--- Comment #8 from dave.anglin at bell dot net --- find_call_stack_args() is not called for sibcalls. It seemed at first that it needed to be called from mark_insn to mark the arguments of sibcalls but it can't handle arguments stored using the argument pointer and a similar use in the call pattern. It starting to look like I should just disable sibcalls on PA. Dave -- John David Anglin dave.ang...@bell.net
