[Bug target/14352] New: New FP code not compiled for non-arm-elf targets

[drow at gcc dot gnu dot org]

Most of the ARM target makefile fragments reference arm/lib1funcs.asm, but only
t-arm-elf references all the symbols that need to be defined to get the new
floating point code:
LIB1ASMFUNCS = _udivsi3 _divsi3 _umodsi3 _modsi3 _dvmd_tls _bb_init_func \
        _call_via_rX _interwork_call_via_rX \
        _negdf2 _addsubdf3 _muldivdf3 _cmpdf2 _unorddf2 _fixdfsi _fixunsdfsi \
        _truncdfsf2 _negsf2 _addsubsf3 _muldivsf3 _cmpsf2 _unordsf2 \
        _fixsfsi _fixunssfsi

t-linux just says this:

LIB1ASMFUNCS = _udivsi3 _divsi3 _umodsi3 _modsi3 _dvmd_lnx

This generates undefined references in libgcc_s.so to, for instance, the functions
defined by L_addsubdf3.

If I copy LIB1ASMFUNCS from t-arm-elf to t-linux that solves the problem (for
this particular target at least, and keeping _dvmd_lnx...)

t-linux is not a soft-float target, so shouldn't need any of the FP 
support functions.

R.

But this prevents using it with -msoft-float; which is often
advantageous.  Hmm, I'm not sure how best to do it, but I'd like to
make this new requirement clearer - especially now that we have
--with-float=soft.

I just ran into this again.  Richard, I know the soft-float routines are not
generally needed, but would there be any harm in building them anyway?

An alternative would be to detect --with-float=soft in t-linux, and adjust
LIB1ASMFUNCS.  I think that can be done.

The none EABI configuration of arm-linux is no longer supported.

This refers to the arm-linux and arm-elf configurations which are largely in
maintenance mode only now. Pulling priority down to P5 and marking as an
enhancement.
