Summary 0000067: Confusing error message for invalid -b option arguments
Description $ cparser -bregalloc=foo
error: unknown Firm backend option '-b regalloc=foo'

The phrase "unknown option" is wrong, since -bregalloc is a correct option. However, the option argument is wrong as there is no foo register allocator. Cparser should report a better error message here.

This requires the libFirm API be_parse_arg to be more specific about the error, instead of returning just 0 or 1.

I reformulated the error message in revision e6d78fb8baf911513f0b0a742dff4ba392b81823. Note that I decided to not redesign the firm API as these options are meant for developers only, so I don't think more complicated code is warranted here (you could think of these options as a hack anyway as it is not really the job of libfirm to parse commandline options).
