AFAICT gdb doesn't have existing machinery to allow for undefined pieces of a value. Perhaps one way to do this would be to add a new field to struct value, which would be a bitmap tracking which bits are known to be valid. Then, things like field lookups could preserve this. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |tromey at redhat dot com Status|UNCONFIRMED |NEW Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2009-03-22 01:03:03 date| | http://sourceware.org/bugzilla/show_bug.cgi?id=9977 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
