sunfish added a comment. This looks nice!
> __wasm_init_tls(calloc(__builtin_wasm_tls_size(), 1)); Would it make sense to change the API contract for `__wasm_init_tls` to guarantee that initializes all bytes (with zeros as needed)? `__wasm_init_tls` knows what bytes it's initializing, so we could use plain `malloc` instead of `calloc` and avoid redundant zero initialization of those bytes. ================ Comment at: llvm/lib/Target/WebAssembly/WebAssemblyISelLowering.cpp:1111 + + return DAG.getNode(ISD::ADD, DL, VT, TLSBase, TLSOffset); +} ---------------- It looks like this supports local-exec, but would need to be extended to handle initial-exec or the other TLS models. Assuming this is correct, could you add a check for the TLS model and `report_fatal_error` on unsupported models?
