[Mono] Fix all the issues related to enabling WasmStripILAfterAOT (do…
Browse files Browse the repository at this point in the history
…tnet#90436)

* Enable IL trim for WASM by default

* Make ILStrip available for local build

* Make all calling another method go through the logic to see if it could call an AOT'ed version of it before trying to interp compile it

* Add back accidentally removed line of code

* Update test to accommodate IL trim with WASM AOT

* Move jit_call_can_be_supported to mini-runtime, so it doesn't depends on the value of mono_use_interpreter

* Update var name

* Attempt to fix rebuild test failures

* Attempt to fix the file open issue with unicode on windows

* Attempt to fix unicode issue #2

* Enable g_fopen to have the capability of handling opening files with unicode name on all platforms

* Add comment

* Update comment

* Fix file indentation format

* Check if string contains non-ascii char

* Remove unused callback

* Remove redundant comment

* Update method name

* Fixed some method not found issues and remove the optimization for g_fopen

* Fix tailcall

* Disable tailcall optimization when calling a trimmed method

* Free method header

* Fix windows build error

* Free method header at the correct locatioin

* Fix the condition of skipping tailcall

* Fix test failure

* Move JIT/AOT call invoke away from MINT_CALL, as it is not needed there.

* Fix virtual tail call

* Address review feedback

* Put the trimmed assemblies in a new folder, output an updated list of assemblies and update _WasmAssembliesInternal with the new list

* Put trimmed assemblies in IntermediateOutputPath

* Remove TrimmedAssemblies

* Create trimmed assembly folder before the parallel run

* Try to fix the issue with missing item

* Fix parallelism issue

* Only start the trim when the assembly is newer than the output

* Add assembly item to the list, when

* Add some logging

* Fixed runtimeconfig.json file path issue and disabed failed tests

* Update parameter name

* Fix wasi build

* Use the correct parameter

* Fix runtime test failure

* WasmAppBuilder: runtimeconfig.json path can be null

* cleanup

* ILStrip: fix typo in id name

* Cleanup

* ILStrip: ensure output assemblies are in the same order as the input. This is required for incremental builds.

* more cleanup

* Re-enable disabled tests

* Change the default value for WasmStripILAfterAOT to false

* Fix the issue with changing the value of WasmStripILAfterAOT between incremental builds

* Move the location of file deleting

* Use WasmAssembliesFinal or ResolvedFileToPublish during publish in WasmSDK

* Copy metadata in AOT compiler and when creating WasmAssembliesToBundle from ResolvedFileToPublish

* Add _WasmSatelliteAssemblies to WasmAssembliesFinal

* Add a wasm template test

* Include all non-dll ResolvedFileToPublish for ComputeWasmPublishAssets

* Add a blazor template test

* Address review feedback

* Update src/mono/wasm/Wasm.Build.Tests/Templates/WasmTemplateTests.cs

Co-authored-by: Ankit Jain <radical@gmail.com>

* Update parameter name

* Update usage of parameter

* Revert EmccCompile change

* MonoAOTCompiler: revert rebuilding when WasmStripILAfterAOT value changes

* Compress -> GZipCompress, and cleanup

* rework the tests

- to support webcil case
- run blazor app
- add cases for the default setting, and the opposite
- cleanup

* ILStrip.cs: Emit a message about stripping to make it obvious to the user

* WasmApp.targets: update comment

* Change default value to false and update test
