[cfe-dev] Using clang-query for matching C++11 attributes

[LUIS MIGUEL SANCHEZ GARCIA]

Hi all,

I'm trying to extract the compound or single statement contained into an
C++11 attribute using "clang-query".


For example:

- file.cpp contains:

int main()
{
    int a = 5;
    int b = 6;

*    [[own::decl]] //included in my clang version*
*    for (int i=0;i<100;i++){*
* auto c = a + b;*
*    }*
    auto j1 = 2*a ;

    return 0;
}

- using clang-query -extra-arg="-std=c++1y" file.cpp --
clang-query>set output dump
clang-query>match */* something */*

and obtain as result something like:

Match #1:

Binding for "root":
AttributedStmt 0x30cd8f0 </tmp/test01.cpp:8:5, line:11:5>
|-OWNdeclAttr 0x30cd8e0 <line:8:7, col:12>
`-ForStmt 0x30cd8a8 <line:9:5, line:11:5>
  |-DeclStmt 0x30cd580 <line:9:10, col:17>
  .......


I would like to use something similar to the example of hasAttr() (which it
does not work) found in
http://clang.llvm.org/docs/LibASTMatchersReference.htmlMatcher<Decl>hasAttrattr::Kind
AttrKind

Matches declaration that has a given attribute.
> Given
>   __attribute__((device)) void f() { ... }
> decl(hasAttr(clang::attr::CUDADevice)) matches the function declaration of
> f.


Thanks!
Regards,
Luis.
