We\njust assume llvm-libc has been updated to the same version before doing\nupdate, and I wrote that in the comments.\n\n- Define `_LIBCPP_ASSERTION_SEMANTIC_DEFAULT` in `__config_site`:\nhttps://github.com/emscripten-core/emscripten/pull/27428/changes/b119c8774ee522e8b9735269a984e9ebf8fb39f0\nhttps://github.com/llvm/llvm-project/pull/167636 forces us to define\n`_LIBCPP_ASSERTION_SEMANTIC_DEFAULT`. This defines it to follow the\nhardening mode.\n\n- Undefine `_LIBCPP_FILESYSTEM_USE_COPY_FILE_RANGE`:\nhttps://github.com/emscripten-core/emscripten/pull/27428/changes/e9f729619a2e19d8e6dc5db4ba2d2ec2e36fef06\nAfter https://github.com/llvm/llvm-project/pull/169405,\n`_LIBCPP_FILESYSTEM_USE_COPY_FILE_RANGE` was defined, which caused\nEmscripten to use `copy_file_range`. This commit adds\n`!defined(__EMSCRIPTEN__)` clause at the end to make\n`_LIBCPP_FILESYSTEM_USE_COPY_FILE_RANGE` undefined for Emscripten, as\nwas before this update.\n\n- Make `__cxa_thread_atexit` available for Emscripten:\nhttps://github.com/emscripten-core/emscripten/pull/27428/changes/638d0e11aa2a22e3bf9ee8a7d253fb967e884c22\nhttps://github.com/llvm/llvm-project/pull/116261 wrapped\n`__cxa_thread_atexit` with `#if defined(__linux__) ||\ndefined(__Fuchsia__)`, which caused it to be undefined in Emscripten.\nThis adds `defined(__EMSCRIPTEN__)` to make it available again.\n\n- Increase size expectations of `test_malloc_size*`:\nhttps://github.com/emscripten-core/emscripten/pull/27428/commits/c818aa22e6819fba6cbe4c80dff503d7c9cf7848\nThis increase seems to be mainly due to the changes of implementation of\n`std::num_get` in `libcxx/include/__locale_dir/num.h` in\nhttps://github.com/llvm/llvm-project/pull/121795. Note that we had a\nsimilar size increase due to changes in `std::num_put` in\nhttps://github.com/llvm/llvm-project/pull/133572 in LLVM 21 update\n(#26058).\n\n- Create `module.modulemap` from `module.modulemap.in`:\nhttps://github.com/emscripten-core/emscripten/pull/27428/changes/be1f0a7a7dad0b0f413351c3f96959830843d8fe\nlibcxx used to have `module.modulemap`, but since LLVM 21, it was\nchanged to `module.modulemap.in` in\nhttps://github.com/llvm/llvm-project/pull/134699. Rather than we copy\nthis manually in each update, this makes `update_libcxx.py` create\n`module.modulemap` from `module.modulemap.in` automaticaly.\n\n- Copy `default_assertion_handler.in` to `__assertion_handler`:\nhttps://github.com/emscripten-core/emscripten/pull/27428/changes/547432f0f330f78993df4acf0f37a8caab19a462\nSince LLVM 18, https://github.com/llvm/llvm-project/pull/77883 started\nto provide a default assertion handler and a way to override it.

Because `for..in` iterates over array index\nstrings (`\"0\"`, `\"1\"`, etc.), `bufId` received `\"0\"` on the first\niteration.

Under ASYNCIFY, however, the jsifier also wraps\nthese functions in `Asyncify.handleAsync`, so the proxied dispatch on\nthe main thread would start an asyncify unwind of the main thread\u0027s\nproxy-queue frame instead of returning the Promise. With assertions this\nhits the ASYNCIFY_IMPORTS abort; adding the import to ASYNCIFY_IMPORTS\nas the message suggests then fails with `TypeError: rtn.then is not a\nfunction`, since the wrapper returns the asyncify sleep sentinel (0)\nrather than the Promise.\n\nThe fix is for `Asyncify.handleAsync` to return the raw Promise when\nexecuting on behalf of a proxied caller\n(`PThread.currentProxiedOperationCallerThread` is set), satisfying the\nPROXY_SYNC_ASYNC contract.\n\nBehavior for the #27291 repro (blocking `poll()` on a pthread),\nbefore/after this change:\n\n* `-pthread -sPROXY_TO_PTHREAD -sASYNCIFY`: crashed before, works now\n(new test)\n* `-pthread -sPROXY_TO_PTHREAD`: unaffected, worked before and after\n* `-pthread -sASYNCIFY` (the issue as filed): no longer crashes, but\nstill hangs: the PROXY_SYNC_ASYNC completion requires the main thread\nevent loop (the limitation noted in #26000) while the main thread is\nblocked in `pthread_join`. Plain `-pthread` hangs the same way both\nbefore and after this change. Making that configuration either work or\nfail loudly seems worth a separate discussion.\n\nTest coverage: `core.test_poll_blocking_asyncify_pthread` runs the\nexisting test_poll_blocking.c under `-sPROXY_TO_PTHREAD -sASYNCIFY`,\nwhich aborted before this change.\n\n_Made with AI assistance under my review_" }, { "commit": "c8c8b8ae27ef360e9a5c86169df9d366f2373399", "tree": "928b612b97f69e873991df74d6efc81310d751d1", "parents": [ "597849e0051942f629c91cc4f932230ef66784a3" ], "author": { "name": "Sam Clegg", "email": "sbc@chromium.org", "time": "Mon Jul 20 23:47:30 2026" }, "committer": { "name": "GitHub", "email": "noreply@github.com", "time": "Mon Jul 20 23:47:30 2026" }, "message": "[sync_deps.py] Error out if target directory is not clean (#27391)" }, { "commit": "597849e0051942f629c91cc4f932230ef66784a3", "tree": "ec6a4e45f98a80e4e41098b44933f903d903f570", "parents": [ "1c6fa69b93dce22a5ce72249d434ae0dcac5cb5f" ], "author": { "name": "Sam Clegg", "email": "sbc@chromium.org", "time": "Mon Jul 20 23:25:57 2026" }, "committer": { "name": "GitHub", "email": "noreply@github.com", "time": "Mon Jul 20 23:25:57 2026" }, "message": "Allow environment variables in config strings.

Previously\nsuch builds failed in the JS optimizer\u0027s metadce (dead code elimination)\npass with:\n\n```\nAssertionError: could not find the assignment to \"wasmImports\".\n```\n\nThe reason is that metadce reconstructs the wasm⇄JS def/use graph by\npattern-matching the idioms a normal build emits — the `wasmImports`\nobject literal and `wasmExports[\u0027x\u0027]` member uses. Under ESM integration\nthose don\u0027t exist: the boundary is expressed with native ES module\nsyntax instead, which is exactly the simpler, tooling-visible def/use\ngraph this mode was designed to produce:\n\n```js\n// wasm exports received by the JS:\nimport { main as _main, memory as wasmMemory } from \u0027./a.out.wasm\u0027;\n// JS functions exported to the wasm:\nexport { _fd_write as fd_write };\n```\n\nSo rather than synthesise the old shapes, metadce now reads the real\nmodule bindings directly.\n\n* `emitDCEGraph` recognises `import {..} from \u0027./x.wasm\u0027` as wasm export\nnodes (collapsing aliases such as `memory`/`wasmMemory` onto a single\nnode) and `export { js as wasmName }` as wasm import edges, while\nleaving re-exports (`export { _main }`) to root naturally.\n* `applyDCEGraphRemovals` prunes unused specifiers from those same\n`import`/`export` statements.\n* `applyImportAndExportNameChanges` applies binaryen\u0027s minified names to\nthe wasm-facing side of each specifier, e.g.\n\n ```js\n import { malloc as _malloc } from \u0027./a.out.wasm\u0027;\n export { _fd_write as fd_write };\n ```\n\n becomes\n\n ```js\n import { c as _malloc } from \u0027./a.out.wasm\u0027;\n export { _fd_write as d };\n ```\n\nThe local binding is preserved (an unaliased `memory` becomes `b as\nmemory`, not a broken `b`).\n\nWhen `-sSOURCE_PHASE_IMPORTS` is also enabled, the glue additionally\nemits a source-phase import of the wasm module itself:\n\n```js\nimport source wasmModule from \u0027./a.out.wasm\u0027;\n```\n\nThat specifier is an `ImportDefaultSpecifier` binding the module (not a\nwasm export), so it has no `.imported`. `isImportFromWasm` matched any\nimport whose source ends in `.wasm` and `emitDCEGraph` then threw\n`TypeError: Cannot read properties of undefined (reading \u0027name\u0027)`\nreading `spec.imported.name`. It now gates on `!node.phase` so only\nvalue-phase `.wasm` imports (the export bindings) are treated as export\nedges; source/defer-phase imports are left alone.\n\nTwo supporting changes keep the two module interfaces in sync:\n\n* `building.py` — under ESM integration any export binaryen drops\n(including internal ones like the indirect function table) is also\ndropped from the JS `import`, so the JS never imports something the wasm\nno longer exports.\n* `link.py` — import/export *name* minification stays on for ESM, but\nimport *module name* minification is disabled, since every import is\nrewritten to the single support-module source by `create_esm_wrapper`\nanyway (and minifying `env`→`a` would break that rewrite).\n\nTest coverage:\n\n* New `js_optimizer` fixtures exercising each pass on ESM-shaped input:\n`emitDCEGraph-esm`, `applyDCEGraphRemovals-esm`,\n`applyImportAndExportNameChanges-esm`.\n* New `emitDCEGraph-sourcePhaseImports` fixture covering the combined\n`SOURCE_PHASE_IMPORTS` + `WASM_ESM_INTEGRATION` case that previously\ncrashed.\n* New end-to-end `other.test_metadce_esm_integration` building\n`hello_world.c` with `-O3 -sWASM_ESM_INTEGRATION`, asserting the\ndangling table import is removed and names are minified consistently\n(the run is guarded on Node 25).\n\nResolves #27217.\n\n_Made with AI assistance under my review_" }, { "commit": "f062699d80637fe67b5c07bbaf2611174877b271", "tree": "3a4cf2348662f5e17f415475bf0163de68c7193a", "parents": [ "3f023523f14b03155a8f2fdcf231ee6790761e61" ], "author": { "name": "stephenduong1004", "email": "stephenduong@google.com", "time": "Thu Jul 16 18:28:53 2026" }, "committer": { "name": "GitHub", "email": "noreply@github.com", "time": "Thu Jul 16 18:28:53 2026" }, "message": "Support multi-value returns in TS definitions (#27332)\n\n`wasm-bindgen` generates WebAssembly functions with multiple return\nvalues, so we need to remove the assertion that enforces a single return\ntype in tools/emscripten.py.
