PR32302: Emit forward decls within tracepoint_derived_probe_group() too
|
|
|
|
Forward decls added in commit 069def0ae9184 need to actually be
|
|
emitted in 2 locations, roughtly corresponding to where
|
|
tracepoint_extra_decls() is used.
|
|
|
|
It would be ideal to put them directly to tracepoint_extra_decls()
|
|
but that gives significantly less recognized tracepoints.
|
|
|
|
The plan is toreview this again though and try to merge the
|
|
tracepoint_forward_decls() body into tracepoint_extra_decls()
|
|
if possible.
