...am parsing a C++ file using cindex.py and want to get the template parameters to a specific node. However, the tree seems to be different depending on if the template parameter is a struct/class or a simple type such as int or float. In the first case the template type is appended as a child to the VAR_DECL node (the TYPE_REF node seen in the example below), but this is not the case with for example int. Any hint on where the template type is located for int/float/etc? /joel de vahl Example code: template <typename T> class Test { T test; }; struct S { }; Test<int> test_int; Test<...

I am trying to build llvm-gcc4 on a amd64. I had to add the attached patch to get the build system to select the correct library. Now the build fails while compiling a code that has __builtin_va_copy. The attached test.i fails with: cc1: ../../trunk/gcc/llvm-convert.cpp:443: llvm::Value* TreeToLLVM::Emit(tree_node*, llvm::Value*): Assertion `(isAggregateType(((exp)->common.type)) == (DestLoc

Ciao, Duncan.

I did mark it as TREE_CONSTANT. Is that enough? -bw On Jan 5, 2009, at 2:03 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi Chris, > >> I think this change is fine and should go into the normal apple GCC >> as >> well.

No idea - if it works I guess it was enough :) I was actually thinking of TREE_STATIC: /* In a VAR_DECL, nonzero means allocate static storage.

This is also used in lots of other nodes in unclear ways which should be cleaned up some day. */ #define TREE_STATIC(NODE) ((N...
