c++ - Using libclang/libtooling -


I will retrieve all the structures and types defined in a project (as described in my previous question "") .

I chose the clag solution because this is my only way ... However, I found that only "good" tutorial is this: and still there are some questions left:

1) Is the pre-processor's instructions executed (#include, #define etc.)

2) How to get the type, and structure member?

In fact, for example * simple * code: 

  typedef struct {int i; Four ii; } S1; Typeface Straight S2 {int i; Structure S2S 2; } S2; Type 3 S3 Straight S3; Straight S3 {int i; Four ii; } S1 m_s1; S2m_s2; Straight S3 m_s3;   
 What is the method called a  clang :: recursiveASTVisitor  -derived class () and in what order? (And can you explain to me about recovering your data?)   
 
 
 OK , Peterson advised as a mat, I used to experiment.  
 1) Yes, AST is generated after the preprocessor. This allows all the information to be retrieved.  
 2) AST Traveler Depth-It's First. Instead of implementing the  VisitFoo (Foo *)  methods, you can re-implement the  TraverseFoo (Foo *)  method to get the beginning and end of each node lookup. :  
  Category Your Visitor: Public Recursive Last Visitor & lt; YourVisitor & gt; {// ... Virtual Bull Traversfu (Foo * F) {// To explore kids, first do some stuff b = rursiveASTVisitor & lt; YourVisitor & gt; :: TraverseFoo (f); // something to do after the return}}   
 Then to get the strokes (= records) and their members, just get struct and VisitFieldDecl to re-implement the Structure recorder To Field

Verilog Error: output or inout port "Q" must be connected to a structural net expression -

I get the error every time, I try to compile. I'm not sure why anyone can help is? I'm new to verilog.

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' .
