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

# $FreeBSD$
If there is not a CPUTYPE defined by default, then allow for _CPUCFLAGS to tune for more advanced processors while still supporting the minimum processor in an architecture. We can do this with the '-mtune=' option to gcc for alpha, sparc64, and powerpc and with the mis-named '-mcpu=' option for i386. This defaults to tuning i386 builds for i686 machines though not using any instructions that aren't found on an 80386. For alpha it defaults to tuning for an EV5.

TARGET_CPUTYPE should exist solely in Makefile.inc1, similar to TARGET_ARCH and TARGET. This is problematic when one has the = (unconditional) type of assigment for CPUTYPE in /etc/make.conf. (This would override what was set on the command line to "make buildworld".) Add a (horrible) kludge to Makefile.inc1 to check the type of assignment for CPUTYPE (only for those who attempts to set it to a different value). Fix an example make.conf. Fix the kernel's build-tools target (aicasm only at the moment) to catch up with bsd.cpu.mk,v 1.15 (BOOTSTRAPPING replaced with NO_CPU_CFLAGS in Makefile.inc1's BMAKE). Reviewed by: jhb

This are the build infrastructure changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but doesn't abort. They also produce CPU specific code (new instructions of the CPU, not only CPU specific scheduling), so if you get coredumps with signal 4 (SIGILL, illegal instruction) you've used the wrong CPUTYPE.

To use it update share/mk, add /usr/local/intel/compiler70/ia32/bin (icc v7, works) or /usr/local/intel_cc_80/bin (icc v8, doesn't work) to your PATH, make sure you have a new kernel compile directory (e.g. MYKERNEL_icc) and run CFLAGS="-O2 -ip" CC=icc make depend CFLAGS="-O2 -ip" CC=icc make in it. Don't compile with -ipo, the build infrastructure uses ld directly to link the kernel and the modules, but -ipo needs the link step to be performed with Intel's linker. Problems with icc v8: - panic: npx0 cannot be emulated on an SMP system - UP: first start of /bin/sh results in a FP exception Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.

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.

This are the build infrastructure changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but doesn't abort. They also produce CPU specific code (new instructions of the CPU, not only CPU specific scheduling), so if you get coredumps with signal 4 (SIGILL, illegal instruction) you've used the wrong CPUTYPE. Incarnations of this patch survive gcc compiles and my make universe. I use it on my desktop. To use it update share/mk, add /usr/local/intel/compiler70/ia32/bin (icc v7, works) or /usr/local/intel_cc_80/bin (icc v8, doesn't work) to your PATH, make sure you have a new kernel compile directory (e.g. MYKERNEL_icc) and run CFLAGS="-O2 -ip" CC=icc make depend CFLAGS="-O2 -ip" CC=icc make in it. Don't compile with -ipo, the build infrastructure uses ld directly to link the kernel and the modules, but -ipo needs the link step to be performed with Intel's linker. Problems with icc v8: - panic: npx0 cannot be emulated on an SMP system - UP: first start of /bin/sh results in a FP exception Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.
