Just to clarify, this change doesn't happen in r151489, but that is the 
revision I tested against.

This seems related to r150682 -> 
http://www.mail-archive.com/cfe-commits@cs.uiuc.edu/msg46100.html
(which seems to give a way to workaround the evolution)

HTH.

The attached patch fixes it for me on clang/llvm r151926.
I have added a local function getConstructor which might be overkill/ not fit 
with the styleguide ...
In wyu_ast_util.cc GetTplTypeResugarMapForFunction() I removed the special 
handling for NewExpr because it seems to have moved to ConstructorExpr 
completely.

Fabio, thanks for your patch.  I'm no longer really working on iwyu, so am not 
noticing when the code regresses; thanks for keeping a look-out.

Your patch looks fine.  My only suggestions are stylistic: rename 
getConstructor to GetConstructor, and put it in iwyu-ast-util, which seems to 
be its logical home.  (No reason to limit its use to just the one function it's 
used in now, I don't think.)

Once you've done that, feel free to commit.  I will need to give you commit 
access.  Is the gmx address the right one to add, or would you prefer another?

Original comment by csilv...@gmail.com on 6 Mar 2012 at 11:11

GoogleCodeExporter commented 9 years ago
Ok, done. Yes the gmx address is fine.

Looks good.  Only comment: I'm surprised this line compiles:
} CXXConstructorDecl * GetConstructor(clang::CXXNewExpr* expr);

Doesn't it need to be
   clang::CXXConstructorDecl
?

Also, one style nit: the style in the .h file seems to be to put the * to the 
left:
   CXXConstructorDecl* GetConstructor(clang::CXXNewExpr* expr);
Might as well do it that way.

You should have commit access now!  Let me know if you have any trouble.

I'm sorry the last patch was faulty, this one should work. It compiles and 
passes all tests except badinc. 

I did not recieve any credentials for the svn yet.

Glad you got it checked in -- thanks for fixing things up!

The goal is that all tests should pass, including badinc.  What is the failure? 
 Do you have a fix that looks right?

not yet. And I got a new linking failure since I updated clang today, so not 
realy sure how to proceed.
I also only just started looking into iwyu (and clang) in depth just now, so it 
will probably take me a bit. here is the error log ...

Looks like issue #22 Test badinc fails on mac @ r62. Are you using Mac OS X?

Attached patch fixes the destructor issue:

  I2_TemplateClass::~I2_TemplateClass<FOO> is defined in "tests/badinc-i2-inl.h", which

This seems to be the only remaining problem with the CXXNewExpr handling, as 
we've discussed on the list.

Thanks for patch, Kim. Based on it I've done a few more changes.

In Clang r150682 was changed how CXXConstructorDecl is handled in CXXNewExpr - 
instead of storing it separately, now it is stored as one of subexpressions and 
that's why it is traversed and visited automatically. That's why we don't need 
to handle constructor call in TraverseCXXNewExpr(), it will be handled in 
TraverseCXXConstructExpr(). Also change in traversal caused unnecessary 
TraverseImplicitDestructorCall(), which is now avoided if CXXConstructExpr is 
in CXXNewExpr. Also I've removed unnecessary function and cleaned up style a 
little bit.

Kim, can you review this patch?

All tests (62 of them) pass on Linux.

If I understand this correctly, you no longer handle CXXNewExpr, except for 
overloaded operator new? I had that thought as well to get rid of the reports 
that only differ in column #. Glad it seems to work!

And I like IsCXXConstructExprInNewExpr -- the GetConstructor method looked a 
little atypical earlier.

It took me a while to see what you changed in VisitCXXNewExpr, but I like the 
style changes. They're so small they might as well go in the same commit.

All in all, looks good, please commit!
