Bug in Binutils 2.15 for the H8300H ?

["Hansjuergen Dreuth" <hansjuergen dot dreuth at simplify-technologies dot de>]

Hi,

recently I upgraded our GNU toolchain for use with the H8/300h and
H8/300s microcontrollers.
When using the binutils 2.15 the errors shown in the following example
assembler file occurred. They do not happen if binutils 2.14 are used:
----------------------------------------------------

.h8300h		;directive for h8300h code
.equ NUMBER, 0x80
.equ NUMBER2, 0x70

; 1st error:
    AND.B	 #~NUMBER, r3l   ; this causes: "Error: invalid operands"
    AND.B	 #~0x0F, r3l	 ; this works
    AND.B	 #~NUMBER2, r3l  ; this also works (error seem to depend on the
        ; number - the most significant bit seems to be the problem)

; 2nd error (does not occur when ".h8300s" is chosen; but the h8300h also
; has this instruction and address mode). The following warning and error
; are issued: Warning: Opcode `bclr' with these operand types not
; available in H8/300H mode ; Error: invalid operands

    bclr  #6, @0xFFFFFF7C ; clear RDRF

-----------------------------------------------------------------------

Does anybody know what causes these errors and how to correct them ?

Thanks,

Hansjuergen Dreuth
