Manman Ren 72098b2c91 Added assertion in getVRegDef of MachineRegisterInfo to make sure the virtual

to use getUniqueVRegDef instead of getVRegDef.

Chandler Carruth 5da53436d5 Convert the uses of '|&' to use '2>&1 |' instead, which works on old
versions of Bash. In addition, I can back out the change to the lit
built-in shell test runner to support this.

This should fix the majority of fallout on Darwin, but I suspect there
will be a few straggling issues.

Dmitri Gribenko 3292d06a1b Add a new libclang completion API to get brief documentation comment that is
attached to a declaration in the completion string.

Since extracting comments isn't free, a new code completion option is
introduced.

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

Chandler Carruth 665c76bc52 The built-in shell test runner for some reason doesn't like the quoting
and multi-line nature of this test. I don't really feel like bugging
this kind of edge-case, so just put it on one line and use single
quotes. With this, every test *really* passes with the built-in shell
test runner.

Chandler Carruth 872ac7cfad Fix the TCL-style quoting in one random test that somehow slipped
through my perl nets.

Chandler Carruth a5a29f970e Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

Chandler Carruth 0a4a261365 Make tests which first provide a negative assertion via 'not', then
a pipeline, and then a positive assertion via grep, use two RUN lines
instead.

Supporting these complex ideas of 'success' and 'failure' across
multiple stages of a pipeline is brittle in the shell world, and would
block switching to ShTest format; it only worked due to contrivances
introduced by the TclTest format.

Writing this as two separate RUN lines seems clearer in any event.

This is another step toward completely removing TclTests from lit.

Chandler Carruth ae00a80869 Rewrite three tests that had truly egregious abuses of 'grep' in them to
use FileCheck.

Aside from removing a dependence on TCL-style quoting, this also makes
the tests ... significantly more robust. =] It would be really, *really*
great of the maintainer(s) of the CellSPU backend went through and
systematically rewrite these tests to use FileCheck. There are a lot
more that have nearly this bad of abuses.

Another step along the path to a TclTest-free testsuite.

Chandler Carruth 8bdfe1ec92 Switch a bunch of Linker tests from using elaborate echo productions to
just provide and reference separate input files from an Inputs
subdirectory. This pattern works very well in the Clang tree and is
easier to understand in my opinion. It also has fewer limitations and
will remove one particularly annoying use of TCL-style {} quoting from
the testsuite.

Also teach the LLVM lit configuration to avoid recursing into 'Inputs'
subdirectories. This wasn't required for the previous 'Inputs'
subdirectories used due to fortuitous suffix patterns.

This is the first step to completely removing support for TCL-style tests.

Meador Inge cfb6090912 PR13189: va_list broken with precompiled headers
For some targets a structure named __va_list_tag is built to help define
the __builtin_va_list type.  However, __va_list_tag was not being treated as a
predefined type thus causing problems when serializing the AST.  This commit
fixes that oversight by adding the necessary support to treat __va_list_tag
as a predefined type.

Chandler Carruth 8a6290721e Switch Clang to use the new common LLVM CMake infrastructure for adding
lit testsuites. This sinks all management of the aggregate lit runs into
the LLVM CMake files, making Clang only responsible for declaring its
own testsuite. In the process we fix numerous "bugs" where the proper
method of invoking lit has changed over time, and the old system
encoded several broken artifacts of this in ABIs and compatibility
tests.

It also switches to 'check-clang' for the canonical name of the test
suite, although 'clang-test' remains as an alias.

The situation when Clang is being built in standalone mode is little
changed. It replicates just enough of the lit setup to cope with the
oddities of being run outside of an LLVM build.

rule. This sinks 'check-all' from a Clang-specific construct to
a generic construct of the project.
