25% PowerPC code size increase since last September?

[Peter Dufault]

In updating the Phytec MPC5554 to this mornings build I see a large code size increase.  It will no longer fit in the 2MB FLASH on the MPC5554, which is a problem.  Here are the sizes of the binaries, the first one built two days ago against the RTEMS in September and the second one using the identical user code base and this morning’s RTEMS.  I haven’t done much to analyze this yet other than to verify it’s still being built with the same optimization flags.

-rwxrwxr-x 1 pjd usergrp 1624684 Jun 26 09:42 fw.bin.gcc4.8.2
-rwxrwxr-x 1 pjd usergrp 2017220 Jun 28 10:48 fw.bin

Has anyone else noticed this?  Does anyone regularly monitor the size of the test suite binaries to watch for changes?  Are there new options that should be set to disable new features that add size overhead?

I’ll start looking through the maps to see if it is new code or the compiler, the compiler has gone from 4.8.2 to 4.9.2.
