Overhaul the MACHINE_CPU behaviour: * Rip out MACHINE_CPU stuff from sys.mk and include a new <bsd.cpu.mk> after we pull in /etc/make.conf. We need to do it afterwards so we can react to the user setting of the: * CPUTYPE variable, which contains the CPU type which the user wants to optimize for. For example, if you want your binaries to only run on an i686-class machine (or higher), set this to i686. If you want to support running binaries on a variety of CPU generations, set this to the lowest common denominator. Supported values are listed in make.conf. * bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the (hopefully) correct unordered list of CPU types which should be used on that CPU. For example, an AMD k6 CPU wants any of the following: k6 k5 i586 i486 i386 This is still an unordered list so the client makefile logic is simple - client makefiles need to test for the various elements of the set in decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before. The various MACHINE_CPU lists are believed to be correct, but should be checked. * If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc). Release builders and developers of third-party software need to make sure not to enable CPU-specific optimization when generating code intended to be portable. We probably need to move to an /etc/world.conf to allow the optimization stuff to be applied separately to world/kernel and external compilations, but it's not any worse a problem than it was before. * Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE. * Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc (only i386, alpha and ia64 first, since those are the minimally-working ports. Other architecture porters, please feel free to add the relevant gunk for your platform). Reviewed by: jhb, obrien

We need to do it afterwards so we can react to the user setting of the: * CPUTYPE variable, which contains the CPU type which the user wants to optimize for. For example, if you want your binaries to only run on an i686-class machine (or higher), set this to i686. If you want to support running binaries on a variety of CPU generations, set this to the lowest common denominator. Supported values are listed in make.conf. * bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the (hopefully) correct unordered list of CPU types which should be used on that CPU. For example, an AMD k6 CPU wants any of the following: k6 k5 i586 i486 i386 This is still an unordered list so the client makefile logic is simple - client makefiles need to test for the various elements of the set in decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before. The various MACHINE_CPU lists are believed to be correct, but should be checked. * If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc). Release builders and developers of third-party software need to make sure not to enable CPU-specific optimization when generating code intended to be portable. We probably need to move to an /etc/world.conf to allow the optimization stuff to be applied separately to world/kernel and external compilations, but it's not any worse a problem than it was before. * Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE. * Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc (only i386, alpha and ia64 first, since those are the minimally-working ports.
