2018-01-18solaris2.em: Fold after_allocation into before_allocationH.J. Lu2-41/+35
Since all ELF linkers call check_relocs after opening all inputs, we can fold after_allocation into before_allocation so that local dynamic symbols will be placed before global dynamic symbols in .dynsym section. This fixed: FAIL: Common symbol override test (auxiliary shared object build) FAIL: ld-elf/pr19617a FAIL: ld-elf/pr19698 for i386-solaris2.12 and x86_64-solaris2.12 targets.

2018-01-18PowerPC PLT stub alignment fixesAlan Modra3-4/+18
Asking for ppc32 plt call stubs to be aligned at 32 byte boundaries didn't quite work. For ld.bfd they were spaced 32 bytes apart, but only started on a 16 byte boundary. ld.gold also didn't get it right. Finding that bug made me check over the ppc64 plt stub alignment, where I found that negative values for alignment (meaning align to minimize boundary crossing) were not accepted. Since no one has complained about that, I guess I could have removed the feature from ld.bfd documentation, but I've opted instead to correct the code. I've also added an optional alignment paramenter for ppc32 --plt-align, for some consistency with gold and ppc64 ld.bfd. bfd/ * elf32-ppc.c (ppc_elf_create_glink): Correct alignment of .glink. * elf64-ppc.c (ppc64_elf_size_stubs): Handle negative plt_stub_align.

2018-01-17PowerPC PLT stub tidyAlan Modra17-96/+141
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.

2018-01-12Add -z undefs option to the ELF linker.Nick Clifton4-2/+26
Currently we have no obvious way to revert the action of the "-z defs" command line option. The "--unresolved-symbols=ignore-in-object-files" does pretty much what is needed, but it is non-obvious and it also touches the setting for reporting unresolved symbol references from shared libraries. So I am proposing adding a "-z undefs" option to be the inverse of "-z defs". (I thought that "-z nodefs" might be confusing since it implies banning all definitions, rather than allowing them). In addition the description of the "-z defs" option in the linker documentation is misleading in one place, where it says: 'defs' Disallows undefined symbols in object files. Undefined symbols in shared libraries are still allowed. whereas later on it gets it right: '-z defs' Report unresolved symbol references from regular object files. This is done even if the linker is creating a non-symbolic shared library. The switch '--[no-]allow-shlib-undefined' controls the behaviour for reporting unresolved references found in shared libraries being linked in. * emultempl/elf32.em (_handle_option): Add support for "-z undefs" as the opposite of "-z defs". * ld.texinfo: Document the new option. Update the description of the -z defs option to make it clear that it does generate an error if an undefined symbol reference is found in an object file whilst creating a shared library. * NEWS: Document this new feature.

2018-01-11ld: Fix issue where PROVIDE overrides defined symbolAndrew Burgess9-42/+121
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.

2017-12-13[BFD][AARCH64]Disallow R_AARCH64_ABS32(LP64) & R_AARCH64_ABS16 in const ↵Renlin Li7-3/+37
section of shared object. R_AARCH64_ABS64, R_AARCH64_ABS32 and R_AARCH64_ABS16 are data relocations supported in AArch64 elf ABI. R_AARCH64_ABS64 under LP64 is allowed in shared object and a dynamic relocation entry will be generated. This allows the dynamic linker to do further symbol resolution. R_AARCH64_ABS32 likewise is allowed in shared object, however under ILP32 abi. The original behavior for R_AARCH64_ABS32 under LP64 is that, it's allowed in shared object and silently resolved at static linking time. No dynamic relocation entry is generate for it. R_AARCH64_ABS16 is allowed in shared object under both L64 and ILP32. It's resolved at static linking time as well. Under LP64, the address should be 64-bit. R_AARCH64_ABS32 relocation indicates an address that is only sized 32 bits which is meaningless in LP64 shared object. It's useful to error out. I have checked glibc dynamic linker code, R_AARCH64_ABS16 is not supported at all. So R_AARCH64_ABS16 should be reject in shared object completely. In this patch, R_AARCH64_ABS32 is rejected under LP64 in constant section of shared object. R_AARCH64_ABS16 is rejected in constant section of shared object in both ABI. This will sometimes provide useful information for buggy code.

2017-12-01readonly_dynrelocsAlan Modra6-0/+47
In early October, HJ Lu added support for a number of targets to "Dump dynamic relocation in read-only section with minfo". This extends that support to more targets, displays the symbol involved, and splits the existing function that sets TEXTREL into a "readonly_dynrelocs" and "maybe_set_textrel" function. I'll need "readonly_dynrelocs" if I ever get around to fixing "pr22374 function pointer initialization" fails. am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary needing text relocations with DT_TEXTREL. That's not good. xtensa also fails to do so but complains about "dangerous relocation: dynamic relocation in read-only section" so I reckon that is fine and have marked the test as an xfail. The other targets need maintainer attention. Curiously, the map file dump wasn't added for x86, so the map test currently fail on x86. It also fails on alpha, am33_2.0, arc, bfin, hppa64, ia64, m68k, mips, mn10300, nios2, score and vax. cris complains with "tmpdir/textrel.o, section .rodata: relocation R_CRIS_32 should not be used in a shared object; recompile with -fPIC" so I've marked it as an xfail. bfd/ * elf32-hppa.c (maybe_set_textrel): Print symbol for map file output. * elf32-ppc.c (maybe_set_textrel): Likewise. * elf64-ppc.c (maybe_set_textrel): Likewise. * elf32-arm.c (readonly_dynrelocs): New function.
