+
+ * configure.in (mips-*-irix5*): New target. Use elf and mips-big.
+ * config/obj-elf.c: If ECOFF_DEBUGGING, include ecoff.h.
+ (obj_pseudo_table): If ECOFF_DEBUGGING, define ECOFF
+ pseudo-ops.
+ (obj_read_begin_hook): If ECOFF_DEBUGGING, call
+ ecoff_read_begin_hook.
+ (obj_symbol_new_hook): If ECOFF_DEBUGGING, call
+ ecoff_symbol_new_hook.
+ (obj_elf_init_stab_section): Cast alloca result.
+ (elf_frob_file): If ECOFF_DEBUGGING, finish up ECOFF debugging
+ information and write it out into .mdebug section.
+ * config/obj-elf.h (ELF_TARGET_SYMBOL_FIELDS): New macro.
+ (TARGET_SYMBOL_FIELDS): Use ELF_TARGET_SYMBOL_FIELDS.
+ (ECOFF_DEBUGGING): Define if TC_MIPS.
+ (TARGET_SYMBOL_FIELDS): If ECOFF_DEBUGGING, override to add
+ fields required by ECOFF.
+ * config/tc-mips.c: Check ECOFF_DEBUGGING rather than
+ OBJ_ECOFF in many cases.
+ (mips_any_noreorder): New variable.
+ (mips_cprestore_offset): Initialize to -1.
+ (mips_frame_reg): New variable.
+ (RELAX_ENCODE, RELAX_OLD, RELAX_NEW, RELAX_RELOC1,
+ RELAX_RELOC2, RELAX_RELOC3, RELAX_WARN): New macros.
+ (md_pseudo_table): Handle "gpword" and "cpadd".
+ (md_begin): Initialize ok to false. If OBJ_ELF, set alignment
+ of text, data and bss sections to 4. Set alignment of
+ .reginfo section to 2. If ECOFF_DEBUGGING, create .mdebug
+ section.
+ (ALIGN_ERR, ALIGN_ERR2): Removed unused and useless alignment
+ check.
+ (append_insn, macro_build, macro_build_lui): Take place
+ argument. Changed all callers.
+ (append_insn): If appending a nop, don't emit one.
+ (macro_build): Changed assertion for 'i', 'j', 'o' case.
+ (gp_reference): Removed.
+ (load_address): New function.
+ (macro): If mips_noreorder is used, set mips_any_noreorder.
+ Extensive changes to handle GP and PIC symbols differently.
+ Build both possible code choices using a variant frag, and
+ make a final decision at the end of assembly when all
+ information is known. Added PIC support for all symbol
+ references.
+ (mips_ip): Don't permit anything but a number after $ for a
+ coprocessor register. Don't use .lit4 or .lit8 sections when
+ generating PIC code. If OBJ_ELF, set alignment of .lit4 or
+ .lit8 section to 4.
+ (md_apply_fix): Accept and ignore GOT16 and GPREL32 relocs.
+ (s_change_sec): Set alignment of ELF .rodata or .sdata section
+ to 4.
+ (s_mipsset): If .set noreorder, set mips_any_noreorder.
+ (s_cpload): Ignore .cpload if not generating PIC code. Warn
+ if .cpload is not in noreorder section.
+ (s_cprestore): Ignore .cprestore if not generating PIC code.
+ (s_gpword, s_cpadd): New functions.
+ (tc_get_register): Added frame argument; if true, set
+ mips_frame_reg to return value. Changed all callers.
+ (md_estimate_size_before_relax): Don't error out, but instead
+ determine how much a frag should grow.
+ (tc_gen_reloc): Return multiple relocs if appropriate, as
+ determined by md_estimate_size_before_relax.
+ (md_convert_frag): New function.
+ (mips_elf_final_processing): Set ELF header flags based on
+ mips_any_noreorder and mips_pic.
+ * config/tc-mips.h (RELOC_EXPANSION_POSSIBLE): Define.
+ (MAX_RELOC_EXPANSION): Define to be 3.
+ (md_relax_frag): Define to be 0.
+ (md_convert_frag): Don't define.
+ (tc_get_register): Changed declaration.
+
+ * ecoff.h, ecoff.c: New files pulled out of config/obj-ecoff.c to
+ support generating ECOFF debugging information for MIPS ELF
+ targets. Compiled only if ECOFF_DEBUGGING is defined. Changed
+ handling of external symbols: it now always generates exactly
+ those external symbols that are defined in the global symbol list.
+ * Makefile.in (REAL_SOURCES): Added ecoff.c.
+ (REAL_HEADERS): Added ecoff.h.
+ (OBJS): Added ecoff.o.
+ (ecoff.o): New target.
+ * config/obj-ecoff.c: Almost entirely moved into ecoff.c.
+ Remaining code mostly just calls ecoff.c code.
+ * config/obj-ecoff.h: Define ECOFF_DEBUGGING.
+ (TARGET_SYMBOL_FIELDS): Make ecoff_symbol a pointer to a
+ struct localsym.
+ (obj_read_begin_hook, obj_symbol_new_hook): Define to call
+ functions in ecoff.c.
+ (ecoff_stab): Don't declare (now declared in ecoff.h).
+ (obj_set_sym_index): Define.
+ (obj_ecoff_set_sym_index): Declare.
+
+ * frags.h (frag_grow): Declare.
+ * frags.c (frag_grow): Made non-static.
+
+ * write.c (is_dnrange): Do not define if md_relax_frag is defined.
+ (relax_segment): If md_relax_frag is defined, use it to handle a
+ frag of type rs_machine_dependent rather than looking through
+ md_relax_table.
+
+ * read.c (read_a_source_file): If we find a bad pseudo-op,
+ do a continue to go on to the next line rather than a break.
+ Removed duplicate bad pseudo-op code which was never executed.
+
+ * read.c (s_lcomm): Do not require a comma after the name.
+
+ * subsegs.h (segment_info_type): Changed hadone field to bitfield.
+ Added bss bitfield.
+ * as.c (perform_an_assembly_pass): Set bss flag for bss_section.
+ * read.c (s_lcomm): Set bss flag for .sbss section if used.
+ * write.c (relax_and_size_seg): Don't set SEC_HAS_CONTENTS for a
+ bss section. Set SEC_RELOC if there are any relocations, even for
+ a zero size section.
+
+ * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, base
+ data offset on reloc[0]->address rather than reloc[j]->address, so
+ that multiple relocs can affect different memory locations.
+
+ * write.c (chain_frchains_together, relax_and_size_seg,
+ adjust_reloc_syms, write_relocs): Make third argument PTR, not
+ char *, to match definition of bfd_map_over_sections.
+
+ * app.c (do_scrub_next_char): Don't interpret a comment character
+ as starting a CPP line directive unless it is a '#' and is the
+ very first characters on the line (i.e., do not permit leading
+ whitespace).
+
+ * messages.c (identify): Make file argument non-const, to match
+ callers.

* config/tc-hppa.c (pa_ip): Fix thinko in 21bit range check.
