History
Richard Henderson 38bf819a5f compiler, reflect, runtime: Use static chain for closures. 
Change from using __go_set_closure to passing the closure
value in the static chain field.  Uses new backend support for
setting the closure chain in a call from C via
__builtin_call_with_static_chain.  Uses new support in libffi
for Go closures.

The old architecture specific support for reflect.MakeFunc is
removed, replaced by the libffi support.

All work done by Richard Henderson.

	* go-gcc.cc (Gcc_backend::call_expression): Add chain_expr argument.
	(Gcc_backend::static_chain_variable): New method.

README 

See ../README.

This is the runtime support library for the Go programming language.
This library is intended for use with the Go frontend.

The library has only been tested on GNU/Linux using glibc.  It should
not be difficult to port to other operating systems.

The library has only been tested on x86/x86_64 systems.  It should not
be difficult to port to other architectures.

Directories:

go
  A copy of the Go library from http://golang.org/, with a few
  changes for gccgo.  Notably, the reflection interface is different.

runtime
  Runtime functions, written in C, which are called directly by the
  compiler or by the library.

syscalls
  System call support.
