Fixed for the difference of Cygwin with other Windows variants (MSVC,
Itanium, MinGW).
- The platform name is renamed to "cygwin" from "windows" which is used
for searching the standard libraries.
- The consideration for DLL storage class (DllExport/DllImport) is not
required for Cygwin and MinGW. There is no problem when linking in
these environment.
- Cygwin should use large memory model as default.(This may be changed
if someone ports to 32bit)
- Cygwin and MinGW should use the autolink feature in the sameway of
Linux due to the linker's limit.
Add initial support for modelling DLL Storage semantics for global values. This
is needed to support the indirect addressing mechanism used on Windows.
Properly lower reference counting SIL instructions with nonatomic attribute as invocations of corresponding non-atomic reference counting runtime functions.
Each runtime function definition in RuntimeFunctions.def states which calling convention
should be used for this runtime function. But IRGen and LLVMPasses were not always
properly propagating this declared calling convention all the way down to llvm's Call instructions.
In many cases, the standard C convention was set for the call irrespective of the actual calling
convention defined for a given runtime function. As a result, incorrect code was generated.
This commit tries to fix all those places, where such a mismatch was found. In many cases this is
achieved by defining a helper function CreateCall in such a way that makes sure that the call instruction
gets the same calling convention as the one used by its callee operand.
Make use of the re-usable functionality provided by IRGen. This ensures that LLVM IR generated by IRGen and
LLVMPasses for runtime functions declarations or wrappers is always in sync.

can be strength reduced to retain. same for unknownRelease and release.

some of the ARC entry points. rdar://22724641. After this commit,
swift_retain_noresult will be completely replaced by swift_retain.
LLVMARCOpts pass is modified NOT to rewrite swift_retain to
swift_retain_noresult which forward no reference.

After this commit, swift_retain will return no reference and LLVMARCContract pass is modified NOT to rewrite
swift_retain_noresult to old swift_retain which forwarded the reference.

to remove reference forwarding for some of the ARC entry points. rdar://22724641. After this
commit, swift_retain_noresult will be completely replaced by swift_retain and LLVMARCOpts.cpp
will no longer canonicalize swift_retain to swift_retain_noresult as now swift_retain returns no
reference.
Swift SVN r32058
to remove reference forwarding for some of the ARC entry points. rdar://22724641. After this
commit, swift_retain will be the same as swift_retain_noresult, returning no reference.
LLVMARCContract pass is also modified NOT to rewrite swift_retain_noresult to the
old swift_retain which forwards the reference.
