Ian Lance Taylor 5d8c099ede runtime: copy channel code from Go 1.7 runtime 
Change the compiler to use the new routines. Drop the separation of
    small and large values when sending on a channel. Allocate the select
    struct on the stack. Remove the old C implementation of channels. Adjust
    the garbage collector for the new data structure.
    
    Bring in part of the tracing code, enough for the channel code to call.
    
    Bump the permitted number of allocations in one of the tests in
    context_test.go. The difference is that now receiving from a channel
    allocates a sudog, which the C code used to simply put on the
    stack. This will be somewhat better when we port proc.go.

README 

See ../README.

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

This library should not be stripped when it is installed.  Go code
relies on being able to look up file/line information, which comes
from the debugging info using the libbacktrace library.

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

Directories:

go
  A copy of the Go library from http://golang.org/, with several
  changes for gccgo.

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