Cover letter [Qemu-devel] [PATCH 0/3] Alternative post-instruction early TB termination
Originally I was hoping to get my whole debugger patch series on the track, but I'm still stuck with a bug in the x86 debug register support (weird single step race, triggered by dr-usage). So let's start smaller with a friction of that series.
These patches introduce a new single step mode that allows the emulator to generate and execute only a single-instruction TB, but without triggering a debug event afterwards. This is exploited by tb_invalidate_phys_page[_range] and later on by the watchpoint subsystem (patch to be posted). This should also allow to remove cflags from TranslationBlock, as done by the third patch.
