Accidentally assigned myself. Removing assignment.

@akoeplinger @steveisok what's the status on this? I would really want to remove the rsp file as it bloats non Mono test builds as well.

[akoeplinger]

We removed the main .rsp file with #2087, the macOS one with #32585 and Windows is in progress here: #32592.

The remaining .rsp files are just a couple lines so there's no "bloat" :)

Thanks for the update. Is somebody working on removing the remaining ones: linux, interpreter and interpreter_arm64?

The remaining .rsp files are just a couple lines so there's no "bloat" :)

I wasn't just talking about file size bloat here but also about infrastructure:

runtime/eng/testing/tests.targets

Lines 79 to 90 in 5aff3be

	<!-- Generate Mono .rsp file -->
	<!-- TODO: remove when rsp files are removed: https://github.com/dotnet/runtime/issues/1980. -->
	<ItemGroup>
	<_rspFile Include="$(TestRspFile)" Condition="'$(TestRspFile)' != ''" />
	<_rspFile Include="$(MonoProjectRoot)netcore\CoreFX.issues_linux.rsp" Condition="'$(TargetOS)' == 'Linux'" />
	<_rspFile Include="$(MonoProjectRoot)netcore\CoreFX.issues_windows.rsp" Condition="'$(TargetOS)' == 'Windows_NT'" />
	</ItemGroup>
	<ItemGroup>
	<_rspFileContent Include="$([System.IO.File]::ReadAllText(%(_rspFile.Identity)))" Condition="'$(TargetOS)' != 'OSX'" />
	</ItemGroup>
	<WriteLinesToFile File="$(MonoRspFile)" Lines="@(_rspFileContent)" Overwrite="true" />

. This is currently running always, as we share built libraries test assemblies between coreclr and mono.

Yeah, @MaximLipnin is working on removing the rest.
