Subject: sh.c (dump_table): handle SFmode and DFmode.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e577c183dd7e2cb4d14a79abba53353534f5f74d;p=gcc.git

sh.c (dump_table): handle SFmode and DFmode.

        * sh.c (dump_table): handle SFmode and DFmode.
        (broken_move): handle simple PARALLEL.
        (machine_dependent_reorg, pc-relative move generation): Likewise.
