Hi,
This week, with the help of my mentors, I fixed the type mixmatches with _d_arraycatnTX. Then I fixed the bugs in my lowering and hook so that now all tests in druntime and phobos pass. The only failing test in dmd is test19688.d. The reason it fails is that passing __FUNCTION__ as an argument to another function makes it evaluate to an empty string, like in the code below:
string foo(string arg)
{
return arg;
}
T fooT(T)(T arg)
{
return arg;
}
void bar(string s = fooT(__FUNCTION__))
{
assert(s != "", s); // this fails
}
void baz(string s = foo(__FUNCTION__))
{
assert(s != "", s); // this fails
}
void taz(string s = __FUNCTION__)
{
assert(s != "", s); // this passes
}
void main()
{
taz();
baz();
bar();
}
I am not sure whether this is a bug or not and I am still investigating the issue. Once I figure it out and fix it or file a bug report, I'll raise a PR with the new _d_arraycatnTX hook. Then I'll continue with _d_newitem{T,iT,U}.
Thanks,
Teodor
