2024-03-13RISC-V: Add -march=help for gasHau Hsu2-0/+49
Use -march=help for gas to print all supported extensions and versions. Here is part of the output of `as -march=help`: All available -march extensions for RISC-V: e 1.9 i 2.1, 2.0 m 2.0 a 2.1, 2.0 f 2.2, 2.0 d 2.2, 2.0 q 2.2, 2.0 c 2.0 v 1.0 h 1.0 zicbom 1.0 zicbop 1.0 ... This patch assumes that the supported extensions with the same versions are listed together. For example: static struct riscv_supported_ext riscv_supported_std_ext[] = { ... {"i", ISA_SPEC_CLASS_20191213, 2, 1, 0 }, {"i", ISA_SPEC_CLASS_20190608, 2, 1, 0 }, {"i", ISA_SPEC_CLASS_2P2, 2, 0, 0 }, ... }; For the "i" extension, 2.1.0 with different spec class are listed together. This patch records the previous printed extension and version. If the current extension and version are the same as the previous one, skip printing. bfd/ * elfxx-riscv.c (riscv_print_extensions): New function. Print available extensions and versions. * elfxx-riscv.h (riscv_print_extensions): New declaration. gas/ * gas/config/tc-riscv.c (md_parse_option): Parse 'help' keyword in -march option to print available extensions and versions. * testsuite/gas/riscv/march-help.l: New testcase for -march=help. * testsuite/gas/riscv/riscv.exp: Updated.

2024-03-06LoongArch: Add dtpoff calculation functionLulu Cai1-1/+11
When tls_sec is NULL, we should not access the virtual address of tls_sec.
2024-03-06LoongArch: Delete extra instructions when TLS type transitionLulu Cai1-167/+253
This modification mainly changes the timing of type transition, adds relaxation to the old LE instruction sequence, and fixes bugs in extreme code models. We strictly distinguish between type transition and relaxation. Type transition is from one type to another, while relaxation is the removal of instructions under the same TLS type. Detailed instructions are as follows: 1. For type transition, only the normal code model of DESC/IE does type transition, and each relocation is accompanied by a RELAX relocation. Neither abs nor extreme will do type transition, and no RELAX relocation will be generated. The extra instructions when DESC transitions to other TLS types will be deleted during the type transition. 2. Implemented relaxation for the old LE instruction sequence. The first two instructions of LE's 32-bit and 64-bit models use the same relocations and cannot be distinguished based on relocations. Therefore, for LE's instruction sequence, any code model will try to relax. 3. Some function names have been adjusted to facilitate understanding, parameters have been adjusted, and unused macros have been deleted.

2024-02-28PR23881, pdp11 binutils fails if too much debug dataAlan Modra4-7/+60
The PR testcase overflows one of the exec header fields, e_syms (the size of the symbol table), leading to the string table offset being wrong. Things go downhill from there. Fixed by checking for overflow. This happens to trigger in the ld testsuite, so xfail that test.

2024-02-27s390: Add r_offset check to the weak undef changeAndreas Krebbel1-1/+2

2024-02-24Make is_relocatable_executable only affect dynamic section symsAlan Modra1-11/+2
I believe the only elflink.c specialties for is_relocatable_executable needed by tic6x are those directly related to dynamic section symbols. I might be wrong, the code in record_dynamic_symbol and record_link_assignment predated the tic6x port, but I think these were symbian specific hacks. The shlib-app-1* testsuite changes aren't needed for this patch. I started making them when trying to remove is_relocatable_executable completely, but figure it is worth keeping the more permissive address matching for some future generic linker change. The static-app-1* changes also adjust to the fact that an unneeded "c" no longer appears in the dynamic symbol table. bfd/ * elflink.c (bfd_elf_link_record_dynamic_symbol): Don't do anything special for is_relocatable_executable.
