# Test defends that if all instructions are skipped leaving an empty input, an error is printed.

bzhi %eax, %ebx, %ecx

# CHECK-ALL-NOT: error

# CHECK-ERROR: error: found an unsupported instruction in the input assembly sequence, use -skip-unsupported-instructions=lack-sched to ignore these on the input.

# CHECK-SKIP: warning: found an unsupported instruction in the input assembly sequence, skipping with -skip-unsupported-instructions, note accuracy will be impacted:
# CHECK-SKIP: note: instruction:      bzhil   %eax, %ebx, %ecx
# CHECK-SKIP: error: no assembly instructions found.
