Section D.6.4

LRM-364

Changes:

Table D-1: Mapping data types

SystemVerilog type	C type
byte	char
shortint	short int
int	int
longint	long long
real	double
shortreal	float
chandle	void*
string	char*

Section D.7.7

LRM-365

Changes:

input arguments, with the exception of open arrays, are passed by value or by reference, depending on the size. ‘Small’ values of formal input arguments are passed by value. The following data types are considered small:

— byte, shortint, int, longint, real, shortreal

— chandle, string

— bit (i.e., 2-state) packed arrays up to 32 bits (canonical representation shall be used, like for a function result; thus a small packed bit array shall be represented as const svBitVec32)

Section D.7.9

LRM-366

Changes:

Types of a function result are restricted to the following SystemVerilog data types (see Table D-1 for the corresponding C type):

— byte, shortint, int, longint, real, shortreal, chandle, string

— packed bit arrays up to 32 bits.
