Alexey Bataev cc37cc1db2 [OPENMP] Codegen for "omp flush" directive.
For each "omp flush" directive a call to "void kmpc_flush(ident_t *, ...)" function is generated.
Directive "omp flush" may have an associated list of variables to flush, but currently runtime function ignores them. So the patch generates just "call kmpc_flush(ident_t *<loc>, i32 0)".

Jordan Rose 08b3638b84 [CMake] Use .svn/wc.db as our VC dependency if it's available.
In order to keep SVNVersion.inc from being regenerated on every build, we need
to specify as a dependency a file that only changes when the VC state updates.
I previously just had .svn/entries, but that's only used by Subversion 1.6.
1.7 uses .svn/wc.db instead; prefer that if it's present.

(Thanks, Nico!)

Alexey Samsonov cfb97aa620 Remove support for undocumented SpecialCaseList entries.
"global-init", "global-init-src" and "global-init-type" were originally
used to blacklist entities in ASan init-order checker. However, they
were never documented, and later were replaced by "=init" category.

Old blacklist entries should be converted as follows:
  * global-init:foo -> global:foo=init
  * global-init-src:bar -> src:bar=init
  * global-init-type:baz -> type:baz=init

Jordan Rose 85216ef0c3 [CMake] Always include the Clang repo version, just like the autoconf build.
Now that LLVM's helper script GetSVN.cmake actually works consistently,
there's no reason not to use it. We avoid having to regenerate SVNVersion.inc
every time by marking it as dependent on Git's reflog or SVN's entries file.

This should end most of the issues of the AST format changing and breaking
old module files: CMake-Clang should now detect that the version changed just
like Autoconf-Clang has.

Based on r190557. Depends on LLVM r222391.

Jordan Rose c1800d2524 [CMake] Update GetSVN.cmake to use LLVM version control helper scripts.
This allows the logic to work with Git, and also uses the variable names

This is a re-application of r190556 and r190808. This changes the interface
of GetSVN.cmake. Clang change to follow.

Andrea Di Biagio 1b657bfcc8 [X86] Improved lowering of v4x32 build_vector dag nodes.
This patch improves the lowering of v4f32 and v4i32 build_vector dag nodes
that are known to have at least two non-zero elements.

With this patch, a build_vector that performs a blend with zero is 
converted into a shuffle. This is done to let the shuffle legalizer expand
the dag node in a optimal way. For example, if we know that a build_vector
performs a blend with zero, we can try to lower it as a movq/blend instead of
always selecting an insertps.

This patch also improves the logic that lowers a build_vector into a insertps
with zero masking. See for example the extra test cases added to test sse41.ll.

Lang Hames 56c0eb2d90 [ADT] Fix PR20728 - Incorrect APFloat::fusedMultiplyAdd results for x86_fp80.
As detailed at http://llvm.org/PR20728, due to an internal overflow in
APFloat::multiplySignificand the APFloat::fusedMultiplyAdd method can return
incorrect results for x87DoubleExtended (x86_fp80) values. This commonly
manifests as incorrect constant folding of libm fmal calls on x86. E.g.

fmal(1.0L, 1.0L, 3.0L) == 0.0L      (should be 4.0L)

This patch fixes PR20728 by adding an extra bit to the significand for
intermediate results of APFloat::multiplySignificand, avoiding the overflow.

Frederic Riss dce60a747c Fix a temporary MDNode leak.
While emitting debug information for function forward decalrations, we
create DISubprogram objects that aran't stored in the AllSubprograms
list, and thus won't get finalized by the DIBuilder. During the DIBuilder
finalize(), the temporary MDNode allocated for the DISubprogram
Variables field gets RAUWd with a non temporary DIArray. For the forward
declarations, simply delete that temporary node before we delete the
parent node, so that it doesn't leak.

Tom Stellard e0ddfd11ea R600/SI: Make SIInstrInfo::isOperandLegal() more strict
A register operand that has a common sub-class with its instruction's
defined register class is not always legal.  For example,
SReg_32 and M0Reg both have a common sub-class, but we can't
use an SReg_32 in instructions that expect a M0Reg.

This prevents the llvm.SI.sendmsg.ll test from failing when the fold
operand pass is added.
