pa.c (output_function_prologue): Pass the highest register number saved for ENTRY_GR and ENTRY_FR directives...
* pa.c (output_function_prologue): Pass the highest register
number saved for ENTRY_GR and ENTRY_FR directives rather
than the number of registers saved.
(hppa_expand_prologue): Account for %r4 when it's being
used as a frame pointer.
