Detailed Description

Value representation used for compile-time evaluation of bitstring expressions. A bit is either:

• '0' : zero
• '1' : one
• 'D' : defined, but unknown
• 'X' : undefined and unknown

create()

static BitValueRepresentation jlm::rvsdg::BitValueRepresentation::create ( const std::vector< BitValueRepresentation > &  bitValues )

inlinestatic

Creates a BitValueRepresentation from a vector of BitValueRepresentations by concatenating the input representations. The number of bits of the result representation is the sum of the number of bits of the input representations.

Parameters

bitValues

A vector of input representations

Returns

The concatenation of the input representations.

Precondition

The method expects at least a single element in bitValues.
