[cfe-dev] -target or --target

[Renato Golin]

Hi folks,

I'm writing a document on cross-compilation and there is an issue about
using "--target=" instead of "-target ". Is this the new preferred format
by the community at large? Are we deprecating the old format?

Also, is "-gcc-toolchain" the same as "-ccc-gcc-name" ? Which one is
preferred to use from now on? Why not "--gcc-toolchain="?

Thanks,
