[coldfire-gnu-discuss] insn does not satisfy its constraints

[Maxim Kuvyrkov]

Jeffrey,

Please attach the preprocessed source file so that we can reproduce the problem on our side.  You can get the preprocessed example by adding -save-temps to the command line -- the preprocessed source will be saved in a .i file.

It seems something causes the compiler to generate code that uses a floating point register for a soft-fp target.

Thank you,
