The RISC-V port contains a crti.S that simply contains a link to PREINIT_FUNCTION (when defined). As this should be entirely generic, Joseph Myers suggested that we update the generic init_array version to contain this. Since RISC-V is the only user of init_array this won't break any existing ports. 2018-01-26 Palmer Dabbelt <palmer@sifive.com> * sysdeps/init_array/crti.S (.section .init_array): Add PREINIT_FUNCTION when defined. --- sysdeps/init_array/crti.S | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
