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
Speaking from experience, it's heavily used when testing and verifying new processor designs. The instruction set has to be stressed using code that a compiler won't necessarily generate. Rather than writing in some higher level language that may or may not compile to the instructions one wants to check, it's easier to write the assembly by hand.
