* Gentoo: ld: enable new dtags by default for linux/gnu targetsAndreas K. Hüttel2021-01-241-0/+10
| | | | | | | | | | | | | | | | | | Original author: Mike Frysinger <vapier@gentoo.org> The "new" dtags options have been around for 14+ years now, so for Linux and GNU targets, enable them by default. 2012-01-21 Mike Frysinger <vapier@gentoo.org> * emultempl/elf32.em (gld${EMULATION_NAME}_before_parse): Set link_info.new_dtags to TRUE for linux/gnu targets. * NEWS: Mention new dtags default. 2013-01-22 Roland McGrath <mcgrathr@google.com> * emultempl/elf32.em (gld${EMULATION_NAME}_before_parse): Set new_dtags to TRUE for *-*-nacl* targets.
* Gentoo: add --with-extra-soversion-suffix= optionSergei Trofimovich2021-01-244-0/+29
| | | | | | | | | | | | | | | | | | | | | --with-extra-soversion-suffix= will allow Gentoo to distinct libbfd.so and libopcodes.so to have more precise SONAME. Today --enable-targets=all and --enable-64-bit-bfd change libbfd.so ABI: --enable-targets=all adds new symbols to the library --enable-64-bit-bfd modifies BFD_ARCH_SIZE default and changes sizes of integer parameters and fields to most APIs. --with-extra-soversion-suffix= will allow Gentoo to inject additional keys into SONAME to indicate ABI change and avoid hard to diagnose crashes when user reinstalls libbfd.so built with different flags (see https://bugs.gentoo.org/663690). Bug: https://bugs.gentoo.org/666100 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* Gentoo: opcodes: link against libbfd.la for rpath depsMike Frysinger2021-01-242-2/+2
| | | | | | | | | | | | | The reason opcodes doesn't link against libbfd.la is to workaround a libtool bug where it uses installed -L paths ahead of DESTDIR paths. The downside is that the library itself lacks rpath tags to find the right version of libbfd.so. Since Gentoo has patched the libtool bug for a while, we don't need the workaround. Use the .la file so we get the rpath tags. URL: https://bugs.gentoo.org/563934 (cherry picked from commit 662586237b0b00ee881e79b56f6234ff36e8bfe6)
* Gentoo: libiberty: install PIC version of libiberty.aMike Frysinger2021-01-241-0/+1
| | | | | | | | | | | | | This will install a PIC version of libiberty.a by overwriting the non-PIC version of libiberty.a while compiling. We do this because there is no shared version of libiberty for random apps to link against which means if someone wants to use this in a shared library or PIE, they're out of luck. It's arguable whether people should be able to use this in a shared lib, but usage in PIE should be fine. You could argue that this penalizes the non-PIE users, but the counter point is that people using this library in general are fairly low, and we'd rather have things work for all of them.

* Gentoo: gold/ld: add support for poisoned system directoriesMike Frysinger2021-01-2411-0/+146
| | | | | | | | | | | | | | | | | | | | | | This is based on the old CodeSourcery patch written by Joseph Myers to add support to the link for detecting & rejecting bad -L paths when using a cross-compiler. The differences here: * The command line flags are always available. * We can turn on & off the warning via the command line. * The configure option controls the default warning behavior. * Add support for gold. It is not currently upstream, nor has it been submitted at all. There are no plans to do so currently either.

* libctf, create: fix ctf_type_add of structs with unnamed membersNick Alcock2021-01-195-0/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our recent commit to support unnamed structure members better ditched the old ctf_member_iter iterator body in favour of ctf_member_next. However, these functions treat unnamed structure members differently: ctf_member_iter just returned whatever the internal representation contained, while ctf_member_next took care to always return "" rather than sometimes returning "" and sometimes NULL depending on whether the dict was dynamic (a product of ctf_create) or not (a product of ctf_open). After this commit, ctf_member_iter did the same. It was always a bug for external callers not to treat a "" return from these functions as if it were NULL, so only buggy callers could be affected -- but one of those buggy callers was ctf_add_type, which assumed that it could just take whatever name was returned from ctf_member_iter and slam it directly into the internal representation of a dynamic dict -- which expects NULL for unnamed members, not "". The net effect of all of this is that taking a struct containing unnamed members and ctf_add_type'ing it into a dynamic dict produced a dict whose unnamed members were inaccessible to ctf_member_info (though if you wrote that dict out and then ctf_open'ed it, they would magically reappear again). Compensate for this by suitably transforming a "" name into NULL in the internal representation, as should have been done all along. libctf/ChangeLog 2021-01-19 Nick Alcock <nick.alcock@oracle.com> * ctf-create.c (membadd): Transform ""-named members into NULL-named ones. * testsuite/libctf-regression/type-add-unnamed-struct*: New test.

* libctf: lookup_by_name: do not return success for nonexistent pointer typesNick Alcock2021-01-195-10/+45
| | | | | | | | | | | | | | | | | | | The recent work allowing lookups of pointers in child dicts when the pointed-to type is in the parent dict broke the case where a pointer type that does not exist at all is looked up: we mistakenly return the pointed-to type, which is likely not a pointer at all. This causes considerable confusion. Fixed, with a new testcase. libctf/ChangeLog 2021-01-19 Nick Alcock <nick.alcock@oracle.com> * ctf-lookup.c (ctf_lookup_by_name_internal): Do not return the base type if looking up a nonexistent pointer type. * testsuite/libctf-regression/pptrtab*: Test it.

* ld: Just xfail riscv little endian targets for compressed1d.d test.Nelson Chu2021-01-193-2/+23
| | | | | | | | | | | | | | | | | The sizes of compressed and uncompressed .debug_aranges are the same for the riscv big endian targets, but different for the little endian targets. The compress rule is fine and isn't broken by riscv, just the original compressed1d.d fails by accident. Ideally, we should fill the R_RISCV_ADD/SUB relocations when disabling relaxations in the assembler. But before that, Jim already had written an alternative test compressed1d-alt to relpace compressed1d.d for riscv, so we can only xfail the riscv little endian targets in the short-term. ld/ * testsuite/ld-elf/elf.exp (riscv_little_endian): Added. Return true if target is riscv little endian. Otherwise, return false. * testsuite/ld-elf/compressed1d.d: Only xfail the riscv little endian targets by [riscv_little_endian].
