Summary:
The clang used to pick up the qualifiers of the lamba's call operator
(which is always const) and fail to show non-const methods of 'this' in
completion results.

NetBSD intends to support only reentrant interfaces in interceptors.
When -lpthread is used without _REENTRANT defined, things are
not guaranteed to work.
This is especially important for <stdio.h> and sanitization of
interfaces around FILE. Some APIs have alternative modes depending
on the _REENTRANT definition, and NetBSD intends to support sanitization
of the _REENTRANT ones.

Add a simple method to query whether any sanitizer was enabled,
via SanitizerArgs. This will be used in the NetBSD driver to pass
additional definitions that are required by all sanitizers.

Avoid passing -faddrsig by default on NetBSD. This platform is still

Fix the sha2 interceptor macros to use a constant for array parameter
length rather than referencing the extern variable. Since the digest
length is provided in hash name, reuse the macro parameter for it.
Verify that the calculated value matches the one provided by system
headers.

The build.py script always runs the compiler in C++ mode, regardless of
the file extension. This results in mangled names presented to the
linker which in turn cannot find the printf symbol.
While we figure out how to solve this issue I've turned the source file
into a cpp file and added extern c. This should unbreak the bots.

Import libraries as created by llvm-dlltool always use the same archive

This change relaxes the requirements on the utility
`rewriteExprFromNumberToDuration` function, and introduces new checking

Without this patch, clang doesn't complain that X needs explicit data
sharing attributes in the following:
```
#pragma omp target teams default(none)
{
#pragma omp parallel num_threads(X)
;
}
```
However, clang does produce that complaint after the braces are
removed. With this patch, clang complains in both cases.

This patch aims to enable the tests for the compiler-rt builtin functions (that
currently already exist within compiler-rt) for PowerPC 64bit LE (ppc64le).
Previously when unit tests are run, these tests would be reported as
UNSUPPORTED. This patch updates the REQUIRES line for each test (to enable for
ppc64le), and each test is linked against compiler-rt when running.

Sibling patch to D55855, this emits UADD_SAT/USUB_SAT generic intrinsics for the SSE saturated math intrinsics instead of expanding to a IR code sequence that could be difficult to reassemble.

Now that we use the generic ISD opcodes, we can use the generic intrinsics directly as well. This fixes the poor fast-isel codegen by not expanding to an easily broken IR code sequence.
I'm intending to deal with the signed saturation equivalents as well.

Now that SimplifyDemandedBits/SimplifyDemandedVectorElts is simplifying vector elements, we're seeing more constant BUILD_VECTOR containing undefs.
This patch provides opt-in support for UNDEF elements in matchBinaryPredicate, passing NULL instead of the result ConstantSDNode* argument.
I've updated the (or (and X, c1), c2) -> (and (or X, c2), c1|c2) fold to demonstrate its use, which I believe is safe for undef cases.

urllib2 as been renamed into urllib and the library layout has changed.
Workaround that in a consistent manner.
Differential Revision: https://reviews.llvm.org/D55199
llvm-svn: 349627
As described on PR40091, we have several places where zext (and zext_vector_inreg) fold an undef input into an undef output. For zero extensions this is incorrect as the output should guarantee to least have the new upper bits set to zero.
SimplifyDemandedVectorElts is the worst offender (and its the most likely to cause new undefs to appear) but DAGCombiner's tryToFoldExtendOfConstant has a similar issue.
Thanks to @dmgreen for catching this.

This relands r330742:
"""
Let TableGen write output only if it changed, instead of doing so in cmake.
Removes one subprocess and one temp file from the build for each tablegen
invocation.
No intended behavior change.
"""
In particular, if you see rebuilds after this change that you didn't see
before this change, that's unintended and it's fine to revert this change
again (but let me know).
r330742 got reverted because some people reported that llvm-tblgen ran on every
build after it. This could happen if the depfile output got deleted without
deleting the main .inc output. To fix, make TableGen always write the depfile,
but keep writing the main .inc output only if it has changed. This matches what
we did in cmake before.

Using HI here makes no logical sense, since the dword is only

Thread Static Data cannot be used in early init on NetBSD
and FreeBSD. Reuse the ASan TSD API for compatibility with
existing code with an alternative implementation using Thread
Local Storage.
New version uses Thread Local Storage to store a pointer
with thread specific data. The destructor from TSD has been
replaced with a TLS destrucutor that is called upon thread
exit.

I tricked myself into thinking that deadlock detection is off by default in TSan by looking at the default value of the detect_deadlocks flag and outdated docs. (Created a pull request to update docs.)
I even managed to confuse others: https://groups.google.com/forum/#!topic/thread-sanitizer/xYvnAYwtoDk
However, the default value is overwritten in code (TSan_flags.cc:InitializeFlags). The TSan/deadlock tests also rely on this
This changes aligns the default value of the flag with the actual default behavior.

Currently spawnLldbMi accepts both lldb-mi options and executable to debug as
a single parameter. Split them.
As in D55859 we will need to execute one lldb-mi command before loading the
exe. Therefore we can no longer use the exe as lldb-mi command-line parameter
as then there is no way to execute a command before loading exe specified as
lldb-mi command-line parameter.
LocateExecutableSymbolFileDsym should be static, that is also a little
refactorization.
