This patch just gets rid of some write-only operand_alternative fields,
which makes things easier for the later patches to preprocess_constraints.
Richard
gcc/
* recog.h (operand_alternative): Remove offmem_ok, nonffmem_ok,
decmem_ok and incmem_ok. Reformat other bitfields for consistency.
* recog.c (preprocess_constraints): Update accordingly.
