John Sully <j...@csquare.ca> writes: While testing the latest development code we've discovered that it fails on specific Pentium D "Haswell" CPUs. These CPUs are odd in that they don't have the BMI2 instruction set. Because of this GMP will crash when it attempts to execute a MULX. The specific model is: Intel(R) Pentium(R) CPU G3420 From Intel's "ARK" pages and from /proc/cpuinfo it seems that AVX is also missing.
GMP is not prepared for these instruction omissions. The AVX problem should preclude your system from working also with your patch applied. Also, fixing fat builds along is not enough. I am glad you spotted this problem before 5.2!
