[kvm-unit-tests PATCH 4/7] svm: change operand to output-only for matching constraint

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



According to GNU extended asm documentation, "the two operands [of
matching constraints] must include one input-only operand and one
output-only operand." So remove the read/write modifier from the output
constraint.
