Unable to use $(EnableLLVM) with Android AOT #56386
Description
Description
Context: dotnet/android#5539
When using the new <MonoAOTCompiler/> task, it fails if you try to turn on $(EnableLLVM):
Microsoft.Android.Sdk.Aot.targets(65,5): Precompiling failed for C:\src\xamarin-android\bin\TestDebug\temp\NoSymbolsArgShouldReduceAppSize\obj\Release\android-arm64\linked\UnnamedProject.dll: '"C:\src\xamarin-android\bin\TestDebug\temp\SDK Ümläüts\ndk\toolchains\llvm\prebuilt\windows-x86_64\bin\opt"' is not recognized as an internal or external command,
operable program or batch file.
AOT of image UnnamedProject.dll failed.

I also get a build warning about opt.exe:
Microsoft.Android.Sdk.Aot.targets(65,5): [UnnamedProject.dll] '"C:\src\xamarin-android\bin\TestDebug\temp\SDK Ümläüts\ndk\toolchains\llvm\prebuilt\windows-x86_64\bin\opt"' is not recognized as an internal or external command,
opt.exe seems to be present in the AOT pack, why is it using LLVMPath to look for opt?
The value passed in for LLVMPath, seems to be correct:
But opt isn't located here, it is in the Mono AOT pack.
Note the folder used here (odd characters) is on purpose for testing, so this might be also be related: #56163.
I might be doing something wrong. Let me know, thanks!
Configuration
dotnet --version
6.0.100-rc.1.21376.3
Regression?
No, AOT on Android is new.
