(elf32_arm_copy_private_bfd_data): Copy EABI object attributes. (elf32_arm_fake_sections): Handle .ARM.attributes. (elf32_arm_parse_attributes): New function. (elf32_arm_section_from_shdr): Use it. (bfd_elf32_bfd_final_link): Define. gas/ * config/tc-arm.c: Don't provide fallback default for CPU_DEFAULT. (arm_arch_used, thumb_arch_used, selected_cpu, selected_cpu_name): New variables. (arm_cpu_option_table): Add canonical_name. (arm_cpus): Populate canonical_name field. (s_arm_eabi_attribute, s_arm_arch, s_arm_cpu, s_arm_fpu, aeabi_set_public_attributes, arm_md_end): New functions. (md_pseudo_table): Add "cpu", "arch", "fpu" and "eabi_attribute". (md_assemble): Set thumb_arch_used and arm_arch_used. (md_begin): Set defaut cpu if CPU_DEFAULT not defined. * config/tc-arm.h (md_end): Define. * doc/c-arm.texi: Document .cpu, .arch, .fpu and .eabi_attribute. gas/testsuite/ * gas/arm/eabi_attr_1.s: New test. * gas/arm/eabi_attr_1.d: New test. * gas/arm/arm7t.d: Only disassemble code sections. * gas/arm/bignum1.d: Ignore Arm object attribute sections. * gas/arm/mapping.d: Ditto. * gas/arm/unwind.d: Ditto. * gas/elf/section0.d: Ditto. * gas/elf/section1.d: Ditto. * gas/elf/elf.exp: Set target_machine for Arm EABI based targets. * gas/elf/section2.e-armeabi: New file. include/elf/ * arm.h: Add prototypes for BFD object attribute routines. ld/testsuite/ * ld-arm/arm-rel31.d: Ignore Arm object attribute sections. * ld-arm/arm-target1-abs.d: Ditto. * ld-arm/arm-target1-rel.d: Ditto. * ld-arm/arm-target2-abs.d: Ditto. * ld-arm/arm-target2-got-rel.d: Ditto. * ld-arm/arm-target2-rel.d: Ditto. --- include/elf/ChangeLog | 4 ++++ include/elf/arm.h | 48 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 52 insertions(+) diff --git a/include/elf/ChangeLog b/include/elf/ChangeLog index 310e99752..cf4b57805 100644 --- a/include/elf/ChangeLog +++ b/include/elf/ChangeLog @@ -1,3 +1,7 @@ +2005-10-08 Paul Brook + + * arm.h: Add prototypes for BFD object attribute routines. + 2005-09-09 Richard Earnshaw * arm.h (SHT_ARM_PREEMPTMAP, SHT_ARM_ATTRIBUTES): New defines. diff --git a/include/elf/arm.h b/include/elf/arm.h index c4bfaf287..2d76ab643 100644 --- a/include/elf/arm.h +++ b/include/elf/arm.h @@ -223,6 +223,54 @@ START_RELOC_NUMBERS (elf_arm_reloc_type) FAKE_RELOC (R_ARM_PC13, R_ARM_LDR_PC_G0) /* Unclear whether meaning is different. */ END_RELOC_NUMBERS (R_ARM_max) +#ifdef BFD_ARCH_SIZE +/* Routines for manipulating EABI object attributes. */ +void elf32_arm_add_eabi_attr_int (bfd *, int, unsigned int); +void elf32_arm_add_eabi_attr_string (bfd *, int, const char *); +void elf32_arm_add_eabi_attr_compat (bfd *, unsigned int, const char *); + +void elf32_arm_set_eabi_attr_contents (bfd *, bfd_byte *, bfd_vma); +bfd_vma elf32_arm_eabi_attr_size (bfd *); + +enum +{ + Tag_NULL, + Tag_File, + Tag_Section, + Tag_Symbol, + Tag_CPU_raw_name, + Tag_CPU_name, + Tag_CPU_arch, + Tag_CPU_arch_profile, + Tag_ARM_ISA_use, + Tag_THUMB_ISA_use, + Tag_VFP_arch, + Tag_WMMX_arch, + Tag_NEON_arch, + Tag_PCS_config, + Tag_ABI_PCS_R9_use, + Tag_ABI_PCS_RW_data, + Tag_ABI_PCS_RO_data, + Tag_ABI_PCS_GOT_use, + Tag_ABI_PCS_wchar_t, + Tag_ABI_FP_rounding, + Tag_ABI_FP_denormal, + Tag_ABI_FP_exceptions, + Tag_ABI_FP_user_exceptions, + Tag_ABI_FP_number_model, + Tag_ABI_align8_needed, + Tag_ABI_align8_preserved, + Tag_ABI_enum_size, + Tag_ABI_HardFP_use, + Tag_ABI_VFP_args, + Tag_ABI_WMMX_args, + Tag_ABI_optimization_goals, + Tag_ABI_FP_optimization_goals, + Tag_compatibility, +}; + +#endif + /* The name of the note section used to identify arm variants. */ #define ARM_NOTE_SECTION ".note.gnu.arm.ident"
