This is a followup to git commit 97196564 "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). For example, the following from libstdc++.so: Symbol table '.dynsym' contains 6090 entries: Num: Value Size Type Bind Vis Ndx Name 0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000000a74e0 0 SECTION LOCAL DEFAULT 10 2: 0000000000264180 0 SECTION LOCAL DEFAULT 17 3: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_addUserCommitAction 4: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_memcpyRtWn 5: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 5 found at index >= .dynsym's sh_info value of 3 6: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 6 found at index >= .dynsym's sh_info value of 3 [snip] This patch removes the symbols from .dynsym too.

This adds the missing Em16 constraints the rest of the instructions requiring them and also adds a testcase to test all the instructions so these are checked from now on.

.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. Set ATTR_TYPE_HAS_ERROR on finding incompatible attribute. (ppc_elf_merge_obj_attributes): Likewise. Return _bfd_elf_merge_object_attributes result. * elf64-ppc.c (ppc64_elf_merge_private_bfd_data): Return _bfd_elf_merge_object_attributes result. (cherry picked from commit 8d2c8c3d)
