BTW, there's much more assembly code in OpenJDK than you'd find by looking for assembly files. There's a lot of code (all of the interpreter, for example) that's generated at startup time, and written in assmebly as a C++ DSL. E.g. https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/x86/templateTable_x86.cpp https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/x... and https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/x86/templateInterpreterGenerator_x86.cpp https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/x...
