[Utility] Fix ArchSpec.MergeFrom to correctly merge environments
ClosedPublic

Authored by xiaobai on Feb 25 2019, 11:03 PM.

Details

Summary

This behavior was originally added in rL252264 (git commit 76a7f365da)
in order to be extra careful with handling platforms like watchos and tvos.
However, as far as triples go, those two (and others) are treated as OSes and
not environments, so that should not really apply here.

Additionally, this behavior is incorrect and can lead to incorrect ArchSpecs.
Because android is specified as an environment and not an OS, not propogating
the environment can lead to modules and targets being misidentified.

Will do. It looks like the dependent diff might change significantly so I'm going to rebase this on top of master instead since the functionality isn't technically tied to the dependent diff.
