844 the input and output values can be traced, along with the
845 instruction type. Make the -t option enable tracing.

7eebfc62
MM		 852 type of instruction this is. Count each of the types of

862 (sim_{trace,create_inferior}): Eliminate extraneous output unless
863 debugging.

870 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
871 (run): By default, the math library is not needed to be linked
872 in.
