AFAICT, `--header-filter` & `HeaderFilterRegex` exist to filter diagnostics
that occur in matching headers. These diagnostics are influenced by the
contents of system headers, but are ultimately emitted inside of source files
that have interesting lints, e.g.,
[ub] /l [ 19ms ] ~> cat test.cpp
#include <string.h>
void foo(void *a, const void *b, size_t n) {
memcpy(/*blah=*/a, b, n);
}
[ub] /l [ 2ms ] ~> clang-tidy --checks='bugprone-argument-comment' test.cpp
--header-filter='dont-match-anything' --
1 warning generated.
/l/test.cpp:3:10: warning: argument name 'blah' in comment does not match
parameter name '__dest' [bugprone-argument-comment]
memcpy(/*blah=*/a, b, n);
^
/usr/include/string.h:43:39: note: '__dest' declared here
extern void *memcpy (void *__restrict __dest, const void *__restrict __src,
^
[ub] /l [ 25ms ] ~> clang-tidy --checks='bugprone-argument-comment' test.cpp
--config 'HeaderFilterRegex: "dont-match-anything"' --
1 warning generated.
/l/test.cpp:3:10: warning: argument name 'blah' in comment does not match
parameter name '__dest' [bugprone-argument-comment]
memcpy(/*blah=*/a, b, n);
^
/usr/include/string.h:43:39: note: '__dest' declared here
extern void *memcpy (void *__restrict __dest, const void *__restrict __src,
^
[ub] /l [ 22ms ] ~>
So I don't think those help here.
