We have done some preliminary "smoke testing" at Virtutech to see how gdb-main-branch revexec works with our old proven revexec engine. The resul= ts are quite encouraging. Simple testing using gdb-remote to talk to Simics, with Power Architecture = and ARM targets appears to work. What worked in our specially-patched gdb-6.8 version now works with gdb-trunk. We can stop and reverse and step etc. Essentially, this indicates that the reverse execution core support is OK.= =20 We also tested using MI commands to drive reverse execution. We used gdb-tr= unk plus our proposed MI commands, and the only problem we ran into seems to be= the same reverse-finish (or preferably, uncall) operation that Teawater and Marc have been reporting. Once again, the system seems to be working fine overal= l.=20 Best regards, /jakob _______________________________________________________ Jakob Engblom, PhD, Technical Marketing Manager Virtutech=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 Direct: +46= 8 690 07 47=A0=A0=A0 Drottningholmsv=E4gen 22=A0=A0=A0=A0=A0 Mobile: +46 709 242 646=A0=A0 11243 Stockholm=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 Web:=A0=A0=A0 www.virtu= tech.com=A0 Sweden ________________________________________________________ =A0=20
