x86: Dump local IFUNC functions in the map file
Dump local IFUNC functions in the map file when generating IRELATIVE
relocations if -Map is used.
bfd/
* elf32-i386.c (elf_i386_check_relocs): Set local IFUNC symbol
name. Use local IFUNC symbol name string to report unsupported
non-PIC call to IFUNC function.
(elf_i386_relocate_section): Dump local IFUNC name with minfo
when generating R_386_IRELATIVE relocation.
(elf_i386_finish_dynamic_symbol): Likewise.
* elf_x86_64_check_relocs (elf_x86_64_check_relocs): Set local
IFUNC symbol name.
(elf_x86_64_relocate_section): Dump local IFUNC name with minfo
when generating R_X86_64_IRELATIVE relocation.
(elf_x86_64_finish_dynamic_symbol): Likewise.
ld/
* testsuite/ld-ifunc/ifunc-1-local-x86.d: Pass
"-Map tmpdir/ifunc-1-local-x86.map" to ld and check
ifunc-1-local-x86.map.
* testsuite/ld-ifunc/ifunc-1-x86.d: Pass
"-Map tmpdir/ifunc-1-x86.map" to ld and check ifunc-1-x86.map.
* testsuite/ld-ifunc/ifunc-1-local-x86.map: New file.
* testsuite/ld-ifunc/ifunc-1-x86.map: Likewise.
