Will this be the default at build time, or will distros have to set this themselves? +11:54 Could we avoid libgccjit.so? Or consider using another jit lib (e.g. dynasm used by luajit) et al to gain better optimization? +14:22 How much of Emacs's C code base could be translated to emacs-lisp? What is the minimum C code base necessary? +16:23 Could we statically type elisp code (via macros?) to provide more optimization hints to compiler? +17:27 Elisp and Python all are dynamically typed langauge, but benchmark shows that Elisp runs slower than Python.
