GSoC 2019 | POSIX Compliance - Need further guidance on fenv sources.

[Vaibhav Gupta]

Hello,
I have found sources for fenv.

It's impossible to depend on either NetBSD or FreeBSD.
.
For some architectures, FreeBSD has code,
for some, NetBSD has.
.
For x86, Free BSD has explicit header
and NetBSD has .c file.
.
.
So should I leave architectures which are not having FreeBSD Source?
Or should I go for particular source for a specific architecture?

1.1) - ARM FreeBSD Source:
- https://github.com/freebsd/freebsd/blob/master/lib/msun/arm/fenv.h
- https://github.com/freebsd/freebsd/blob/master/lib/msun/arm/fenv.c
.
1.2) - ARM NetBSD Source :
