cmd/go: pass plugin package name to compile -p

2017-09-01T18:27:59Z

When compiling a plugin, package main gets a new name so as not to conflict with the main package in the host binary, or any other plugins. It is already defined by cmd/go, and used by cmd/link when filling out the "" package placeholder in symbols. With this CL, the plugin-specific name for main is also passed to cmd/compile's -p flag. This is used to fill out the pkgpath field of types, and ensures that two types defined in two different plugin mains with the same name will not be mistaken for one another at runtime.

cmd/link: support plugins with no exported symbols

2016-11-01T20:56:30Z

A plugin with no exported symbols is still potentially very useful. Its init functions are called on load, and it so it can have visible side effects.
