Typical use case: execution trace of some code which is

This can be loading of a linux kernel module, a user space
application or kernel code which handles a rare event.
I can enable logging and single stepping before that code
starts. There is no need to re-translate existing TBs:
they are faster than TBs with only single steps, so only
the execution of the new code is slow, and only new TBs
will appear in qemu.log which is exactly what I want.
Typically, I use single stepping like this to examine a
problem with QEMU's emulation or code generation. Two examples:
some years ago aptitude crashed in mips emulation (fpu emulation
problem), and now I use it to examine differences between
native TCG and TCI (tiny code interpreter).
What is that TCI???
Thanks,
