• File bs/builtins/operators/comma.cpp — part of check-in [cde0c6d0e3] at 2019-06-19 19:49:50 on branch trunk —
  • parser: don't hardcode the builtins identity prefix in the rule helpers anymore.
  • builtins: move the common identity prefix used by all builtins into a separate function, to be able to easily change it.
  • builtins: prepend the CompileTime domain specifier to the root builtin identity.
  • sema: don't store the domain separately, extract it from the identity when needed instead.
