Hello! ... to make a couple of trivial cleanups. 2012-08-04 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.h (QI_REGNO_P): New define. (ANY_QI_REGNO_P): Ditto. (GENERAL_REGNO_P): Use IN_RANGE macro. (QI_REG_P): Use QI_REGNO_P. (ANY_QI_REG_P): Use GENERAL_REGNO_P and QI_REGNO_P. (HARD_REGNO_CALLER_SAVE_MODE): Use QI_REGNO_P. * config/i386/i386.c (ix86_hard_regno_mode_ok): Ditto. (x86_extended_QIreg_mentioned_p): Ditto. Also check if register is a general register. Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN. Uros.
