c-typeck.c (c_expand_start_case): Return immediately if exp is an ERROR_MARK.
1999-08-27 00:27 -0700 Zack Weinberg <zack@bitmover.com>
* c-typeck.c (c_expand_start_case): Return immediately if exp
is an ERROR_MARK.
* fold-const.c (operand_equal_p): Return immediately if arg1
or arg0 are ERROR_MARKs.
* stor-layout.c (layout_type [case RECORD_TYPE]): Ignore
fields of type ERROR_MARK when calculating if the record can
go in a register.
