i386.c (override_options): Replace ABI_STACK_BOUNDARY with MIN_STACK_BOUNDARY.
2008-08-01 H.J. Lu <hongjiu.lu@intel.com>
* config/i386/i386.c (override_options): Replace ABI_STACK_BOUNDARY
with MIN_STACK_BOUNDARY.
(ix86_update_stack_boundary): Likewise.
(ix86_expand_prologue): Assert MIN_STACK_BOUNDARY instead of
STACK_BOUNDARY.
* config/i386/i386.h (ABI_STACK_BOUNDARY): Renamed to ...
(MIN_STACK_BOUNDARY): This.
