Eugene:  First thank you for your work on EGTBs.  Second, thanks for looking
into the IA-64 coding issues.  Had you considered the IA-64 instruction that
finds the first non-zero byte in operands of various sizes, and then using that
to index an 8-bit array?  Perhaps it is too slow vs your method with may exploit
more parallelism.


PS  Did you write vcinline.h for Crafty?
