2011-01-18Lower the maximum arity from 256 to 255Björn Gustavsson
Historically, for no good reason, a function is allowed to have from 0 to 256 arguments. Thus, the number of arguments *almost* fits into a byte. HiPE only supports up to 255 arguments (because it assumes that the function arity fits into a single byte), and fixing that limitation would require ugly special-case handling. In Dialyzer, the arity type is defined to be a byte (i.e. 0..255). Since no-one uses functions with 256 arguments anyway, lower the limit to 255.
