LLVM ERROR: Error while trying to spill R14D from class ADDR64Bit: Cannot scavenge register without an emergency spill slot!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
Stack dump:
0. Program arguments: ./bin/llc -mtriple=s390x-linux-gnu -mcpu=z16 ./tc_regscav.ll -misched=shuffle
1. Running pass 'Function Pass Manager' on module './tc_regscav.ll'.
2. Running pass 'Prologue/Epilogue Insertion & Frame Finalization' on function '@fun'
@uweigand This test case has i128 registers, but it is an ADDR64 that needs scavenging...
