libgcc:
* config/cris/arit.c (DS): Apply attribute __fallthrough__.
Without this, there are, for each compilation of arit.c, 30ish
occurrences of "this statement may fall through
[-Wimplicit-fallthrough=]", for lines that look like
case 32: DS; case 31: DS; case 30: DS; case 29: DS;
Noticed while working on the cc0 transition. Looks like I don't
inspect the logs often.
Adding -Werror to libgcc build-options should perhaps be
considered?
