📐 Does calling sqrtf always result in a single asm instruction?
I was recently running some performance benchmarks across different platforms to understand the cost of some simple mathematic functions such as sqrtf and quickly noticed, under certain circumstances compilers such as MSVC, Clang and GCC by default will not generate a single x86-64 sqrtss instruction, there is a little more to it… I think discovering…
