[ANNOUNCEMENT] LLVM/Clang 5.0.1
Fri Jan 5 06:31:00 GMT 2018
The following packages have been uploaded to the Cygwin distribution:
The LLVM Core libraries provide a modern source- and target-independent
optimizer, along with code generation support for many popular CPUs.
These libraries are built around a well specified code representation
known as the LLVM intermediate representation.
Clang is an LLVM native C/C++/ObjC compiler, which aims to deliver
amazingly fast compiles, extremely useful error and warning messages and
to provide a platform for building great source level tools.
compiler-rt provides a simple library that provides an implementation of
the low-level target-specific hooks required by code generation and
other runtime components.
libc++ is a new implementation of the C++ standard library, targeting C++11.
This is an update to the latest upstream stable release of the
LLVM/Clang toolchain, with several improvements for Cygwin:
* Clang has been modified to properly link with ld on Cygwin, bypassing
GCC executables entirely while matching its behaviour. GCC's libraries
and startup files are still required.
* compiler-rt is now available as an experimental alternative to
libgcc's builtins implementation; it can be used with clang
-rtlib=compiler-rt. Please note that libgcc_s (or libgcc_eh with
-static) will still be used for exception handling support.
* libc++/libc++abi are now available as an experimental alternative to
libstdc++; it can be used with clang++ -stdlib=libc++.
* Clang's unwind.h has been fixed for SEH.
* The OCaml bindings for LLVM have been re-enabled, with new
dependencies. They have not been tested.
* Unfortunately, lld could not be added at this time due to lack of
GNU-style command-line support in its COFF driver. It appears that may
be changing for 6.0.
