branches. Predicated off IPREL branches that were predicted as taken will be
counted as wrong path outcomes.
— Weight
Fraction of IPREL branches among all branch types.
— Correct
Percentage of correctly predicted IPREL branches.
— Wrong Path
Percentage of IPREL branches for which the target path (taken/not-taken) was
predicted incorrectly.
— Wrong Target
Percentage of IPREL branches for which the target address was predicted
incorrectly.
• Indirect
This metric provides the branch prediction outcome breakdown (correct, wrong
path, wrong target) for indirect branches. This includes both indirect calls and
general indirect branches. Predicated off indirect branches that were predicted as
taken will be counted as wrong path outcomes.
— Weight
Fraction of Indirect branches among all branch types.
— Correct
Percentage of correctly predicted Indirect branches.
— Wrong Path
Percentage of Indirect branches for which the target path (taken/not-taken) was
predicted incorrectly.
— Wrong Target
Percentage of Indirect branches for which the target address was predicted
incorrectly.
• Return
This metric provides the branch prediction outcome breakdown (correct, wrong
path, wrong target) for return branches. Predicated off returns that are predicted
as taken will be counted as wrong path outcomes.
— Weight
Fraction of Return branches amongst all branch types.
— Correct
Percentage of correctly predicted Return branches.
