Summary: Suppress fixes for functions that are referenced within the
compilation unit outside of a call expression as the signature change
could break the code referencing the function.
We still issue a warning in this case so that users can decide to
manually change the function signature.

Summary:
clang-tidy should fix identifier naming even when the identifier is
referenced inside a macro expansion, provided that the identifier enters
the macro expansion completely within a macro argument.
For example, this will allow fixes to the naming of the identifier
'global' when it is declared and used as follows:
int global;
#define USE_IN_MACRO(m) auto use_##m = m
USE_IN_MACRO(global);

Hello, i would like to suggest a fix for one of the checks in clang-tidy and i should hope this one is the correct mailing list.
The check is modernize-avoid-bind.
Consider the following:
void bar(int x, int y);
namespace N {
void bar(int x, int y);
}
void foo(){
auto Test = std::bind(N::bar,1,1);
}
clang-tidy’s modernize-avoid-bind check suggests writing:
void foo(){
auto Test =[] {return bar(1,1);};
}
instead of:
void foo(){
auto Test = [] {return N::bar(1,1);};
}
So clang-tidy has proposed an incorrect Fix.

Summary:
This adds a diagnostic to the misc-use-after-move check that is output when the
use happens on a later loop iteration than the move, for example:
A a;
for (int i = 0; i < 10; ++i) {
a.foo();
std::move(a);
}
This situation can be confusing to users because, in terms of source code
location, the use is above the move. This can make it look as if the warning
is a false positive, particularly if the loop is long but the use and move are
close together.
In cases like these, misc-use-after-move will now output an additional
diagnostic:
a.cpp:393:7: note: the use happens in a later loop iteration than the move
