2019-06-23PR24704, Internal error building skiboot for powerpc64-linux-gnuAlan Modra2-16/+25
While the skiboot linker script bears some culpability in this PR, it's also true that the GOT indirect to GOT relative optimisation for 16-bit offsets isn't safe. At least, it isn't safe to remove the GOT entry based on distance between the GOT pointer and symbol calculated from the preliminary layout. So this patch removes that optimisation, and reduces the range allowed for 32-bit and 34-bit offsets. PR 24704 bfd/ * elf64-ppc.c (R_PPC64_GOT16_DS): Don't set has_gotrel. (ppc64_elf_edit_toc): Don't remove R_PPC64_GOT16_DS got entries.

2019-06-21PR24689, string table corruptionAlan Modra2-1/+7
The testcase in the PR had a e_shstrndx section of type SHT_GROUP. hdr->contents were initialized by setup_group rather than being read from the file, thus last byte was not zero and string dereference ran off the end of the buffer. PR 24689 * elfcode.h (elf_object_p): Check type of e_shstrndx section.

2019-06-19PowerPC64 notoc callsAlan Modra2-3/+9
Calls from functions that don't have a valid toc pointer in r2 (these calls are marked with _NOTOC relocs) to functions that require r2 valid must go via the callee global entry point. This patch corrects the condition the linker was using to detect functions that require r2 to be valid. Values of both zero and one in st_other local entry bits mean a function doesn't care about r2. * elf64-ppc.c (ppc64_elf_inline_plt): Correct st_other test for functions that require r2 valid to use local entry. (ppc64_elf_size_stubs, ppc64_elf_relocate_section): Likewise.

2019-06-06[BFD, AArch64] Fix PT_GNU_PROPERTY alignment issueSudakshina Das2-0/+13
If the new GNU property section was being created by the linker (this will happen only if none of the inputs have any GNU property section but the command line to the linker forces a bti with --force-bti), the alignment of the section and hence the program header of PT_GNU_PROPERTY type was not being set correctly.
