llvm::APInt::APInt

Synopses

Declared in <llvm/ADT/APInt.h>

Default constructor that creates an APInt with a 1-bit zero value.

explicit
APInt();

Copy constructor.

APInt(APInt const& that);

Move constructor.

APInt(APInt&& that);

Construct an APInt of numBits width, initialized as bigVal[].

APInt(
    unsigned int numBits,
    ArrayRef<uint64_t> bigVal);

Construct an APInt from a string representation.

APInt(
    unsigned int numBits,
    StringRef str,
    uint8_t radix);

Deleted constructor that previously took a raw word pointer.

APInt(
    unsigned int numBits,
    unsigned int numWords,
    uint64_t const bigVal[]) = delete;

Create a new APInt of numBits width, initialized as val.

APInt(
    unsigned int numBits,
    uint64_t val,
    bool isSigned = false,
    bool implicitTrunc = false);

Name	Description
that	Source APInt to copy
numBits	the bit width of the constructed APInt
bigVal	a sequence of words to form the initial value of the APInt
str	the string to be interpreted
radix	the radix to use for the conversion
numWords	Number of words pointed to by `bigVal`
val	the initial value of the APInt
isSigned	how to treat signedness of val
implicitTrunc	allow implicit truncation of non-zero/sign bits of val beyond the range of numBits
