    text
    copied!<p>I'm trying to get the entire code of the function body.</p> <p>I have the following code</p> <pre><code> bool VisitFunctionDecl(FunctionDecl *f) { Stmt *FuncBody = f-&gt;getBody(); stringstream SSAfter; SSAfter &lt;&lt; f-&gt;getBody(); SourceLocation ST = f-&gt;getSourceRange().getBegin(); ST = FuncBody-&gt;getLocEnd().getLocWithOffset(1); TheRewriter.InsertText(ST, SSAfter.str(), true, true); } </code></pre> <p>I have the following code example</p> <pre><code>int multiplyOrSum (int a, int b, bool t) { int c=0; if (a&lt;=0){ return 0; } if (t){ c= a*b; } else { c = a+b; } __asm { jz _P01 jnz _P01 // _emit 0e9h _P01: } return (c + multiplyOrSum(a-1, b, t)+ loopOne (-1)); } </code></pre> <p>After parsing with the code that i provided. The outcome is</p> <pre><code>int multiplyOrSum (int a, int b, bool t) { int c=0; if (a&lt;=0){ return 0; } if (t){ c= a*b; } else { c = a+b; } __asm { jz _P01 jnz _P01 // _emit 0e9h _P01: } return (c + multiplyOrSum(a-1, b, t)+ loopOne (-1)); } 02053B28 </code></pre> <p>What i want to achieve is</p> <pre><code>int multiplyOrSum (int a, int b, bool t) { int c=0; if (a&lt;=0){ return 0; } if (t){ c= a*b; } else { c = a+b; } __asm { jz _P01 jnz _P01 // _emit 0e9h _P01: } return (c + multiplyOrSum(a-1, b, t)+ loopOne (-1)); } { int c=0; if (a&lt;=0){ return 0; } if (t){ c= a*b; } else { c = a+b; } __asm { jz _P01 jnz _P01 // _emit 0e9h _P01: } return (c + multiplyOrSum(a-1, b, t)+ loopOne (-1)); } </code></pre> <p>Please advice. Thanks a lot</p> <p>EDIT : Basically what i want to do is to duplicate the function body.</p> <p>EDIT 2 :</p> <p>I have tried the following code with some editing to my original</p> <pre><code>bool VisitFunctionDecl(FunctionDecl *f) { Stmt *FuncBody = f-&gt;getBody(); stringstream SSAfter; SSAfter &lt;&lt; f-&gt;getBody(); LangOptions LangOpts; LangOpts.CPlusPlus = true; PrintingPolicy Policy(LangOpts); std::string s; llvm::raw_string_ostream as(s); FuncBody-&gt;printPretty(as, 0, Policy); SSAfter &lt;&lt; as.str() &lt;&lt; "\n"; SourceLocation ST = f-&gt;getSourceRange().getBegin(); ST = FuncBody-&gt;getLocEnd().getLocWithOffset(1); TheRewriter.InsertText(ST, SSAfter.str(), true, true); } </code></pre> <p>My output now is </p> <pre><code>int multiplyOrSum (int a, int b, bool t) { int c=0; if (a&lt;=0){ return 0; } if (t){ c= a*b; } else { c = a+b; } __asm { jz _P01 jnz _P01 // _emit 0e9h _P01: } return (c + multiplyOrSum(a-1, b, t)+ loopOne (-1)); } { int c = 0; if (a &lt;= 0) { return 0; } } </code></pre> <p>How am i going to get the entire body of the function? I have now gotten the first part. But what about the rest?</p>
