Re: [PATCH for 3.2] Make PDP-11 port compilable
Your method for pre_modify failed with a following message.
../../gcc-3.2-pdp11port/gcc/unwind-dw2-fde.c:299: output_operand: invalid expression as operand
It stops just before printing the -(sp).
BTW, I put back to use "movb" for the pre_modify and
added post_modify entry. But I wonder whether gcc will
use the post_modify entry or not. As far as I know,
gcc does not use pop operation unless the recovering of
the frame pointer.
