Subject: rs6000.c (SMALL_DATA_REG): Register to use for small data relocs.
X-Git-Tag: releases/egcs-1.0.0~46
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cfc51775f3e7867f908c349ed3626e6586930fe1;p=thirdparty%2Fgcc.git

rs6000.c (SMALL_DATA_REG): Register to use for small data relocs.

        * rs6000.c (SMALL_DATA_REG): Register to use for small data relocs.
        (print_operand): Use SMALL_DATA_REG for the register involved in
        small data relocations.
        (print_operand_address): Ditto.

        * rs6000/linux.h (LINK_SPEC): Pass -dynamic-linker /lib/ld.so.1 if
        -dynamic linker is not used.

        * rs6000.md (call insns): For local calls, use @local suffix under
        System V.  Don't use @plt under Solaris.
