i have cross build with ppc and qemu partly working
but it appears gcc or something is just buggy
for example this:
#include <math.h>
main() {
float f = 0.0/0.0;
printf("%f\n", floor(f));
}
produces:
510423550381407695195061911147652317184.000000
but if build with -O1 it produces this:
nan
thats with powerpc-linux-gnu-gcc-4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4
also
gcc -O1 behaves different from litterally listing all the options that -O1
is documented to turn on
the remaining issues are:
make: *** [fate-eval] Error 1
make: *** [fate-filter-tremolo] Error 1
make: *** [fate-filter-refcmp-psnr-rgb] Error 1
make: *** [fate-parseutils] Error 1
where eval and parseutils appear to be issues with non finite numbers
not sure iam missing something ...
