[Directize] Add a flag to consider initial table contents immutable (#4942)
In LLVM output and probably others, the initial table contents are never
changed. We may append later, but we don't trample the initial table
entries. As a result, with this new flag we can turn indirect calls on those
offsets into direct ones:
--directize-initial-tables-immutable

Current Trunk ------------- +- Add a new flag to Directize, `--pass-arg=directize-initial-contents-immutable` + which indicates the initial table contents are immutable. That is the case for + LLVM, for example, and it allows us to optimize more indirect calls to direct + ones. (#4942) - Change constant values of some reference types in the C and JS APIs. This is only observable if you hardcode specific values instead of calling the relevant methods (like `BinaryenTypeDataref()`). (#4755) |
