[cfe-commits] clang Cygwin slow startup

[James Boulton]

Seems to be the same as "clang --version".

If you run it, then run it again it gets quicker. So to me that does suggest caching of DLL's or something like that.

Just compiled a version with .NET and running it is instant, but isnt working as I want just yet. Might be the answer, though.

The Cygwin version definitely is very slow to start up.

  How fast is clang -cc1 -version?

    No, it's nothing that silly. It's configured with --enable-optimised and says it's building as release+asserts.

        Hi, I've just build the llvm setup on cygwin and clang takes a long time to start up.

        For instance "clang --version" takes around 4-5 seconds before displaying the version info. This is the same for any command issued to clang and it appears to be just how long it is taking to load up the exe + dll's.

        Is there anything I can do to speed this up as it's currently unusably slow, but otherwise working pefectly!


      Try building in Release mode.
