Swift 5.0 test failures on PowerPC

#1

Built and verified Swift 5.0 master on PowerPC(powerpc64le). I was able to run all the samples given in https://swift.org/getting-started/ which confirms that 'swiftc'(Swift compiler), REPL environment and LLDB debugger are working correctly. Also package manager seems to work fine. Built a sample package using the ported Swift 5.0 binaries.

I also invoked the build-toolchain to run the tests as well :-
utils/build-toolchain srtbundle --test

Following is the current status of the tests which are failing so far:-
4 warning(s) in tests.
Testing Time: 1774.53s

Failing Tests (19):

Any help would be greatly appreciated.

#2

Around 5 tests fail with " FileCheck error: '-' is empty. "
Tried adding " -allow-empty " to the FileCheck command line: build/buildbot_linux/llvm-linux-powerpc64le/bin/FileCheck. Still the tests fails on subsequest steps.
The failing tests are:-
swift/test/Driver/fuzzer.swift
swift/test/IRGen/objc_properties_jit.swift
swift/test/Index/Store/output-failure.swift
swift/test/Interpreter/generic_casts.swift
swift/test/remote-run/upload-stderr.test-sh

Most of the "'-' is empty" failures mean that the compiler crashed or exited before it output anything to FileCheck, so you'll have to look at the tests in a little more detail.
