But be aware that the emulated environment still assumes that all system
calls implemented by 4.15 are available, and qemu linux-user gen

i had a query earlier about libmvec vector functions in fortran:
https://gcc.gnu.org/ml/gcc/2017-11/msg7.html
but there were no simple solutions to make math functions vectorizable
in fortran, because it's hard to make libc headers with simd attributes
visible to the fortran front end.

As I mentioned previously in that thread you linked to, the fortran frontend never generates a direct call to libm sin(), or for that matter

Ouch, there are no reversed interlocked branch instructions in the VAX
ISA, so these would have to branch around
