we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.
this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.
i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.
some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h
most of them are most harmless, but the libgcc parts are quite essential.
before this change, all the special rules for .pico files were not applied,
and exception handling wasn't enabled. this caused c++ exceptions not to
work on sparc64.
this fixes the build of boost-headers (it was correctly calling exception
support broken!), which in turn makes all the things that depend upon it
to actually work again on sparc64.
While kernel source code is supposed to use <machine/macros.h> via
<sys/param.h> and pick an inline asm version from there, gcc itself
can generate direct calls to memset() for structure initialization, so
the symbol must be provided.
Fixes INSTALL kernel, for which -Os caused gcc to use memset() call to
initialize a struct in uvm_fault_internal().
that CERROR returns -1 in %a0 in addition to %d0 and %d1, to make functions
like mmap(2), mremap(2), shmat(2) or sbrk(2) return -1 in case of an error.
A side effect of this bug was a segfault caused by jemalloc, when mmap()
failed.
SRCS and add to LSRCS (for lint).
Change the 'string' Makefiles so that the arch/*/string/Makefile.inc
need only specify the .S files for that architecture and not the .c
files for all the files they don't override.
duplicate symbols for index() and rindex().
libc and kernel build ok for affected archs (i386, amd64, vax, sun3,
evbmips-eb) all seem ok.
(vax might lose an asm index() - but comments imply it is worse than the C)
which apparently don't exist as instructions, with a sequence of
std / ld instructions.
Also remove the attempted include of ldstm.S which we don't have.
included in ext_frach, it needs to be masked off when testing for an
infinity value. Fixes the ieeefp/infinity regression test on the 68060
which clears the explicity integer bit when loading an infinity value.
