machmode.h (SCALAR_INT_MODE_P): New macro to test for scaler integer mode (MODE_INT or MODE_PARTIAL_INT).
* machmode.h (SCALAR_INT_MODE_P): New macro to test for
scaler integer mode (MODE_INT or MODE_PARTIAL_INT).
* explow.c (trunc_int_for_mode): Abort when the mode is not
a scaler integer mode.
* combine.c (expand_compound_operation): Don't expand Vector
or Complex modes into shifts.
(expand_field_assignment): Don't do bitwise arithmatic and
shifts on Vector or Complex modes.
(simplify_comparison): Don't call trunc_int_for_mode
for VOIDmode.
* recog.c (general_operand): Likewise.
(immediate_operand): Likewise.
(nonmemory_operand): Likewise.
