dvec4, lvec4 and ulvec4 need to be aligned to 8 words (32 bytes) in order to avoid hardware exceptions. Rather than dealing with possibly mixed alignment when a function has 8-word aligned locals but only 4-word aligned parameters, simply keep the stack frame 8-word aligned at all times. As for sizes, the temp def recycler was written before the Ruamoko ISA was even a pipe dream and thus never expected temp def sizes over 4. At least now any future adjustments can be done in one place. My quick and dirty test program works :) dvec4 xy = {1d, 2d, 0d, 0.5}; void printf(string fmt, ...) = #0; int main() { dvec4 u = {3, 4, 3.14}; dvec4 v = {3, 4, 0, 1}; dvec4 w = v * xy + u; printf ("[%g, %g, %g, %g]\n", w[0], w[1], w[2], w[3]); return 0; } |
