From a0351a698b33aea0c0cec14ae44070a45bac6329 Mon Sep 17 00:00:00 2001 From: Doug Kwan Date: Thu, 10 Dec 2009 20:55:33 +0000 Subject: 2009-12-10 Doug Kwan elfcpp/ChangeLog * arm.h: New enums for EABI object attribute tags and values. gold/ChangeLog * arm.cc (attributes.h): New include. (Arm_relobj::Arm_relobj): Initialize attributes_section_data_. (Arm_relobj::~Arm_relobj): Delete object pointed by attributes_section_data_. (Arm_relobj::attributes_section_data): New method definition. (Arm_relobj::attributes_section_data_): New data member declaration. (Arm_dynobj::Arm_dynobj): Initialize attributes_section_data_. (Arm_dynobj::~Arm_dynobj): Delete object pointed by attributes_section_data_. (Arm_dynobj::attributes_section_data): New method definition. (Arm_dynobj::attributes_section_data_): New data member declaration. (Target_arm::Target_arm): Initialize attributes_section_data_. Change initialization value of may_use_blx_ to false. (Target_arm::using_thumb2, Target_arm::using_thumb_only, Target_arm::may_use_arm_nop, Target_arm::may_use_thumb2_nop): Use object attributes to compute results instead of hard-coding. (Target_arm::do_attribute_arg_type, Target_arm::do_attributes_order, Target_arm::get_secondary_compatible_arch, Target_arm::set_secondary_compatible_arch Target_arm::tag_cpu_arch_combine, Target_arm::aeabi_enum_name, Target_arm::tag_cpu_name_value, Target_arm::merge_object_attributes): New method declarations. (Target_arm::get_aeabi_object_attribute): New method definition. (Target_arm::attributes_section_data_): New data member declaration. (read_arm_attributes_section): New template definition. (Arm_relobj::do_read_symbols): Read attributes section if it exists. (Arm_dynobj::do_read_symbols): Ditto. (Target_arm::do_finalize_sections): Merge attributes sections from input. Check for BLX use after attributes section merging. Fix __exidx_start and __exidx_end visibility. Create an .ARM.attributes section if necessary. (Target_arm::get_secondary_compatible_arch, Target_arm::set_secondary_compatible_arch, Target_arm::tag_cpu_arch_combine, Target_arm::aeabi_enum_name, Target_arm::tag_cpu_name_value, Target_arm::merge_object_attributes, Target_arm::do_attribute_arg_type, Target_arm::do_attributes_order): New method definitions. --- elfcpp/ChangeLog | 4 +++ elfcpp/arm.h | 76 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 80 insertions(+) (limited to 'elfcpp') diff --git a/elfcpp/ChangeLog b/elfcpp/ChangeLog index 653a863..ca6b78b 100644 --- a/elfcpp/ChangeLog +++ b/elfcpp/ChangeLog @@ -1,3 +1,7 @@ +2009-12-10 Doug Kwan + + * arm.h: New enums for EABI object attribute tags and values. + 2009-12-05 Doug Kwan * arm.h: Define enums for Tag_CPU_arch EABI attribute. diff --git a/elfcpp/arm.h b/elfcpp/arm.h index 52b80c5..08a17ad 100644 --- a/elfcpp/arm.h +++ b/elfcpp/arm.h @@ -245,6 +245,82 @@ enum TAG_CPU_ARCH_V4T_PLUS_V6_M = (MAX_TAG_CPU_ARCH + 1) }; +// EABI object attributes. +enum +{ + // 0-3 are generic. + Tag_CPU_raw_name = 4, + Tag_CPU_name = 5, + Tag_CPU_arch = 6, + Tag_CPU_arch_profile = 7, + Tag_ARM_ISA_use = 8, + Tag_THUMB_ISA_use = 9, + Tag_VFP_arch = 10, + Tag_WMMX_arch = 11, + Tag_Advanced_SIMD_arch = 12, + Tag_PCS_config = 13, + Tag_ABI_PCS_R9_use = 14, + Tag_ABI_PCS_RW_data = 15, + Tag_ABI_PCS_RO_data = 16, + Tag_ABI_PCS_GOT_use = 17, + Tag_ABI_PCS_wchar_t = 18, + Tag_ABI_FP_rounding = 19, + Tag_ABI_FP_denormal = 20, + Tag_ABI_FP_exceptions = 21, + Tag_ABI_FP_user_exceptions = 22, + Tag_ABI_FP_number_model = 23, + Tag_ABI_align8_needed = 24, + Tag_ABI_align8_preserved = 25, + Tag_ABI_enum_size = 26, + Tag_ABI_HardFP_use = 27, + Tag_ABI_VFP_args = 28, + Tag_ABI_WMMX_args = 29, + Tag_ABI_optimization_goals = 30, + Tag_ABI_FP_optimization_goals = 31, + // 32 is generic (Tag_compatibility). + Tag_undefined33 = 33, + Tag_CPU_unaligned_access = 34, + Tag_undefined35 = 35, + Tag_VFP_HP_extension = 36, + Tag_undefined37 = 37, + Tag_ABI_FP_16bit_format = 38, + Tag_undefined39 = 39, + Tag_nodefaults = 64, + Tag_also_compatible_with = 65, + Tag_T2EE_use = 66, + Tag_conformance = 67, + Tag_Virtualization_use = 68, + Tag_undefined69 = 69, + Tag_MPextension_use = 70 +}; + +// Values for Tag_ABI_PCS_R9_use. +enum +{ + AEABI_R9_V6 = 0, + AEABI_R9_SB = 1, + AEABI_R9_TLS = 2, + AEABI_R9_unused = 3 +}; + +// Values for Tag_ABI_PCS_RW_data. +enum +{ + AEABI_PCS_RW_data_absolute = 0, + AEABI_PCS_RW_data_PCrel = 1, + AEABI_PCS_RW_data_SBrel = 2, + AEABI_PCS_RW_data_unused = 3 +}; + +// Values for Tag_ABI_enum_size. +enum +{ + AEABI_enum_unused = 0, + AEABI_enum_short = 1, + AEABI_enum_wide = 2, + AEABI_enum_forced_wide = 3 +}; + } // End namespace elfcpp. #endif // !defined(ELFCPP_ARM_H) -- cgit v1.1
