* d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
output.
(_ins_type): New enumeration to specify which container an
instruction is in, and whether it is part of a parallel operation.
(_state): Add ins_type field.
({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
(ins_type_counters): Counters for the various instruction types.
({left,right}_nops): Counters for the number of nops in each
container.
(d10v_debug): New variable to indicate whether debugging is turned

function in the callback table.

instructions are done left first or right first.
(do_{long,2_short,parallel}): Indicate in the machine state which
type of instruction this is. Count each of the types of
instructions executed.

(run): By default, the math library is not needed to be linked
in.
({BFD,LIBIBERTY}_LIB): Define as variables so they can be

makes.
({run,callback}.o): Provide explicit paths to their appropriate
source directories.
(gencode{,.o},d10v-opc.o): Split compilation into creating object
and linking. Instead of linking in libopcodes.a, just compile

set the defaults.
(CC_FOR_BUILD): Deal with canadian crosses.
* configure: Regenerate.
