Register Names

 

 

 

 

IA-64 registers are fully described in other documents. This appendix provides a list for convenience only. The register names are documented here as recognized by Ski and, in a few cases, don’t exactly match the names in other documents due to program limitations. For example, the floating point registers must be accessed in three pieces: the mantissa part, the sign part, and the (biased) exponent part. Similarly, the “Not a Thing” bits of the various registers are separate entities for Ski. Individual bits of complex registers such as the psr are documented here as well, corresponding to the names by which Ski recognizes them.
