Hi,
The docs (http://wiki.call-cc.org/man/4/Using%20the%20compiler) state
that:
-optimize-level 3 is equivalent to
-optimize-leaf-routines -local -inline -inline-global -unboxing
And that
-unboxing
try to use unboxed temporaries for numerical operations. This
optimization is only effective in unsafe mode.
Since -O3 doesn't use -unsafe and -unboxing is only effective in unsafe
mode, is there any reason for adding -unboxing to level 3?
Best wishes.
Mario
