Detailed Description

template<class Impl>
struct BaseDynInst< Impl >::Regs

Collect register related information into a single struct.

The number of source and destination registers can vary, and storage for information about them needs to be allocated dynamically. This class figures out how much space is needed and allocates it all at once, and then trivially divies it up for each type of per-register array.
