Description
The AArch64 port no longer works after the commit for 8141132. This is because string_compare and string_equals in C2 now take a byte count rather than a char count.
Comments
It's also because string_indexof is no longer guaranteed that substr.count <= string.count, so we have to check that ourselves.
