The elf32-kvx.c and elf64-kvx.c rules in the bfd makefile are different to the other similar generated files, and that reminded me that we need to have $srcdir in the generated #line reference back to the source for debugging, but don't want it for comments in bfd.pot (because then bfd.pot will likely reference Nick's source tree).

2023-07-28MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targetsYunQiang Su5-8/+30
Make the n64 ABI the default for 64-bit Linux targets specified with `-gnuabi64' suffix included in the target triplet, for configurations such as the Debian mips64el and mips64r6el ports. Adjust testsuite configuration accordingly. There are the following regressions with the new target triplet: mips64-linux-gnuabi64 +FAIL: readelf -S bintest mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 mips64el-linux-gnuabi64 +FAIL: readelf -S bintest mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 The `readelf' issue comes from a difference in section headers produced that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template does not match. While there has been a precedent it does not appear to me that there is a clear advantage from adding more and more variations to the template rather than forking the existing template into multiple ones for a more exact match. So this is best deferred to a separate discussion. The MIPS reloc estimation issue is an actual bug in `objdump', which discards a number of trailing entries from output here for n64 composed relocations: DYNAMIC RELOCATION RECORDS OFFSET TYPE VALUE 0000000000000000 R_MIPS_NONE *ABS* 0000000000000000 R_MIPS_NONE *ABS* and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not match even though ELF output produced is correct according to `readelf': Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries: Offset Info Type Sym.

2023-07-28testsuite: Handle composed R_MIPS_NONE relocationsYunQiang Su1-0/+4
MIPS n64 ABI has a peculiarity where all relocations are composed of three, with subsequent relocation types set to R_MIPS_NONE if further calculation is not required. Example output produced by `readelf' and `objdump' for such relocations is: Offset Info Type Sym. Value Sym.

2023-07-28MIPS/LD/testsuite: Fix MIPS16 interlinking test IRIX 6 regressionsMaciej W. Rozycki1-1/+2
IRIX 6 does not have MIPS16 stub section support in its n32 linker scripts, causing such input sections to be propagated to the respective output sections rather than `.text', causing dump pattern mismatches. Expect IRIX 6 to fail with n32 testing then, removing this regression: mips-sgi-irix6 -FAIL: MIPS16 interlinking for local functions 1 (n32) We may choose to update IRIX 6 n32 linker scripts sometime, as it seems a harmless change. ld/ * testsuite/ld-mips-elf/mips-elf.exp: Expect IRIX 6 to fail with n32 `mips16-local-stubs-1' testing.

The `got-dump-1' test case uses 32-bit addressing, so it makes no sense to run it with the n64 ABI. And there is a corresponding `got-dump-2' test already for the n64 ABI.

2023-07-28MIPS/LD/testsuite: Fix `attr-gnu-4-10' failures with IRIX targetsMaciej W. Rozycki1-0/+1
IRIX targets do not enable the production of a `.pdr' section in GAS by default, which causes a failure with the `attr-gnu-4-10' test case due to a difference resulting in the number and indices of sections produced in linker output. As the presence or absence of this section is not relevant to this test case, just enable it unconditionally, fixing these regressions: mips-sgi-irix5 -FAIL: ld-mips-elf/attr-gnu-4-10 mips-sgi-irix6 -FAIL: ld-mips-elf/attr-gnu-4-10 ld/ * testsuite/ld-mips-elf/attr-gnu-4-10.d: Add `as' tag with `-mpdr'.
2023-07-28MIPS/LD/testsuite: Fix JALR relaxation test failure with IRIX 6Maciej W. Rozycki4-10/+9
The `mips-sgi-irix6' target only supports IRIX linker emulations, but most JALR relaxation tests request the relevant traditional emulation instead, causing a link failure: ./ld-new: unrecognised emulation mode: elf32btsmipn32 Supported emulations: elf32bmipn32 elf32bsmip elf64bmip This is clearly an omission from the conversion to use the per-ABI framework made with commit 78da84f99405 ("MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement"). These tests are also endianness agnostic, which was missed in the conversion as well. Remove the unnecessary explicit ABI and endianness options then and rely on the per-ABI framework to get things right, removing this regression: mips-sgi-irix6 -FAIL: MIPS relax-jalr-shared n32 ld/ * testsuite/ld-mips-elf/relax-jalr-n32-shared.d: Remove flags related to ABI and endianness selection from the `as' and `ld' tags. * testsuite/ld-mips-elf/relax-jalr-n64.d: Likewise. * testsuite/ld-mips-elf/relax-jalr-n64-shared.d: Likewise. * testsuite/ld-mips-elf/mips-elf.exp: Remove `as' and `ld' tag additions from the invocation of JALR relaxation tests.
2023-07-28MIPS/LD/testsuite: Fix unaligned JALX failures with OpenBSD targetsMaciej W. Rozycki9-16/+24
There are only n64 linker emulations included with `mips64*-*-openbsd*' targets, however the unaligned JALX tests insist on running across all targets and force the n32 ABI, causing link errors with the targets concerned, e.g.: ./ld-new: tmpdir/unaligned-jalx-0.o: ABI is incompatible with that of the selected emulation ./ld-new: failed to merge target specific data of file tmpdir/unaligned-jalx-0.o ./ld-new: tmpdir/unaligned-insn.o: ABI is incompatible with that of the selected emulation ./ld-new: failed to merge target specific data of file tmpdir/unaligned-insn.o Convert the tests then to use the per-ABI framework and run them for the o32 and n32 ABIs, removing these regressions: mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 0 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 1 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 2 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 3 mips64-openbsd -FAIL: MIPS16 JALX to unaligned symbol 0 mips64-openbsd -FAIL: MIPS16 JALX to unaligned symbol 1 mips64-openbsd -FAIL: microMIPS JALX to unaligned symbol 0 mips64-openbsd -FAIL: microMIPS JALX to unaligned symbol 1 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 0 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 1 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 2 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 3 mips64el-openbsd -FAIL: MIPS16 JALX to unaligned symbol 0 mips64el-openbsd -FAIL: MIPS16 JALX to unaligned symbol 1 mips64el-openbsd -FAIL: microMIPS JALX to unaligned symbol 0 mips64el-openbsd -FAIL: microMIPS JALX to unaligned symbol 1 Similar tests for the n64 ABI can be added separately, using suitable dump patterns. ld/ * testsuite/ld-mips-elf/unaligned-jalx-0.d: Remove `-32' from the `as' tag. * testsuite/ld-mips-elf/unaligned-jalx-1.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-2.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-3.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-mips16-0.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-micromips-0.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d: Likewise. * testsuite/ld-mips-elf/mips-elf.exp: Run unaligned JALX tests with `run_dump_test_o32' and `run_dump_test_n32' rather than `run_dump_test'.
2023-07-28MIPS/LD: Include n64 `.interp' with INITIAL_READONLY_SECTIONSYunQiang Su18-7/+559
In ld/emulparams/elf64bmip-defs.sh there is no explicit handling of the `.interp' section, which causes it to be positioned in output at an odd place. Let's include it with INITIAL_READONLY_SECTIONS, just like o32/n32 do, fixing a regression from commit 5a8e7be242f3 ("INITIAL_READONLY_SECTIONS in elf.sc"), where the handling of n64 was missed due to an unfortunate sequence of events where ld/emulparams/elf64bmip-defs.sh was only added with commit 94bb04b3c611 ("Use .reginfo rather than .MIPS.options in n32 linker scripts") the day before.

This reverts commit 32f1c80375ebe8ad25d9805ee5889f0006c51e59. It had two unrelated changes lumped together, one of which changed the meaning of the `mipsisa64*-*-linux*' target triplets, which was not properly evaluated.

2023-07-21DesCGENization of the BPF binutils portJose E. Marchesi4-7/+7
CGEN is cool, but the BPF architecture is simply too bizarre for it. The weird way of BPF to handle endianness in instruction encoding, the weird C-like alternative assembly syntax, the weird abuse of multi-byte (or infra-byte) instruction fields as opcodes, the unusual presence of opcodes beyond the first 32-bits of some instructions, are all examples of what makes it a PITA to continue using CGEN for this port. The bpf.cpu file is becoming so complex and so nested with p-macros that it is very difficult to read, and quite challenging to update. Also, every time we are forced to change something in CGEN to accommodate BPF requirements (which is often) we have to do extensive testing to make sure we do not break any other target using CGEN. This is getting un-maintenable. So I have decided to bite the bullet and revamp/rewrite the port so it no longer uses CGEN. Overall, this involved: * To remove the cpu/bpf.{cpu,opc} descriptions. * To remove the CGEN generated files. * To replace the CGEN generated opcodes table with a new hand-written opcodes table for BPF. * To replace the CGEN generated disassembler wih a new disassembler that uses the new opcodes. * To replace the CGEN generated assembler with a new assembler that uses the new opcodes. * To replace the CGEN generated simulator with a new simulator that uses the new opcodes. [This is pushed in GDB in another patch.] * To adapt the build systems to the new situation. Additionally, this patch introduces some extensions and improvements: * A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF relocation R_BPF_GNU_64_16 are added to the BPF BFD port. These relocations are used for section-relative 16-bit offsets used in load/store instructions. * The disassembler now has support for the "pseudo-c" assembly syntax of BPF. What dialect to use when disassembling is controlled by a command line option. * The disassembler now has support for dumping instruction immediates in either octal, hexadecimal or decimal. The used output base is controlled by a new command-line option. * The GAS BPF test suite has been re-structured and expanded in order to test the disassembler pseudoc syntax support. Minor bugs have been also fixed there. The assembler generic tests that were disabled for bpf-*-* targets due to the previous implementation of pseudoc syntax are now re-enabled. Additional tests have been added to test the new features of the assembler. .dump files are no longer used. * The linker BPF test suite has been adapted to the command line options used by the new disassembler. The result is very satisfactory. This patchs adds 3448 lines of code and removes 10542 lines of code. Tested in: * Target bpf-unknown-none with 64-bit little-endian host and 32-bit little-endian host. * Target x86-64-linux-gnu with --enable-targets=all Note that I have not tested in a big-endian host yet. I will do so once this lands upstream so I can use the GCC compiler farm. I have not included ChangeLog entries in this patch: these would be massive and not very useful, considering this is pretty much a rewrite of the port. I beg the indulgence of the global maintainers.
