Adam Nemet 286ae08e7d Implement AVX1 vbroadcast intrinsics with vector initializers
These intrinsics are special because they directly take a memory operand (AVX2
adds the register counterparts).  Typically, other non-memop intrinsics take
registers and then it's left to isel to fold memory operands.

In order to LICM intrinsics directly reading memory, we require that no stores
are in the loop (LICM) or that the folded load accesses constant memory
(MachineLICM).  When neither is the case we fail to hoist a loop-invariant
broadcast.

We can work around this limitation if we expose the load as a regular load and
then just implement the broadcast using the vector initializer syntax.  This
exposes the load to LICM and other optimizations.

At the IR level this is translated into a series of insertelements.  The
sequence is already recognized as a broadcast so there is no impact on the
quality of codegen.

_mm256_broadcast_pd and _mm256_broadcast_ps are not updated by this patch
because right now we lack the DAG-combiner smartness to recover the broadcast
instructions.  This will be tackled in a follow-on.

There will be completing changes on the LLVM side to remove the LLVM
intrinsics and to auto-upgrade bitcode files.

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.

Warren Hunt 20e4a5d2af Reapply 201734 but with appropriate gcc compatibility
Because GCC incorrectly defines _mm_prefetch to take anything that casts 
to void*, people have started using that behavior.  The previous patch 
that made _mm_prefetch actually take a const char * broke compatibility 
with existing code.  This update to the patch leaves the macro that 
defines _mm_prefetch with the (void*) cast when _MSC_VER is not defined.

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.

bit_<foo> constants for the various feature bits as described in version 039
(May 2011) of Intel's SDM Volume 2 in the description of the CPUID
instruction.  The list of bit_<foo> constants is a bit exhaustive (GCC
doesn't do near this many).  More bits could be added from a newer version of

Richard Smith 49e56440f9 Add missing include guards into headers in lib/Headers. While it may appear
that these headers should not be included more than once, they are in fact
included twice when building our builtins module (in order for it to generate
submodules for them), and without this, any modular build enabling AVX and
including any builtin header fails.

Testing this is tricky because including any of these headers in a modular
build is liable to fail, due to unrelated builtin headers in the same module
including headers which might not be available on the system running the tests.
Suggestion on that front are welcome (but we're getting close to being able to
run a buildbot that has modules enabled for all tests, which would nicely solve
the testing problem).

Reid Kleckner 7ab75b3f68 Avoid names like __in that conflict with SAL in builtin headers
Microsoft's Source Annotation Language (SAL) defines a bunch of keywords
for annotating the inputs and outputs of functions.  Empty definitions
for the keywords are provided by <stdlib.h> -> <crtdefs.h> -> <sal.h>.
This makes it basically impossible to include MSVC's stdlib.h and
Clang's *mmintrin.h headers at the same time if they have variables
named __in.  As a workaround, I've renamed those variables.

This fixes the Modules/compiler_builtins.m test which was XFAILed,
presumably due to this conflict.

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>.

Argyrios Kyrtzidis fff55a028b [lib/Headers] Break the module import cycle between _Builtin_intrinsics.sse and _Builtin_intrinsics.sse2
Module "sse" implicitly exports module "sse2".
This is bad because we also have module "sse2" export module "sse" (as intended) so we end up with a cycle
in the module import graph:
1. sse2 -> (also imports) sse
2. sse -> (also imports) sse2

To eliminate the cycle remove 2.; importing module "sse2" will also import module "sse", but just importing
module "sse" will not also import module "sse2".

Clang's <stddef.h> provides definitions for the C standard library
types size_t, ptrdiff_t, and wchar_t. However, the system's C standard
library headers tend to provide the same typedefs, and the two
generally avoid each other using the macros
_SIZE_T/_PTRDIFF_T/_WCHAR_T. With modules, however, we need to see
*all* of the places where these types are defined, so provide the
typedefs (ignoring the macros) when modules are enabled.

begining with an underscore followed by an uppercase letter for any use.

I think I got them all, but open to being corrected. For the most part I
didn't bother updating function-like macro parameter names because I don't
believe they're subject to any such collission - though some function-like
macros already follow this convention (I didn't update them in part because
the churn was more significant as several function-like macros use the double
underscore prefixed version of the same name as a parameter in their
implementation)
