Is gdbreplay what I am looking for? >=20 > Not yet... ;-) A couple of years ago, you had posted a proposal about a gdb interface for reverse debugging http://sourceware.org/ml/gdb/2006-01/msg00013.html I guess this did not make it to GDB? Am I correct to understand that the efforts for GDB Reverse debugging are currently focused on teawater's GDB Record patch, which you guys=20 are helping with? To be honnest, I didn't look at the details of that patch (much too low level for me). However, I was wondering if it considers reverse debugging= =20 with a target (gdbserver or other stub?) From what I understand,=20 GDB Record, will record register and memory changes as they are made.=20=20 For some targets, storing all this may be prohibitive. I wondered if the recording is done by GDB on the host instead? Maybe I am going a little fast, already jumping to target reverse debugging? Thanks for you input marc =20
