Hello All!
Is it possible to build a softfp uClibc for ARM?
For the records, there are three types of floating point supports on ARM:
ABI | arithmetics | storage
--------+----------------+------------------
hard | instructions | float registers
soft | function calls | integer registers
softfp | instructions | integer registers
Thus, on a CPU with a FPU (VFP, Neon...), softfp takes full advantage of
the FPU, while retaining compatibility with legacy softfloat code (eg. in
a shared library).
True, that's why in embtoolkit I always configure gcc with softfp by default
when hard floating is selected.
So, is it possible to build uClibc using the softfp ABI ?

Last time I tested, it just worked well.
Best regards,
