Hello,
I was able to build package gmp-ecm_6.4.4+ds-2 with patch that is attached.
First part of patch is taken from upstream (file longlong.h)
I had to add second part (file sp.h) in order to build package successfully.
Patch is attached.
Alternatively, if following code for umul_ppm is used, instead of upstream
patch,
package also does build successfully.
#define umul_ppmm(w1, w0, u, v) \
__asm__ ("multu %2,%3\n\tmflo %0\n\tmfhi %1" \
: "=d" (w0), "=d" (w1) : "d" (u), "d" (v))
Thank you!
Regards,
Jurica
