John, I assume you're doing this for an out of tree port (s12z?)?
That is correct.
Otherwise it'd also be useful if you could include a test which triggers
the assert.
Once I have the other aspects of the port sorted out I can create a test
case (although it wouldn't be necessary because it happens building
libgcc).
If you could confirm that Richard's suggestion of using
GET_MODE_PRECISION rather than GET_MODE_UNIT_PRECISION works it'd be
appreciated.
I had wondered about the difference between the two. Unfortunately,
neither are mentioned in gccint.texinfo - I ended up deciding upon
GET_MOE_UNIT_PRECISION because there is a similar situation a few lines
above in simplify-rtx.c which uses it.
If GET_MODE_UNIT_PRECISION is inappropriate, then please change it.
Regards,
John
