5 See the SPARC back-end for example (grep flag_stack_usage_info in sparc.c).
6 Once it is implemented, adjust SIZE below so that the stack usage for the
7 function FOO is reported as 256 or 264 in the stack usage (.su) file.
8 Then check that this is the actual stack usage in the assembly file. */
