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. (xcoff_howto_table): Remove src_mask for TOC relocations. Add R_TOCU and R_TOCL howtos. (_bfd_xcoff_reloc_type_lookup): Add cases for BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO. (xcoff_reloc_type_toc): Compute the whole offset. Implement R_TOCU and R_TOCL. * coff64-rs6000.c (xcoff64_calculate_relocation): Likewise. (xcoff64_howto_table): Likewise.

(ppc_tc): Enable .tc symbols to have only a XMC_TC or XMC_TE storage class. (ppc_symbol_new_hook): Handle XMC_TE. (ppc_frob_symbol): Likewise. (ppc_fix_adjustable): Likewise. (md_apply_fix): Handle BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO. ld/ * scripttempl/aix.sc: Add .te to .data section. * testsuite/ld-powerpc/aix52.exp: Add test structure for AIX7+. Add aix-largetoc-1 test. * testsuite/ld-powerpc/aix-largetoc-1-32.d: New test. * testsuite/ld-powerpc/aix-largetoc-1-64.d: New test. * testsuite/ld-powerpc/aix-largetoc-1.ex: New test. * testsuite/ld-powerpc/aix-largetoc-1.s: New test. |
