To build libio for the C4x, I had to apply the following hack. Is
there a better mechanism that doesn't rely on guessing the modes
corresponding to the data sizes?
Michael.

BTW, modes actually are the most accurate data size indicators we have. Only
the c3x/c4x ports break those assumptions.

Don't forget 1750a and dsp16xx - they have BITS_PER_UNIT as 16.

It would be trivial to patch c-common.c to add additional attributes
that would select the mode with a size greater than or equal to the
desired number of bits.
If this is worthwhile, I'll submit a patch.

Don't forget 1750a and dsp16xx - they have BITS_PER_UNIT as 16.

BTW, modes actually are the most accurate data size indicators we have. Only
