Using more than 15 operands in inline assembly of the symbolic form:
"... lots of assembly elided ..." \
"movaps %[inner_filter_index], %[icoeff_l2]\n\t" \
:[icoeff_l2] "+x" (icoeff_l2), \
[inner_filter_index] "+x" (inner_filter_index), \
... 13 more operands .. .
blows up at 16 register names, which is a bit lower than 30, and in either
case, too low for modern vector architectures such as the x86_64, vmx,
larrabee, etc.
Test program to come...
