2022-02-08RISC-V: Stop reporting warnings for mismatched extension versionsPalmer Dabbelt1-54/+24
The extension version checking logic is really just too complicated to encode into the linker, trying to do so causes more harm than good. This removes the checks and the associated tests, leaving the logic to keep the largest version of each extension linked into the target. bfd/ * elfnn-riscv.c (riscv_version_mismatch): Rename to riscv_update_subset_version, and stop reporting warnings on version mismatches.

2022-02-03PowerPC64 treatment of absolute symbolsAlan Modra1-62/+126
Supporting -static-pie on PowerPC64 requires the linker to properly treat SHN_ABS symbols for cases like glibc's _nl_current_LC_CTYPE_used absolute symbol.

2022-02-02or1k: Avoid R_OR1K_GOT16 signed overflow by using special howtoStafford Horne2-4/+27
Previously when fixing PR 21464 we masked out upper bits of the relocation value in order to avoid overflow complaints when acceptable. It turns out this does not work when the relocation value ends up being signed. To fix this this patch introduces a special howto with complain_on_overflow set to complain_overflow_dont. This is used in place of the normal R_OR1K_GOT16 howto when we detect R_OR1K_GOT_AHI16 relocations. bfd/ChangeLog: PR 28735 * elf32-or1k.c (or1k_elf_got16_no_overflow_howto): Define.

2022-01-29Re: PR28827, assertion building LLVM 9 on powerpc64le-linux-gnuAlan Modra1-11/+10
The previous patch wasn't quite correct. The size and padding depends on offset used in the current iteration, and if we're fudging the offset past STUB_SHRINK_ITER then we'd better use that offset. We can't have plt_stub_pad using stub_sec->size as the offset. PR 28827 * elf64-ppc.c (plt_stub_pad): Add stub_off param. (ppc_size_one_stub): Set up stub_offset to value used in this iteration before sizing the stub. Adjust plt_stub_pad calls.

2022-01-28PR28827, assertion building LLVM 9 on powerpc64le-linux-gnuAlan Modra1-23/+36
The assertion is this one in ppc_build_one_stub BFD_ASSERT (stub_entry->stub_offset >= stub_entry->group->stub_sec->size); It is checking that a stub doesn't overwrite the tail of a previous stub, so not something trivial. Normally, stub sizing iterates until no stubs are added, detected by no change in stub section size. Iteration also continues if no stubs are added but one or more stubs increases in size, which also can be detected by a change in stub section size. But there is a pathological case where stub section sizing decreases one iteration then increases the next. To handle that situation, stub sizing also stops at more than STUB_SHRINK_ITER (20) iterations when calculated stub section size is smaller. The previous larger size is kept for the actual layout (so that building the stubs, which behaves like another iteration of stub sizing, will see the stub section sizes shrink). The problem with that stopping condition is that it assumes that stub sizing is only affected by addresses external to the stub sections, which isn't always true. This patch fixes that by also keeping larger individual stub_offset addresses past STUB_SHRINK_ITER. It also catches a further pathological case where one stub shrinks and another expands in such a way that no stub section size change is seen. PR 28827 * elf64-ppc.c (struct ppc_link_hash_table): Add stub_changed. (STUB_SHRINK_ITER): Move earlier in file. (ppc_size_one_stub): Detect any change in stub_offset. Keep larger one if past STUB_SHRINK_ITER. (ppc64_elf_size_stubs): Iterate on stub_changed too.
