Subject: [Bug c/19924] New: [AVR] MODES_TIEABLE incorrect
X-Bugzilla-Reason: CC
X-SW-Source: 2005-02/txt/msg01186.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

MODES_TIEABLE in avr is set such that access to subreg is prevented.

This result is significantly sub-optimal code.

Attached patch changes this. No regressions have been found with test suite -
indeed things got better!

Note this is related to PR/19815 documentation error.
