            Bug ID: 23849
           Summary: stapbpf script caching
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bpf
          Assignee: systemtap at sourceware dot org
          Reporter: me at serhei dot io
  Target Milestone: ---

Known issues preventing enabling caching for stapbpf:

- cached module name is very long, current trace_printk() output method must
include it in string literals, rapidly exhausting stack space -- depends on
PR22330
- current caching code assumes C compilation (e.g. tries to copy nonexistent C
file)

--- Comment #1 from Serhei Makarov <me at serhei dot io> ---
note that this is needed to speedup tracepoint querying for pr23866 (since it
involves C code generation even with the BPF backend)
