[binutils, ARM, 16/16] Add support to VLDR and VSTR of system registers GNU as' Arm backend assumes each mnemonic has a single entry in the instruction table but VLDR (system register) and VSTR (system register) are different instructions than VLDR and VSTR. It is thus necessary to add some form of demultiplexing in the parser. It starts by creating a new operand type OP_VLDR which indicate that the operand is either the existing OP_RVSD operand or a system register. The function parse_operands () then tries these two cases in order, calling the new parse_sys_vldr_vstr for the second case. Since the encoding function is specified in the instruction table entry, it also need to have some sort of demultiplexing. This is done in do_vldr_vstr which either calls the existing do_neon_ldr_str () or calls the new do_t_vldr_vstr_sysreg (). A new internal relocation is needed as well since the offset has a shorter range than in other Thumb coprocessor instructions. Disassembly also requires special care since VSTR (system register) reuse the STC encoding with the coprocessor number 15. Armv8.1-M Mainline ARM manual states that coprocessor 8, 14 and 15 are reserved for floating-point and MVE instructions a feature bit check is added if the coprocessor number is one of this value and we are trying to match a coprocessor instruction (eg. STC) to forbid the match.

[binutils, ARM, 15/16] Add support for VSCCLRM Like for CLRM, this patch aims to share as much logic with the similar looking VLDM/VSTM. This is achieved by adding 2 new enumerator values in enum reg_list_els for the single-precision and double-precision variants of VSCCLRM and extending parse_vfp_reg_list () to deal with these types. These behave like the existing REGLIST_VFP_S and REGLIST_VFP_D types with extra logic to expect VPR as the last element in the register list. The function is algo augmented with a new partial_match parameter to indicate if any register other than VPR had already been parsed in the register list so as to not try parsing the second variant if that's the case and return the right error message. The rest of the patch is the usual encoding function, new disassembler table entries and format specifier and parsing, encoding and disassembling tests. It is worth mentioning that the new entry in the disassembler table was added in the coprocessor-related table despite VSCCLRM always being available even in FPU-less configurations. The main reason for this is that VSCCLRM also match VLDMIA entry and must thus be tried first but coprocessor entries are tried before T32 entries. It also makes sense because it is in the same encoding space as coprocessor and VFP instructions and is thus the natural place for someone to look for this instruction. Note: Both variants of VSCCLRM support D16-D31 registers but Armv8.1-M Mainline overall does not. I have thus decided not to implement support for these registers in order to keep the code simpler. It can always be added later if needed.

[opcodes, ARM, 14/16] Add mode availability to coprocessor table entries The coprocessor_opcodes table is used both to share commonalities in coprocessor-related instructions and to avoid duplication between Arm and Thumb mode. However, some instructions do have differences between Arm and Thumb. For instance, vldmia allows PC as base register in Arm mode but not in Thumb mode. In that very case the distinction becomes necessary because the encoding with PC as base register is used in Thumb mode to denote a VSCCLRM. It is thus necessary to distinguish what is Arm or Thumb only from what is shared. This patch adds an extra field to the coprocessor_opcodes table entries to indicate what mode is a given instruction available in. The print_insn_coprocessor then uses that field to determine if an entry that matched the mark and value checked should be allowed to match or not given the current mode. ChangeLog entry is as follows: *** opcodes/ChangeLog *** 2019-04-15 Thomas Preud'homme <thomas.preudhomme@arm.com> * arm-dis.c (enum isa): New enum. (struct sopcode32): New structure.

[binutils, ARM, 13/16] Add support for CLRM Given the similarity between LDM/STM and CLRM register lists, most of the changes in this patch aim at sharing code between those two sets of instruction. Sharing is achieved both in parsing and encoding of those instructions. In terms of parsing, parse_reg_list () is extended to take a type that describe what type of instruction is being parsed. The reg_list_els used for parse_vfp_reg_list () is reused for the type and that function is added an assert for the new REGLIST_CLRM and REGLIST_RN enumerators. parse_reg_list () is then taught to accept APSR and reject SP and PC when parsing for a CLRM instruction. At last, caller of parse_reg_list () is updated accordingly and logic is added for the new OP_CLRMLST operand. Encoding-wise, encode_thumb2_ldmstm () is reused to encode the variable bits of CLRM and is thus renamed encode_thumb2_multi (). A new do_io parameter is added to distinguish between LDM/STM and CLRM which guard all the LDM/STM specific code of the function. Finally objdump is told how to disassemble CLRM, again reusing the logic to print the LDM/STM register list (format specifier 'm'). Tests are also added in the form of negative tests to check parsing and encoding/disassembling tests.

PowerPC bc extended branch mnemonics and "y" hints This patch fixes a problem with disassembly of branch instructions for processors complying with PowerPC ISA versions prior to version 2.0, ie. those that use "y" bit branch taken hints. Many of the extended bcctr and bclr mnemonics that should have disassembled with a "-" suffix, ie. not taken, did not display the "-" due to the ordering in powerpc_opcodes. I believe it's been that way from the original 85dcf36d72b commit of ppc-opc.c. I've also added a BH field (optional) to a few opcodes. This gives better disassembly in raw mode, showing the branch taken hint in the mnemonic as is done for bc. It would be reasonable to add a BH field to all bcctr, bclr, and bctar extended mnemonics but that runs into a small difficulty: Currently we print all or none of the optional operands. That means for example that "bgectr cr2" would display as "bgectr cr2,0" if a BH field is added to bgectr. * ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK. (powerpc_opcodes): Reorder bcctr and bclr extended mnemonics to favour printing of "-" branch hint when using the "y" bit. Allow BH field on bc{ctr,lr,tar}{,l}{-,+}.

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.

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.

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.

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).

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.

Arm: Backport hlt to all architectures. The software trap instruction HLT that was introduced in Armv8-a is used as the semihosting trap instruction in AArch64. In order to allow systems configured to run AArch64 code to also run AArch32 with semihosting it was decided that AArch32 should also use HLT in the case of the "mixed mode" environment. This requires that HLT also be backported to all earlier architectures. The instruction is in the undefined encoding space earlier architectures but must trigger a semihosting trap [3]. The Arm Architectural Reference Manual [1] doesn't explicitly mention this however this is an explicit requirement in the Semihosting-v2 protocol [2].
