Ian Lance Taylor fbe9724cc3 runtime: fixes for -buildmode=c-archive
With -buildmode=c-archive, initsig is called before the memory
    allocator has been initialized.  The code was doing a memory
    allocation because of the call to funcPC(sigtramp).  When escape
    analysis is fully implemented, that call should not allocate.  For
    now, finesse the issue by calling a C function to get the C function
    pointer value of sigtramp.
    
    When returning from a call from C to a Go function, a deferred
    function is run to go back to syscall mode.  When the call occurs on a
    non-Go thread, that call sets g to nil, making it impossible to add
    the _defer struct back to the pool.  Just drop it and let the garbage
    collector clean it up.

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.
