(MACRO_LITERAL, MACRO_BASE, MACRO_BYTOFF, MACRO_JSR): Remove. (alpha_macros): Remove occurrences of same. (O_lituse_addr, O_gprel): New. (DUMMY_RELOC_LITUSE_*): New. (s_alpha_ucons, s_alpha_arch): Prototype. (alpha_reloc_op): Construct elements via DEF macro. (ALPHA_RELOC_SEQUENCE_OK): Remove. (struct alpha_reloc_tag): Rename from alpha_literal_tag; rename members to not be literal specific. (next_sequence_num): New. (md_apply_fix3): Cope with missing GPDISP_LO16. Adjust for added/removed BFD relocations. (alpha_force_relocation, alpha_fix_adjustable): Likewise. (alpha_adjust_symtab_relocs): Handle GPDISP relocs as well. (tokenize_arguments): Parse ! relocations properly. (find_macro_match): Delete unused macro argument types. (assemble_insn): Add reloc parameter; emit that instead of the default as appropriate. (get_alpha_reloc_tag): New. Split from ... (emit_insn): ... here. Allocate a reloc tag for GPDISP. (assemble_tokens): Don't search macros if user relocation present. Copy reloc sequence number to insn struct. (emit_ldgp): Remove user reloc handling. (load_expression, emit_lda, emit_ldah, emit_ir_load): Likewise. (emit_loadstore, emit_ldXu, emit_ldil, emit_stX): Likewise. (emit_sextX, emit_division, emit_jsrjmp, emit_retjcr): Likewise. * config/tc-alpha.h (tc_adjust_symtab): Always define. (struct alpha_fix_tag): Name members less literal specific. * gas/alpha/alpha.exp: New file. * gas/alpha/elf-reloc-1.[sd]: New test. * gas/alpha/elf-reloc-2.[sl]: New test. * gas/alpha/elf-reloc-3.[sl]: New test. * gas/alpha/elf-reloc-4.[sd]: New test. * gas/alpha/fp.exp: Remove file. * gas/alpha/fp.s: Output to .data not .rdata. * gas/alpha/fp.d: Adjust to match.
