Hello,
I would like to ask a question regarding "BreakpointHitCallback", which is
declared as such:
bool (*BreakpointHitCallback)(void *baton,
StoppointCallbackContext *context,
lldb::user_id_t break_id,
lldb::user_id_t break_loc_id);
Is there any particular reason that "break_id" and "break_loc_id" are of type
"user_id_t" (64-bit unsigned) instead of "break_id_t" (32-bit signed), which is
used both for "Stoppoint::m_bid" and "StoppointLocation::m_loc_id"?
This causes an issue mainly with internal breakpoints, since the callback of an
internal breakpoint with (ID == 0xfffffffe) is called with (break_id ==
0xfffffffffffffffe), forcing the callback to cast the argument back to a 32-bit
signed in order to use it correctly, e.g. when the IDs are stored and need to
be looked up.
A small example attempting to illustrate the problem:
