Upgrading build system to new NetBSD revision The tested targets are the followgin ones: * tools * distribution * sets * release The remaining NetBSD targets have not been disabled nor tested at all. Try them at your own risk, they may reboot the earth. For all compliant Makefiles, objects and generated files are put in MAKEOBJDIR, which means you can now keep objects between two branch switching. Same for DESTDIR, please refer to build.sh options. Regarding new or modifications of Makefiles a few things: * Read share/mk/bsd.README * If you add a subdirectory, add a Makefile in it, and have it called by the parent through the SUBDIR variable. * Do not add arbitrary inclusion which crosses to another branch of the hierarchy; If you can't do without it, put a comment on why. If possible, do not use inclusion at all. * Use as much as possible the infrastructure, it is here to make life easier, do not fight it. Sets and package are now used to track files. We have one set called "minix", composed of one package called "minix-sys" 2012-09-12 09:37:05 +02:00			`# LSC For now`

Move elf headers in common/include and libexec.h in lib/libexec. It also fixes elf headers for NBSD compilation. 2011-03-18 16:13:05 +01:00			`INCS= libexec.h`
exec() cleanup, generalization, improvement . make exec() callers (i.e. vfs and rs) determine the memory layout by explicitly reserving regions using mmap() calls on behalf of the exec()ing process, i.e. handling all of the exec logic, thereby eliminating all special exec() knowledge from VM. . the new procedure is: clear the exec()ing process first, then call third-party mmap()s to reserve memory, then copy the executable file section contents in, all using callbacks tailored to the caller's way of starting an executable . i.e. no more explicit EXEC_NEWMEM-style calls in PM or VM as with rigid 2-section arguments . this naturally allows generalizing exec() by simply loading all ELF sections . drop/merge of lots of duplicate exec() code into libexec . not copying the code sections to vfs and into the executable again is a measurable performance improvement (about 3.3% faster for 'make' in src/servers/) 2012-05-30 19:34:07 +02:00			`SRCS= exec_aout.c exec_elf.c exec_general.c`

Reduce compiler/libraries/headers cases to only two 1. ack, a.out, minix headers (moved to /usr/include.ack), minix libc 2. gcc/clang, elf, netbsd headers (moved to /usr/include), netbsd libc (moved to /usr/lib) So this obsoletes the /usr/netbsd hierarchy. No special invocation for netbsd libc necessary - it's always used for gcc/clang. 2011-07-01 15:57:43 +02:00			`.else`
