#51097: gcc5 -- xgcc internal compiler error: Illegal instruction: 4 -----------------------+------------------- Reporter: gnwiii@… | Owner: mww@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: gcc5 | -----------------------+------------------- Comment (by mcalhoun@…): GMP has a script {{{config.guess}}} that prints "the host system CPU- VENDOR-OS."[[BR]] The CPU value is used to set {{{-mtune}}}, set {{{-march}}}, and select assembly files to use.[[BR]] The {{{+core2}}} variant forces the CPU value to be core2.[[BR]] With a little trial and error, we can probably narrow down the problem.[[BR]] Since I can not reproduce this problem, I will need a little help. 1. Does {{{port test gmp}}} report any errors? 2. What is the output of {{{config.guess }}} (located in the GMP source directory)? With this information, we can modify the CPU specific code in {{{configure}}} that is different from (the working) core2 code. -- Ticket URL: <https://trac.macports.org/ticket/51097#comment:7> MacPorts <https://www.macports.org/> Ports system for OS X
