POLARDUPABLEXPR(3) ABL FUNCTIONS POLARDUPABLEXPR(3) NAME polardupablexpr - duplicates an expression and moves down the inverters. SYNOPSIS #include "abl101.h" chain_list *polardupablexpr( Expr, Polar ) chain_list *Expr; int Polar; PARAMETERS Expr Expression to modify. Polar Expression polarity. DESCRIPTION polardupablexpr modifies Expr by moving down the inverters to the atomic level. polardupablexpr applies the Morgan's laws. If Polar is equal to ABL_POLAR_NEGATIVE the function returns the modified expression after hav- ing complemented it. RETURN VALUE polardupablexpr returns the modified expression. EXAMPLE #include "abl101.h" chain_list *Expr1; chain_list *Expr2; Expr1 = createabloper( ABL_NOT ); Expr2 = createabloper( ABL_NOT ); addablhexpr( Expr1, createablatom( "a" ) ); addablhexpr( Expr2, Expr1 ); Expr1 = polardupablexpr( Expr2, ABL_POLAR_POSITIVE ); /* displays a */ viewablexpr( Expr1, ABL_VIEW_VHDL ); SEE ALSO abl(1) ASIM/LIP6 October 1, 1997 POLARDUPABLEXPR(3)
