r210360 switches "XFAIL: arm" to "XFAIL: arm-linux-gnueabi".

Probably because COMPILER_RT_TEST_TARGET_TRIPLE was the default triple in the monolithic build (x86_64-pc-linux-gnu).

One option is to XFAIL based on the entire triple.  So 'XFAIL: arm' -> 'XFAIL: arm-linux-gnueabi'.  My concern is that the list could get awkwardly long with something like 'XFAIL: arm-linux-gnueabi,arm-none-linux-gnueabi,armv7-linux-gnueabi,thumbv7-linux-gnueabi'.  Do we have other options?  Is it possible to make lit recognize "XFAIL: arm_linux" or perhaps "UNSUPPORTED: arm_linux" which would search 'available_features' like REQUIRES does?


> Could this be changed to REQUIRES: stable-runtime or XFAIL: unstable-runtime?

We can't write "XFAIL: unstable-runtime" instead of "REQUIRES: stable-runtime" because the test result is not deterministic.  Those tests inconsistently pass, fail or hang.

I've switched android bot to the standalone build and these started showing as "Unexpected Passing Tests". For some reason XFAIL: arm did not apply to arm-android in non-standalone build, though it does not matter now as it looks like we would be deprecating that.

Could this be changed to REQUIRES: stable-runtime or XFAIL:
unstable-runtime? Alternatively, we could introduce smth like arm-linux for use in XFAIL.
