Subject: Add open coding for bit-wise boolean operations, and
X-Git-Tag: 20090517-FFI~11352
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=bead59c0c004f48f128db16d9551b04389d2a1e3;p=mit-scheme.git

Add open coding for bit-wise boolean operations, and
primitive-object-ref/set! .

Enable the open coding of fixnum-quotient and fixnum-remainder.

Add optimizations for these operations when the second operand is a
power of 2 (tricky, see GLS's paper "Arithmetic shifting considered
harmful").
