Module Name:    src
Committed By:   riastradh

Modified Files:
        src/lib/libm/arch/aarch64: fenv.c
        src/sys/arch/aarch64/aarch64: fpu.c
        src/sys/arch/aarch64/include: armreg.h

Log Message:
When hardware subnormal support is available, disable flush-to-zero.

Similarly, when hardware NaN propagation is available, disable
default-NaN substitution.

This enables IEEE 754 semantics on any hardware that supports it by
default.  Programs that want flush-to-zero or default-NaN substitution
can enable them explicitly.
