Alp Toker 5853534b03 Attempt to fix the FreeBSD build, disable multiprocessing
Speculative quick fix based on clang-X86_64-freebsd output:

  File "/usr/local/lib/python2.6/multiprocessing/synchronize.py", line 33, in <module>
    " function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

NAKAMURA Takumi 7ef9ae1d43 clang/test/CodeGenCXX/debug-info-namespace.cpp: Suppress this also on msys, for now since r193116.
Clang confuses among dosish paths. In this case, "Input/foo.cpp" and "Input\foo.cpp" cannot be unified.

Jordan Rose e692cfa330 [analyzer] Don't emit an "Assuming x is <OP> y" if it's not a comparison op.
We could certainly be more precise in many of our diagnostics, but before we
were printing "Assuming x is && y", which is just ridiculous.

Introduce a new boolean setting enable-auto-oneliner

Peter Collingbourne 791e65dcfb Overhaul the symbolizer interface.
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps.  Those steps now always take place
together.

Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer.  Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.

The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.

Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.

Andrew Trick 57243da70f Fix SCEVExpander: don't try to expand quadratic recurrences outside a loop.
Partial fix for PR17459: wrong code at -O3 on x86_64-linux-gnu
(affecting trunk and 3.3)

When SCEV expands a recurrence outside of a loop it attempts to scale
by the stride of the recurrence. Chained recurrences don't work that
way. We could compute binomial coefficients, but would hve to
guarantee that the chained AddRec's are in a perfectly reduced form.

Partial fix for PR17459: wrong code at -O3 on x86_64-linux-gnu

ScalarEvolutionNormalization was attempting to normalize by adding and
subtracting strides. Chained recurrences don't work that way.

Rafael Espindola 7749d7ccc7 Handle calls and invokes in GlobalStatus.
This patch teaches GlobalStatus to analyze a call that uses the global value as
a callee, not as an argument.

With this change internalize call handle the common use of linkonce_odr
functions. This reduces the number of linkonce_odr functions in a LTO build of
clang (checked with the emit-llvm gold plugin option) from 1730 to 60.

Hal Finkel 02f562df43 LoopVectorizer: Don't attempt to vectorize extractelement instructions
The loop vectorizer does not currently understand how to vectorize
extractelement instructions. The existing check, which excluded all
vector-valued instructions, did not catch extractelement instructions because
it checked only the return value. As a result, vectorization would proceed,
producing illegal instructions like this:

  %58 = extractelement <2 x i32> %15, i32 0
  %59 = extractelement i32 %58, i32 0

where the second extractelement is illegal because its first operand is not a vector.

Added a new key that we understand for the "qHostInfo" packet: "default_packet_timeout:T;" where T is a default packet timeout in seconds.

This allows GDB servers with known slow packet response times to increase the default timeout to a value that makes sense for the connection.

Daniel Sanders 1b71f42f7d [bugpoint] Increase the default memory limit for subprocesses to 300MB.
Summary:
Currently shared library builds (BUILD_SHARED_LIBS=ON in cmake) fail three
bugpoint tests (BugPoint/remove_arguments_test.ll,
BugPoint/crash-narrowfunctiontest.ll, and BugPoint/metadata.ll).

If I run the bugpoint commands that llvm-lit runs with without -silence-passes
I see errors such as this:
    opt: error while loading shared libraries: libLLVMSystemZInfo.so: failed to
    map segment from shared object: Cannot allocate memory

It seems that the increased size of the binaries in a shared library build is
causing the subprocess to exceed the 100MB memory limit. This patch therefore
increases the default limit to a level at which these tests pass.

Jordan Rose 5565941eff Add -Wstring-plus-char, which warns when adding char literals to C strings.
Specifically, this warns when a character literal is added (using '+') to a
variable with type 'char *' (or any other pointer to character type). Like
-Wstring-plus-int, there is a fix-it to change "foo + 'a'" to "&foo['a']"
iff the character literal is on the right side of the string.

Daniel Jasper 33b909c5f3 clang-format: Adapt line break penalties for LLVM style.
Specifically make clang-format less eager to break after the opening
parenthesis of a function call.

Before:
  aaaaaaaaaaaaaaaaa(

      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
  aaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
                        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Apparently that is preferable. This penalties are adapted
conservatively, we might have to increase them a little bit further.
