- targets that define PREFERRED_STACK_BOUNDARY more aligned than
- STACK_BOUNDARY (e.g. x86), or if not all registers can be pushed
- (e.g. x86 fp regs) which would ordinarily have to be implemented
- as a sub/mov pair due to restrictions in calls.c.
-
- Propagation stops when any of the insns that need adjusting are
- (a) no longer valid because we've exceeded their range, (b) a
- non-trivial push instruction, or (c) a call instruction.
-
- Restriction B is based on the assumption that push instructions
- are smaller or faster. If a port really wants to remove all
- pushes, it should have defined ACCUMULATE_OUTGOING_ARGS. The
