multiple failures on amd64 ««« original CL description runtime: introduce helper persistentalloc() function It is a caching wrapper around SysAlloc() that can allocate small chunks. Use it for symtab allocations. Reduces number of symtab walks from 4 to 3 (reduces buildfuncs time from 10ms to 7.5ms on a large binary, reduces initial heap size by 680K on the same binary). Also can be used for type info allocation, itab allocation. There are also several places in GC where we do the same thing, they can be changed to use persistentalloc(). Also can be used in FixAlloc, because each instance of FixAlloc allocates in 128K regions, which is too eager.

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.
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.
