Subject: DWARF location expressions considered harmful
Date: Mon, 12 Apr 2004 22:07:00 -0000 [thread overview]
Message-ID: <jewu4kkgt7.fsf@sykes.suse.de> (raw)
The introduction of DWARF location expressions has made debugging of
optimized code very difficult. Whenever a value is considered unavailable
by GDB the current operation is aborted immediately. This makes commands
like "info locals", "info args" or "info frame" pretty useless, because
there is no way to "skip" over those unavailable values to see the rest of
the information.
Andreas.
