Alan Modra	1657026ccd	PowerPC64 DT_RELR PowerPC64 takes a more traditional approach to DT_RELR than x86. Count relative relocs in check_relocs, allocate space for them and output in the usual places but not doing so when enable_dt_relr. DT_RELR is sized in the existing ppc stub relaxation machinery, run via the linker's ldemul_after_allocation hook. DT_RELR is output in the same function that writes ppc stubs, run via ldemul_finish. This support should be considered experimental. bfd/ * elf64-ppc.c (struct ppc_local_dyn_relocs): Renamed from ppc_dyn_relocs. Add rel_count field. Update uses. (struct ppc_dyn_relocs): New.

Clément Chigot	3c5038247c	XCOFF: add support for TLS relocations on hidden symbols This patch adds support for TLS relocation targeting C_HIDEXT symbols.

H.J. Lu	3747999c6b	ld: Extract _bfd_elf_link_iterate_on_relocs DT_RELR encodes consecutive R__RELATIVE relocations in GOT (the global offset table) and data sections in a compact format: https://groups.google.com/g/generic-abi/c/bX460iggiKg On some targets, R__RELATIVE relocations are counted and the GOT offsets are allocated when setting the dynamic section sizes after seeing all relocations. R__RELATIVE relocations are generated while relocating sections after section layout has been finalized. To prepare for DT_RELR implementation on these targets, extract _bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so that a backend can scan relocations in elf_backend_always_size_sections For x86 targets, the old check_relocs is renamed to scan_relocs and a new check_relocs is added to chek input sections and create dynamic relocation sections so that they will be mapped to output sections. scan_relocs is now called from elf_backend_always_size_sections. Since relocations are scanned after __start, __stop, .startof. and .sizeof. symbols have been finalized on x86, __[start\|stop]_SECNAME for --gc-sections -z start-stop-gc are now zero when all SECNAME sections been garbage collected.

H.J. Lu	74e315dbfe	elf: Set p_align to the minimum page size if possible Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align values of 0x10000 even if no section alignment is greater than 0x1000. The issue is more general and probably affects other targets with multiple page sizes. While file layout absolutely must take 64K page size into account, that does not have to be reflected in the p_align value. If running on a 64K kernel, the file will be loaded at a 64K page boundary by necessity. On a 4K kernel, 64K alignment is not needed. The glibc loader has been fixed to honor p_align: https://sourceware.org/bugzilla/show_bug.cgi?id=28676 similar to kernel: commit ce81bb256a224259ab686742a6284930cbe4f1fa Author: Chris Kennelly <ckennelly@google.com> Date: Thu Oct 15 20:12:32 2020 -0700 fs/binfmt_elf: use PT_LOAD p_align values for suitable start address This means that on 4K kernels, we will start to do extra work for 64K p_align, but this pointless for pretty much all binaries (whose section alignment rarely exceeds 16). The minimum page size is used, instead of the maximum section alignment due to this glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28688 It has been fixed in glibc 2.35. But linker output must work on existing glibc binaries. 1. Set p_align to the minimum page size while laying out segments aligning to the maximum page size or section alignment. The run-time loader can align segments to the minimum page size or above, depending on system page size. 2. If -z max-page-size=NNN is used, p_align will be set to the maximum page size or the largest section alignment. 3. If a section requires alignment higher than the minimum page size, don't set p_align to the minimum page size. 4. If a section requires alignment higher than the maximum page size, set p_align to the section alignment. 5. For objcopy, when the minimum page size != the maximum page size, p_align may be set to the minimum page size while segments are aligned to the maximum page size. In this case, the input p_align will be ignored and the maximum page size will be used to align the ouput segments. 6. Update linker to disallow the common page size > the maximum page size. 7. Update linker to avoid the common page size > the maximum page size. 8.
