In 32b mode the reference count for block addresses
is not zero. This prevents inlining and constant
folding and causes the test to fail. Changing
the triple allows runnning the test in 64b mode.

The array in foo2 is now local instead of static until
at lower optimization levels the interprocedural constant
propagator is invoked before the global optimizer.

llvm r212077 causes this test to fail. We need to reorder some passes and
possibly make other changes to reenable the optimization being tested here.

Update the strategy in r212083 to try JIT first and otherwise fall back to the
interpreter. This gives the best of both worlds and still builds fine with no
targets enabled.

Requires supporting changes from LLVM r212086.

Fix the build when no targets are enabled. This dependency is incurred by two
unfortunate entries in LinkAllPasses.h included from cc1_main.cpp:

  llvm::createJumpInstrTablesPass();
  llvm::createCodeGenPreparePass();

Fixes the build when no targets are selected, or no native target is built.

This also better matches up with the description/title of the example and
demonstrates how clang can be used to run C++ on constrained environments
without file IO or executable memory permissions (e.g. iOS apps).

A comment is added explaining how to extend the demo with JIT support as
needed.

It used to be a feature of UBSan (it could sanitize a standalone
shared object instead of the whole program), but now it causes
more problems, like PR20165.

Add module dependencies (header files, module map files) to the list of
files to check when deciding whether to rebuild a preamble. That fixes
using preambles with module imports so long as they are in
non-overridden files.

My intent is to use to unify the existing dependency collectors to the
new “DependencyCollectory” interface from this commit, starting with the
DependencyFileGenerator.

This patch adds intrinsic __rdpmc to header file 'ia32intrin.h'.
Intrinsic __rdmpc can be used to read performance monitoring counters. It is
implemented as a direct call to __builtin_ia32_rdpmc.

It takes as input a value representing the index of the performance counter to
read. The value of the performance counter is then returned as a unsigned
64-bit quantity.

widespread problem.

Add sign checks to deal with the fact that IR parser line/column pairs are
signed integers and sometimes invalid.

The crash path is potentially triggered by corrupt '.bc' files in practice,
though I don't have a binary input test case that can be checked-in right now.

(Unfortunately the backend itself crashes on various ill-formed '.bc' inputs so
this bandage isn't as helpful as it appears yet.)

We'll want to share the implementation if anything else decides to check
for reserved names in future, so make this little snippet of code more
discoverable.

Also remove the __va_list_tag and __builtin_va_list special-case
checks. They're leftovers from before when the reserved name logic was
added.

No change in functionality.

Windows on ARM defines va_list as a typedef for char *.  Although the semantics
of argument passing for variadic functions matches AAPCS VFP, the wrapped
struct __va_list type is unused.  This makes the intrinsic definition for
va_list match that of Visual Studio.

This adds a linker tool for the Windows cygwin environment.  This linker
invocation is significantly different from the generic ld invocation.  It
requires additional parameters as well as does not accept some normal
parameters.  This should fix self-hosting on Cygwin.
