[llvm-commits] (autoconf) Build ASan runtime for ARM/Android

[Evgeniy Stepanov]

Those define the host platform (i.e. the one where compiler runs). The
idea here is to build compiler-rt for all possible target platforms.
We already do it for x86 and x86_64 when building on x86_64, and, with
this option, will be able to do it for android as well.
