builtins.c (expand_builtin_longjmp): A longjmp can be a call too.
2001-05-22 Andrew MacLeod <amacleod@redhat.com>
* builtins.c (expand_builtin_longjmp): A longjmp can be a call too.
* config/ia64/ia64.md (nonlocal_goto): Reverse label and frame pointer
parameters to __ia64_nonlocal_goto. Flag as NO_RETURN.
* config/ia64/ia64.c (ia64_expand_epilogue): Make sure we are issuing
"r2" to the assembly file. Only issue allocs with non-zero parameters.
