This is an issue because USE=test requires all LLVM_TARGETS to be enabled, therefore it's impossible to build dev-lang/rust with USE=test. CMake Error at CMakeLists.txt:925 (message): The target `ARC' is experimental and must be passed via LLVM_EXPERIMENTAL_TARGETS_TO_BUILD. -- Configuring incomplete, errors occurred! thread 'main' panicked at /var/tmp/portage/dev-lang/rust-1.74.1/work/rustc-1.74.1-src/vendor/cmake/src/lib.rs:975:5: command did not execute successfully, got: exit status: 1 build script failed, must exit now Reproducible: Always
Created attachment 883337 [details] build.log and emerge --info
# causes double bootstrap RESTRICT="test" so not a blocker
