- Subject: [RFC] sim: Update sim_{fetch,store}_register for sh and mn10300
The patch below updates sim_fetch_register for both mn10300 and sh
to return the length of the value being fetched instead of -1. For
sh, sim_store_register() is changed in a like fashion.
This change is necessary due to past changes to remote-sim.c which do
more stringent checks of the return value.
Comments?
sim/mn10300/ChangeLog:
* interp.c (sim_fetch_register): Return length, not -1.
sim/ChangeLog:
* sh/interp.c (sim_store_register, sim_fetch_register): Return
length, not -1.
