Steve,
OK. I put your denormal-zeroing function w/SSE into the freeverb.cpp
code, and when compiling with the SSE option and calling
set_denormal_flags() in the activateFreeverb3 function (see below), I
get this error wherever asm is called:
freeverb/freeverb.cpp: In function `void set_denorma
Hi,
I compiled the CMT plugins with the g++ options -msse2 and -march=i686
and the freeverb denormals problem (seen with ardour on a dual Xeon
machine) seems to be _almost_ entirely fixed. Also, I don't see any
weird problems with the ardour host (yet :). But, I still see the DSP
load increa

I'm not too sure, but I'd know if I saw it :-).

That looks OK to me, and the optimiser should not discard it because s
is volatile. Have you looked at the assembler output?
I used this new function and set all
