2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

2022-11-12PowerPC64 paddi -MrawAlan Modra1-10/+10
On a testcase like pla 8,foo@pcrel disassembled with -Mpower10 results in 0: 00 00 10 06 pla r8,0 # 0 4: 00 00 00 39 0: R_PPC64_PCREL34 foo but with -Mpower10 -Mraw 0: 00 00 10 06 .long 0x6100000 0: R_PPC64_PCREL34 foo 4: 00 00 00 39 addi r8,0,0 The instruction is unrecognised due to the hack we have in extract_pcrel0 in order to disassemble paddi with RA0=0 and R=1 as pla. I could have just added "&& !(dialect & PPC_OPCODE_RAW)" to the condition in extract_pcrel0 under which *invalid is set, but went for this larger patch that reorders the extended insn pla to the more usual place before its underlying machine insn. (la is after addi because we never disassemble to la.) gas/ * testsuite/gas/ppc/raw.d, * testsuite/gas/ppc/raw.s: Add pla. opcodes/ * ppc-opc.c (extract_pcrel1): Rename from extract_pcrel0 and invert *invalid logic.

2022-10-16PowerPC se_rfmci and VLE, SPE2 and LSP insns with -manyAlan Modra1-1/+5
I noticed recently that se_rfmci, a VLE mode instruction, was being accepted by non-VLE cpus, and also that se_rfmci by itself in a section did not cause SHF_PPC_VLE to be set. ie. both testcases added by this patch fail without the changes to tc-ppc.c here.

2022-10-14PowerPC SPE disassembly and testsAlan Modra1-2/+2
Where sub and subf forms of an instruction exist we generally disassemble to the extended insn sub form rather than the underlying machine subf instruction. Do so for SPE evsubw and evsubiw too. spe_ambiguous.d always was a bit too optimistic. There is no sensible way to disassemble identical bytes back to different and original source. Instead change the test to check -Mraw results. gas/ * testsuite/gas/ppc/ppc.exp: Run spe_ambiguous test. * testsuite/gas/ppc/spe.d: Expect evsubw and evsubiw rather than evsubfw and evsubifw. * testsuite/gas/ppc/spe_ambiguous.s: Test evnor form equivalent to evnot. * testsuite/gas/ppc/spe_ambiguous.d: Test Mraw. opcodes/ * ppc-opc.c (powerpc_opcodes): Move evsubw before evsubfw and evsubiw before evsubifw and mark EXT.
2022-10-14e200 LSP supportAlan Modra1-332/+332
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.

This patch adds support for LibreSOC machine and SVP64 extension flag for PowerPC architecture. SV (Simple-V) is a strict RISC-paradigm Scalable Vector Extension for the Power ISA. SVP64 is the 64-bit Prefixed instruction format implementing SV. 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.

2022-07-21PowerPC: Create new MMA instruction masks and use themPeter Bergner1-33/+39
The MMA instructions use XX3_MASK|3<<21 as an instruction mask, but that misses the RC bit/bit 31, so if we disassemble a .long that represents an MMA instruction except that it also has bit 31 set, we will erroneously disassemble it to that MMA instruction.

2022-03-16PowerPC64 extended instructions in powerpc_macrosAlan Modra1-19/+245
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. (Or many occurrences in the case of clrlsldi if n <= b was added to the extract functions.)

2021-04-08PR27676, PowerPC missing extended dcbt, dcbtst mnemonicsAlan Modra1-7/+82
Note that this doesn't implement the ISA to the letter regarding dcbtds (and dcbtstds), which says that the TH field may be zero. That doesn't make sense because allowing TH=0 would mean you no long have a dcbtds but rather a dcbtct instruction. I'm interpreting the ISA wording about allowing TH=0 to mean that the TH field of dcbtds is optional (in which case the TH value is 0b1000). opcodes/ PR 27676 * ppc-opc.c (DCBT_EO): Move earlier. (insert_thct, extract_thct, insert_thds, extract_thds): New functions. (powerpc_operands): Add THCT and THDS entries.

2021-01-09POWER10: Add Return-Oriented Programming instructionsPeter Bergner1-1/+45
POWER10 adds some return-oriented programming (ROP) instructions and this patch adds support for them. You will notice that they are enabled for POWER8 and later, not just POWER10 and later. This is on purpose. This allows the instructions to be added to POWER8 binaries that can be run on POWER8, POWER9 and POWER10 cpus. On POWER8 and POWER9, these instructions just act as nop's. opcodes/ * ppc-opc.c (insert_dw, (extract_dw): New functions. (DW, (XRC_MASK): Define.
