expression parsing with odd line separator char

[Nick Clifton]

Hi Alan,

: gas/ChangeLog
: 	* 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.

Approved.

Cheers
