Hi,
While doing a test run with the minimum supported compiler I found:
An old gcc 3.3-hammer segfaults when compiling the current KVM emulate.c (or rather in x86_emulate_insns) on x86-64.
The compiler goes into an endless recursion in validate_rtx and then eventually overflows the stack and dies.
I minimized a test case, but didn't find a workaround (minimized test case http://halobates.de/emulate-min.i)
My guess it's related to some of the inline assembler uses.
This might be an excuse to bump the minimum compiler version again.
