Is inline assembly language slower than native C++ code?
...ion scheduling, for example, is very hard to tune by hand) and modern CISC CPUs have very long pipelines too.
For some complex microcontrollers even system libraries are written in C instead of assembly because their compilers produce a better (and easy to maintain) final code.
