Tsukasa OI	15253318be	RISC-V: Add 'Ssstateen' extension and its CSRs This commit adds 'Ssstateen' extension, which is a supervisor-visible view of the 'Smstateen' extension. It means, this extension implements sstateen* and hstateen* CSRs of the 'Smstateen' extension. Note that 'Smstateen' extension itself is unchanged but due to implementation simplicity, it is implemented so that 'Smstateen' implies 'Ssstateen' (just like 'M' implies 'Zmmul'). This is based on the latest version of RISC-V Profiles (version 0.9-draft, Frozen): <`226b7f6430`> bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets): Update implication rules.

Alan Modra	61a457e5da	e200 LSP support It has bothered me for a long time that we have disabled LSP (and SPE) tests. Also the LSP test comment indicating there is something wrong with get_powerpc_dialect. I don't think there is. Decoding of a VLE instruction depends on whether the processor is in VLE mode (some processors support both VLE and standard PPC) which we flag per section with SHF_PPC_VLE for decoding when disassembling. Background: Some versions of powerpc e200 have "Lightweight Signal Processing" support, examples being e200z215 and e200z425. As far as I can tell, LSP and SPE are mutually exclusive. This seems to be borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw" have the same encoding. So none of the processor descriptions in ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we want disassembly to work. I also could not find anything to suggest that the LSP insns are enabled only in VLE mode, which means the LSP insns should not be in vle_opcodes. Fix all this by moving the LSP insns to their own table, and add a new e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from -mvle. (Yes, I know, as I said above some of the e200z4 processors have LSP. Others have SPE. It's hard to choose good options. Think of z2 as meaning earlier, z4 as later.) Also add -mlsp to allow adding the LSP insn set. include/ * opcode/ppc.h (lsp_opcodes, lsp_num_opcodes): Declare.

Funded by NLnet through EU Grants No: 825310 and 825322, SV is in DRAFT form and is to be publicly submitted via the OpenPOWER Foundation ISA Working Group via the newly-created External RFC Process.

Andrew Burgess	76a4c1e063	libopcodes/aarch64: add support for disassembler styling This commit enables disassembler styling for AArch64. After this commit it is possible to have objdump style AArch64 disassembler output (using --disassembler-color option). Once the required GDB patches are merged, GDB will also style the disassembler output. The changes to support styling are mostly split between two files opcodes/aarch64-dis.c and opcodes/aarch64-opc.c. The entry point for the AArch64 disassembler can be found in aarch64-dis.c, this file handles printing the instruction mnemonics, and assembler directives (e.g. '.byte', '.word', etc). Some operands, mostly relating to assembler directives are also printed from this file. This commit changes all of this to pass through suitable styling information. However, for most "normal" instructions, the instruction operands are printed using a two step process. From aarch64-dis.c, in the print_operands function, the function aarch64_print_operand is called, this function is in aarch64-opc.c, and converts an instruction operand into a string. Then, back in print_operands (aarch64-dis.c), the operand string is printed. Unfortunately, the string returned by aarch64_print_operand can be quite complex, it will include syntax elements, like '[' and ']', in addition to register names and immediate values. In some cases, a single operand will expand into what will appear (to the user) as multiple operands separated with a ','. This makes the task of styling more complex, all these different components need to by styled differently, so we need to get the styling information out of aarch64_print_operand in some way. The solution that I propose here is similar to the solution that I used for the i386 disassembler. Currently, aarch64_print_operand uses snprintf to write the operand text into a buffer provided by the caller. What I propose is that we pass an extra argument to the aarch64_print_operand function, this argument will be a structure, the structure contains a callback function and some state. When aarch64_print_operand needs to format part of its output this can be done by using the callback function within the new structure, this callback returns a string with special embedded markers that indicate which mode should be used for each piece of text. Back in aarch64-dis.c we can spot these special style markers and use this to split the disassembler output up and apply the correct style to each piece. To make aarch64-opc.c clearer a series of new static functions have been added, e.g. 'style_reg', 'style_imm', etc. Each of these functions formats a piece of text in a different style, 'register' and 'immediate' in this case. Here's an example taken from aarch64-opc.c of the new functions in use: snprintf (buf, size, "[%s, %s]!", style_reg (styler, base), style_imm (styler, "#%d", opnd->addr.offset.imm)); The aarch64_print_operand function is also called from the assembler to aid in printing diagnostic messages. Right now I have no plans to add styling to the assembler output, and so, the callback function used in the assembler ignores the styling information and just returns an plain string. I've used the source files in gas/testsuite/gas/aarch64/ for testing, and have manually gone through and checked that the styling looks reasonable, however, I'm not an AArch64 expert, so it is possible that the odd piece is styled incorrectly. Please point out any mistakes I've made. With objdump disassembler color turned off, there should be no change in the output after this commit.	4 years ago

Andrew Burgess	6837a663c5	opcodes/aarch64: split off creation of comment text in disassembler The function aarch64_print_operand (aarch64-opc.c) is responsible for converting an instruction operand into the textual representation of that operand. In some cases, a comment is included in the operand representation, though this (currently) only happens for the last operand of the instruction. In a future commit I would like to enable the new libopcodes styling for AArch64, this will allow objdump and GDB[1] to syntax highlight the disassembler output, however, having operands and comments combined in a single string like this makes such styling harder. In this commit, I propose to extend aarch64_print_operand to take a second buffer. Any comments for the instruction are written into this extra buffer. The two callers of aarch64_print_operand are then updated to pass an extra buffer, and print any resulting comment. In this commit no styling is added, that will come later. However, I have adjusted the output slightly. Before this commit some comments would be separated from the instruction operands with a tab character, while in other cases the comment was separated with two single spaces. After this commit I use a single tab character in all cases. This means a few test cases needed updated. If people would prefer me to move everyone to use the two spaces, then just let me know. Or maybe there was a good reason why we used a mix of styles, I could probably figure out a way to maintain the old output exactly if that is critical. Other than that, there should be no user visible changes after this commit.

Alan Modra	42952a9605	PowerPC64 extended instructions in powerpc_macros The extended instructions implemented in powerpc_macros aren't used by the disassembler. That means instructions like "sldi r3,r3,2" appear in disassembly as "rldicr r3,r3,2,61", which is annoying since many other extended instructions are shown. Note that some of the instructions moved out of the macro table to the opcode table won't appear in disassembly, because they are aliases rather than a subset of the underlying raw instruction. If enabled, rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all occurrences of rotldi, rldicl, rldicr, rldic and rldimi.

Alan Modra	a2c5833233	Update year range in copyright notice of binutils files The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out /po/.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.	4 years ago
