Fix a crash on release builds if gather intrinsics are passed a non-constant value for the last argument.

llvm-svn: 159501

Use a second switch statement to reduce number of calls to SelectGather in code. Reduces code size a bit.

No functionality change.

This behaves like the existing GNU __alignof and C++11 alignof keywords;
most of the patch is simply adding the third token spelling to various places.

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.

llvm-svn: 159483

re-used. Also, build in direct support for accumulating a set of lit
parameters, arguments, and testsuites to run as part of a 'check-all'
rule. This sinks 'check-all' from a Clang-specific construct to
a generic construct of the project.

Use getUniqueVRegDef.
Replace a loop with existing interfaces: modifiesRegister and readsRegister.
Factor out code into inline functions and simplify the code.

llvm-svn: 159470

In future changes we should:
* use __builtin_trap rather than derefing 'random' volatile pointers.
* avoid dumping temporary files into /tmp when running tests, instead
  preferring a location that is properly cleaned up by lit.

Added documentation for many of our python properties and also made the property help show up by declaring the properties correctly. We previosly declared properties into a local "x" variable, what I didn't realize is that the help will use this as the property name for the help output.

use template type diffing.

Also updated the internal manual and test cases for correctly keeping the bold
attribute and for tree printing.

Jordan Rose corrected me that this actually isn't needed.

When a local virtual register is made global, make sure to clear any
existing kill flags.

llvm-svn: 159461

This would previously get reported as the misleading "Virtual register
def doesn't dominate all uses."

llvm-svn: 159460

The solution is a bit inefficient: it creates N checkers, one for each check, and
each check does a dispatch on the function name.  This is redundant, but we can fix
this once we have the proper ability to enable/disable subchecks.
