However, there is a comma instead of # semicolon to end the dialect assignment, meaning that the opcode # assignment only happens in the if statement. Properly terminate that # line so that Clang no longer warns. # # Fixes: 5b102782c7f4 ("powerpc/xmon: Enable disassembly files (compilation changes)") # Signed-off-by: Nathan Chancellor # Reviewed-by:
