I have far more philosophical affection for clang, but great googly moogly,
recent GCC compiles of XEmacs scream. I am compiling with --with-optimization
--without-assertions "CFLAGS=-Ofast -march=native -mfpmath=both
-fomit-frame-pointer -flto", on the same machine I have been using since 2007
(upgraded to an SSD a couple of years ago, am otherwise perfectly happy with
the original hardware + maxed-out RAM), and there’s a dramatic responsiveness
to the GUI stuff that wasn’t there certainly four or five years ago.
On one level this means it’s a good thing that so much of XEmacs is still in
C, no-one else is putting this much effort into any Emacs Lisp compiler.
On another level, it is a shame we didn’t move towards full-on Common Lisp
back in the late 90s. Say, if we had the SBCL compiler at our disposal for the
dumped code, and byte-compiled the packages in the old way for the sake of GNU
compatibility for them. Ah well.
