I'm at git 682bf11188e5486610c284900943c5519b2acd87.
With this simple test code:
import("music.lib");
gain = hslider("gain",0,0,1,0.1) : bsmooth;
process = *(gain);
'faust test.dsp' gives a compute function like this:
virtual void compute (int count, FAUSTFLOAT** input, FAUSTFLOAT** output) {
int iSlow0 = min(4096, max(1, count));
float fSlow1 = (1.0f / float(iSlow0));
float fSlow2 = float(fslider0);
int iSlow3 = int(iSlow0);
FAUSTFLOAT* input0 = input[0];
FAUSTFLOAT* output0 = output[0];
for (int i=0; i<count; i++) {
fVec0[IOTA&8191] = fSlow2;
fRec0[0] = (fRec0[1] + (fSlow1 * (fSlow2 - fVec0[(IOTA-iSlow3)&8191])));
output0[i] = (FAUSTFLOAT)((float)input0[i] * fRec0[0]);
// post processing
fRec0[1] = fRec0[0];
IOTA = IOTA+1;
}
}
while 'faust -vec test.dsp' gives the following, see my comment on the
third line:
virtual void compute (int fullcount, FAUSTFLOAT** input, FAUSTFLOAT** output) {
float fRec0_tmp[32+4];
int iSlow0 = min(4096, max(1, count)); /// <--- count is not an
existing variable here
float fSlow1 = (1.0f / float(iSlow0));
float fSlow2 = float(fslider0);
int iSlow3 = int(iSlow0);
float* fRec0 = &fRec0_tmp[4];
int index;
for (index = 0; index <= fullcount - 32; index += 32) {
// compute by blocks of 32 samples
const int count = 32;
FAUSTFLOAT* input0 = &input[0][index];
FAUSTFLOAT* output0 = &output[0][index];
// SECTION : 1
// LOOP 0x7ffdb347e880
// pre processing
fVec0_idx = (fVec0_idx+fVec0_idx_save)&8191;
// exec code
for (int i=0; i<count; i++) {
fVec0[(fVec0_idx+i)&8191] = fSlow2;
}
// post processing
fVec0_idx_save = count;
// SECTION : 2
// LOOP 0x7ffdb347ddf0
// pre processing
for (int i=0; i<4; i++) fRec0_tmp[i]=fRec0_perm[i];
// exec code
for (int i=0; i<count; i++) {
fRec0[i] = (fRec0[i-1] + (fSlow1 * (fSlow2 -
fVec0[(fVec0_idx+i-iSlow3)&8191])));
}
// post processing
for (int i=0; i<4; i++) fRec0_perm[i]=fRec0_tmp[count+i];
// SECTION : 3
// LOOP 0x7ffdb347dd10
// exec code
for (int i=0; i<count; i++) {
output0[i] = (FAUSTFLOAT)((float)input0[i] * fRec0[i]);
}
}
if (index < fullcount) {
// compute the remaining samples if any
int count = fullcount-index;
FAUSTFLOAT* input0 = &input[0][index];
FAUSTFLOAT* output0 = &output[0][index];
// SECTION : 1
// LOOP 0x7ffdb347e880
// pre processing
fVec0_idx = (fVec0_idx+fVec0_idx_save)&8191;
// exec code
for (int i=0; i<count; i++) {
fVec0[(fVec0_idx+i)&8191] = fSlow2;
}
// post processing
fVec0_idx_save = count;
// SECTION : 2
// LOOP 0x7ffdb347ddf0
// pre processing
for (int i=0; i<4; i++) fRec0_tmp[i]=fRec0_perm[i];
// exec code
for (int i=0; i<count; i++) {
fRec0[i] = (fRec0[i-1] + (fSlow1 * (fSlow2 -
fVec0[(fVec0_idx+i-iSlow3)&8191])));
}
// post processing
for (int i=0; i<4; i++) fRec0_perm[i]=fRec0_tmp[count+i];
// SECTION : 3
// LOOP 0x7ffdb347dd10
// exec code
for (int i=0; i<count; i++) {
output0[i] = (FAUSTFLOAT)((float)input0[i] * fRec0[i]);
}
}
