Hi Richard, > I specifically want to test generic SVE rather than SVE tuned for a > specific core, so --with-arch=armv8.2-a+sve is the thing I want to test.
Btw that's not actually what you get if you use cc1 - you always get armv8.0, so --with-arch doesn't work at all. The only case that appears to work in cc1 is --with-cpu as long as it is not --with-cpu=native. Cheers, Wilco
