* elf32-tic6x.c (elf32_tic6x_final_link): New function. (elf32_tic6x_merge_attributes): Do not warn for PID or PIC mismatch. Choose the lower of the two values. (bfd_elf32_bfd_final_link): New macro. ld/testsuite/ * ld-tic6x/shared-nopic.d: New test. * ld-tic6x/shared-nopid.d: New test. * ld-tic6x/attr-pid-21.d: Don't expect a warning; check readelf output instead. * ld-tic6x/attr-pid-12.d: Likewise. * ld-tic6x/attr-pic-01.d: Likewise. * ld-tic6x/attr-pic-10.d: Likewise. * ld-tic6x/attr-pid-01.d: Likewise. * ld-tic6x/attr-pid-10.d: Likewise. * ld-tic6x/attr-pid-02.d: Likewise. * ld-tic6x/attr-pid-20.d: Likewise. * ld-tic6x/got-reloc-inrange.d: Pass -mpic and -mpid options to gas.
