What kind of projects (besides the obvious OS stuff) use assembly language?

Question

Seemingly, no one uses assembly nowadays other than to develop device drivers, or the very core of OS kernels etc. Anyone has knowledge of it being currently used for other thin

Answer 1

Sometimes certain features are not implementable in a high level language, and inline assembly is used instead. There is some inline assembly in the C++ library Qt, for example; I believe it's used for part of the object introspection system.

In addition, glibc (the C library for gcc) uses assembly for optimization. IIRC one of the software-based floating-point math implementations has significant chunks written in assembly.

One of the primary reasons for learning assembly, however, is debugging. On a few occasions, I've gotten myself into situations where not knowing assembly would have prevented me from debugging a particularly sticky problem.
