...list scheduling" and "Force bottom-up list scheduling"
Which isn't too helpful - where might I want to use these? Under what
conditions might they improve an instruction schedule?
Similar questions for the instruction scheduler strategies:
-misched=(default, converge,
ilpmax, ilpmin, or shuffle)
And for the analysis heuristics:
-misched-cluster,
-misched-cyclicpath, -misched-regpressure, and -misched-
fusion
Are these things mutually exclusive or can they be combined? What
combination will give the most rigorous analysis and improve scheduling (at
the cost of longer runtime...

[LLVMdev] [RFC] [ARM] v6m: Suggestions for a slightly different set of default optimizer settings.
...ate bytecode data intermediately. I think
it would help much to expose this feature to the clang level or as part
of the default optimization settings -Os, -O2, -O3.
I observed, that with today's head version, -pre-RA-sched appears to be
hidden from the end user. At a first glance, -misched=ilpmin
-enable-misched -misched-regpressure did give similar results. I would
like to suggest to use them (or a similar configuration) as default for
clang for higher optimization levels. Only if these passes may be
considered to be stable, of course.
As a last point, it would be helpful to empower c...
