Summary

0000888: FLOAT: Toolchain build fails on non-FPU ARM

Description

t-linux and t-linux-uclibc are missing the new hand-coded FP functions of newer GCCs. This triggers a link failure due to unresolved symbols during uClibc compilation.

Additional Information

A quich fix: in gcc-4.x.x/gcc/config/arm/t-linux:

LIB1ASMSRC = arm/lib1funcs.asm
LIB1ASMFUNCS = _udivsi3 _divsi3 _umodsi3 _modsi3 _dvmd_lnx _bb_init_func \
        _call_via_rX _interwork_call_via_rX \
        _lshrdi3 _ashrdi3 _ashldi3 \
        _negdf2 _addsubdf3 _muldivdf3 _cmpdf2 _unorddf2 _fixdfsi _fixunsdfsi \
        _truncdfsf2 _negsf2 _addsubsf3 _muldivsf3 _cmpsf2 _unordsf2 \
        _fixsfsi _fixunssfsi _floatdidf _floatdisf
