Before this patch we would only use the fist occurance of a matcher
function in the documentation, for example leaving out
hasType(Matcher<QualType>).

1. Move internal functions into ASTMatchersInternal.
2. Adapt dump_ast_matchers.py to the new VariadicOperatorMatcherFunc
signature.
3. Update the actual docs with the updated tool / code.

The isPure() CXXMethodDecl matcher matches pure method declaration like "A::x"
in this example:
class A {
virtual void x() = 0;
}

In 'obsequi' we have a scop in which the current dead code elimination works,
but the generated code is way too complex. To avoid this trouble (and to not
disable the DCE entirely) we add an additional approximative step before
the actual dead code elimination. This should fix one of the two current
nightly-test issues.
Polly could be improved to handle 'obsequi' by teaching it to introduce only a
single parameter for (%1 and zext %1) which halves the number of parameters and
allows polly to derive a simpler representation for the set of live iterations.
However, this needs some time to investigate.
I will commit a test case as soon as we have a reduced one.

Fix an unintentional stdin read in the darwin-asan-nofortify.c test and replace
it with an explicit test for multiple -E inputs passed to the driver.
Noticed while working on the in-process driver patch.

Most 64-bit targets define int64_t as long int, and AArch64 should
make same definition to follow LP64 model. In GNU tool chain, int64_t
is defined as long int for 64-bit target. So to get consistent with GNU,
it's better Changing int64_t from 'long long int' to 'long int',
otherwise clang will get different name mangling suffix compared with g++.

We still don't use the PGO to set branch weights for these loops, but at
least this keeps the compiler from crashing. <rdar://problem/16137778>

The .error directive is similar to .err in that it will halt assembly if it is
evaluated for assembly. However, it permits a user supplied message to be
rendered.

The .ifeqs directive assembles the following code if the quoted string
parameters are equal. The strings must be quoted using double quotes.

Sven suggested to use this simpler code generation strategy as the convex_hull
computation is apparently rather inefficient. We do not have a test case that
shows a difference, but, in case we find a test case where this makes a
difference, we can reconsider our decission.

- Only include offsets with local (in function scope) symbols, where we don't encode scoping
- Only include the filename with non-system symbols. Presumably the system headers will not provide conflicting definitions.

.align is handled specially on certain targets. .align without any parameters
on ARM indicates a default alignment (4). Handle the special case in the target
parser, but fall back to the generic parser for the normal version.

The .ifne directive assembles the following section of code if the argument
expression is non-zero. Effectively, it is equivalent to if.
llvm-svn: 201986
If the strings are not quoted, the first string stops at the first comma, and
the second string stops at the end of the line. Strings which contain
whitespace should be quoted. Unquoted space is to be discarded.
llvm-svn: 201985
The .err directive produces an error whenever it is assembled. This can be
useful for preventing assembly when an unexpected condition occurs.
llvm-svn: 201984
In case we do not have valid dependences, we do not run dead code elimination or
the schedule optimizer. This fixes an infinite loop in the dead code
elimination (PR12110).

Before this patch they would take an boolean argument to say if the path
already existed. This was redundant with the returned error_code which is able
to represent that. This allowed for callers to incorrectly check only the
existed flag instead of first checking the error code.
Instead, pass in a boolean flag to say if the previous (non-)existence should be
an error or not.
Callers of the of the old simple versions are not affected. They still ignore
the previous (non-)existence as they did before.

The LLVMSupport library implementation consolidates all dependencies on
system libraries. Move the logic gathering system libraries out of
'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'.
Use the target_link_libraries() command there to tell CMake about the
link dependencies of the LLVMSupport implementation. CMake will
automatically propagate this to all targets that link LLVMSupport
directly or indirectly.
We still need to build knowledge of system library dependencies into
'llvm-config'. Store the list of libraries needed in a property on
LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it
from there.
Drop all calls to 'link_system_libs' and 'get_system_libs' from our
CMake code. Replace their implementations with a warning that explains
the calls are no longer necessary. Also drop from 'LLVMConfig.cmake'
the HAVE_* and related variables that were published there only to allow
'get_system_libs' to run outside our build process.

This adds support for the .short and its alias .hword for adding literal values
into the object file. This is similar to the .word directive, however, rather
than inserting a value of 4 bytes, adds a 2-byte value.
