Authentication-results: sourceware.org; auth=none

Hello,

I would like to update the gcc plugin API to include interfaces for
querying section size and alignment. The intent is to make it easier
for plugins to do link-time reordering of .bss/.data/.rodata sections
to reduce padding and/or improve cache utilization.

I've posted a patch to binutils that includes changes to the gold
linker to implement these hooks, you can find details at
http://sourceware.org/ml/binutils/2016-02/msg00400.html.

The attached patch is to make sure that the gcc plugin-api.h is in
sync with the corresponding header in binutils.

Questions + comments welcome.

Thanks, Than
