[Qemu-devel] [PATCH 0/2] Guard page for code_gen_buffer

[Richard Henderson <rth@twiddle.net>]

I started down the path toward using this guard page to trigger
a restart of the translation for a given TB, but got hung up on
the win32 implementation of the "signal handler".

Nevertheless, just having the page without doing anything more
than crashing if it gets touched might still be useful.

Note that the new win32 path in the second patch is untested.
I thought I had a win7 vm on this laptop, but apparently not.
If someone else wants to do that this weekend, awesome.  Otherwise
I'll try to get to it when I'm home on Monday.

Thoughts?
