Use ErrorOS for log messages as well as error log are also diagnostics so it seems like they should to the same place as errors and debug messages. Without this change when I enable --verbose those messages go to stdout, but when I enable "-mllvm -debug" those messages go to stderr (because dbgs() goes to stderr by default). So I end up having to do this a lot: lld <args> > output_message 2>&1 Differential Revision: https://reviews.llvm.org/D41033 llvm-svn: 320427

Do not read the same .lib file more than once. In the following command line, lld-link foo/bar.lib /defaultlib:bar.lib "/defaultlib:bar.lib" should be a nop even if a file with the same name exists in other library search path.

lld-link: Add a flag /lldignoreenv that makes lld-link ignore env vars. This is useful for enforcing that builds are independent of the environment; it can be used when all system library paths are added via /libpath: already. It's similar ot cl.exe's /X flag. Since it should also affect %LINK% (the other caller of `Process::GetEnv` in lld/COFF), the early-option-parsing needs to move around a bit. The options are: - Add a manual loop over the argv ArrayRef and look for "/lldignoreenv". This repeats the name of the flag in both Options.td and in DriverUtils.cpp. - Add yet another table.ParseArgs() call just for /lldignoreenv before adding %LINK%. - Use the existing early ParseArgs() that's there for --rsp-quoting and use it for /lldignoreenv for %LINK% as well. This means --rsp-quoting and /lldignoreenv can't be passed via %LINK%. I went with the third approach. Differential Revision: https://reviews.llvm.org/D67456 llvm-svn: 371852
