描述
When using --experimental-lto-mode=full dsymutil complains about not being able to find (intermediate?) object files created during the LTO process. Example:
$ git clone git@github.com:apple/swift-nio.git
$ cd swift-nio
$ swift build --configuration release --experimental-lto-mode=full --verbose
warning: (arm64) /tmp/lto.o unable to open object file: No such file or directory
warning: (arm64) could not find object file symbol for symbol _$sSo14_sa_DoubleWordaMa
warning: (arm64) could not find object file symbol for symbol _$sSo14_sa_DoubleWordaMaTm
