Last I heard cycling goes fine but FPU options don't get passed down
to other parts of the build process leading to failures if the selected
does not match the default for the OS and variant in question. I imagine you
would have similar problems setting the ABI manually (although I don't
know if there is a trap to catch people who do that or if the compiler will
carry on blindly doing the wrong thing)

There is hardfloat support in freepascal trunk but unless something has
recently I doubt a c style -mfloat-abi will activate it. IIRC the fpc
need for the hardfloat ABI is -CaEABIHF.
For linux you can use -dFPC_ARMHF when building the compiler to select
the armhf "variant" which defaults to armv7-a, vfpv3_d16 and hard float abi.

well it works well enough to build the fpc and lazarus debian packages
(I backported it to 2.6.0 for debian) and I also ran a fairly thourough
of passing parameters to C code to check they were being passed in the
