Instead of compiling files with -fcommon, create an include file and declare
the 3 symbols that need to be common using an attribute. Put all the 3 symbol
definitions in libc in one place (initfini.c). Reviewed by joerg@

Explicitly use -fcommon for globals shared between libc and CSU.

Oops, revert previous; thinko.

Go ahead and built c++rt0.o on all non-ELF platforms (i.e. including arm32;
the hacks to make this work have been committed).

Don't build c++rt.o if ELF.

This needs to use C///, not S///.

Clean up mipse[bl]->mips substitution.

make this build again after the mips->mipse? transition

If object_fmt == elf and we have machine_elf, build that one.

Do not build on arm32 by default.
This is temporary.

GC alpha's ECOFF_TOOLCHAIN make variable, and related bits. Nobody
should be using an ECOFF toolchain on NetBSD/alpha any more.

NetBSD/powerpc doesn't use the "generic" c++rt0.o

Someone forgot a line continuation character

turn Alpha's ELF_TOOLCHAIN checks to ECOFF_TOOLCHAIN checks

RCS id police.

add a hack so that old- and new-toolchain alphas do the right thing:
include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN,
build c++rt0.o. ELF alphas don't use the 'normal' C++ runtime startup
routines. Eventually, there should be better ways to distinguish what
toolchain and object format is in use, and the Alpha C++ startup code
changes should be merged with that used by the other ports.

c++ not g++

Subdirectory g++ contains C++ shared library helper routines.

use MACHINE_ARCH to pick which crt0 to use.

Revert -O1 hack for GCC 5.3, replaced by workaround in the code.

We need the -O1 hack (for gcc 5.3) for crtbegin.c as well.
Works around PR toolchain/51121.

Revert previous (fallout is more subtle but there).
Rework the conditionon so it depends on .S existence instead of an arch
list.

Gcc 5.3 seems to do fine compiling this for sparc64, so exclude it
from the -O1 hack

For the benefit of compilers not using our native C runtime environment,
install a "sysident.o" file providing the note identifying NetBSD
executables (and marking the currently installed version).

crt0-common.c is miscompiled by gcc 5.3 on evbarm with -O2 so use -O1. Do
this for all non-x86 arches.

add a hack for GCC 5 and non-x86 platforms:

build crtbeginS.o with -O1 as GCC tries to be very smart with the
__DTOR_LIST__ as it believes it knows the size of the array at
compile time (which is not true until link time). on SPARC and
MIPS, the result was emitting a call to 0.

technically, i believe that GCC isn't "wrong" to make this choice,
as the array is declared with a well-known initialiser size in the
crtbegin.c compilation unit, and we have noticed that the libgcc
version of this code has some hacks added, most likely to avoid
being bitten by this optimisation.


this makes sshd work for me on earm and sparc with GCC 5.

Add GENASSYM_CPPFLAGS in two more places.

Using ${LD} -x screws up BE arm. Use ${OBJCOPY} ${OBJCOPYLIBFLAGS} instead

PR toolchain/51121:
__CTOR_LIST__ and __CTOR_LIST_END__ are logically the same object, but
due to the start marker, the former has to be declared as array of fixed

accessing global objects past the end to unconditionally load zero
values in that case. Two fixes are possible:
(1) Pruning via inline assembler as done by GCC's own CRT copy.
(2) Pruning via weak references as done for linker sets.

approach. In theory, the labels could be replaced completely, except

Ensure notes are properly padded to 32bit length.

branches: 1.2.2;
Add support for a NetBSD MARCH elf note to record the MACHINE_ARCH for
which a program was compiled.

branches: 1.1.6; 1.1.12;
Switch i386 and x86_64 to the new CRT layout. The crt0.c body is shared
between all platforms and a small assembler stub in crt0.S is used for
setting up the proper stack and whatever else MD needs.

Extract crti.S and crtn. from the old dot_init.h files. Prepare other
platforms that use the 6-argument form of __(_)start for this.

Rewrite the crtbegin and crtend modules in assembler to make them
compiler independent. Document the interface in README.

On sparc64: create additional "marker" object files, that can be used by the
compiler to encode the used code model in binaries.
