S/390: Fix gotreloc_31-1 testcase. Since we changed the default arch for objdump to zarch the following testcase needs to check for the real instruction mnemonics instead of just bytes. This fixes the following testsuite fail on s390x: FAIL: GOT: symbol address load from got to larl

Non-alloc sections don't belong in PT_LOAD segments Taking them out showed a bug in the powerpc64 backend with .branch_lt being removed from output_bfd but not from previously set up segment section maps. Removing the bfd sections meant their sh_flags (and practically everything else) remaining zero, ie. not SHF_ALLOC, triggering complaints about "`.branch_lt' can't be allocated in segment". include/elf/ * internal.h (ELF_SECTION_IN_SEGMENT_1): Ensure PT_LOAD and similar segments only contain alloc sections. ld/ * emultempl/ppc64elf.em (gld${EMULATION_NAME}_after_allocation): Call gld${EMULATION_NAME}_map_segments regardless of need_laying_out. ld/testsuite/ * ld-powerpc/tocnovar.d: Revert last change.

Delay setting up compressed debug section names When we set up st_name for output section name in elf_fake_sections, we don't know if the compressed DWARF debug section will be smaller. We may end up with compressed DWARF debug sections which are bigger than the uncompressed ones. This patch delays setting up st_name for output DWARF debug section to _bfd_elf_assign_file_positions_for_non_load which will compress the output debug section. We also postpone placement of shstrtab section after DWARF debug sections have been compressed. The net effect is .shstrtab section is now placed after .symtab and .strtab sections. bfd/ PR ld/18277 * compress.c (bfd_compress_section_contents): Remove the write_compress argument.

Accept odd result in ld-powerpc/tocnovar testcase I didn't commit this with the relro and powerpc .TOC. changes, thinking that something should be done about the odd result of .shstrtab appearing in PT_GNU_RELRO.

Rewrite relro adjusting code The linker tries to put the end of the last section in the relro segment exactly on a page boundary, because the relro segment itself must end on a page boundary. If for any reason this can't be done, padding is inserted. Since the end of the relro segment is typically between .got and .got.plt, padding effectively increases the size of the GOT. This isn't nice for targets and code models with limited GOT addressing. The problem with the current code is that it doesn't cope very well with aligned sections in the relro segment. When making .got aligned to a 256 byte boundary for PowerPC64, I found that often the initial alignment attempt failed and the fallback attempt to be less than adequate. This is a particular problem for PowerPC64 since the distance between .got and .plt affects the size of plt call stubs, leading to "stubs don't match calculated size" errors. So this rewrite takes a direct approach to calculating a new relro base. Starting from the last section in the segment, we calculate where it must start to position its end on the boundary, or as near as possible considering alignment requirements. The new start then becomes the goal for the previous section to end, and so on for all sections. This of course ignores the possibility that user scripts will place . = ALIGN(xxx); in the relro segment, or provide section address expressions. In those cases we might fail, but the old code probably did too, and a fallback is provided. ld/ * ldexp.h (struct ldexp_control): Delete dataseg.min_base.

Add -z noextern-protected-data to ld for ELF/x86 Address of protected data defined in the shared library may be external, i.e., due to copy relocation. By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library.

[AArch64] Workaround for Cortex A53 erratum 843419 Some early revisions of the Cortex-A53 have an erratum (843419). The details of the erratum are quite complex and involve dynamic conditions. For the purposes of the workaround we have simplified the static conditions to an ADRP in the last two instructions of a 4KByte page, followed within four instructions by a load/store dependent on the ADRP. This patch adds support to conservatively scan for and workaround Cortex A53 erratum 843419. There are two different workaround strategies used. The first is to rewrite ADRP instructions which form part of an erratum sequence with an ADR instruction. In situations where the ADR provides insufficient offset the dependent load or store instruction from the sequence is moved to a stub section and branches are inserted from the original sequence to the relocated instruction and back again. Stub section sizes are rounded up to a multiple of 4096 in order to ensure that the act of inserting work around stubs does not create more errata sequences. Workaround stubs are always inserted into the stub section associated with the input section containing the erratum sequence. This ensures that the fully relocated form of the veneered load store instruction is available at the point in time when the stub section is written.

[AArch64] Implement branch over stub section. Ensure that injection of a stub section does not break a link where there is an xpectation that flow of control can pass from one input section to another simply by linking the input sections in series. The solution here is to allow stub sections to be inserted after any input section (existing behaviour), but inject an additional branch at the start of each stub section such that control flow falling into the stub section will branch over the stub section.

Properly place the NULL STT_FILE symbol revistited I was having a little closer look at what is going on here and noticed that HJ unconditionally emits a NULL STT_FILE symbol before emitting forced local symbols. That means we really don't need a second pass over forced local symbols. The only reason for two passes is when some forced local symbol can be emitted before the NULL STT_FILE. So I set about removing the second pass, updating the testsuite all over again. It's also unnecessary to emit the NULL STT_FILE when no previous file symbol has been emitted. bfd/ PR ld/17975 * elflink.c (struct elf_outext_info): Remove need_second_pass and second_pass. (elf_link_output_extsym): Delete code handling second forced local pass. Move code emitting NULL STT_FILE symbol later, so that it can be omitted if forced local is stripped.

Correct PowerPC64 local-dynamic TLS linker optimization The linker hardcoded r3 into a local-dynamic to local-exec TLS optimization sequence. This is normally the case since r3 is required as a parameter to (the optimized out) __tls_get_addr call. However, it is possible for a compiler, LLVM in this case, to set up the parameter value in another register then copy it to r3 before the call. When fixing this problem, I noticed that ppc32 had another bug when optimizing away one of the TLS insns to a nop. The patch also tidies a mask used by global-dynamic to initial-exec TLS optimization, to just select the fields needed. Leaving the offset in the instruction wasn't a bug since it will be overwritten anyway. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Correct GOT_TLSLD optimization.

PowerPC64 changes for xlc The changes to reorder sections for better relro protection on powerpc64, 3e2b0f31, 23283c1b, and 5ad18f16, run into a problem with xlc. xlc -qdatalocal puts global variables into .toc, which means that .toc must be writable.

Allow symbols in MEMORY region specification This patch fixes PR 4643 by allowing symbols in the LENGTH and ORIGIN fields of MEMORY regions.

ld: Don't evaluate unneeded PROVIDE expressions. When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined. Display a special message for PROVIDE'd symbols that are not being provided. ld/testsuite/ChangeLog: * ld-scripts/provide-4.d: New file. * ld-scripts/provide-4-map.d: New file. * ld-scripts/provide-4.t: New file. * ld-scripts/provide-5.d: New file. * ld-scripts/provide-5.s: New file. * ld-scripts/provide-5-map.d: New file. * ld-scripts/provide-5.t: New file. * ld-scripts/provide.exp: Run the provide-4.d and provide-5.d tests.

ld/testing: run_dump_test can now check linker mapfiles. Add a new option 'map' to the ld run_dump_test mechanism. When the 'map' option is given run_dump_test will ensure that there is a -Map=MAPFILE present in the linker command line, adding one if needed. The MAPFILE is then compared with the file passed to the new 'map' option using the regexp_diff function. This should make it slightly easier to write tests that check the linker mapfile output. The only test I found that already compares mapfile content is updated to use the new mechanism. ld/testsuite/ChangeLog: * ld-scripts/overlay-size.d: Add 'map' option. * ld-scripts/overlay-size.exp: Remove manual check of mapfile. * lib/ld-lib.exp (run_dump_test): Add support for new 'map' option, checking linker mapfile output.

Reorder more powerpc64 sections for -z relro This moves .got too, which requires .sdata and .sbss to move with it, because these sections share addressing via the toc pointer and with small-model code must be within a 16-bit signed offset. .plt, .iplt and .branch_lt must also be moved since they are addressed via a 32-bit offset from the toc pointer, and we might have a very large .data section. This change means we may have some bss style sections before the data segment, necessitating another PT_LOAD header. Also, since _edata is defined at the end of the data segment it's possible with an empty .data to have _edata at the end of .plt which looks a little unusual since .plt is a bss style section. That should only happen rarely in real world binaries, but does occur in the ld testsuite. ld/ * emulparams/elf64ppc.sh (BSS_PLT): Don't define. (OTHER_READWRITE_SECTIONS): Move .branch_lt to..
