Implement support for largetoc on XCOFF. R_TOCU and R_TOCL are referenced by the new BFD defines: BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO. A new toc storage class is added XMC_TE. In order to correctly handle R_TOCU, the logic behind xcoff_reloc_type_toc is changed to compute the whole TOC offset instead of just the difference between the "link" offset and the "assembly" offset. In gas, add a function to transform addis format used by AIX "addis RT, D(RA)" into the ELF format "addis RT, RA, SI". bfd/ * reloc.c (BFD_RELOC_PPC_TOC16_HI, BFD_RELOC_PPC_TOC16_LO): New relocations. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * coff-rs6000.c (xcoff_calculate_relocation): Call xcoff_reloc_type_toc for R_TOCU and R_TOCL.
