These are somewhat arbitrary tests that check if "thing goes fine" when
processing various platform-specific headers.

Also move warn-sysheader.cpp to Misc where the other diagnostics infrastructure
tests live.

File moves only.

operations on the call graph. This one forms a cycle, and while not as
complex as removing an internal edge from an SCC, it involves
a reasonable amount of work to find all of the nodes newly connected in
a cycle.

Also somewhat alarming is the worst case complexity here: it might have
to walk roughly the entire SCC inverse DAG to insert a single edge. This
is carefully documented in the API (I hope).

Add support for the remaining hints from the ACLE.  Although __dbg is listed as
a hint, it is handled different, so it is not covered by this change.

Windows on ARM uses AAPCS, but has some deviations.  wchar_t remains an unsigned
short on WoA, which does not conform to AAPCS.  Ensure that wchar_t is defined
accordingly.

Both MinGW and cygwin (i686) construct export directives without the global
leader prefix.  This is mostly due to the fact that they use GNU ld which does
not correctly handle the export directive.  This apparently has been been broken
for a while.  However, this was recently reported as being broken by
mingwandroid and diorcety of the msys2 project.

Remove the global leader prefix if targeting MinGW or cygwin, otherwise, retain
the global leader prefix.  Add an explicit test for cygwin's behaviour of export
directives.

llvm-svn: 207926

Create a helper function to generate the export directive.  This was previously
duplicated inline to handle export directives for variables and functions.  This
also enables the use of range-based iterators for the generation of the
directive rather than the traditional loops.  NFC.

We don't modify the AttrBuilder in AttributeSet::get, make the reference

This fix simply ensures that both metadata nodes are path-aware before
performing path-aware alias analysis.

This issue isn't normally triggered in LLVM, because we perform an autoupgrade
of the TBAA metadata to the new format when reading in LL or BC files. This
issue only appears when a client creates the IR manually and mixes old and new
TBAA metadata format.

This fixes <rdar://problem/16760860>.

* Fixes a "return" that was indented at the same level as the continuation
  from the previous line
* Wrap several lines to 80 columns
* Remove an if check that was always true
* Move a variable declaration slightly closer to its use

The fix itself is fairly simple: move getAccessVariant to MCValue so that we
replace the old weak expression evaluation with the far more general
EvaluateAsRelocatable.

This then requires that EvaluateAsRelocatable stop when it finds a non
trivial reference kind. And that in turn requires the ELF writer to look
harder for weak references.

Last but not least, this found a case where we were being bug by bug
compatible with gas and accepting an invalid input. I reported pr19647
to track it.
