The resulting compiler works on the target but it generates software
floating
point instructions like "bl float64_mul".
Here I get stuck. I cannot get FPC to generate floating point
instructions.
Adding any floating point options to FPC when compiling my
application,
like -CfVFPV3, results in errors like:
PPU Loading /opt/fpc-svn/lib/fpc/2.5.1/units/arm-linux/rtl/system.ppu
Trying to use a unit which was compiled with a different FPU mode
Trying to rebuild my native compiler on the target with -CfVFPV3 in
the
options fails with errors about "selected CPU does not support ARM
mode:....." for all of the floating point instructions generated.
Those errors come from the assembler, not from FPC. You probably have
to add -Cparmv6. See also http://wiki.freepascal.org/FPC_New_Features_Trunk#Support_for_VFPv2_and_VFPv3
