Pick up sfront 0.47 11/21/99 at:
http://www.cs.berkeley.edu/~lazzaro/sa/
From the change log:
Version 0.47 -- 11/21/99
[1] Fixes optimizer bugs, and
adds new optimizations. New
optimizations focus on effects
instruments, and specializes
generated code to the unique
properties of instruments
launched using send().
----The major update in this revision involves specializing the code generation for effects instruments (launched via the send command) to eliminate a level of indirection in accessing memory. Typical performance improvement on an effects-heavy examples/beat/beat.saol:
using sfront 0.46:
/usr/bin/time -p ./sa real 7.62 user 7.46 sys 0.11
using sfront 0.47
/usr/bin/time -p ./sa real 6.92 user 6.65 sys 0.22
About an 11% improvement in user time.
Bug fixes in this release involve fixing exports and call-by-reference bugs introduced by the constant optimization.
