The following asm statements generated a sparse warning: asm("addcc \n\t" : "=r" (((USItype)(r2))) warning: asm output is not an lvalue When asking on the sparse mailing list Linus replyed: " Those casts to (USItype) are all pointless to begin with (since the values are of that type already!) and they mean that the expression isn't something you can assign to (lvalue). " In the math emulation code drop all casts in the output parts of the asm statements. This fixes a lot of "warning: asm output is not an lvalue" sparse warnings in math_64.c.
