Ian Lance Taylor 03ac8302a6 runtime: enable precise GC checks when using stack maps
In the runtime there are bad pointer checks that currently don't
    work with the concervative collector. With stack maps, the GC is
    precise and the checks should work. Enable them.

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.
