2018-08-21Pack reloc_howto_structAlan Modra8-131/+138
This patch uses bitfields in reloc_howto_struct, reducing its size from 80 to 40 bytes on 64-bit hosts and from 52 to 32 bytes on 32-bit hosts (with a 32-bit bfd_vma). I've also added a new "negate" field rather than making the encoded "size" field do double duty as both a size and a flag. There was just one use of an encoded size of 8, which according to bfd_get_reloc_size meant 16 bytes, in vms-alpha.c ALPHA_R_LINKAGE. See git commit c3d8e071bf adding ALPHA_R_LINKAGE and git commit 8612a388f7 decoding size 8 in bfd_get_reloc_size. Since no other part of BFD handles 16 byte relocs, I've removed that encoding and special cased the ALPHA_R_LINKAGE size in vms-alpha.c. * reloc.c (reloc_howto_type): Typedef.

NEWHOWTO was promised way back in 1991 (git commit e5683622186). I doubt it's ever going to be implemented. This patch removes it, and tidies some reloc howtos.

2018-08-10Always clear h->verinfo.verdef when overriding a dynamic definitionH.J. Lu2-7/+11
When linker defines a symbol to override a dynamic definition, it should always clear h->verinfo.verdef so that the symbol won't be associated with the version information from the dynamic object. This happened to the symbol "_edata" when creating an unversioned dynamic object linking against: 1. libKF5ConfigCore.so.5.49.0 2. libKF5CoreAddons.so.5.49.0 3. libKF5I18n.so.5.49.0 4. libKF5DBusAddons.so.5.49.0 5. libQt5Xml.so.5.11.1 6. libQt5DBus.so.5.11.1 7. libQt5Core.so.5.11.1 Among them libQt5Xml.so.5.11.1 299: 000000000003e000 0 NOTYPE GLOBAL DEFAULT 18 _edata@@Qt_5 libQt5DBus.so.5.11.1 597: 0000000000092018 0 NOTYPE GLOBAL DEFAULT 18 _edata@@Qt_5 libQt5Core.so.5.11.1 2292: 00000000004df640 0 NOTYPE GLOBAL DEFAULT 21 _edata@Qt_5 2293: 00000000004df640 0 NOTYPE GLOBAL DEFAULT 21 _edata@Qt_5 The problem is triggered by 2 duplicated entries of _edata@Qt_5 in libQt5Core.so.5.11.1 which was created by gold. Before this commit, ld created the dynamic object with "_edata" in its dynamic symbol table which was linker defined and associated with the version information from libQt5Core.so.5.11.1. The code in question was there when the binutils source was imported to sourceware.org. When such a dynamic object was used later, we got: /usr/bin/ld: bin/libKF5Service.so.5.49.0: _edata: invalid version 21 (max 0) /usr/bin/ld: bin/libKF5Service.so.5.49.0: error adding symbols: bad value Tested with many ELF targets.

2018-08-08x86: Properly merge GNU_PROPERTY_X86_ISA_1_USEDH.J. Lu2-5/+29
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used. If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the corresponding x86 instruction set isn’t used.

2018-08-07PowerPC64 EH info for _notoc linkage stubsAlan Modra2-140/+264
This patch generates EH info for the new _notoc linkage stubs, to support unwinding from asynchronous signal handlers. Unwinding through the __tls_get_addr_opt stub was already supported, but that was just a single stub. With multiple stubs the EH opcodes need to be emitted and sized when iterating over stubs, so this is done when emitting and sizing the stub code. Emitting the CIEs and FDEs is done when sizing the stubs, as we did before in order to have the linker generated FDEs indexed in .eh_frame_hdr. I moved the final tweaks to FDEs from ppc64_elf_finish_dynamic_sections to ppc64_elf_build_stubs simply because it's tidier to be done with them at that point. bfd/ * elf64-ppc.c (struct map_stub): Delete tls_get_addr_opt_bctrl.

This patch fixes a bug in the handling of the __tls_get_addr_opt stub. Calls via this stub don't have a toc restoring instruction following the "bl", and the stub itself doesn't have an initial toc save instruction.

2018-08-05R_PPC64_REL24_NOTOC supportAlan Modra5-117/+599
R_PPC64_REL24_NOTOC is used on calls like "bl foo@notoc" to tell the linker that linkage stubs for PLT calls or long branches can't use r2 for pic addressing. Instead, new stubs that generate pc-relative addresses are used. One complication is that pc-relative offsets to the PLT may need to be 64-bit in large programs, in contrast to the toc-relative addressing used by older PLT linkage stubs where a 32-bit offset is sufficient until the PLT itself exceeds 2G in size. .eh_frame info to cover the _notoc stubs is yet to be implemented. bfd/ * elf64-ppc.c (ADDI_R12_R11, ADDI_R12_R12, LIS_R12), (ADDIS_R12_R11, ORIS_R12_R12_0, ORI_R12_R12_0), (SLDI_R12_R12_32, LDX_R12_R11_R12, ADD_R12_R11_R12): Define.

2018-08-05Lose _r2off in powerpc64 stub namesAlan Modra2-2/+6
Not a lot is conveyed by putting _r2off in a stub symbol that can't be seen by inspecting the stub code or the toc restoring instruction immediately after a call via such a stub. Also, we don't distinguish plt_call stub symbols from plt_call_r2save stub symbols, so this patch makes long branch and plt branch stub symbols consistent with that decision. bfd/ * elf64-ppc.c (ppc_build_one_stub): Lose "_r2off" in stub symbols. ld/ * testsuite/ld-powerpc/elfv2exe.d: Adjust for stub symbol change. * testsuite/ld-powerpc/tocopt6.d: Likewise.
