Well, there is documentation in the internals manual, of course. Each bit in each entry in REG_CLASS_CONTENTS corresponds to a particular register. Which register it means is target specific, but you can figure it out based on, e.g., REGISTER_NAMES. For example, for the i386, bit 0 is ax, bit 1 is dx, etc. Ian
