Because it is part of C11 and C++11 it becomes
essential for it to match with other systems on that ABI. There is an
effort to discourage any further use of this construct as a consequence
-- using max_align_t introduces an immediate ABI problem. We can never
update it to have larger alignment even as the microarchitecture changes
to necessitate higher alignment. =/

The particular definition here exactly matches the ABI of GCC's chosen
::max_align_t definition, for better or worse. This was written with the
help of Richard Smith who was decoding the exact ABI implications of the
selected definition in GCC. Notably, in-register arguments are impacted
by the particular definition chosen. =/

No one is under the illusion that this is a "good" or "useful"
definition of max_align_t, and we are working with the standards
committee to specify a more useful interface to address this need.

Ted Kremenek b79ee57080 Implemented delayed processing of 'unavailable' checking, just like with 'deprecated'.
Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.

This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings.  By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent.  It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.

This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated".  It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
 (e.g., "function" instead of "destructor").  By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away.  This diagnostic can likely be further wordsmithed
to be shorter.

Richard Smith 2362829734 tl;dr: Teach Clang to work around g++ changing its workaround to glibc's
implementation of C99's attempt to control the C++ standard. *sigh*


The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX,
should not be defined when the header is included in C++ mode, unless
__STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard
says "Thanks, but no thanks" and C11 removed this rule, but various C library
implementations (such as glibc) follow C99 anyway.

g++ prior to 4.8 worked around the C99 / glibc behavior by defining
__STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is
supposed to provide these macros too. g++ 4.8 works around it by defining
__STDC_*_MACROS in its builtin <stdint.h> header.

This change makes Clang act like g++ 4.8 in this regard: our <stdint.h> now
countermands any attempt by the C library to implement the undesired C99 rules,
by defining the __STDC_*_MACROS first. Unlike g++, we do this even in C++98
mode, since that was the intent of the C++ committee, matches the behavior
required in C11, and matches our built-in implementation of <stdint.h>.

Richard Smith 8acb4044d8 libstdc++'s <cstdalign> #includes <stdalign.h> and expects it to guard against
being included in C++. Don't define alignof or alignas in this case. Note that
the C++11 standard is broken in various ways here (it refers to the contents
of <stdalign.h> in C99, where that header did not exist, and doesn't mention
the alignas macro at all), but we do our best to do what it intended.

Jordan Rose 8ba0fba28a Use %clang_cc1 so that the test works even if the target isn't available.
Xcode-style clang builds only support Xcode's architectures, so mips
isn't available and the driver tries to use gcc instead. cc1 will go
ahead and do -fsyntax-only for any platform it knows about even if it
can't actually compile.

David Blaikie 83261063d1 Fix tests that weren't actually verifying anything.
Passing -verify to clang without -cc1 or -Xclang silently passes (with a
printed warning, but lit doesn't care about that). This change adds -cc1 or,
as is necessary in one case, -Xclang to fix this so that these tests are
actually verifying as intended.

I'd like to change the driver so this kind of mistake could not be made, but
I'm not entirely sure how. Further, since the driver only warns about unknown
flags in general, we could have similar bugs with a misspellings of arguments
that would be nice to find.
