This CL changes the encoding used for the Go symbol table, stored in the binary and used at run time. It does not change any of the semantics or structure: the bits are just packed a little differently. The comment at the top of runtime/symtab.c describes the new format. Compared to the Go 1.0 format, the main changes are: * Store symbol addresses as full-pointer-sized host-endian values. (For 6g, this means addresses are 64-bit little-endian.) * Store other values (frame sizes and so on) varint-encoded. The second change more than compensates for the first: for the godoc binary on OS X/amd64, the new symbol table is 8% smaller than the old symbol table (1,425,668 down from 1,546,276). This is a required step for allowing the host linker (gcc) to write the final Go binary, since it will have to fill in the symbol address slots (so the slots must be host-endian) and on 64-bit systems it may choose addresses above 4 GB.

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.html in your web browser.
After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

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.
