Hello!
This patch generalizes register class check, no other functional changes.
2013-08-01 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.h (MAYBE_NON_Q_CLASS_P): New.
* config/i386/i386.c (ix86_secondary_reload): Use INTEGER_CLASS_P and
MAYBE_NON_Q_CLASS_P where appropriate.
Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.
Uros.
