New information:
The function readint() in peep.c complains because it gets the string
'[_ptr_rx]'.
This is not just with rrc, but also with and, or, ld. Also with numeric address:
and a,[0x6000]
or a,[0x6000]
ld a,[0x6000]
I have an easy work-around for "rrc [_ptr_rx]" so I am not stuck.
ldw x,_ptr_rx
rrc (x)
The assembler seems to be happy with the syntax:
00011E C6 50 06 [ 1] 266 ld a, 0x5006
000121 A4 20 [ 1] 267 and a, #(1 << 5)
000123 AB FF [ 1] 268 add a, #255
000125 CE 00 34 [ 2] 269 ldw x, _ptr_rx
000128 76 [ 1] 270 rrc (x)
000129 72 36 00 34 [ 4] 271 rrc [_ptr_rx]
It seems that the peephole optimizer does not like this addressing mode.
Anything I can do to help?
Thanks,
