Tamar Christina	fab7c86ea4	AArch64: Add SVE DWARF registers The SVE DRAWF register names are missing from binutils, this may cause objdump and readelf to ignore certain DRAWF output as the registers are unknown (most notably CIEs). This patch adds the registers in accordance to the "DWARF for ARM(r) 64-bit Architecture (AARch64) with SVE support" documentation [1].

Tamar Christina	05805feba2	AArch64/Arm: Update testcases fixing endiannes and linux targets This fixes the testcases that are failing due to my recent patch. It turns out that the start address across baremetal and linux builds isn't entirely predictable without a linker script. Since the address themselves are not the important thing I am ignoring them now. Secondly I was encoding data using .word using non 0 values, however because .word is subjected to endiannes these non-zero values under big-endian happen to fall into the encoding space of instructions which changes the disassembly. Using 0 fixes this problem and the purpose of the test still holds, though objdump will dump ... for data only sections, which is ok as the data/insn mixed sections will test the patch. The ARM Attributes sections is not important and is ignored. binutils/ChangeLog: * testsuite/binutils-all/aarch64/in-order.d: Likewise. * testsuite/binutils-all/aarch64/out-of-order-all.d: Likewise. * testsuite/binutils-all/aarch64/out-of-order.d: Likewise. * testsuite/binutils-all/aarch64/out-of-order.s: Likewise. * testsuite/binutils-all/arm/in-order-all.d: Likewise. * testsuite/binutils-all/arm/in-order.d: Likewise. * testsuite/binutils-all/arm/out-of-order-all.d: Likewise. * testsuite/binutils-all/arm/out-of-order.d: Likewise. * testsuite/binutils-all/arm/out-of-order.s: Likewise.	7 years ago

Tamar Christina	796d6298bb	Arm: Fix Arm disassembler mapping symbol search. Similar to the AArch64 patches the Arm disassembler has the same issues with out of order sections but also a few short comings. For one thing there are multiple code blocks to determine mapping symbols, and they all work slightly different, and neither fully correct. The first thing this patch does is centralise the mapping symbols search into one function mapping_symbol_for_insn. This function is then updated to perform a search in a similar way as AArch64. Their used to be a value has_mapping_symbols which was used to determine the default disassembly for objects that have no mapping symbols. The problem with the approach was that it was determining this value in the same loop that needed it, which is why this field could take on the states -1, 0, 1 where -1 means "don't know". However this means that until you actually find a mapping symbol or reach the end of the disassembly glob, you don't know if you did the right action or not, and if you didn't you can't correct it anymore. This is why the two jump-reloc-veneers-* testcases end up disassembling some insn as data when they shouldn't. Out of order here refers to an object file where sections are not listed in a monotonic increasing VMA order. The ELF ABI for Arm [1] specifies the following for mapping symbols: 1) A text section must always have a corresponding mapping symbol at it's start. 2) Data sections do not require any mapping symbols. 3) The range of a mapping symbol extends from the address it starts on up to the next mapping symbol (exclusive) or section end (inclusive). However there is no defined order between a symbol and it's corresponding mapping symbol in the symbol table. This means that while in general we look up for a corresponding mapping symbol, we have to make at least one check of the symbol below the address being disassembled. When disassembling different PCs within the same section, the search for mapping symbol can be cached somewhat. We know that the mapping symbol corresponding to the current PC is either the previous one used, or one at the same address as the current PC. However this optimization and mapping symbol search must stop as soon as we reach the end or start of the section. Furthermore if we're only disassembling a part of a section, the search is a allowed to search further than the current chunk, but is not allowed to search past it (The mapping symbol if there, must be at the same address, so in practice we usually stop at PC+4). lastly, since only data sections don't require a mapping symbol the default mapping type should be DATA and not INSN as previously defined, however if the binary has had all its symbols stripped than this isn't very useful. To fix this we determine the default based on the section flags. This will allow the disassembler to be more useful on stripped binaries. If there is no section than we assume you to be disassembling INSN.

Tamar Christina	60df3720d7	AArch64: Have -D override mapping symbol as documented. The documentation for -D says that on Arm platforms -D should disassemble data as instructions. "If the target is an ARM architecture this switch also has the effect of forcing the disassembler to decode pieces of data found in code sections as if they were instructions. " This makes it do as it says on the tincan so it's more consistent with aarch32. The usecase here is for baremetal developers who have created their instructions using .word directives instead if .insn. Though for Linux users I do find this behavior somewhat non-optimal. Perhaps there should be a new flag that just disassembles the values following the actual mapping symbol? binutils/ChangeLog: * testsuite/binutils-all/aarch64/in-order-all.d: New test. * testsuite/binutils-all/aarch64/out-of-order-all.d: New test. * testsuite/binutils-all/aarch64/out-of-order.d: opcodes/ChangeLog: * aarch64-dis.c (print_insn_aarch64): Implement override.	7 years ago
Tamar Christina	5145776164	AArch64: Fix AArch64 disassembler mapping symbol search My previous patch for AArch64 was not enough to catch all the cases where disassembling an out-of-order section could go wrong. It had missed the case DATA sections could be incorrectly disassembled as TEXT. Out of order here refers to an object file where sections are not listed in a monotonic increasing VMA order. The ELF ABI for AArch64 [1] specifies the following for mapping symbols: 1) A text section must always have a corresponding mapping symbol at it's start. 2) Data sections do not require any mapping symbols. 3) The range of a mapping symbol extends from the address it starts on up to the next mapping symbol (exclusive) or section end (inclusive).

Tamar Christina	53b2f36bf6	AArch64: Fix disassembler bug with out-of-order sections The AArch64 disassembler has an optimization that it uses to reduce the amount it has to search for mapping symbols during disassembly. This optimization assumes that sections are listed in the section header in monotonic increasing VMAs. However this is not a requirement for the ELF specification. Because of this when such "out of order" sections occur the disassembler would pick the wrong mapping symbol to disassemble the section with. This fixes it by explicitly passing along the stop offset for the current disassembly glob and when this changes compared to the previous one we've seen the optimization won't be performed. In effect this restarts the search from a well defined starting point. Usually the symbol's address. The existing stop_vma can't be used for this as it is allowed to be unset and setting this unconditionally would change the semantics of this field. binutils/ChangeLog: * objdump.c (disassemble_bytes): Pass stop_offset. * testsuite/binutils-all/aarch64/out-of-order.T: New test. * testsuite/binutils-all/aarch64/out-of-order.d: New test. * testsuite/binutils-all/aarch64/out-of-order.s: New test. include/ChangeLog: * dis-asm.h (struct disassemble_info): Add stop_offset. opcodes/ChangeLog: * aarch64-dis.c (last_stop_offset): New.

Sudakshina Das	37c18eedff	[BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI enabled PLTs This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds a new ld command line option: --force-bti. In the presence of this option, the linker enables BTI with the GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning in case of missing gnu notes for BTI in inputs. 2) It also defines a new set of BTI enabled PLTs. These are used either when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI or when the new --force-bti option is used. This required adding new fields in elf_aarch64_link_hash_table so that we could make the PLT related information more generic. 3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses this whenever it picks BTI enabled PLTs.

Sudakshina Das	cd702818c6	[BFD, LD, AArch64, 1/3] Add support for GNU PROPERTIES in AArch64 for BTI and PAC This is part of the patch series to add support for BTI and PAC in AArch64 linker. This patch implements the following: 1) This extends in the gnu property support in the linker for AArch64 by defining backend hooks for elf_backend_setup_gnu_properties, elf_backend_merge_gnu_properties and elf_backend_parse_gnu_properties. 2) It defines AArch64 specific GNU property GNU_PROPERTY_AARCH64_FEATURE_1_AND and 2 bit for BTI and PAC in it. 3) It also adds support in readelf.c to read and print these new GNU properties in AArch64.

Alan Modra	7a6e0d89bb	Don't use bfd_get_file_size in objdump Compressed debug sections can have uncompressed sizes that exceed the original file size, so we can't use bfd_get_file_size. objdump also used bfd_get_file_size to limit reloc section size, but I believe the underlying bug causing the PR22508 out of bounds buffer access was that we had an integer overflow when calculating the reloc buffer size. I've fixed that instead in most of the backends, som and vms-alpha being the exceptions. SOM and vmd-alpha have rather more serious bugs in their slurp_relocs routines that would need fixing first if we want to fuss about making them safe against fuzzed object files.

This allows checking the command line parsing more easily than before by allowing many command line invokations from the same .d file. Each line is used as a set of flags, and the tests are ran against the output of the assembler with each set.

Andrew Burgess	46cbf38dc3	binutils: Add new GNU format mode to `size` utility The size tool currently defaults to berkeley format output. However, this output format has a weird quirk, read-only data is counted against the text sections, not the data sections. The code offers no real explanation for why this is, but I'm reluctant to change it for two reasons, first, I'm assuming it probably makes sense in some case that I'm not thinking of (maybe a target where sections are not marked executable, and so there's no distinction between read-only data and code), and second, the code has been this way for at least 20 years, I worry that changing things now might cause more confusion than it solves. This commit then introduces a new output format for the size tool, this new format displays the results in a similar manor to the berkeley format, but counts read-only data in the data column, and only executable sections are counted in the text column. Given that this is a brand new output format I've gone ahead and simplified things a little, while the berkeley format displays the total twice, once in decimal and once in hex, the new display format just displays the total in decimal. Of course, there's still the '--radix' option which can be used to display all the results in hexadecimal or octal. I've called the new format 'gnu', so '--format=gnu' or '-G' are used to access it. binutils/ChangeLog: * size.c (berkeley_format): Delete. (enum output_format): New enum.
