The Go programming language
1b45cc45e3
Change two-bit stack map entries to encode: 0 = dead 1 = scalar 2 = pointer 3 = multiword If multiword, the two-bit entry for the following word encodes: 0 = string 1 = slice 2 = iface 3 = eface That way, during stack scanning we can check if a string is zero length or a slice has zero capacity. We can avoid following the contained pointer in those cases. It is safe to do so because it can never be dereferenced, and it is desirable to do so because it may cause false retention of the following block in memory. Slice feature turned off until issue 7564 is fixed. Update #7549 LGTM=rsc R=golang-codereviews, bradfitz, rsc CC=golang-codereviews https://golang.org/cl/76380043 |

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.
