* Gentoo: opcodes: link against libbfd.la for rpath depsMike Frysinger2018-07-152-2/+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 Frysinger2018-07-151-0/+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 Frysinger2018-07-1511-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a followup to git commit 97196564c7 "Strip global symbol defined in discarded section". If a symbol defined in a discarded section was dynamic, that patch left .dynsym with holes (ie. all zero entries).

* GNU attribute output on errorsAlan Modra2018-07-055-58/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .gnu.attributes entries from linker input files are merged to the output file, the output having the union of compatible input attributes. Incompatible attributes generally cause a linker error and no output. However in some cases only a warning is emitted, and one of the incompatible input attributes is passed on to the output. PowerPC tends to emit warnings rather than errors, and the output takes the first input attribute. For example, if we have two input files with Tag_GNU_Power_ABI_FP, the first with a value signifying "double-precision hard float, IBM long double", the second with a value signifying "double-precision hard float, IEEE long double", we'll get a warning about incompatible long double types and the output will say "double-precision hard float, IBM long double". The output attribute of course isn't correct. It would be correct to specify "IBM and IEEE long double", but we don't have a way to represent that currently. While it would be possible to extend the encoding, there isn't much gain in doing so. A shared library providing support for both long double types should link against objects using either long double type without warning or error. That is what you'd get if such a shared library had no Tag_GNU_Power_ABI_FP attribute. So this patch provides a way for the backend to omit .gnu.attributes tags from the output. * elf-bfd.h (ATTR_TYPE_FLAG_ERROR, ATTR_TYPE_HAS_ERROR): Define. * elf-attrs.c (is_default_attr): Handle ATTR_TYPE_HAS_ERROR. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): Use ATTR_TYPE_FLAG_INT_VAL.
