> Is D correctly building that string_cst? Are D strings 0-terminated?
Yes, D strings are 0-terminated.
The way I've done it is, the string is constructed using
build_string(3, "foo")
but the TREE_TYPE is set to `char[4]` so that the terminating 0 is considered.
I'm sure it's like this because either GCC has a tendency to emit strings
side-by-side without the 0 so strlen("foo") could return 20, or there's an
optimization pass for strlen() that would otherwise evaluate strlen("foo") into
2 if I set the type of the literal as `char[3]`.
