* module/language/cps/effects-analysis.scm: Rewrite so that instead of the depends/causes effects, there is just &type-check, &allocation, &read, and &write. The object kind is a separate part of the bitfield, and the field in the object (if appropriate) is another field. Effects are still a fixnum. This enables precise effects for vectors and structs on all architectures. This kind of effects analysis was not possible in Tree-IL because Tree-IL relied on logior-ing effects of subexpressions, whereas with CPS we have no sub-expressions and we do flow analysis instead. (effect-clobbers?): Replace effects-commute? with this inherently directional and precise predicate. * module/language/cps/cse.scm (compute-always-available-expressions): (compute-equivalent-subexpressions): Adapt to effects analysis change. * module/language/cps/dce.scm (compute-live-code): Likewise. |
