Here is the result of my little investigation on gcc testsuite failures. abi/mangle4: template function definition. fail in afcxx-anonymous abi/mangle8: template method operator() definition. fail in afcxx-disambiguate abi/mangle12: template function definition. fail in afcxx-disambiguate abi/mangle14: abi/mangle15: template fail in afcxx-anonymous compat/init-ref2_y: operator && doesn't work. fail in afcxx-disambiguate eh/cleanup1: declaration of 4000 class attributes, sglr error: 'too many ambiguities'. expr/static_cast3: inheritance with a parameterized class. fail in afcxx-disambiguate inherit/access3: template method definition. fail in afcxx-disambiguate init/addr-const1: use of static and non-static class attribute in a struct constructor. fail in afcxx-disambiguate init/array11: C code, simple cast with a typedef type. fail in afcxx-disambiguate init/array6: char arr [2][4] = { "one", "two" }; doesn't parse. fail in afcxx-disambiguate init/copy2: init/copy3: struct s {}; s a = s (); fail in afcxx-disambiguate init/elide1: operator &&. init/empty1: strange base class initialization. fail in afcxx-disambiguate init/init-ref2: operator &&. init/new9: template use. fail in afcxx-disambiguate init/ref2: same as init/copy2. lookup/disamb1: call to a method in a base class. lookup/koenig2: same as abi/mangle8. lookup/scoped3: same as lookup/disamb1. lookup/template1: basic template function (parametrized by an int) use. opt/cfg2: fail in afcxx-disambiguate opt/cfg3: opt/cleanup1: opt/const1: these tests are too big, i don't want to investiguate further. opt/inline1: struct A {}; template <typename, typename> struct B {}; typedef B <int, int> C; fail in afcxx-disambiguate opt/local1: declaration of a pure virtual method in a inner class. fail in afcxx-disambiguate opt/mmx1: opt/nrv1: opt/nrv2: operator &&. opt/pr6713: too big test, too many problems. opt/reload1: call to 'operator <<' with 1 argument. fail in afcxx-disambiguate opt/stack1: opt/unroll1: too big, too many problems. opt/static2: similar to lookup/template1. ******************* These piece of code are valid, but fail with parse-cxx. They are related to gcc failing tests. *** int i = 1 && 1; *** int f(); int a = f (); // or struct s {}; s a = s (); *** char a[2][4] = { "one", "two" }; *** // Call to a method in a base class. struct A { void f(); }; struct C : public A { void g() { f(); }; }; *** // Declaration of a pure virtual method in a inner class. struct O { struct I { virtual bool f() = 0; }; }; *** // Call to 'operator <<' with 1 argument. struct A { void operator << (int s) {} void f() { return operator << (0); } }; *** struct A {}; struct B { B(int, const A&); }; B t(1, A()); *** // Strange base class initialization. class a {}; class c : a { c() : a(a()) {} }; *** struct A {}; template <typename, typename> struct B {}; typedef B <int, int> C; *** template <class T> struct a {}; struct b : a<int> {}; -- Les trous noirs sont les endroits ou Dieu divisa par zero.
