Hi,
When iterating through the AST I encounter BinaryOperator-s, part of an
IfStmt.
My question now is: how can I find which operator it is? E.g. ==, >=,
etc.
I'm using libclang.

Hi,
What is the order of the clang libraries when linking?
Currently I'm doing:
clang++ -fno-rtti `llvm-config --cxxflags` \
iterate.cpp \
`llvm-config --ldflags --libs --system-libs` \
-I/usr/lib/llvm-3.8/include -ggdb3 -std=c++11
-I/usr/include/llvm-3.8/llvm/Support -L
gt; return rso.str();

Hi,
I would like to parse a windows source. Using clang/llvm and
preferably under Linux.
I'm using:
std::vector arguments;
arguments.push_back("-fms-compatibility");
arguments.push_back("-fms-extensions");
arguments.push_back("-Wno-error=invalid-token-paste");
Hi,
I have an Expr object. How can I know if I can invoke
EvaluateAsBooleanCondition, EvaluateAsRValue, EvaluateAsInt and
EvaluateAsFloat ?
Because if I just call them on any Expr object, I get assertions like:
llvm/tools/clang/include/clang/AST/Type.h:612: const
clang::ExtQualsTypeCommonBase* c
Hi,
When I want to walk over the complete ast and visit each node (by using
a RecursiveASTVisitor<...>), do I need to implement all of TraverseDecl,
TraverseStmt and TraverseType? Because with all of those it looks like
some code is processed twice.
Second question: there are other Traverse...-me
Hi,
The Sun java compiler allows you to (from java) walk the AST and
investigate it. Each token is stored in an object. Each object has a
hash() method which uniquely identifies it.
Now I was wondering: can I do so with the LLVM tooling as well? I could
of course if I want to identify e.g. a func

Hi,
Something strange is happening while parsing using
std::unique_ptr au = clang::tooling::buildASTFromCodeWithArgs(code,
arguments, llvm::Twine(argv[i]));
I get a lot of errors and warning written to stderr (how can I stop that
apart from redirecting fd 2 to /dev/null?) but the following doe
Hi,
When I retrieve CastExpr::getType().getAsString() then I can get
something like:
const mytype_t *const **
Can I also somehow retrieve this tokenized?

Hi,
Finding the name and position of a function/method is easy:
DeclarationNameInfo dni = fd -> getNameInfo();
SourceRange dniSr = dni.getSourceRange(); // dniSr is position and length of
name in source file
std::string name = dni.getName().getAsString(); // name of function/method
But how can

The problem can be reproduced with this small example code:
http://files.slimwinnen.nl/n-nns.tgz
Just run make and then ./parse and you'll see it saying that "! NO
NestedNameSpecifier".
The test-code is test.cpp and the file it parses is example.cpp.

Hi,
I have a VarDecl instance for which I want to dissect the type.
E.g. a const int a would be a const, an int and the name a /
std::vector would be namespace std, vector and so on.
The first one is easy but the second one: I have no idea where to begin.
Sofar I have the following:
#include

Hi,
Given:
#define W(A) while(A)
void myfunc()
{
W(1) {
}
}
I would like retrieve a string for the "1" parameter of the while-macro.
Usually I would use:
Lexer::getSourceText(CharSourceRange::getCharRange(sr), sm,
LangOptions(), 0);
(with 'sr' being a SourceRange and
Hi,
I maybe very well not understanding something but it looks like a label
targetted by a goto, in a switch statement, gets missing: if I iterate
through the ast and emit all the stmt/expr/decls, then no label-type is
emitted.
#include
void myfunc(int a)
{
switch(a) {
The problem is that you were using CaseStmt::getRHS instead of
CaseStmt::getSubStmt.
No idea what getRHS is supposed to return then.

Hi,
How can I find the parent of a VarDecl? The scope it is in. E.g.
function/method or a global.
