* config/rs6000/predicates.md (input_operand): Don't match constant pool addresses. Remove label_ref, high and plus from match_code list. Remove redundant CONSTANT_P test. (splat_input_operand): Similarly update match_code list. (small_toc_ref): New predicate. * config/rs6000/rs6000-protos.h (toc_relative_expr_p): Update prototype. * config/rs6000/rs6000.c (tocrel_base, tocrel_offset): Make const. (legitimate_constant_pool_address_p): Move TARGET_TOC test and register checks to.. (toc_relative_expr_p): ..here. Add "strict" param. Match new rtl generated by create_TOC_reference. (rs6000_legitimize_address): Update cerate_TOC_reference call. (rs6000_delegitimize_address): Handle new rtl for toc refs. (rs6000_cannot_force_const_mem, rs6000_find_base_term): Likewise. (use_toc_relative_ref): New function, split out from.. (rs6000_emit_move): ..here. Remove redundant tests. Update create_TOC_reference calls. (rs6000_legitimize_reload_address): Formatting. Handle splitting of medium/large model toc addresses. Use use_toc_relative_ref. (print_operand): Formatting, style. Adjust for toc changes. (print_operand_address): Likewise. (rs6000_output_addr_const_extra): Likewise. (create_TOC_reference): Put TOC_REGISTER in UNSPEC_TOCREL rather than a PLUS. Use this formulation for both high and low part of -mcmodel=medium/large toc reference too. Before reload, always use the small model formulation. * config/rs6000/rs6000.md (tls_gd, tls_gd_high): Similarly avoid a PLUS in high part of addresses here. (tls_ld, tls_ld_high, tls_got_dtprel, tls_got_dtprel_high): Likewise. (tls_got_tprel, tls_got_tprel_high, largetoc_high): Likewise. (largetoc_high, largetoc_low): Move earlier. Cope when no base reg available. (largetoc_high_plus): New insn. (movsi_internal1, movsi_internal1_single, movsf_softfloat, movdi_mfpgpr, movdi_internal64): Don't handle 'R' constraint here.. (tocref): ..instead do so here, new insn and split. From-SVN: r187699 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
