There is an oddity that I don't understand with this code (when it does work).
It looks like if a probe containing a statement_num does have dwarf info then it
gets registered through query_func_info (i->entrypc, *i, q); which calls
query_statement() as follows:
if (fi.prologue_end != 0)
{
query_statement (fi.name, fi.decl_file, fi.decl_line,
&fi.die, fi.prologue_end, q);
}
else
{
query_statement (fi.name, fi.decl_file, fi.decl_line,
&fi.die, entrypc, q);
}
But that seems wrong. Why is it using the prologue_end or entrypc of the
function in which the statement is instead of the value of the statement num itself?
