Describe the bug
After upgrading to .NET 8, AOT compilation of my Blazor WASM application fails with the following very long error message ([...] is a placeholder for the AOT'd DLL paths):
WasmApp.Native.targets(418,7): Error MSB3073 : The command "llvm-size.exe -d --format=sysv [...] exited with code 9020.
This occurs after the assemblies themselves are AOt'd, following the "Compiling assembly bitcode files with -O2 ..." process.
I am running Windows 10.
The area in the WasmApp.Native.targets file is as follows: interestingly, my IDE says that the 'ConsoleToMsBuild' attribute is not allowed here, and highlights it as an error, I am not sure if this is a red herring:
<!-- for AOT builds we use llvm-size tool to collect size of the DATA segment in each object file -->
<Exec Command="llvm-size$(_ExeExt) -d --format=sysv @(_AOTObjectFile, ' ')"
Condition="'$(_WasmShouldAOT)' == 'true'"
IgnoreStandardErrorWarningFormat="true"
ConsoleToMsBuild="true"
StandardOutputImportance="low" StandardErrorImportance="low"
EnvironmentVariables="@(EmscriptenEnvVars)" >
My .csproj file has the following blazor-related properties:
<PropertyGroup>
<TargetFramework>net8.0</TargetFramework>
<RunAOTCompilation>true</RunAOTCompilation>
<BlazorWebAssemblyLoadAllGlobalizationData>true</BlazorWebAssemblyLoadAllGlobalizationData>
<BlazorEnableTimeZoneSupport>true</BlazorEnableTimeZoneSupport>
<Nullable>disable</Nullable>
</PropertyGroup>
The AOT process previously worked on .NET 7.
Expected Behavior
The AOT compilation process should execute as per .NET 7.
Steps To Reproduce
I have been unable to reproduce on a fresh .NET 8 project so far.
Exceptions (if any)
WasmApp.Native.targets(418,7): Error MSB3073 : The command "llvm-size.exe -d --format=sysv [...] exited with code 9020.
.NET Version
8.0.100
Anything else?
I am invoking the publish process from the command line to an IIS folder on my local machine.
My IDE is Rider 2023.3.2.
