Fix PR ld/22263 on SPARC. This is -fpie -pie generating dynamic relocations in the text section, simply because no TLS transitions are applied in PIE mode.

Fix compile time warnings building the binutils with clang. bfdI would like to fix instances of the following warning, when building with clang with no special CFLAGS other than -g3 -O0. /home/emaisin/src/binutils-gdb/bfd/elflink.c:5425:45: error: performing pointer arithmetic on a null pointer has undefined behavior [-Werror,-Wnull-pointer-arithmetic] return (struct elf_link_hash_entry *) 0 - 1; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ Replacing those with "(struct elf_link_hash_entry *) -1" gets rid of the warning. I wanted to check that it didn't change the resulting code, so I tried to build this: $ cat test.c int *before() { return (int *) 0 - 1; } int *after() { return (int *) - 1; } $ gcc -c test.c -g $ objdump -d test.o test.o: file format elf64-x86-64 Disassembly of section .text: 0000000000000000 <before>: 0: 55 push %rbp 1: 48 89 e5 mov %rsp,%rbp 4: 48 c7 c0 fc ff ff ff mov $0xfffffffffffffffc,%rax b: 5d pop %rbp c: c3 retq 000000000000000d <after>: d: 55 push %rbp e: 48 89 e5 mov %rsp,%rbp 11: 48 c7 c0 ff ff ff ff mov $0xffffffffffffffff,%rax 18: 5d pop %rbp 19: c3 retq This shows that the previous code doesn't actually return -1 as the function documentation says, but the new one does, so it's kind of a bugfix. bfd * elf64-ppc.c (ppc64_elf_archive_symbol_lookup): Avoid pointer arithmetic on NULL pointer. * elflink.c (_bfd_elf_archive_symbol_lookup, elf_link_add_archive_symbols): Likewise. ld * ldexp.c (fold_name, exp_fold_tree_1): Avoid pointer arithmetic on NULL pointer.

Keep the original empty action with `pr22649-2c.so' and `pr22649-2d.so' links and MIPS/ELF targets though, because for them the linker does not garbage-collect the `.reginfo' section. This is because the section has its flags set differently by code in GAS in `md_begin': if (strncmp (TARGET_OS, "elf", 3) != 0) flags |= SEC_ALLOC | SEC_LOAD; and consequently BFD linker code in `_bfd_elf_gc_mark_extra_sections': else if (((isec->flags & SEC_DEBUGGING) != 0 || (isec->flags & (SEC_ALLOC | SEC_LOAD | SEC_RELOC)) == 0) && elf_next_in_group (isec) == NULL) isec->gc_mark = 1; marks these sections to be kept due to their SEC_ALLOC, SEC_LOAD and SEC_RELOC flags all being zero (`.reginfo' sections never have relocations attached). ld/ PR ld/22649 * testsuite/ld-elf/pr22649-2ab-mips.msg: New stderr output. * testsuite/ld-elf/pr22649-2cd-mips.msg: New stderr output. * testsuite/ld-elf/shared.exp: Use the new outputs with `mips*-*-*' targets.

Fix PR ld/22727 (TLS breakage in PIC/PIE mode on SPARC). There are actually 2 different bugs: 1. TLS transition is broken in PIE mode. 2. TLS is broken in PIC/PIE mode when the __tls_get_addr symbol is versioned (as is the case on Linux and Solaris at least). The 1st bug is fixed by reverting the problematic change for now (note that the associated test doesn't pass on SPARC because of another issue so there is no formal regression in the testsuite). The 2nd bug is fixed by changing the call to _bfd_generic_link_add_one_symbol on __tls_get_addr into a mere lookup in _bfd_sparc_elf_check_relocs. bfd/ * elfxx-sparc.c (_bfd_sparc_elf_check_relocs) <R_SPARC_TLS_GD_CALL>: Do a mere lookup of the __tls_get_addr symbol instead of adding it.

PowerPC PLT stub tidy This is in preparation for the next patch adding Spectre variant 2 mitigation for PowerPC and PowerPC64. Besides tidying code involved in stub output (to reduce the number of places where bctr is output), the patch adds some user visible features: 1) PowerPC64 ELFv2 global entry stubs now are aligned under the control of --plt-align, with a default alignment of 32 bytes. 2) PowerPC64 __glink_PLTresolve is no longer padded out with nops. 3) PowerPC32 PLT stubs are aligned under the control of --plt-align, with the default alignment being 16 bytes as before. 4) The PowerPC32 branch/nop table emitted before __glink_PLTresolve is now smaller in many cases. It was sized incorrectly when the __tls_get_addr_opt stub was used, and unnecessarily included space for local ifuncs. bfd/ * elf32-ppc.c (GLINK_ENTRY_SIZE): Add parameters, handle __tls_get_addr_opt, and alignment sizing.

ld: Fix issue where PROVIDE overrides defined symbol In a linker script, a sequence like this: foo = ADDR (.some_section); bar = foo; PROVIDE (foo = 0); will result in 'bar = ADDR (.some_section)' and 'foo = 0', which seems like incorrect behaviour, foo is clearly defined elsewhere, and so the PROVIDE should not trigger. The problem is that an expression like this: foo = ADDR (.some_section); can't be evaluated until a late phase of the linker, due to the need for the section '.some_section' to have been placed, then the PROVIDE was being marked as being used during an earlier phase. At the end of the link, both lines: foo = ADDR (.some_section); PROVIDE (foo = 0); are active, and this causes the final value of 'foo' to be 0. The solution proposed in this commit is that, during earlier phases of the linker, when we see the expression 'foo = ADDR (.some_section);', instead of ignoring the expression, we create a "fake" definition of 'foo'. The existence of this "fake" definition prevents the PROVIDE from being marked used, and during the final phase the real definition of 'foo' will replace the "fake" definition. The new test provide-6 covers the exact case described above. The provide-7 test is similar to the above, but using constant expressions, this was never broken, but is added here to increase coverage. The provide-8 case also didn't fail before this commit, but I did manage to break this case during development of this patch. This case was only covered by a mmix test before, so I've added this here to increase coverage. ld/ChangeLog: * ldexp.c (exp_fold_tree_1): Rework condition underwhich provide nodes are ignored in the tree walk, and move the location at which we change provide nodes into provided nodes.
