hi Thomas, Derek, and all,
Pd does actually kill denormals in [send~], [throw~], [line~],
[delwrite~], [hip~], [lop~], [bp~], [biquad~], [tabwrite~], and
[tabsend~]. Some externs do the same, e.g. cyclone's filters and
envelopes.
So, one way to speed things up in a patch would be inserting
a s~/r~ or the like, after finding a proper place for them.
Btw, the PD_BADFLOAT macro seems like the main obstacle in trying
to make Pd conform to gcc-3.3 (other warnings are plain easy to
deal with).
Does anybody know, how to modify it without a performance loss?
