[Qemu-devel] [PATCH] i386: fix breakpoints handling in icount mode

[Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>]

This patch fixes instructions counting when execution is stopped on
breakpoint (e.g. set from gdb). Without a patch extra instruction is translated
and icount is incremented by invalid value (which equals to number of
executed instructions + 1).
