Bug ID: 29633
Summary: [display text] Support derived metrics
Product: binutils
Version: 2.39
Status: NEW
Severity: enhancement
Priority: P2
Component: gprofng
Assignee: vladimir.mezentsev at oracle dot com
Reporter: ruud.vanderpas at oracle dot com
Target Milestone: ---
Very often, derived metrics provide more insight. For example, to normalize
certain events against the number of instructions executed.
Similar to what is already done for the IPC and CPI derived metrics, the user
should have the possibility to include the division of two columns in the
output. Multiple of such derived metrics should be supported.
This brings up a UI issue how the user can pass this on. Possibly by expanding
the metric definition with the two metrics to be divided. For example
e.cyclesDIVinsts.
By using an operator, like DIV here, we can also support other basic arithmetic
operators.
