Previously clang AST prints the following declaration:
int fun_var_unused() {
int x __attribute__((unused)) = 0;
return x;
}
and
int __declspec(thread) x = 0;
as:
int fun_var_unused() {
int x = 0 __attribute__((unused));
return x;
}
and
int x = __declspec(thread) 0;
which is rejected by C/C++ parser. This patch modifies the logic to
print old C attributes for variables as:
int __attribute__((unused)) x = 0;
and the __declspec case as:
int __declspec(thread) x = 0;
