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`
