2021-05-25[GOLD] PR27815, gold fails to build with latest GCCAlan Modra1-0/+5
Don't use nullptr, it requires -std=c++11 on versions of gcc prior to 6.1. It would be possible to arrange to pass -std=c++11 automatically when required (top level configure does that for gcc builds) but that seems overkill and since we're not up-to-date on the top level config files would mean someone would need to sync those over.

2021-03-30PR27625, powerpc64 gold __tls_get_addr callsAlan Modra1-0/+13
This patch supports linking powerpc64 glibc with gold, specifically the __tls_get_addr call in elf/dl-sym.c. That call lacks marker relocations tying it to the arg setup instructions, but the arg setup insns are also contructed lacking the usual relocations on a Global Dynamic TLS code sequence. So there is no chance that anything in that sequence might be wrongly edited by the linker. In fact, the aim of linking glibc could have been supported by simply omitting the error whenever TLS optimisation is disabled, as it is when linking a shared library. The patch goes further than that, disabling TLS GD and LD sequence optimisation on a per-object basis for object files lacking marker relocs. PR gold/27625 * powerpc.cc (Powerpc_relobj): Add no_tls_marker_, tls_marker_, and tls_opt_error_ variables and accessors. (Target_powerpc::Scan::local, global): Call set_tls_marker and set_no_tls_marker for GD and LD code sequence relocations. (Target_powerpc::Relocate::relocate): Downgrade the "lacks marker reloc" error to a warning when safe to do so, and omit the error entirely if not optimising TLS sequences.

2020-12-13Fix incremental tests using gcc 9, which adds Gnu properties sections.Cary Coutant1-0/+6
During an incremental link, we should simply ignore the Gnu properties sections. We were not handling them properly -- failing to process the properties from the base file. While that could be fixed, the property sections are meant for deployed binaries, and incremental linking is for development, so keeping the properties sections just adds to the likelihood of forcing a full link sooner. gold/ PR gold/23539 * object.cc (Sized_relobj_file::layout_gnu_property_section): Ignore Gnu properties during incremental links.
