1998-10-28 * sim-if.c (sim_do_command): Handle "sim info reg {bbpsw,bbpc}".Doug Evans2-152/+72
Bring over from branch.
1998-10-28For cygwin hosts, we need to use the return value from the readDrew Moseley1-0/+24
routine as the number of bytes to process. This apparently is due to text-mode vs binary-mode. If the mounts are done text-mode, then the size returnedby fstat() may be different than the number of bytes "read" in text mode.

across GDB and SIM directories.
