Ian Lance Taylor 24f1d7f80e runtime: print C functions in traceback 
Since gccgo can trace back through C code as easily as Go code, we
    should print C functions in the traceback.
    
    This worked before https://golang.org/cl/31230 for a dumb reason.  The
    default value for runtime.traceback_cache was, and is, 2 << 2, meaning
    to print all functions.  The old C code for runtime_parsedebugvars
    would return immediately and do nothing if the environment variable
    GODEBUG was not set (if GODEBUG was set it would later call
    setTraceback.  The new Go code for runtime.parsedebugvars does not
    return immediately if GODEBUG is not set, and always calls
    setTraceback.  Either way, if GOTRACEBACK is not set, setTraceback
    would set traceback_cache to 1 << 2, meaning to only print non-runtime
    functions and having the effect of not printing plain C functions.
    
    Keep the current handling of GODEBUG/GOTRACEBACK, which matches the gc
    library, but add an extra check to print C functions by default.

VERSION

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.
