Since both FPU registers are 32-bit we can store them in the 64-bit fenv_t to make handling the bits easier. While there add FE_DENORMAL, which also exists on x86. Also make sure that whenever we are being passed an exception mask, we only allow the bits that are supported by hardware. Found by regression tests Debugged with Moritz Buhl ok kettenis@ Update floating point header to better represent 64-bit ARM. 2017-01-11T00:18:22Z patrick patrick@openbsd.org 2017-01-11T00:18:22Z urn:sha1:16c759471ee4e502b99c19d52d1f1aae297631c4 Import of OpenBSD/arm64 2016-12-17T23:38:33Z patrick patrick@openbsd.org 2016-12-17T23:38:33Z urn:sha1:f24071e5a82bde237999ed17cfea827c436463e8 This commit contains all the kernel files related to the OpenBSD/arm64 port. It is based on the PowerPC pmap, loongson, arm/armv7 code and FreeBSD aarch64 code. Hard work done by Dale Rahn.
