  "message": "libctf: don\u0027t run tests requiring deduplicating linker unless one is in use\n\nBefore now, we were relying on gcc -B to repoint GCC at our freshly-built\nlinker, and assuming we could use this to run tests that do linker dedup.\n\nThis is, alas, not reliable (building --with-ld\u003d/an/absolute/path bypasses\n-B searches for the linker), and we would like the libctf tests in\nparticular to not fail if the compiler uses a linker that cannot deduplicate\n(simply skipping such tests).\n\nAdd a new testsuite function that tries to link one of the lookup tests\u0027\ntestcases (which is known to produce conflicting types, i.e. a dict with\nper-translation-unit children) and then does an objdump and greps it for\nsigns of the per-translation-unit children.  If there are none, the linker\nprobably just concatenated the sections: i.e., it is not a linker that\ncan deduplicate CTF.\n\nlibctf/\n\tPR libctf/33162\n\t* testsuite/config/default.exp (objdump): Introduce.\n\t(OBJDUMPFLAGS): Likewise.\n\t* testsuite/lib/ctf-lib.exp (check_ctf_linker_dedup): New.\n\t* testsuite/libctf-lookup/lookup.exp: Use it.\n\t* testsuite/libctf-regression/libctf-repeat-cu.exp: Likewise.\n\t* testsuite/libctf-regression/regression.exp: Likewise.\n",
