[PATCH] D107242: [AIX] Define __HOS_AIX__ macro

[Joerg Sonnenberger via Phabricator via cfe-commits]

joerg added a comment.

clang is fundamentally a cross-compiler only. I don't see any point for having host-specific branches in this case at all. Either the macro should be specified for the target all the time or not at all, but it should most definitely not depend on the host. That's actually breaking a number of existing use case for clang in subtle ways, e.g. partially preprocessed files (`-frewrite-includes`) should behave the same on any platform given the same command line.
