From ae57792d90d18306c9e470b9ecc245cdeef389f4 Mon Sep 17 00:00:00 2001 From: Hans-Peter Nilsson Date: Thu, 4 Nov 2004 15:00:37 +0000 Subject: * configure.in (crisv32): Recognize. AC_DEFINE_UNQUOTED DEFAULT_CRIS_ARCH. Handle crisv32-*-linux-gnu* like cris-*-linux-gnu* and crisv32-*-* like cris-*-*. * configure: Regenerate. * config/tc-cris.c (enum cris_archs): New. (cris_mach, cris_arch_from_string, s_cris_arch, get_sup_reg) (cris_insn_ver_valid_for_arch): New functions. (DEFAULT_CRIS_ARCH): New macro, default to cris_any_v0_v10. (cris_arch): New variable. (md_pseudo_table): New pseudo .arch. (err_for_dangerous_mul_placement): Initialize according to DEFAULT_CRIS_ARCH. (STATE_COND_BRANCH): Renamed from STATE_CONDITIONAL_BRANCH. All users changed. (STATE_COND_BRANCH_V32, STATE_COND_BRANCH_COMMON) (STATE_ABS_BRANCH_V32, STATE_LAPC, BRANCH_BF_V32, BRANCH_BB_V32) (BRANCH_WF_V32, BRANCH_WB_V32): New. (BRANCH_BF, BRANCH_BB, BRANCH_WF, BRANCH_WB): Don't undef after use in md_cris_relax_table. (md_cris_relax_table): Add entries for STATE_COND_BRANCH_V32, STATE_COND_BRANCH_COMMON, STATE_ABS_BRANCH_V32, STATE_LAPC. Update and improve head comment. (OPTION_PIC): Define in terms of previous option, OPTION_US. (OPTION_MULBUG_ABORT_ON, OPTION_MULBUG_ABORT_OFF): Similar. (OPTION_ARCH): New. (md_longopts): New option --march=... (cris_any_v0_v10_long_jump_size, crisv32_long_jump_size): New macros. (md_long_jump_size): Initialize in terms of DEFAULT_CRIS_ARCH. (HANDLE_RELAXABLE): New macro. (md_estimate_size_before_relax): Use HANDLE_RELAXABLE for common cases. Check for weak symbols and assume not relaxable. Handle STATE_COND_BRANCH_V32, STATE_COND_BRANCH_COMMON, STATE_ABS_BRANCH_V32, STATE_LAPC. Use new variable symbolP, not fragP->fr_symbol. (md_convert_frag): Handle STATE_COND_BRANCH_V32, STATE_COND_BRANCH_COMMON, STATE_ABS_BRANCH_V32, STATE_LAPC. (cris_create_short_jump): Adjust for CRISv32. (md_create_long_jump): Ditto. Emit error for common_v10_v32. (md_begin): Define symbols "..asm.arch.cris.v32", "..asm.arch.cris.v10", "..asm.arch.cris.common_v10_v32" and "..asm.arch.cris.any_v0_v10". Use cris_insn_ver_valid_for_arch when entering opcode table entry points. (md_assemble): Adjust branch handling for CRISv32. Handle LAPC relaxation. In fix_new_exp call for main insn, pass 1 for pcrel parameter for 8, 16 and 32-bit pc-relative insns and LAPC. (cris_process_instruction): Initialize out_insnp->insn_type to CRIS_INSN_NONE, not CRIS_INSN_NORMAL. : New cases. : Check that modified_char == '.'. : Consume the rest of the line. When operands don't match, skip over subsequent insns with non-matching version specifier but same mnemonic. : Immediate operands for special registers in CRISv32 are always 32 bit long. : New cases. (get_gen_reg): Only recognize "PC" when followed by "+]" for v32 and compatible. Recognize "ACR" for v32, unless followed by "+". (get_spec_reg): Consider cris_arch when looking up register. (get_autoinc_prefix_or_indir_op): Don't recognize assignment for v32 or compatible. (get_3op_or_dip_prefix_op): Check for ']' after seeing '[rN+'. (cris_get_expression): Restore input_line_pointer if failing "early". (get_flags): Consider cris_arch and recognize flags accordingly. (branch_disp): Adjust for CRISv32. (gen_cond_branch_32): Similar. Emit error for common_v10_v32. (cris_number_to_imm): Use as_bad_where, not as_bad. Remove related FIXME. Don't insist on BFD_RELOC_32_PCREL fixup to be resolved. Don't enter zeros in object file for BFD_RELOC_32_PCREL. : New case. (md_parse_option): Break out "return 1". New case. (tc_gen_reloc): : New cases. Addends for non-zero fx_pcrel are too in fx_offset. (md_show_usage): Show --march=. (md_apply_fix3): Adjust val for BFD_RELOC_CRIS_LAPCQ_OFFSET. (md_pcrel_from): BFD_RELOC_CRIS_LAPCQ_OFFSET is PC-relative too. (s_syntax) : Properly constify member operand. * config/tc-cris.h (TARGET_MACH): Define. (cris_mach): Declare. * doc/as.texinfo (Overview) : Add --march=... * doc/c-cris.texi (CRIS-Symbols): New node for built-in symbols. (CRIS-Opts): Document --march=... (CRIS-Pseudos): Document .arch. --- gas/doc/as.texinfo | 1 + 1 file changed, 1 insertion(+) (limited to 'gas/doc/as.texinfo') diff --git a/gas/doc/as.texinfo b/gas/doc/as.texinfo index 280fb32..26dd5e9 100644 --- a/gas/doc/as.texinfo +++ b/gas/doc/as.texinfo @@ -276,6 +276,7 @@ gcc(1), ld(1), and the Info entries for @file{binutils} and @file{ld}.
