Android engineers at Google added support for the Java and Kotlin programming languages to Compiler Explorer, an open source tool aimed at exploring how compilers work by compiling code in real ...

Today’s optimizing compilers output machine code so compact and efficient that only a master assembly language programmer could compete. Further optimization by hand simply isn’t worth the effort.

As DSP processors become more and more powerful, the portion of code that can remain at the C level increases. However, compilers cannot produce optimized code without assistance from the programmer.
