The impetus for cleaning up the LLVM lexer was the failure to properly match keywords as discussed in #1372. Partly this was due to a keyword missing but partly it was due to the use of
String#join
to create brittle regex patterns.This PR uses memoising singleton methods and the use of
Array#include?
to match against a set of keywords. Doing this reduces memory usage by only allocation the keyword strings when the method is called, allows for the keywords to be ordered alphabetically which aids in legibility and, frankly, just looks nicer.Finally, the
addrspacecast
keyword is added.This fixes #1372.
