Hi All,
After calling create_bounce_frame , how does the execution return to
the next instruction ? I mean the following line:
movb  $0,TRAPBOUNCE_flags(%edx)
I my understanding , the returning path is : create_bounce_frame ->
guest os exception handler -> interrupted place
It seems that execution will not return to the above line . Maybe I
have missed something , can someone point it out for me ? All my
discussions assume x86_32.

BR
