2024-03-26Don't claim a fat IR object if no IR object should be claimedH.J. Lu1-3/+3
When the linker sees an input object containing nothing but IR during rescan, it should ignore it (LTO phase is over). But if the input object is a fat IR object, which has non-IR code as well, it should be used to resolve references as if it did not contain any IR at all. This patch adds lto_type to bfd and linker avoids claiming a fat IR object if no IR object should be claimed. bfd/ PR ld/23935 * archive.c (_bfd_compute_and_write_armap): Check bfd_get_lto_type instead of lto_slim_object. * elflink.c (elf_link_add_object_symbols): Likewise. * bfd.c (bfd_lto_object_type): New.

2024-03-25bfd: make _bfd_section_size_insane part of the public APIAndrew Burgess1-1/+1
If a BFD user is making use of a function like bfd_get_section_contents to read a section into a pre-allocated buffer, then that BFD user might also want to make use of _bfd_section_size_insane prior to allocating the buffer they intend to use in order to validate that the buffer size that plan to allocate is sane. This commit makes _bfd_section_size_insane public, by renaming it to bfd_section_size_insane. I've updated the existing uses within bfd/, I don't believe this function is used outside of bfd/ currently. One place that I plan to make use of this function is in gdb/gdb_bfd.c, in the function gdb_bfd_get_full_section_contents. This change isn't included in this commit, but will come later if/when this has been merged into bfd. There should be no change in behaviour after this commit. bfd/ * bfd-in2.h (bfd_section_size_insane): Add declaration. * compress.c (bfd_get_full_section_contents): Update for new name of _bfd_section_size_insane.

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>

2024-03-01s390: Print base register 0 as "0" in disassemblyJens Remus1-0/+2
Base and index register 0 have no effect in address computation: "A value of zero in the B [base] or X [index] field specifies that no base or index is to be applied, and, thus, general register 0 cannot be designated as containing a base address or index." IBM z/Architecture Principles of Operation [1], chapter "Organization", section "General Registers". Index register 0 is omitted in the s390 disassembly. Base register 0 is omitted in D(B), D(L,B) and D(X,B) - the latter only if the index register is zero. To make it more apparent print base register 0 as "0" instead of "%r0", whenever it would still be printed in the disassembly.

2024-02-08PR 31283 windmc: Parse input correctly on big endian hostsRichard W.M. Jones4-4/+259
On big endian hosts (eg. s390x) the windmc tool fails to parse even trivial files: $ cat test.mc ; $ ./binutils/windmc ./test.mc In test.mc at line 1: parser: syntax error. In test.mc at line 1: fatal: syntax error. The tool starts by reading the input as Windows CP1252 and then converting it internally into an array of UTF-16LE, which it then processes as an array of unsigned short (typedef unichar). There are lots of ways this is wrong, but in the specific case of big endian machines the little endian pairs of bytes are byte-swapped. For example, the ';' character in the input above is first converted to UTF16-LE byte sequence { 0x3b, 0x00 }, which is then cast to unsigned short. On a big endian machine the first unichar appears to be 0x3b00. The lexer is unable to recognize this as the comment character ((unichar)';') and so parsing fails. The simple fix is to convert the input to UTF-16BE on big endian machines (and do the reverse conversion when writing the output).

2023-12-06PR31096, nm shows 32bit addresses as 64bit addressesAlan Modra1-35/+44
Prior to commit 0e3c1eebb2 nm output depended on the host unsigned long when printing "negative" symbol values for 32-bit targets. Commit 0e3c1eebb22 made the output match that seen with a 64-bit host unsigned long. The fact that nm output changed depending on host is of course a bug, but it is reasonable to expect 32-bit target output is only 32 bits. So this patch makes 32-bit target output the same as it was on 32-bit hosts prior to 0e3c1eebb2. PR 31096 * nm.c (print_format_string): Make it a static buffer. (get_print_format): Merge into..

2023-12-04Fix two buglets in .debug_names dumpingTom Tromey2-3/+13
While working on gdb's .debug_names writer, I found a couple of small bugs in binutils .debug_names dumping. First, the DWARF spec (section 6.1.1.4.6 Name Table) says: These two arrays are indexed starting at 1, [...] I think it is clearer for binutils to follow this, particularly because DW_IDX_parent refers to this number. Second, I think the handling of an empty hash table is slightly wrong. Currently the dumping code assumes there is always an array of hashes. However, section 6.1.1.4.5 Hash Lookup Table says: The optional hash lookup table immediately follows the list of type signatures. and then: The hash lookup table is actually two separate arrays: an array of buckets, followed immediately by an array of hashes. My reading of this is that the hash table as a whole is optional, and so the hashes will not exist in this case. (This also makes sense because the hashes are not useful without the buckets anyway.) This patch fixes both of these problems. FWIW I have some gdb patches in progress that change gdb both to omit the hash table and to use DW_IDX_parent. 2023-12-04 Tom Tromey <tom@tromey.com> * dwarf.c (display_debug_names): Handle empty .debug_names hash table.

Add support for jump visualization for the s390 architecture in disassembly: objdump -d --visualize-jumps ... Annotate the (conditional) jump and branch relative instructions with information required for jump visualization: - jump: Unconditional jump / branch relative. - condjump: Conditional jump / branch relative. - jumpsr: Jump / branch relative to subroutine. Unconditional jump and branch relative instructions are annotated as jump. Conditional jump and branch relative instructions, jump / branch relative on count/index, and compare and jump / branch relative instructions are annotated as condjump. Jump and save (jas, jasl) and branch relative and save (bras, brasl) instructions are annotated as jumpsr (jump to subroutine). Provide instruction information required for jump visualization during disassembly. The instruction type is provided after determining the opcode. For non-code it is set to dis_noninsn. Otherwise it defaults to dis_nonbranch. No annotation is done for data reference instructions (i.e. instruction types dis_dref and dis_dref2). Note that the instruction type needs to be provided before printing of the instruction, as it is used in print_address_func() to translate the argument value into an address if it is assumed to be a PC-relative offset. Note that this is never the case on s390, as print_address_func() is only called with addresses and never with offsets. The target of the (conditional) jump and branch relative instructions is provided during print, when the PC relative operand is decoded. include/ * opcode/s390.h: Define opcode flags to annotate instruction class information for jump visualization: S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE, S390_INSTR_FLAG_CLASS_CONDITIONAL, and S390_INSTR_FLAG_CLASS_SUBROUTINE.

2023-11-20Restore .gdb_index v9 display in readelfTom Tromey1-8/+49
