Thank you for the review and your notice. I was inattentive when
moving changes from the branch I had. This has been fixed in
v2 of the patch [1].
I've manually checked (by objdump -d output review) that now
expected code
From: Pavel Kozlov
Add extra check for compiler definitions to ensure that compiler provides
sqrt and fma hw fpu instructions else use software implementation.
As divide/sqrt and FMA hw support from CPU side is optional,
the compiler can be configured by options to generate hw FPU instructions,
