* reg-stack.c (compensate_edge): Correct mistake in the assertion
checking of EDGE_ABNORMAL_CALL edges; complex return values can
result in the top two stack slots, st(0) and st(1), being live.

(compensate_edge): Clean-up. Perform as little work as possible
when src and dest stacks match. Avoid modifying block_info.
Reorder and simplify assertion checks. Avoid unnecessary copying
of regstack structure.
(convert_regs_1): Set the done flag here...
(convert_regs_2): ... instead of here.

* reg-stack.c (starting_stack_p): New static global.
(straighten_stack): Delete prototype. Change to update the stack
before the current insn.
(subst_stack_regs): Update call to straighten stack.
(emit_swap_insn): Delete prototype. For the first insn in a
basic block, update stack_in instead of emitting a real swap.
(change_stack): When changing the stack before the first insn
in a basic block, update stack_in instead of emitting real code.
(compensate_edges): Clear starting_stack_p during compensation.
(convert_regs_1): Keep track of starting_stack_p whilst processing
a basic block.

the destination. This routine is now only called when this is safe.
(better_edge): New function split out from convert_regs_1 to
determine which of two edges is better to propagate across.
(convert_regs_1): We need only search for a best edge if the
stack layout hasn't been defined yet. Use better_edge to help
find beste. No longer traverse unnecessary edges.

(propagate_stack): New function to copy the stack layout
at the start of a basic block from the layout at the end of
one of its predecessors.
(compensate_edge): Assume that both source and destination
blocks have already had their stack layouts defined.
(compensate_edges): Traverse all non-entry edges in the CFG
and call compensate_edge on each in turn.
(convert_regs_1): Change return type to void. Call
propagate_stack instead of compensate_edge.
(convert_regs_2): Change return type to void. Update call
to convert_regs_1 to ignore the (now void) return value.
(convert_regs): Update calls to convert_regs_2 to ignore
the (now void) return value. After all the basic blocks have
been processed, call compensate_edges to actually emit new
insns.
(reg_to_stack): Initialize the aux info for each basic block
with FOR_EACH_BB instead of which FOR_EACH_BB_REVERSE.

from comments.
