[1.] gcc -O0 assembly arch/x86/kvm/emulate.c gets compilation failure --

[2.] Full description of the problem/report:
I'm trying to compile this file at -O0, but gcc chokes in register allocation
at the inline assembly.
In the ordinary Linux build, this file compiles with gcc at -O2, without
compilation errors.
Compiling with -O0 is not really expected to work (although -O1 *is*),
although what you are reporting is an actual bug ("+a" : "a" should
either be "+a" or "=a" : "a").
