Abstract:

A method is described comprising inserting an allocation instruction within a routine if a function call instruction is found within the routine. Another method is described comprising inserting multiple allocation instructions within a routine by searching for one or more functional characteristics within the routine and inserting an allocation instruction within the routine if a functional characteristic is discovered. Another method is described comprising performing a first allocation for a first amount of register space at the entry block of a routine and then performing a second allocation for a second amount of register space for the live information within the routine at the time of the second allocation. Then, performing a function call to a second routine and performing a third allocation for a third amount of register space at the entry block of the second routine, the third amount of register space and the first amount register space having a common register.

Abstract:

An apparatus for measuring the ovality, concentricity and runout of an engine valve seat which is comprised of a datum plate, an air gage head, a pot master, a compressed air source, a signal processing device, and a display unit. The compressed air source, signal processing device and the display unit are conventional. One characteristic feature of the invention is the datum plate for limiting the angular displacement of the air gage head during a measurement of an engine valve seat. A second characteristic feature of the invention is that the air gage head "floats" in the air gage body if a measurement is within an established limit for the measurement. A third characteristic feature of the invention is a self-aligning pilot at an end portion of the gage head.
