Software FP in RTEMS 4.7 ARM prebuild tools?

[Markku Puro]

Hi Joel,

Is software FP supported in ARM RTEMS 4.7 toolset?

I tried to compile gba BSP with rtems-4.7-arm-rtems4.7-gcc-gcc3.4.0newlib1.12.0-1.i686.rpm
and rtems-4.7-arm-rtems4.7-gcc-gcc3.3.5newlib1.12.0-2.i686.rpm.

------

Older toolsets have separated hardware FP libraries.
Latest tools seems to use hardware FP libraries by default but there isnt any soft-float libs?
