New Revision: 149517

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=149517
Log:
        PR rtl-optimization/40667
        * defaults.h (MINIMUM_ALIGNMENT): Define if not defined.
        * doc/tm.texi (MINIMUM_ALIGNMENT): Document it.
        * config/i386/i386.h (MINIMUM_ALIGNMENT): Define.
        * config/i386/i386.c (ix86_minimum_alignment): New function.
        * config/i386/i386-protos.h (ix86_minimum_alignment): New prototype.
        * cfgexpand.c (expand_one_var): Use MINIMIM_ALIGNMENT.
        * emit-rtl.c (gen_reg_rtx): Likewise.
        * function.c (assign_parms): Likewise.  If nominal_type needs
        bigger alignment than FUNCTION_ARG_BOUNDARY, use its alignment
        rather than passed_type's alignment.
