radekdoulik · Radek Doulik · vargaz · web-flow · commit 724c4e1e2eea · 2022-02-02T23:02:19.000-05:00
* Initial changes for emscripten 2.0.34 * Use emcc-link.rsp in build targets * Use updated docker images * Fix compiler warnings Co-authored-by: Zoltan Varga <vargaz@gmail.com> * Put `--profiling-funcs` to `_EmccLinkFlags` * Fix build src/mono/mono/mini/mini-runtime.c:3407:25: error: ‘invoke’ undeclared (first use in this function); did you mean ‘revoke’? 3407 | invoke = mono_marshal_get_runtime_invoke_dynamic (); * Add shell to the environment Environment setting https://github.com/emscripten-core/emscripten/blob/2.0.34/src/settings.js#L616-L641 From emscripten 2.0.25 release notes - Support for the 'shell' environment is now disabled by default. Running under `d8`, `js`, or `jsc` is not something that most emscripten users ever want to do, so including the support code is, more often than not, unnecessary. Users who want shell support can enable it by including 'shell' in `-s ENVIRONMENT` (#14535). Example of the the size increase for bench sample: -a--- 12/10/2021 3:35 PM 382113 dotnet.js -a--- 12/13/2021 10:37 AM 383589 dotnet.js * Add emcc-link.rsp to PlatformManifestFileEntry * Feedback https://github.com/emscripten-core/emscripten/blob/2fda25eea756c78c8cb024aa5b6c2b188bf7990f/src/settings.js#L1173-L1176 -s EXPORT_ES6 is link option * Use new Emscripten workload * Remove unused variable * Add the emcc-link.rsp * Bump dotnet icu * Feedback * Do not add linker flags to compilation * Split `_EmccLDFlags` To avoid these errors: WasmApp.Native.targets(342,5): error : Failed to compile .../Microsoft.CodeAnalysis.CSharp.dll.bc -> /datadisks/disk1/work/B9F209B7/w/B1710A2F/e/wasm_build/obj/wasm/for-build/Microsoft.CodeAnalysis.CSharp.dll.o WasmApp.Native.targets(342,5): error : emcc: warning: linker setting ignored during compilation: 'TOTAL_MEMORY' [-Wunused-command-line-argument] WasmApp.Native.targets(342,5): error : emcc: warning: linker setting ignored during compilation: 'ERROR_ON_UNDEFINED_SYMBOLS' [-Wunused-command-line-argument] * Bump emscripten workload * Update windows helix queues * [wasm] Fix WBT running with nodejs When running with nodejs, the managed app would exit with code 42, but node would exit with 1. Use `process.exit` for node, instead of `mono_wasm_exit`.
