<div dir="ltr">Dear Clang Developers,<div><br></div><div>I am Shen, a beginner in
Clang and LLVM. I hope to add some attributes to some variables, and
check which variables include which attributes in my program. For
example, I can write a statement as:</div><div><br></div><div>int x __attribute_(foo); (here "foo" is an attribute defined by myself)</div><div><br></div><div>and
then how can i check whether x has attribute "foo"? In Clang manual,
the macro "__has_attribute" is just used for adding attribute for clang,
not for a concrete variable. Can you give me some help?</div><div><br></div><div><br></div><div>This
is the first time for me to use this way to ask questions about LLVM,
if anything wrong please let me know so i can use a better way to get
your help.</div><div><br></div><div>Thank you very much and have a nice day!<br><br></div><div>Shen<br></div></div>
