Subject:         * config/pa/tm-hppa.h (EXTRACT_RETURN_VALUE): Handle software
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=17280c3f6fb315870da0af787abbf22d32578d4b;p=binutils-gdb.git

    * config/pa/tm-hppa.h (EXTRACT_RETURN_VALUE): Handle software
        floating point correctly.
        (STORE_RETURN_VALUE): Likewise.
        * config/pa/tm-pro.h (SOFT_FLOAT): define.
Fixes minor testsuite failures for pro targets.
