2018-04-09PowerPC inline PLT call supportAlan Modra2-0/+6
In addition to the existing relocs we need two more to mark all instructions in the call sequence, PLTCALL on the call itself (plus the toc restore insn for ppc64), and PLTSEQ on others. All relocations in a particular sequence have the same symbol. Example ppc64 ELFv2 assembly: .reloc .,R_PPC64_PLTSEQ,puts std 2,24(1) addis 12,2,puts@plt@ha # .reloc .,R_PPC64_PLT16_HA,puts ld 12,puts@plt@l(12) # .reloc .,R_PPC64_PLT16_LO_DS,puts .reloc .,R_PPC64_PLTSEQ,puts mtctr 12 .reloc .,R_PPC64_PLTCALL,puts bctrl ld 2,24(1) Example ppc32 -fPIC assembly: addis 12,30,puts+32768@plt@ha # .reloc .,R_PPC_PLT16_HA,puts+0x8000 lwz 12,12,puts+32768@plt@l # .reloc .,R_PPC_PLT16_LO,puts+0x8000 .reloc .,R_PPC_PLTSEQ,puts+32768 mtctr 12 .reloc .,R_PPC_PLTCALL,puts+32768 bctrl Marking sequences like this allows the linker to convert them to nops and a direct call if the target symbol turns out to be local. When the call is __tls_get_addr, each relocation shown above is paired with an R_PPC*_TLSLD or R_PPC*_TLSGD reloc to additionally mark the sequence for possible TLS optimization. The TLSLD or TLSGD relocs are emitted first. include/ * elf/ppc.h (R_PPC_PLTSEQ, R_PPC_PLTCALL): Define. * elf/ppc64.h (R_PPC64_PLTSEQ, R_PPC64_PLTCALL): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw): Add PLTSEQ and PLTCALL howtos.

elfcpp/dwarf.h with the new DW_CFA_DUP macro. From the original email: Note this brings in the interface files for libcc1/G++ as well, which we will be needing in GDB soon anyway. That commit renamed a method in the C interface and that required a small update to GDB's compile/ code, which I've included that in this patch to keep the tree building.

2017-08-29[GOLD] PowerPC tls_get_addr_optimizeAlan Modra3-0/+14
This implements the special __tls_get_addr_opt call stub for powerpc gold that returns __thread variable addresses without actually making a call to __tls_get_addr in most cases. Shared libraries that are loaded at program load time (ie. dlopen is not used) have a known layout for their __thread variables, and thus DTPMOD64/DPTREL64 pairs describing those variables can be set up by ld.so for the __tls_get_addr_opt call stub fast exit. Ref https://sourceware.org/ml/libc-alpha/2015-03/msg00626.html I really, really wish I'd used a differently versioned __tls_get_addr symbol than the base symbol to indicate glibc support for the optimized call, rather than having glibc export __tls_get_addr_opt. A lot of the messing around here, flipping symbols from __tls_get_addr to __tls_get_addr_opt, is caused by that decision. About the only benefit is that a user can see at a glance that their disassembled code is calling __tls_get_addr via the fancy call stub.. Anyway, we need references to __tls_get_addr to seem like they were to __tls_get_addr_opt, and in cases like the tsan interceptor, a definition of __tls_get_addr to seem like one of __tls_get_addr_opt as well. That's the reason for Symbol::clear_in_reg and Symbol_table::clone, and why symbols are substituted in Scan::global and other places dealing with dynamic linking. elfcpp/ * elfcpp.h (DT_PPC_OPT): Define. * powerpc.h (PPC_OPT_TLS): Define. gold/ * options.h (tls_get_addr_optimize): New option. * symtab.h (Symbol::clear_in_reg, clone): New functions.

2016-01-11Refactor gold to enable support for MIPS-64 relocation format.Cary Coutant3-0/+195
For MIPS-64, the r_info field in the relocation format is replaced by several individual fields, including r_sym and r_type. To enable support for this format, I've refactored target-independent code to remove almost all uses of the r_info field. (I've left alone a couple of routines used only for incremental linking, which I can update if/when the MIPS target adds support for incremental linking.) For routines that are already templated on a Classify_reloc class (namely, gc_process_relocs, relocate_section, and relocate_relocs), I've extended the Classify_reloc interface to include sh_type (which no longer needs to be a separate template parameter) as well as get_r_sym() and get_r_type() methods for extracting the r_sym and r_type fields. For scan_relocatable_relocs, I've extended the Default_scan_relocatable_relocs class by converting it to a class template with Classify_reloc as a template parameter. For the remaining routines that need to access r_sym, I've added a virtual Target::get_r_sym() method with an override for the MIPS target. In elfcpp, I've added Mips64_rel, etc., accessor classes and corresponding internal data structures. The MIPS target uses these new classes within its own Mips_classify_reloc class. The Mips64_ accessor classes also expose the r_ssym, r_type2, and r_type3 fields from the relocation. These changes should be functionally the same for all but the MIPS target. elfcpp/ * elfcpp.h (Mips64_rel, Mips64_rel_write): New classes.

Initial patch to enable gold aarch64 backend. This patch is just a skeleton which almost does nothing. It does not support ILP32 now. gold/ChangeLog: * aarch64.cc: New file * Makefile.am (TARGETSOURCES): Add aarch64.cc (ALL_TARGETOBJS): Add aarch64.$(OBJEXT) * Makefile.in: Regenerate. * configure.tgt: Add entries for aarch64*. * configure.ac: Likewise. * configure: Likewise. elfcpp/ChangeLog: * aarch64.h: New file. New enums for aarch64-elf64 relocations. * elfcpp.h (EM_AARCH64, SHT_AARCH64_ATTRIBUTES, PT_AARCH64_ARCHEXT, PT_AARCH64_UNWIND): New enum constant.
