asInteger()

const uint64_t& InstResult::asInteger ( ) const

inline

Explicit cast-like operations.

Definition at line 168 of file inst_res.hh.

asIntegerNoAssert()

const uint64_t& InstResult::asIntegerNoAssert ( ) const

Cast to integer without checking type.

This is required to have the o3 cpu checker happy, as it compares results as integers without being fully aware of their nature.
