2019-04-05PowerPC bc extended branch mnemonics and "y" hintsAlan Modra2-141/+148
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}{-,+}.

2019-03-25Arm: Fix Arm disassembler mapping symbol search.Tamar Christina2-148/+107
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.

2019-03-25AArch64: Have -D override mapping symbol as documented.Tamar Christina2-1/+7
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.
2019-03-25AArch64: Fix AArch64 disassembler mapping symbol searchTamar Christina2-6/+43
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).

2019-03-25AArch64: Fix disassembler bug with out-of-order sectionsTamar Christina2-1/+11
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.

2019-02-07Arm: Backport hlt to all architectures.Tamar Christina2-1/+6
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].

2018-12-06sim/opcodes: Allow use of out of tree cgen source directoryAndrew Burgess3-8/+26
When configuring with '--enbale-cgen-maint' the default for both the opcodes/ and sim/ directories is to assume that the cgen source is within the binutils-gdb source tree as binutils-gdb/cgen/. In the old cvs days, this worked well, as cgen was just another sub-module of the single cvs repository and could easily be checked out within the binutils-gdb directory, and managed by cvs in the normal way. Now that binutils-gdb is in git, while cgen is still in cvs, placing the cgen respository within the binutils-gdb tree is more troublesome, and it would be nice if the two tools could be kept separate. Luckily there is already some initial code in the configure.ac files for both opcodes/ and sim/ to support having cgen be located outside of the binutils-gdb tree, however, this was speculative code written imagining a future where cgen would be built and installed to some location. Right now there is no install support for cgen, and so the configure code in opcodes/ and sim/ doesn't really do anything useful. In this commit I repurpose this code to allow binutils-gdb to be configured so that it can make use of a cgen source directory that is outside of the binutils-gdb tree. With this commit applied it is now possible to configure and build binutils-gdb like this: /path/to/binutils-gdb/src/configure --enable-cgen-maint=/path/to/cgen/src/cgen/ make all-opcodes make -C opcodes run-cgen-all Just in case anyone is still using cgen inside the binutils-gdb tree, I have left the default behaviour of '--enable-cgen-maint' (with no parameter) unchanged, that is it looks for the cgen directory as 'binutils-gdb/cgen/'. opcodes/ChangeLog: * configure.ac (enable-cgen-maint): Support passing path to cgen source tree. * configure: Regenerate. sim/ChangeLog: * common/acinclude.m4 (enable-cgen-maint): Support passing path to cgen source tree. * cris/configure: Regenerate. * frv/configure: Regenerate. * iq2000/configure: Regenerate. * lm32/configure: Regenerate. * m32r/configure: Regenerate. * or1k/configure: Regenerate. * sh64/configure: Regenerate.
2018-12-06opcodes/riscv: Hide '.L0 ' fake symbolsAndrew Burgess3-0/+28
The RISC-V assembler generates fake labels with the name '.L0 ' as part of the debug information (see gas/config/tc-riscv.h:FAKE_LABEL_NAME). The problem is that currently, when disassembling an object file, the output looks like this (this is an example from the GDB testsuite, but is pretty representative of anything with debug information): 000000000000001e <main>: 1e: 7179 addi sp,sp,-48 20: f406 sd ra,40(sp) 22: f022 sd s0,32(sp) 24: 1800 addi s0,sp,48 0000000000000026 <.L0 >: 26: 87aa mv a5,a0 28: feb43023 sd a1,-32(s0) 2c: fcc43c23 sd a2,-40(s0) 30: fef42623 sw a5,-20(s0) 0000000000000034 <.L0 >: 34: fec42783 lw a5,-20(s0) 38: 0007871b sext.w a4,a5 3c: 678d lui a5,0x3 3e: 03978793 addi a5,a5,57 # 3039 <.LASF30+0x2a9d> 42: 02f71463 bne a4,a5,6a <.L0 > 0000000000000046 <.L0 >: 46: 000007b7 lui a5,0x0 4a: 0007b783 ld a5,0(a5) # 0 <need_malloc> 4e: 6f9c ld a5,24(a5) 0000000000000050 <.L0 >: 50: 86be mv a3,a5 52: 466d li a2,27 54: 4585 li a1,1 56: 000007b7 lui a5,0x0 5a: 00078513 mv a0,a5 5e: 00000097 auipc ra,0x0 62: 000080e7 jalr ra # 5e <.L0 +0xe> 0000000000000066 <.L0 >: 66: 4785 li a5,1 68: a869 j 102 <.L0 > 000000000000006a <.L0 >: 6a: 000007b7 lui a5,0x0 6e: 00078513 mv a0,a5 72: 00000097 auipc ra,0x0 76: 000080e7 jalr ra # 72 <.L0 +0x8> The frequent repeated '.L0 ' labels are pointless, as they are non-unique there's no way to match a use of '.L0 ' to its appearence in the output, so we'd be better off just not printing it at all.

ARM Architecture Reference Manual for the profile ARMv8-A, Issue C.a, states that MOV (register) is an alias of the ORR (shifted register) iff shift == '00' && imm6 == '000000' && Rn == '11111'. However, mov is currently preferred for a broader range of orr instructions, which is incorrect. 2018-12-03 Egeyar Bagcioglu <egeyar.bagcioglu@oracle.com> opcodes: PR 23193 PR 19721 * aarch64-tbl.h (aarch64_opcode_table): Only disassemble an ORR encoding as MOV if the shift operation is a left shift of zero. gas: PR 23193 PR 19721 * testsuite/gas/aarch64/pr19721.s: Add new test cases. * testsuite/gas/aarch64/pr19721.d: Correct existing test cases and add new ones.

2018-11-21S12Z opcodes: Fix bug disassembling certain shift instructions.John Darrington2-19/+30
Shift and rotate instructions when the number of bit positions was an immediate value greater than 1 were incorrectly disassembled. This change fixes that problem and extends the test to check for it. gas/ChangeLog: testsuite/gas/s12z/shift.s: Add new test case. testsuite/gas/s12z/shift.d: Add expected result. opcodes/ChangeLog: s12z-dis.c (print_insn_shift) [SB_REG_REG_N]: Enter special case if the postbyte matches the appropriate pattern.
2018-11-13opcodes/nfp: Fix disassembly of crc[] with swapped operands.Francois H. Theron2-6/+10
The decoding of the CRC operation in alu instructions was using bits from the instruction word directly, instead of srcA which would be different if the swap bit was set. Signed-off-by: Francois H. Theron <francois.theron@netronome.com>
