[Bug bootstrap/21751] New: [csl-arm-branch] fails to bootstrap with EABI

[bero at arklinux dot org]

Compiling csl-arm-branch with --with-abi=iwmmxt fails in csl_arm_branch as of  
2005/05/25:   
   
gcc/crtstuff.c: In function `__do_global_dtors_aux':  
gcc/crtstuff.c:260: error: `__DTOR_LIST__' undeclared (first use in this  
function)  
gcc/crtstuff.c:260: error: (Each undeclared identifier is reported only once  
gcc/crtstuff.c:260: error: for each function it appears in.)  
make[1]: *** [crtbegin.o] Error 1  
  
 
The problem is that crtstuff.c (__do_global_dtors_aux()) uses __DTOR_LIST__ 
whenever FINI_ARRAY_SECTION_ASM_OP isn't set (which is the case for arm w/ 
EABI), but DTOR_LIST_BEGIN isn't #defined to define __DTOR_LIST__ if 
__ARM_EABI__ is defined (gcc/config/arm/arm.h).

Created an attachment (id=8966)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=8966&action=view)
possible fix

Attaching a patch that makes it compile and (at least to me) looks like it'll
generate the right code.

The patch itself is definitely wrong though (breaks other arches) - it's
probably a matter of adding the right #include somewhere (not familiar with gcc
internals to figure out what exactly should be done).

This is reproducable on HEAD branch as well; it's not limited to  
csl-arm-branch. 
 
The patch I've attached is not sufficient to fix it; the resulting compiler 
sort of works, but produces something like this: 
descriptor_test.o(.text+0xc88): In function `global constructors keyed to 
main': 
descriptor_test.cpp: undefined reference to `__aeabi_atexit' 
/stuff/tmp/cross/lib/gcc/arm-linux/3.4.3/../../../../arm-linux/bin/ld: 
warning: .fini_array section has zero size 
 
when building C++ libraries.

You haven't said how you configured GCC.  I'm guessing you configured for
arm-linux, but with an AAPCS-compatible ABI; you can't do that.  The error isn't
the greatest, but it's hard to guard against all possible misuses of --with options.

The target is arm-none-linux-gnueabi, or arm-none-linuxeabi.

The later error is because your glibc does not include EABI support.  Please see
the libc-alpha list archives for patches, or the source tarballs available from
my company's ARM toolchains for an already-patched version of glibc:

Yes, configuration was  
  
../confiugre --prefix=/usr --target=armv5tel-ark-linux --with-abi=iwmmxt  
--with-arch=iwmmxt --with-cpu=iwmmxt  
  
Trying with -gnueabi now -- but shouldn't --with-abi=iwmmxt imply that 
automatically?

You still won't be able to build it without the glibc patches...

I don't know if it should or not.

GLIBC patches are no longer required and I know folks have built
iwmmxt-targeted ARM Linux toolchains since this was filed.

Is the csl-arm-branch still alive ? Can we clear this one up otherwise?
