1998-01-23First round of d10v ABI changesMichael Meissner2-68/+78
1998-01-22 * interp.c (UMEM_SEGMENTS): New define, set to 128.Fred Fish2-54/+134
(sim_size): Use UMEM_SEGMENTS rather than hardwired constant. (sim_close): Reset prog_bfd to NULL after closing it. Also reset prog_bfd_was_opened_p after closing prog_bfd. (sim_load): Reset prog_bfd_was_opened_p after closing prog_bfd. (sim_create_inferior): Get start address from abfd not prog_bfd. (xfer_mem): Do bounds checking on addresses and return zero length read/write on bad addresses, rather than aborting. Prepare to be able to handle xfers that cross segment boundaries, but not yet implemented. Only emit debug message when d10v_debug is set as well as DEBUG being defined.
