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)
