compiler, libgo: don't pad sparc64-linux epollevent

Change the compiler to not add zero padding because of zero-sized
fields named "_", since those can't be referenced anyhow.

Change the sparc-linux64 epollevent struct to name the alignment
field "_", to avoid zero padding.

A Go frontend

Ian Lance Taylor Last update 15 June 2014

This is a compiler frontend for the Go programming language. The frontend was originally developed at Google, and was released in November 2009. It was originally written by Ian Lance Taylor.

It was originally written for GCC. As of this writing it only supports GCC, but the GCC support has been separated from the rest of the frontend, so supporting another compiler is feasible.

The go subdirectory holds the frontend source code. This is mirrored to the gcc/go subdirectory in the GCC repository.

The libgo subdirectory holds the library source code. This is a copy of the main Go library with various changes appropriate for this compiler. The main Go library is hosted at http://go.googlesource.com/go, in the src directory. The libgo subdirectory is mirrored to the libgo subdirectory in the gcc repository.
