2020-06-26libctf, elfcpp, gold: do not assume that <byteswap.h> contains bswap_*Nick Alcock2-5/+20
At least one C library (uclibc-ng) defines some of these only when the compiler is GCC. We might as well test for all three cases and handle any of them being missing. Very similar code exists in libctf and split between elfcpp and gold: fix both. (Also sync up elfcpp with a change made to libctf swap.h a few months ago: since there is no out-of-line definition of the bswap replacements, they should be declared static inline, not just inline, to prevent the linker generating out-of-line references to them.)

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.
