Description Frank Ch. Eigler 2006-04-26 14:35:57 UTC 
There are several bugs with statement("...") handling in tapsets.cxx.
Comment 1 Frank Ch. Eigler 2008-02-23 02:30:59 UTC 
patch committed for summary bug (prologue processing should be bypassed)
still need patch for stmt address verification
Comment 2 Frank Ch. Eigler 2008-05-27 17:08:18 UTC 
Solving this the brute force way may involve
- finding the function that contains the given PC address
- finding that function's set of (source) line records
- iterating across them to find a matching pc

This would restrict statement(NUM) probes to a source-level
statement/line.  Restricting them finer, to instruction
granularity, would probably require piecemeal disassembly,
which I'd rather avoid if possible.
