From 19f785835e5e97a7c666e8f942cb4ec8e543aebc Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 5 Sep 2001 02:39:43 +0000 Subject: [PATCH] * config/tc-alpha.c (struct alpha_insn): Make sequence scalar long. (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. --- gas/ChangeLog | 32 + gas/config/tc-alpha.c | 1380 +++++++++++++-------------------- gas/config/tc-alpha.h | 20 +- gas/testsuite/ChangeLog | 11 + gas/testsuite/gas/alpha/alpha.exp | 33 + gas/testsuite/gas/alpha/elf-reloc-1.d | 21 + gas/testsuite/gas/alpha/elf-reloc-1.s | 16 + gas/testsuite/gas/alpha/elf-reloc-2.l | 4 + gas/testsuite/gas/alpha/elf-reloc-2.s | 8 + gas/testsuite/gas/alpha/elf-reloc-3.l | 3 + gas/testsuite/gas/alpha/elf-reloc-3.s | 2 + gas/testsuite/gas/alpha/elf-reloc-4.d | 25 + gas/testsuite/gas/alpha/elf-reloc-4.s | 4 + gas/testsuite/gas/alpha/fp.d | 6 +- gas/testsuite/gas/alpha/fp.exp | 15 - gas/testsuite/gas/alpha/fp.s | 2 +- 16 files changed, 731 insertions(+), 851 deletions(-) create mode 100644 gas/testsuite/gas/alpha/alpha.exp create mode 100644 gas/testsuite/gas/alpha/elf-reloc-1.d create mode 100644 gas/testsuite/gas/alpha/elf-reloc-1.s create mode 100644 gas/testsuite/gas/alpha/elf-reloc-2.l create mode 100644 gas/testsuite/gas/alpha/elf-reloc-2.s create mode 100644 gas/testsuite/gas/alpha/elf-reloc-3.l create mode 100644 gas/testsuite/gas/alpha/elf-reloc-3.s create mode 100644 gas/testsuite/gas/alpha/elf-reloc-4.d create mode 100644 gas/testsuite/gas/alpha/elf-reloc-4.s delete mode 100644 gas/testsuite/gas/alpha/fp.exp diff --git a/gas/ChangeLog b/gas/ChangeLog index 0e61a6b..65232cc 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,35 @@ +2001-08-04 Richard Henderson + + * config/tc-alpha.c (struct alpha_insn): Make sequence scalar long. + (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.
