2000-06-01 Alan Modra <alan@linuxcare.com.au>
* expr.c (operand): Test is_end_of_line outside switch to catch
line separator chars that are also operators.
(operator): Return O_illegal for line separator chars.
* read.c (is_end_of_line): Use 1 instead of 99. Don't set `;'
entry (or `!' entry for TC_HPPA).
* config/tc-arm.c (my_get_float_expression): Cast to unsigned char
before indexing is_end_of_line. Remove redundant check for '\0'.
(fp_op2): Likewise.
* config/tc-h8500.c (md_assemble): Likewise.
* config/tc-mcore.c (md_assemble): Likewise.
* config/tc-tic30.c (tic30_find_parallel_insn): Likewise.
(md_atof): Likewise
* config/tc-m88k.c (s_bss): Cast to unsigned char before indexing
is_end_of_line.
* config/tc-mcore.c (mcore_cons): Likewise.
(mcore_float_cons): Likewise.
(mcore_stringer): Likewise.
* config/tc-tic30.c (tic30_find_parallel_insn): Likewise.
2000-06-01 Scott Bambrough <scottb@netwinder.org>
* config/tc-arm.c (do_mrs): Allow SPSR_BIT to be set correctly.
