------=_Part_6201_15382802.1188284098363 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline Gcc 4.2 has a new cpu_type (native) for x86 and amd64 systems. This cpu_type is to allow gcc to automatically detect the processor type that gcc is running on. The problem is that setting CPUTYPE?=native in either src.conf or make.conf will cause MACHINE_CPU to be set to the wrong value for the native cpu. For example on a system where the processor is a k8, setting CPUTYPE to k8, shows that MACHINE_CPU is set as follows: hp010# make -V MACHINE_CPU -DCPUTYPE=k8 k8 3dnow amd64 sse2 sse mmx But setting CPUTYPE to native on a k8 system sets MACHINE_CPU to this value: hp010# make -V MACHINE_CPU -DCPUTYPE=native unknown amd64 sse2 sse mmx After patching share/mk/bsd.cpu.mk (see attachment) or the last patch to PR 112997: http://www.freebsd.org/cgi/query-pr.cgi?pr=112997 setting CPUTYPE to native now works correctly when setting the value for MACHINE_CPU: hp010# make -V MACHINE_CPU -V CPUTYPE -DCPUTYPE=native k8 3dnow amd64 sse2 sse mmx k8 Could this get committed before -CURRENT is branched.
