[PATCH 09/14] x86: emit exception test after each JNI call

JNI methods can signal exceptions but those exceptions are not technically thrown until JNI method returns to JIT code. We must therefore test for exceptions signalled by JNI methods upon return. This test is cheap for non-exceptional flow but is expensive in the other case. Signed-off-by: Tomek

[PATCH 08/14] x86: fix bug in native_call()

The stack pointer was not restored after call because %ecx is always 0 after arguments are copied because it's decremented by 'rep movsb'. This also optimizes argument copying by using movsd instead of movsb. Signed-off-by: Tomek Grabiec --- arch/x86/include/arc
