#51097: gcc5 -- xgcc internal compiler error: Illegal instruction: 4 -----------------------+------------------------ Reporter: gnwiii@… | Owner: mcalhoun@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: gcc5 | -----------------------+------------------------ Comment (by gnwiii@…): I'm not entirely clear about the "problem". GMP works on the older system when compiled with the "+core2" option or when compiled locally (in which case I assume the configuration stage correctly identifies the processor and applies appropriate algorithms), but the macports binary fails. Since the macports binary did work on the newer iMac, I assume it was built on a system similar to the newer iMac. Are you hoping to create a variant that works for both nehalem and skylake? gcc-mp-5 works for gmpbench using the "patched" library: {{{ $ port installed gmp\* The following ports are currently
