2024-05-15[binutils/readelf] Fix printing of dwarf4 .debug_str_offsets.dwoTom de Vries3-0/+21
When compiling a hello world with dwarf4 split dwarf: ... $ gcc -gdwarf-4 -gsplit-dwarf hello.c -save-temps -dA ... we have in a-hello.s these three initial entries in .debug_str_offsets: ... .section .debug_str_offsets.dwo,"e",@progbits .4byte 0 // indexed string 0x0: short int .4byte 0xa // indexed string 0x1: /home/vries/binutils .4byte 0x1f // indexed string 0x2: main ... but "readelf -ws a.out" starts at the third entry: ... Contents of the .debug_str_offsets.dwo section (loaded from a-hello.dwo): Length: 0x30 Index Offset [String] 0 00000000 main ... This is a regression since commit 407115429b3 ("Modified changes for split-dwarf and dwarf-5."), which introduced a variable debug_str_offsets_hdr_len in display_debug_str_offsets. Fix this by setting display_debug_str_offsets to 0 for the dwarf4 case. PR 31734
2024-04-17aarch64: Remove asserts from operand qualifier decoders [PR31595]Victor Do Nascimento2-0/+4
Given that the disassembler should never abort when decoding (potentially random) data, assertion statements in the `get_*reg_qualifier_from_value' function family prove problematic. Consider the random 32-bit word W, encoded in a data segment and encountered on execution of `objdump -D <obj_name>'. If: (W & ~opcode_mask) == valid instruction Then before `print_insn_aarch64_word' has a chance to report the instruction as potentially undefined, an attempt will be made to have the qualifiers for the instruction's register operands (if any) decoded. If the relevant bits do not map onto a valid qualifier for the matched instruction-like word, an abort will be triggered and the execution of objdump aborted. As this scenario is perfectly feasible and, in light of the fact that objdump must successfully decode all sections of a given object file, it is not appropriate to assert in this family of functions. Therefore, we add a new pseudo-qualifier `AARCH64_OPND_QLF_ERR' for handling invalid qualifier-associated values and re-purpose the assertion conditions in qualifier-retrieving functions to be the predicate guarding the returning of the calculated qualifier type. If the predicate fails, we return this new qualifier and allow the caller to handle the error as appropriate. As these functions are called either from within `aarch64_extract_operand' or `do_special_decoding', both of which are expected to return non-zero values, it suffices that callers return zero upon encountering `AARCH64_OPND_QLF_ERR'. Ar present the error presented in the hypothetical scenario has been encountered in `get_sreg_qualifier_from_value', but the change is made to the whole family to keep the interface consistent.

2024-03-11tests: force non-deterministic mode in non-deterministic testsStephen Kitt1-4/+5
Since ar can be built defaulting to deterministic mode, tests which expect non-deterministic behaviour need to explicitly set the U flag. The non-deterministic member test expects SOURCE_DATE_EPOCH to not be set; this documents that. Unconditionally unsetting the variable causes issues in test infrastructure (which expects unsetenv to only be called on variables which are already set). Signed-off-by: Stephen Kitt <steve@sk2.org>

2023-07-28MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targetsYunQiang Su6-9/+20
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/+2
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. Name + Addend 000000000000 000800000002 R_MIPS_32 0000000000000000 foo + 0 Type2: R_MIPS_NONE Type3: R_MIPS_NONE and: OFFSET TYPE VALUE 0000000000000000 R_MIPS_32 foo 0000000000000000 R_MIPS_NONE *ABS* 0000000000000000 R_MIPS_NONE *ABS* respectively.

2023-04-26binutils runtest $CCAlan Modra1-1/+1
I noticed in the binutile Makefile that runtest is being invoked with CC, CC_FOR_BUILD and other compiler related flags in the environment. That doesn't work. Those variables ought to be passed on the runtest command line. After fixing that I had some fails due to binutils testprog.c now being compiled with the default "-g -O2" picked up in CFLAGS_FOR_TARGET. Hack around that by passing -O0. Also, with the binutils testsuite now taking notice of CC_FOR_TARGET, I found a couple of debuginfod.exp fails with one of my compilers that happened to be built without --debug-id being enabled by default. * Makefile.am (check-DEJAGNU): Pass $CC and other variable on the runtest command line rather than futilely in the environment. Add -O0 to CFLAGS_FOR_TARGET. * Makefile.in: Regenerate. * testsuite/binutils-all/debuginfod.exp: Compile testprog.c with -Wl,--build-id.

For MIPS64r6 ports, Debian as an example, `mipsisa64r6el` is used as the cpu name in triple. Let's recognize them by `mips*64*(el)`. For 64bit Ports, like Debian's mips64el and mips64r6el ports, `gnuabi64` is used as the abi section. Let's use N64 abi by default for the triple with gnuabi64.

2023-02-13opcodes/mips: disassemble unknown micromips instructions as two shortsAndrew Burgess5-0/+33
Before commit: commit 2438b771ee07be19d5b01ea55e077dd8b7cef445 Date: Wed Nov 2 15:53:43 2022 +0000 opcodes/mips: use .word/.short for undefined instructions unknown 32-bit microMIPS instructions were disassembled as a raw 32-bit number with no '.word' directive. The above commit changed this and added a '.word' directive before the 32-bit number. It was pointed out on the mailing list, that for microMIPS it would be better to display such 32-bit instructions using a '.short' directive followed by two 16-bit values. This commit updates the mips disassembler to do this, and adds a new test that validates this output.
2023-02-03RISC-V: don't disassemble unrecognized insns as .byteJan Beulich1-3/+3
Insn width granularity being 16 bits, producing byte granular output isn't very useful. With there being a way to specific otherwise unknown insns to the assembler, use that same representation (to be precise: its <length>,<encoding> flavor) for disassembly.

2022-12-05opcodes/mips: use .word/.short for undefined instructionsAndrew Burgess10-34/+34
While working on disassembler styling for MIPS, I noticed that undefined instructions are printed by the disassembler as raw number with no assembler directive prefix (e.g. without .word or .short). I think adding something like .word, or .short, helps to make it clearer the size of the value that is being displayed, and is inline with what many of the other libopcode disassemblers do. In this commit I've added the .word and .short directives, and updated all the tests that I spotted that failed as a result.
