Getting strcut member attributes

Project Infrastructure LLVM Dev List Archives
#1

Hi,

I need a help,

#define OPT
#define MAN

struct A
{
   int i;
   char* c;
};

struct B
{
  OPT A a;
  MAN int i;
};

After parsing the above .h file, how to get the attributes of B members specifically
for member A which is prefixed with OPT...

So far am able to get type of a as A but unable to OPT...as it might be preprocessed and as it is empty
it may discarded or...

regards
ragha

Hi ragha, as this is a clang question I suggest you ask on the clang mailing
list.

Best wishes, Duncan.

Are you talking about Clang's AST (in which case you should ask your question on cfe-dev, not here) or IR?
In either case, empty preprocessor defines are gone. There's no way to recover them. Instead, define OPT and MAN to be something like __attribute__((annotate("opt"))), which will be preserved.
