* MIPS: support mips*64 as CPU and gnuabi64 as ABIYunQiang Su2023-04-231-0/+14
| | | | | | | | | | 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.

* PR30217, dynamic relocations using local dynamic symbolsAlan Modra2023-03-161-24/+39
| | | | | | | | | | | | | | | | | | | | | glibc's ld.so ignores local dynamic symbols. It's been that way forever. We therefore can't use them on dynamic relocations. Fixing that problem uncovered another problem in sorting of dynamic relocs, caused no doubt by copying make_iplt_section (where we don't want reloc sorting by the generic gold function, we want iplt relocs last) to make_lplt_section (where we do want sorting). PR 30217 * powerpc.cc (branch_needs_plt_entry): New function. (Target_powerpc::plt_off): Use it here.. (Target_powerpc::Scan::global): ..and here to correct PLT16 reloc handling for forced-local global symbols. (Output_data_plt_powerpc::add_entry): Rename "stash" parameter "is_local".

* gold: Suppress "unused" variable warning on ClangTsukasa OI2022-09-271-0/+3
| | | | | | | | | | | | | | | Clang generates a warning if there is a variable that is set but not used otherwise ("-Wunused-but-set-variable"). On the default configuration, it causes a build failure (unless "--disable-werror" is specified). Because the cause of this error is in the Bison-generated code ($(srcdir)/gold/yyscript.y -> $(builddir)/gold/yyscript.c), this commit suppresses this warning ("-Wunused-but-set-variable") by placing DIAGNOSTIC_IGNORE_UNUSED_BUT_SET_VARIABLE macro at the end of user prologue on yyscript.y. * yyscript.y: Suppress -Wunused-but-set-variable warning on the Bison-generated code.

* bfd: Stop using -Wstack-usage=262144 when built with ClangTsukasa OI2022-09-141-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some components of GNU Binutils will pass "-Wstack-usage=262144" when "GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage", despite that related configuration part in bfd/warning.m4 handles the latest Clang (15.0.0 as of this writing) as "GCC >= 5.0". The option "-Wstack-usage" was ignored when the first version of Clang is released but even this "ignoring" behavior is removed before Clang 4.0.0. So, if we give Clang "-Wstack-usage=262144", it generates a warning, making the build failure. This commit checks "__clang__" macro to prevent adding the option if the compiler is identified as Clang. bfd/ChangeLog: * warning.m4: Stop appending "-Wstack-usage=262144" option when compiled with Clang. * configure: Regenerate. binutils/ChangeLog: * configure: Regenerate. gas/ChangeLog: * configure: Regenerate. gold/ChangeLog: * configure: Regenerate. gprof/ChangeLog: * configure: Regenerate. ld/ChangeLog: * configure: Regenerate. opcodes/ChangeLog: * configure: Regenerate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fixes gold failures to handle inline PLT sequences properly. PowerPC gold was always turning these back into direct calls due to gsym->use_plt_offset() returning false. This is fixed for dynamic linking by correcting get_reference_flags, and for static linking by overriding use_plt_offset() in relocate(). The rest of the patch revolves around needing to create PLT entries for inline PLT calls when statically linking (for gcc -mlongcall).

* Re: PR27625, powerpc64 gold __tls_get_addr callsAlan Modra2021-10-211-156/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | My previous PR27625 patch had a problem or two. For one, the error "__tls_get_addr call lacks marker reloc" on processing some calls before hitting a call without markers typically isn't seen. Instead a gold assertion fails. Either way it would be a hard error, which triggers on a file contained in libphobos.a when running the gcc testsuite. A warning isn't even appropriate since the call involved is one built by hand without any of the arg setup relocations that might result in linker optimisation. So this patch reverts most of commit 0af4fcc25dd5, instead entirely ignoring the problem of mis-optimising old-style __tls_get_addr calls without marker relocs. We can't handle them gracefully without another pass over relocations before decisions are made about GOT entries in Scan::global or Scan::local. That seems too costly, just to link object files from 2009. What's more, there doesn't seem to be any way to allow the libphobos explicit __tls_get_addr call, but not old TLS sequences without marker relocs. Examining instructions before the __tls_get_addr call is out of the question: program flow might reach the call via a branch. Putting an R_PPC64_TLSGD marker with zero sym on the call might be a solution, but current linkers will then merrily optimise away the call!

| | | | | | | | | | We can't get at section->address() until everything is laid out, so trying to generalise the offset calculation rather than using a value of 0x8000 (the old object->toc_base_offset()) was bound to fail. got->g_o_t() is a little better than a hard-coded 0x8000. * powerpc.cc (Target_powerpc::Scan::local, global): Don't use toc_pointer() here.

* [GOLD] PowerPC64: Don't pretend to support multi-tocAlan Modra2021-10-141-114/+67
| | | | | | | | | | | | | | | | | | | | | | | | Code in powerpc.cc is pretending to support a per-object toc pointer value, but powerpc gold has no real support for multi-toc. This patch removes the pretense, tidying quite a lot in preparation for a followup patch. If multi-toc is ever to be supported, don't revert this patch but start by adding object parameter to toc_pointer() and an object to Branch_stub_key. * powerpc.cc (Powerpc_relobj::toc_base_offset): Delete. (Target_powerpc::toc_pointer): New function. Use throughout. (Target_powerpc::got_base_offset): New function. Use throughout.. (Output_data_got_powerpc::got_base_offset): ..in place of this. Delete. (Output_data_got_powerpc::Output_data_got_powerpc): Init header_index_ to -1u for 64-bit, and make header here. (Output_data_got_powerpc::set_final_data_size, reserve_ent): Don't make 64-bit header here. (Output_data_got_powerpc::g_o_t): Return toc pointer offset in section for 64-bit. Use throughout. (Stub_table): Remove toc_base_off_ from Branch_stub_key, and object param on add_long_branch_entry and find_long_branch_entry. Adjust all uses.
