The attempt in 5e9091dab885 to correct gold for modern LLVM has broken gold for older compilers. This commit introduced C++11 types without changing the build system to require a C++ compiler. More importantly it depends on the compiler having at least C++11 as the default language. Older compilers which support C++11 but not as the default language needlessly break. Fix that.

2023-12-11R_MICROMIPS_GPREL7_S2Alan Modra1-18/+64
This reloc is meant for the 16-bit LWGP instruction, 0x6400/0xfc00 match/mask encoding in `micromips_opcodes'. It is correctly specified to operate on a half-word by the howtos in elf32-mips.c, elfn32-mips.c and elf64-mips.c, but is incorrectly subject to shuffle/unshuffle in code like _bfd_mips_elf32_gprel16_reloc. Current behaviour when applying the reloc to .byte 0x11,0x22,0x33,0x44 is to apply the reloc to byte 0x22 when big-endian, and to byte 0x33 when little-endian. Big-endian behaviour is unchanged after this patch and little-endian correctly applies the reloc to byte 0x11. The patch also corrects REL addend extraction from section contents, and overflow checking. gold had all of the bfd problems with this reloc and additionally did not apply the rightshift by two. bfd/ * elfxx-mips.c (micromips_reloc_shuffle_p): Return false for R_MICROMIPS_GPREL7_S2.

The std::basic_string template type is only specified for instantiations using character types. Newer (LLVM) libc++ implementations no longer allow non-character integer types to be used. gold/ * output.cc: Include <uchar.h>. (Output_section::add_merge_input_section): Use char16_t and char32_t for 2- and 4-byte entry size, respectively. * stringpool.cc: Include <uchar.h>. (Stringpool_template): Explicitly instantiate for char16_t, char32_t instead of uint16_t, uint32_t. * merge.cc (Output_merge_string): Likewise.

2023-08-27MIPS: Use 64-bit a ABI by default for `mipsisa64*-*-linux*' targetsYunQiang Su1-2/+2
Following the arrangement in GCC select a 64-bit ABI by default, either n32 or n64, rather than o32 for `mipsisa64*-*-linux*' targets, just as with the corresponding `mips64*-*-linux*' targets.
2023-08-27Gold/MIPS: Add mips64*/mips64*el triple supportYunQiang Su1-0/+16
Use targ_size=64 and targ_extra_size=32
2023-08-27Gold/MIPS: Add targ_extra_size=64 for mips32 triplesYunQiang Su1-0/+2
So we can enable 64bit ELF support for MIPS32 toolchain.
2023-08-27Gold/MIPS: Drop mips*le/mips*el* triple patternYunQiang Su1-1/+1
Only mips*el triples are supported by binutils. The mips*le or mips*el* may cause some problem with other components of binutils, since they will consider them as big endian.
2023-08-27Gold/MIPS: Use EM_MIPS instead of EM_MIPS_RS3_LE for little endianYunQiang Su1-1/+1
EM_MIPS_RS3_LE has been deprecated quite long ago, and in fact most of current LE ELF files are using EM_MIPS. This problem didn't make some trouble for us, is due to that gold is a linker, and all of the inputs to it has right EM values.
2023-08-27Gold: Add targ_extra_little_endian to configure.acYunQiang Su3-1/+17
This option will be used by architectures which is big endian by default, while little-endian support is also needed. Mips(eb) ports are the examples.
2023-08-25PR30794, PowerPC gold: internal error in add_output_section_to_loadAlan Modra1-22/+25
Caused by commit 5a97377e5513, specifically this code added to Target_powerpc::do_relax + if (parameters->options().output_is_position_independent()) + this->rela_dyn_size_ + = this->rela_dyn_section(layout)->current_data_size(); The problem here is that if .rela.dyn isn't already created then the call to rela_dyn_section creates it, and as this comment in Target_powerpc::do_finalize_sections says: // Annoyingly, we need to make these sections now whether or // not we need them. If we delay until do_relax then we // need to mess with the relaxation machinery checkpointing. We can't be creating sections in do_relax. PR 30794 * powerpc.cc (Target_powerpc::do_relax): Only set rela_dyn_size_ for size == 64, and assert that rela_dyn_ already exists. Tidy code setting plt_thread_safe, which also only needs to be set when size == 64 for ELFv1.

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.
