We made that + assumption before, but it is incorrect in general, which caused problems. + The fixed behavior is to not assume it, but require the user to pass it in as + a flag, `--zero-filled-memory`. Large binaries with lots of empty bytes in the + data section may regress without that flag. Toolchains like Emscripten can + pass the flag automatically for users if they know it is right to assume, + which can avoid any regressions. (#3306) - `RefFunc` C and JS API constructors (`BinaryenRefFunc` and `ref.func` respectively) now take an extra `type` parameter, similar to `RefNull`. This is necessary for typed function references support. |
