2011-05-04 Andreas Krebbel <Andreas.Krebbel@de.ibm.com>
* calls.c (emit_library_call_value_1): Invoke
promote_function_mode hook on libcall arguments.
* explow.c (promote_function_mode, promote_mode): Handle TYPE
argument being NULL.
* targhooks.c (default_promote_function_mode): Lisewise.
* config/s390/s390.c (s390_promote_function_mode): Likewise.
* config/sparc/sparc.c (sparc_promote_function_mode): Likewise.
* doc/tm.texi: Document that TYPE argument might be NULL.
