[MIPS] Add generation of PLT entries with compact jumps for MIPS R6 Add a new option to get the linker to emit PLTs that use compact branches instead of delay slot branches. bfd/ * elfxx-mips.c (LA25_BC): New macro. (mips_elf_link_hash_table)<compact_branches>: New field. (STUB_JALRC): New macro. (mipsr6_o32_exec_plt0_entry_compact): New array. (mipsr6_n32_exec_plt0_entry_compact): Likewise. (mipsr6_n64_exec_plt0_entry_compact): Likewise. (mipsr6_exec_plt_entry_compact): Likewise. (mips_elf_create_la25_stub): Use BC instead of J for stubs when compact_branches is true. (_bfd_mips_elf_finish_dynamic_symbol): Choose the compact PLT for MIPSR6 with compact_branches. Do not reorder the compact branches PLT. Switch the lazy stub for MIPSR6 with compact_branches to use JALRC. (mips_finish_exec_plt): Choose the compact PLT0 for MIPSR6 when compact_branches is true. (_bfd_mips_elf_compact_branches): New function. * elfxx-mips.h (_bfd_mips_elf_compact_branches): New prototype. ld/ * emultempl/mipself.em (compact_branches): New static variable. (mips_create_output_section_statements): Call _bfd_mips_elf_compact_branches. (PARSE_AND_LIST_PROLOGUE): Add OPTION_COMPACT_BRANCHES and OPTION_NO_COMPACT_BRANCHES. (PARSE_AND_LIST_LONGOPTS): Add compact-branches, no-compact-branches. (PARSE_AND_LIST_OPTIONS): Add --compact-branches, --no-compact-branches. (PARSE_AND_LIST_ARGS_CASES): Handle the above. * ld.texinfo: Document --compact-branches, --no-compact-branches. * testsuite/ld-mips-elf/pic-and-nonpic-1-r6.dd: New test. * testsuite/ld-mips-elf/pic-and-nonpic-1-r6.nd: New test. * testsuite/ld-mips-elf/pic-and-nonpic-3a-r6.dd: New test. * testsuite/ld-mips-elf/pic-and-nonpic-3a-r6.gd: New test. * testsuite/ld-mips-elf/pic-and-nonpic-1a-r6.s: New test source. * testsuite/ld-mips-elf/pic-and-nonpic-3a-r6.s: New test source. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests. 2019-05-14 02:03:19 +02:00			`# GOT layout:`
