««« CL 179980043 / d71cc7e8a0e0 runtime: remove assumption that noptrdata data bss noptrbss are ordered and contiguous The assumption can be violated by external linkers reordering them or inserting non-Go sections in between them. I looked briefly at trying to write out the _go_.o in external linking mode in a way that forced the ordering, but no matter what there's no way to force Go's data and Go's bss to be next to each other. If there is any data or bss from non-Go objects, it's very likely to get stuck in between them. Instead, rewrite the two places we know about that make the assumption. I grepped for noptrdata to look for more and didn't find any. The added race test (os/exec in external linking mode) fails without the changes in the runtime. It crashes with an invalid pointer dereference. Fixes #9133.

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
