Hi all.
I stumbled across these lines in csc.scm:
[(|-O5|)
(set! rest (cons* "-optimize-level" "5" rest))
(when (memq (build-platform) '(mingw32 cygwin gnu clang))
(set! compile-options
(cons* "-O3" "-fomit-frame-pointer" compile-options)) ) ]
Four arguments against this when-statement:
1. It seems that -O5 does more than -optimize-level 5, which is undocumented
and inconsistent.
2. Furthermore, -fomit-frame-pointer might not help much if the underlying
chicken was built without this option (if I remember correctly).
3. -O3 is often not the best choice for speed, so I would recommend not to
intervene with the settings from the chicken build.
4. Finally, gcc takes the _last_ -O option if several are given, so -O3 has no
effect if "compile-options" contains any -O2 or similar.
In short: Please consider deleting the when-statement ...
Greetings
Sven
