  "message": "gdb/elfread: add debug output for GNU ifunc resolution\n\nAdd some debug prints throughout the ifunc resolution code, to be able\nto better understand what GDB does.  Add the new \"set debug gnu-ifunc\"\nknob to control it.\n\nAdd the debug_prefixed_printf_cond_func macro to implement\ngnu_ifunc_debug_printf_func, that takes an explicit function name.  This\nis needed to avoid showing \"operator()\" as the function name in the\ndebug message.\n\nHere is a sample session with the new debug output enabled.\n\n    (gdb) b the_function\n    [gnu-ifunc] elf_gnu_ifunc_resolve_name: resolving name \"the_function\"\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_cache: resolving \"the_function\" by cache\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_cache: cache miss for \"the_function\"\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_got: resolving \"the_function\" by GOT\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_got: GOT entry \"the_function@got.plt\" points to 0x7ffff7fb7036\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: recording cache entry for \"the_function\" at 0x7ffff7fb7036\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: minimal symbol \"the_function@plt\" at 0x7ffff7fb7030 does not match addr 0x7ffff7fb7036, not caching\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_got: GOT entry \"the_function@got.plt\" points to 0x7ffff7fb2036\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: recording cache entry for \"the_function\" at 0x7ffff7fb2036\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: minimal symbol \"the_function@plt\" at 0x7ffff7fb2030 does not match addr 0x7ffff7fb2036, not caching\n    [gnu-ifunc] elf_gnu_ifunc_resolve_by_got: failed to resolve \"the_function\" by GOT\n    [gnu-ifunc] elf_gnu_ifunc_resolve_name: failed to resolve name \"the_function\"\n    Breakpoint 2 at gnu-indirect-function resolver at 0x7ffff7fa80e9\n    (gdb) c\n    Continuing.\n    [gnu-ifunc] elf_gnu_ifunc_resolver_stop: stop on resolver for \"the_function\"\n    [gnu-ifunc] elf_gnu_ifunc_resolver_stop: created resolver return breakpoint at 0x7ffff7fd7186\n    [gnu-ifunc] elf_gnu_ifunc_resolver_return_stop: stop on resolver return\n    [gnu-ifunc] elf_gnu_ifunc_resolver_return_stop: resolver for \"the_function\" returned resolved address\u003d0x7ffff7fad0e9, resolved pc\u003d0x7ffff7fad0e9\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: recording cache entry for \"the_function\" at 0x7ffff7fad0e9\n    [gnu-ifunc] elf_gnu_ifunc_record_cache: cached \"the_function\" -\u003e 0x7ffff7fad0e9 in objfile /home/simark/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/ifunc-resolver/libimpl.so\n\n    Breakpoint 2, the_function_impl_0 (caller_id\u003d1) at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/ifunc-resolver-libimpl.c:25\n    25        the_function_last_caller_id \u003d caller_id; /* break-in-impl */\n\nChange-Id: I64f667e3457feaedfe9bb530de58faaf22545fa5\nReviewed-By: Eli Zaretskii \u003celiz@gnu.org\u003e\nApproved-by: Kevin Buettner \u003ckevinb@redhat.com\u003e\n",
