Based on the last comment, should this PR be closed. It has been five years.

The size regression occurs with 4.3.x but with trunk today I see a size
reduction to 992 bytes which is in the ball park of the original size.

Test code to demonstrate the size increase

A short C file that compiles to about 60% larger with the new compiler, command
line options can be find in the file itself

I attached this code earlier for you to
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31849 along with size reports for
various optimization levels (Os, O1, and O2) and gcc versions.  Is this a dupe
of that PR or separate?  Can someone familiar with 31849 make a ruling?
