| * | Use Info Table Provenances to decode cloned stack (#18163) | Sven Tennie | 2021-09-23 | 1 | -6/+121 |
| | | | | | | | | | | | | | | | | | Emit an Info Table Provenance Entry (IPE) for every stack represeted info table if -finfo-table-map is turned on. To decode a cloned stack, lookupIPE() is used. It provides a mapping between info tables and their source location. Please see these notes for details: - [Stacktraces from Info Table Provenance Entries (IPE based stack unwinding)] - [Mapping Info Tables to Source Positions] Metric Increase: T12545 | ||||
| * | Introduce stack snapshotting / cloning (#18741) | Sven Tennie | 2021-09-23 | 1 | -0/+103 |
| Add `StackSnapshot#` primitive type that represents a cloned stack (StgStack). The cloning interface consists of two functions, that clone either the treads own stack (cloneMyStack) or another threads stack (cloneThreadStack). The stack snapshot is offline/cold, i.e. it isn't evaluated any further. This is useful for analyses as it prevents concurrent modifications. For technical details, please see Note [Stack Cloning].
