* module/statprof.scm (<state>): Instead of a boolean count-calls?, treat the presence of a call-counts hash table as indicating a need to count calls. That hash table maps callees to call counts. A "callee" is either the IP of the entry of a program, the symbolic name of a primitive, or the identity of a non-program. New members "buffer" and "buffer-pos" replace "procedure-data". We try to avoid analyzing things at runtime, instead just recording the stack traces into a buffer. This will let us do smarter things when post-processing. (fresh-buffer, expand-buffer): New helpers. (fresh-profiler-state): Adapt to <state> changes. (sample-stack-procs): Instead of updating the procedure-data table (which no longer exists), instead trace the stack into the buffer. (count-call): Update to update the call-counts table instead of the procedure-data table. (statprof-start, statprof-start): Adapt to call-counts change. (call-data): Move lower in the file. Add "name" and "printable" members, and no longer store a proc. (source->string, program-debug-info-printable, addr->pdi) (addr->printable): New helpers. (stack-samples->procedure-data): New procedure to process stack trace buffer into a hash table of the same format as the old procedure-data table. (statprof-fold-call-data, statprof-proc-call-data): Use stack-samples->procedure-data instead of procedure-data. (statprof-call-data->stats): Adapt to count-calls change. (statprof-display, statprof-display-anomalies): Adapt. |
