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.
2023-12-29LoongArch: bfd: Add support for tls le relax.changjiachen1-5/+50
Add tls le relax support and related relocs in bfd. New relocation related explanation can refer to the following url: https://github.com/loongson/la-abi-specs/blob/release/laelf.adoc This support does two main things: 1. Implement support for three new relocation items in bfd. The three new relocation items are shown below: R_LARCH_TLS_LE_ADD_R R_LARCH_TLS_LE_HI20_R R_LARCH_TLS_LE_LO12_R 2. ADD a new macro RELOCATE_TLS_TP32_HI20 Handle problems caused by symbol extensions in TLS LE, The processing is similar to the macro RELOCATE_CALC_PC32_HI20 method. 3. Implement the tls le relax function. bfd/ChangeLog: * bfd-in2.h: Add relocs related to tls le relax. * elfnn-loongarch.c: (loongarch_relax_tls_le): New function. (RELOCATE_TLS_TP32_HI20): New macro. (loongarch_elf_check_relocs): Add new reloc support. (perform_relocation): Likewise. (loongarch_elf_relocate_section): Handle new relocs related to relax. (loongarch_elf_relax_section): Likewise. * elfxx-loongarch.c: (LOONGARCH_HOWTO (R_LARCH_TLS_LE_ADD_R)): New reloc how to type. (LOONGARCH_HOWTO (R_LARCH_TLS_LE_HI20_R)): Likewise. (LOONGARCH_HOWTO (R_LARCH_TLS_LE_LO12_R)): Likewise. * libbfd.h: Add relocs related to tls le relax. * reloc.c: Likewise.
2023-12-27asan: buffer overflow in loongarch_elf_rtype_to_howtoAlan Modra1-21/+11
Seen when running ld-loongarch-elf/tlsdesc-dso test. elfxx-loongarch.c:1844:32: runtime error: index 125 out of bounds for type 'loongarch_reloc_howto_type [124]' So either the loongarch_howto_table needs three more LOONGARCH_EMPTY_HOWTO entries, or loongarch_elf_rtype_to_howto should be testing for r_type < ARRAY_SIZE (loongarch_howto_table). I figure it's worth wasting a little more space to get faster lookup. * elfxx-loongarch.c (loongarch_howto_table): Add LOONGARCH_EMPTY_HOWTO entries for 121..123. (loongarch_elf_rtype_to_howto): Don't support slow lookup. Assert exact table size and r_type indexing. Omit return cast. (loongarch_reloc_name_lookup): Omit assertion and return cast. (loongarch_reloc_type_lookup): Likewise.
2023-12-25LoongArch: Add support for TLS LD/GD/DESC relaxationmengqinggang1-0/+60
The pcalau12i + addi.d of TLS LD/GD/DESC relax to pcaddi. Relaxation is only performed when the TLS model transition is not possible.
2023-12-25LoongArch: Add new relocs and macro for TLSDESC.Lulu Cai1-2/+208
The normal DESC instruction sequence is: pcalau12i $a0,%desc_pc_hi20(var) #R_LARCH_TLS_DESC_PC_HI20 addi.d $a0,$a0,%desc_pc_lo12(var) #R_LARCH_TLS_DESC_PC_LO12 ld.d $ra,$a0,%desc_ld(var) #R_LARCH_TLS_DESC_LD jirl $ra,$ra,%desc_call(var) #R_LARCH_TLS_DESC_CALL add.d $a0,$a0,$tp
2023-12-22LoongArch: Add support for the third expression of .align for R_LARCH_ALIGNmengqinggang1-3/+7
If the symbol index is not zero, the addend is used to represent the first and the third expressions of the .align. The lowest 8 bits are used to represent the first expression. Other bits are used to represent the third expression. The addend of R_LARCH_ALIGN for ".align 5, ,4" is 0x405. The addend of R_LARCH_ALIGN for ".balign 32, ,4" is 0x405.
2023-12-18LoongArch: Add new relocation R_LARCH_CALL36mengqinggang1-0/+24
R_LARCH_CALL36 is used for medium code model function call pcaddu18i+jirl, and these two instructions must adjacent. The LoongArch ABI v2.20 at here: https://github.com/loongson/la-abi-specs.
2023-11-22LoongArch: fix internal error when as handling unsupported modifier.Lulu Cai1-3/+0
2023-10-24as: fixed internal error when immediate value of relocation overflow.Lulu Cai1-6/+16
The as and ld use _bfd_error_handler to output error messages when checking relocation alignment and relocation overflow. However, the abfd value passed by as to the function is NULL, resulting in an internal error. The ld passes a non-null value to the function, so it can output an error message normally.
2023-09-27Add support for "pcaddi rd, symbol"mengqinggang1-2/+2
Add a macro pcaddi instruction to support "pcaddi rd, symbol". pcaddi has a 20-bit signed immediate, it can address a +/- 2MB pc relative address, and the address should be 4-byte aligned.

2023-06-16LoongArch: Fix ld "undefined reference" error with --enable-sharedmengqinggang1-0/+7
Because _bfd_read_unsigned_leb128 is hidden visibility, so it can't be referenced out of shared object.

2022-06-08Revert reloc howto nitsAlan Modra1-3/+3
The "HOWTO size encoding" patch put 1 as the HOWTO size arg for numerous howtos that are unused, describe dynamic relocs, are markers, or otherwise are special purpose reloc howtos that don't care about the size. The idea was to ensure no howto changed by inspecting object files.

This changes the HOWTO macro to encode the howto.size field from a value given in bytes.
