[GOLD] PowerPC64 ELFv2 notoc support Calls from notoc functions via the PLT need different stubs. Even calls to local functions requiring a valid toc pointer must go via a stub. This patch provides the support in gold. elfcpp/ * powerpc.h (R_PPC64_PLTSEQ_NOTOC, R_PPC64_PLTCALL_NOTOC): Define. gold/ * powerpc.cc (Target_powerpc::maybe_skip_tls_get_addr_call): Handle notoc calls. (is_branch_reloc): Template on size. Return true for REL24_NOTOC. Update all callers. (max_branch_delta): Likewise. (Target_powerpc::Branch_info::make_stub): Add a stub for notoc calls to functions needing a valid toc pointer. (Target_powerpc::do_relax): Layout stubs again if any need resize. (add_12_11_12, addi_12_11, addis_12_11, ldx_12_11_12, ori_12_12_0), (oris_12_12_0, sldi_12_12_32): Define. (Stub_table::Plt_stub_ent): Add notoc_ and iter_ fields. (Stub_table::Branch_stub_key, Branch_stub_key_hash): Rename from Branch_stub_ent and Branch_stub_ent hash. Remove save_res_ from key. (Stub_table::Branch_stub_ent): New struct. (class Stub_table): Add need_resize and resizing vars. (Stub_table::need_resize, branch_size): New accessors. (Stub_table::set_resizing): New function. (Stub_table::add_plt_call_entry): Handle notoc calls and resizing on seeing such or a tocsave stubs after a normal stub using the same sym. (Stub_table::add_long_branch_entry): Similarly. (Stub_table::find_long_branch_entry): Return a Branch_stub_ent*. (Stub_table::define_stub_syms): Adjust (Stub_table::build_tls_opt_head, build_tls_opt_tail): New functions.

(Stub_table::do_write): Separate loop for ELFv2 stubs, handling notoc calls. Simplify ELFv1 loop. Output notoc branch stubs. Use build_tls_opt_head and build_tls_opt_tail.

[binutils, ARM, 10/16] BFCSEL infrastructure with new global reloc R_ARM_THM_BF12 This patch is part of a series of patches to add support for Armv8.1-M Mainline instructions to binutils. This adds infrastructure for the BFCSEL instructions which is one of the first instructions in Arm that have more than one relocations in them. This adds a new relocation R_ARM_THM_BF12. The inconsistency between external R_ARM_THM_BF12 and internal BFD_RELOC_ARM_THUMB_BF13 is because internally we count the static bit-0 of the immediate and we don't externally.
