* Implement LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [PR109128]Joseph Myers2023-05-111-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is one part of the fix for PR109128, along with a corresponding binutils's linker change. Without this patch, what happens in the linker, when an unused object in a .a file has offload data, is that elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p, which ends up calling the plugin's claim_file_handler, which then records the object as one with offload data. That is, the linker never decides to use the object in the first place, but use of this _p interface (called as part of trying to decide whether to use the object) results in the plugin deciding to use its offload data (and a consequent mismatch in the offload data present at runtime). The new hook allows the linker plugin to distinguish calls to claim_file_handler that know the object is being used by the linker (from ldmain.c:add_archive_element), from calls that don't know it's being used by the linker (from elf_link_is_defined_archive_symbol); in the latter case, the plugin should avoid recording the object as one with offload data.

* Revert "configure: Implement --enable-host-bind-now"Marek Polacek2022-11-222-29/+2
| | | | This reverts commit 258d7149f92f19380c9f7763618d62408c064e60.
* configure: Implement --enable-host-bind-nowMarek Polacek2022-11-222-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As promised in the --enable-host-pie patch, this patch adds another configure option, --enable-host-bind-now, which adds -z now when linking the compiler executables in order to extend hardening. BIND_NOW with RELRO allows the GOT to be marked RO; this prevents GOT modification attacks. This option does not affect linking of target libraries; you can use LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW. c++tools/ChangeLog: * configure.ac (--enable-host-bind-now): New check. * configure: Regenerate. gcc/ChangeLog: * configure.ac (--enable-host-bind-now): New check. Add -Wl,-z,now to LD_PICFLAG if --enable-host-bind-now. * configure: Regenerate. * doc/install.texi: Document --enable-host-bind-now. lto-plugin/ChangeLog: * configure.ac (--enable-host-bind-now): New check.

* Generic configury support for shared libs on VxWorksOlivier Hainque2022-10-111-0/+24

Set lt_cv_deplibs_check_method in libtool.m4, so the build of libraries know how to establish dependencies. This is useful in configurations such as aarch64 where proper support of LSE relies on accurate dependency information between libstdc++ and libgcc_s to begin with.

* lto-plugin: Use GNU ld or Solaris ld version script in preference to ↵Jakub Jelinek2022-03-225-8/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -export-symbols-regex [PR102426] As reported, libtool -export-symbols-regex doesn't work on Solaris when using GNU ld instead of Sun ld, libtool just always assumes Sun ld. As I'm unsure what is the maintainance status of libtool right now, this patch solves it on the lto-plugin side instead, tests at configure time similar way how libssp and other target libraries test for symbol versioning (except omitting the symbol version because we just want one GLOBAL symbol and rest of them LOCAL), and will use the current way of -export-symbols-regex onload as fallback when this doesn't work. 2022-03-22 Jakub Jelinek <jakub@redhat.com> PR lto/102426 lto-plugin/ * configure.ac (LTO_PLUGIN_USE_SYMVER, LTO_PLUGIN_USE_SYMVER_GNU, LTO_PLUGIN_USE_SYMVER_SUN): New test for symbol versioning support. * Makefile.am (version_arg, version_dep): Set conditionally based on LTO_PLUGIN_USE_SYMVER*.

* add -ltrans-objects lto-plugin debug optionRichard Biener2021-06-251-0/+12
| | | | | | | | | | | | | | | | | | | | | | | This adds a -ltrans-objects option to lto-plugin that by-passes lto-wrapper invocation and instead feeds LD the final LTRANS objects directly from the response file given as argument to the option. This allows LD issues involving the linker-plugin path to be debugged in an easier way with just the IR objects (their symtab) and the LTRANS objects as testcase. I've tested the path re-building stage2 build/genmatch from an LTO bootstrap and got a bit-identical executable by adding -plugin-opt=-ltrans-objects=y to the original collect2 invocation, seeding y with the final objects as printed by building genmatch with -save-temps -v. 2021-06-22 Richard Biener <rguenther@suse.de> lto-plugin/ * lto-plugin.c (ltrans_objects): New global.
