Subject: config.gcc (sparcv9-solaris): Configure for 64-bit default.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8947df0cbb2076cfb4bee2b628892d1249da723b;p=gcc.git

config.gcc (sparcv9-solaris): Configure for 64-bit default.

        * config.gcc (sparcv9-solaris): Configure for 64-bit default.
        Adjust tm_file order to get TARGET_DEFAULT set properly.
        (sparc-solaris): Configure 2.[78] for 64-bit multilibs.
        * doc/install.texi (sparc-solaris): Update.
