[wasm][coreclr] Get further in the runtime initialization (#116383)
* [wasm][coreclr] Get further in the runtime initialization Add corewasmhost binary to test runtime initialization Fix linking of the host binary with coreclr and interpreter Allow calling interpreter with arguments and handle return value Use fake precode stubs to pass the precode type and method desc Make alternate signal stack calls no-op on wasm Implement CallDescrWorkerInternal on wasm Fix PE image loading without RTR on wasm Do not use unsupported syscalls * Fix condition Co-authored-by: Adeel Mujahid <[email protected]> * Fix build The jit helpers are used later unconditionally * Update after merge * Feedback * Update after merge * Fix release build offsets * Build Debug runtime configuration on CI, so that interpreter is enabled * Fix build * Enable interpreter in all configuration on wasm Fix build * Build in Release again as we are missing debug packages * Move inline keyword Co-authored-by: Jan Kotas <[email protected]> * Feedback * Feedback * Fix release build * Feedback Do not special case missing mono_wasm_browser_entropy and just add it to helpers with an assert * Feedback * Feedback Use MethodDesc's GetInterpreterCode() instead of GetNativeCode() * Feedback Do not use FEATURE_JIT for callstub exclusion, until we support it on wasm, use TARGET_WASM instead. Also update build after merge * Feedback Use PORTABILITY_ASSERT * Feedback, add FEATURE_PEIMAGE_FLAT_LAYOUT * Revert mapping changes for PE loaded layout We use the flat layout now * Feedback, change call order of execute interp method * Feedback, change condition to avoid dynamic loads in corhost * Increase stub size to fit interpreter stub data This way we get further in the initialization log: stdout: Interpreter compile method System.AppContext:Setup(ptr,ptr,int) log: stdout: Interpreter compile method System.Diagnostics.Debug:Assert(bool,System.String) log: stdout: Interpreter compile method System.Collections.Generic.Dictionary`2[System.__Canon,System.__Canon]:.ctor(int,System.Collections.Generic.IEqualityComparer`1[System.__Canon]) log: stdout: Interpreter compile method System.Diagnostics.Debug:Assert(bool,System.String,System.String) log: stdout: Interpreter compile method System.Collections.Generic.Dictionary`2[System.__Canon,System.__Canon]:.ctor(int) * Update precode sizes, feedback and size check * Feedback, TODO, transition block * Feedback * Use coreclr_static library for wasm And do not build coreclr * Feedback Disable larger part of GCToOSInterface::Initialize than before * Feedback Make InitializeFlushProcessWriteBuffers no-op on wasm * Write barriers helper updated Co-authored-by: Jan Kotas <[email protected]> * Write barriers helper updated Co-authored-by: Jan Kotas <[email protected]> * Feedback Return false from ExecutableAllocator::IsDoubleMappingEnabled instead of making the double mapping init no-op on wasm * Make InitJITWriteBarrierHelpers no-op on wasm Co-authored-by: Jan Kotas <[email protected]> * Feedback Fix few asserts * Feedback Define PEIMAGE_FLAT_LAYOUT_ONLY in inc\switches.h * Feedback Replace __wasm__ where appropriate * Feedback Do not use __builtin_return_address on wasm * Feedback Add InvokeCalliStub to helpers * Feedback Update comments and remove unwanted fields * Feedback Add comment to the wasm specific call description data fields * Feedback Add portability assert in DispatchCallSimple to light up if we get called through this path * Fix build * Fix non-wasm build * Feedback Use FEATURE_JIT instead of not WASM check * Feedback Co-authored-by: Jan Kotas <[email protected]> * Feedback * Feedback Disable stack limit assert only in Debug configuration * Feedback Return flat layout from GetLoadedLayout when PEIMAGE_FLAT_LAYOUT_ONLY switch is enabled * Feedback Add more explanation in the comment and use the CodeSize in the assert * Add comment Co-authored-by: Jan Kotas <[email protected]> * Feedback Move _ReturnAddress macro ro pal.h * Fix build * Feedback Make FlushProcessWriteBuffers no-op on wasm * Feedback Fix path * Fix whitespace Co-authored-by: Jan Kotas <[email protected]> * Prefer TARGET_WASM Co-authored-by: Jan Kotas <[email protected]> * Update src/coreclr/pal/src/init/pal.cpp Co-authored-by: Jan Kotas <[email protected]> * Prefer TARGET_WASM Co-authored-by: Jan Kotas <[email protected]> * Prefer TARGET_WASM * Few more places to use more general TARGET_WASM * Prefer TARGET_WASM Co-authored-by: Jan Kotas <[email protected]> --------- Co-authored-by: Adeel Mujahid <[email protected]> Co-authored-by: Jan Kotas <[email protected]>
