goupx - Fix golang Linux ELF executables to work with upx
Update: 2016/03/10
As far as I (pwaller) know, goupx is no longer necessary for Linux binaries since it was fixed in go1.6.
About
Installation: go get github.com/pwaller/goupx
(or if you don't want to do it with root, GOPATH=${HOME}/.local go get github.com/pwaller/goupx
will install it to ${HOME}/.local/bin/goupx
).
Usage: goupx [filename]
Fixes the PT_LOAD
offset of [filename] and then runs upx
.
This is only necessary for Linux ELF executables (not Mach-O executables or windows binaries, for example).
Based on code found on the upx bugtracker.

Typical compression ratio
Resulting filesizes are typically 25% of the original go executable. Your mileage my vary.
