David Schultz f365db00e5 Mark all inline asms that read the floating-point control or status ... registers as volatile. Instructions that *wrote* to FP state were already marked volatile, but apparently gcc has license to move non-volatile asms past volatile asms. This broke amd64's feupdateenv at -O2 due to a WAR conflict between fnstsw and fldenv there.		2005-01-14 07:09:23 +00:00
