Not to be outdone: Simics, at www.virtutech.com, also has support for reverse
debug with gdb, using our own patched version of gdb 6.8. This has been in use
since 2005.

Simics is free for academia, if you are an academic, and we are also quite happy
to provide access to Simics licenses to the gdb maintainers. We are looking into
how to integrate the upcoming reversible gdb with our backend, looks fairly
similar.

Best regards,
