Constant Folding and Cross Compilation
In implementing a cross compiler, care must be taken to ensure that the behaviour of the arithmetic operations on the host architecture matches that on the target architecture, as otherwise enabling constant folding will change the behaviour of the program. This is of particular importance in the case of floating point operations, whose precise implementation may vary widely.

Famous quotes containing the words constant, folding, cross and/or compilation:
“There exists a black kingdom which the eyes of man avoid because its landscape fails signally to flatter them. This darkness, which he imagines he can dispense with in describing the light, is error with its unknown characteristics.... Error is certainty’s constant companion. Error is the corollary of evidence. And anything said about truth may equally well be said about error: the delusion will be no greater.”
—Louis Aragon (1897–1982)
“A little sleep, a little slumber, a little folding of the hands to rest, and poverty will come upon you like a robber, and want, like an armed warrior.”
—Bible: Hebrew, Proverbs 6:10.
“If I can cross him any way, I bless myself every way.”
—William Shakespeare (1564–1616)
“The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written.”
—Franklin D. Roosevelt (1882–1945)
