# DESTDIR The tree where the module gets installed. [not set]
Eliminate the use of commons in the kernel and modules, simplifying the module linking process and eliminating the risks associated with doubly-defined variables. Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

Introduce a new make variable COMPILER_TYPE that specifies what type of compiler is being used (currently clang or gcc). COMPILER_TYPE is set in the new bsd.compiler.mk file based on the value of the CC variable or, should it prove informative, by running ${CC} --version and examining the output. To avoid negative performance impacts in the default case and correct value for COMPILER_TYPE type is determined and passed in the environment of submake instances while building world. Replace adhoc attempts at determining the compiler type by examining CC or MK_CLANG_IS_CC with checks of COMPILER_TYPE. This eliminates bootstrapping complications when first setting WITH_CLANG_IS_CC.

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>.

The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

Build changes that allow the modules on arm64. - Move the required kernel compiler flags from Makefile.arm64 to kern.mk. - Build arm64 modules as PIC; non-PIC relocations in .o for shared object output cannot be handled. - Do not try to install aarch64 symlink. - A hack for arm64 to avoid ld -r stage. See the comment for the explanation. Some functionality is lost, like ctf handling, but hopefully will be restored after newer linker is available.

Put in a workaround for bug 196407 (arm modules cause crashes & panics). When we started compiling the kernel with -march=armv7 the compiler started emitting new types of relocation info which are incompatible with the shared-lib file format used by .ko modules. This workaround prevents the compiler from emitting the instruction sequences that require the new relocs. This amounts to using an undocumented internal compiler flag, so this is just a temporary workaround while we look for a good fix. PR: 196407

NOFSCHG is still implemented in the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }" to emphasize the fact that NOFSCHG is only supported in a limited fashion and for buildworld.

Do as r289391 did for share/mk and make installing to a non-existent directory an error. Most of these do a 'mkdir -p' or 'install -d' before installing, but add the trailing / here for consistency with the userland install.

Refactor (some more) installation of kernel and module objects. Try to make everyone happy: David (to have debug kernels installed by default), Warner (to be able to override that), and myself (for actually making it all work and to be consistent). Now, if kernel was configured for debugging (through DEBUG=-g in the kernel config file or "config -g"), doing "make install" will install debug versions of kernel and module objects with their canonical names, kernel.debug -> /boot/kernel/kernel if_fxp.ko.debug -> /boot/kernel/if_fxp.ko Installing a kernel not configured for debugging, or debug kernel with INSTALL_NODEBUG variable defined, will install non-debug kernel and module objects. Also, restore the install.debug and reinstall.debug targets that are part of the existing API (they cause some additional gdb(1) scripts to be installed).

Fix the building of null module. In the DIAGNOSTICS case, we include opt_ddb.h. These changes expand green's work of including opt_global.h to prefer opt files in the kernel directory. Further refinement might be needed, but I think this is good. Note: While this is a step on the path to moving the meta information about modules into the config files, it doesn't actually do that. It just pulls in the opt files in a way that allows one to build 'generic' modules outside the tree.

Fix kernel build ${MACHINE} path $M should be the kernel machine src directory, ${MACHINE}. In most cases ${MACHINE} and ${MACHINE_CPUARCH} are the same, but this is not true for pc98 and arm64. It appears we previously set M=${MACHINE_CPUARCH} as a workaround to accommodate pc98, where MACHINE_CPUARCH is pc98 but it uses sys/i386/i386/genassym.c. arm64 relies on this being set correctly, so update $M and add explicit workarounds for pc98.

Remove ilinks in cleandepend directly via CLEANDEPENDFILES. The 'cleanilinks' target is kept since it may still be useful as added in r200178, though never documented. Sponsored by: EMC / Isilon Storage Division

CLEANDEPENDFILES+= ${_ILINKS}
- Remove include links only when .depend is also removed, so that "make depend; make clean; make -n" works. - Preseve kernel's .depend if it already exists and its creation is interrupted. Reported/reviewed by: bde

FAST_DEPEND: Rework how guessed dependencies are handled. Rather than depend on .depend not existing, check the actual .depend.OBJ file that will be used for that object. If it doesn't exist then use the guessed dependencies. FAST_DEPEND may never have a .depend file. Not having one means all of the previous logic would over-depend all object files on all headers which is not what we wanted. It also means that if a .depend is generated before a build is done for _EXTRADEPEND (such as for PROG or LIB) then all of these dependencies would not be used since the .depend wasn't generated from mkdep and the real .depend.* files are not generated until the build.

OBJS_DEPEND_GUESS+= ${SRCS:M*.h}
Add guessed dependencies to OBJS after bsd.dep.mk in case of it adding to SRCS. This was a regression in r295985. bsd.dep.mk adds to SRCS for dtrace probes, yacc grammars and some others. The code that is moving is planned to be removed once FAST_DEPEND is default (and the only option) though since FAST_DEPEND doesn't use this.

.include <bsd.clang-analyze.mk>
Fixed `make depend', which I broke here about a month ago by moving the null default for `depend' from bsd.dep.mk to bsd.obj.mk. bsd.kmod.mk included these files in a bad order, so it picked up the null default.
