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@ Since most (if not all) ARMv8 hardware doesn't actually support trapping of 2018-03-16T10:22:52Z kettenis kettenis@openbsd.org 2018-03-16T10:22:52Z urn:sha1:1ff8d394f3ae9f209c103a45737dbc8f39da325b floating-point exceptions, simplify the functions that control the exception masks just like we did on armv7. ok tom@ Add support for AArch64.
