Check whether the number is negative. Note that this doesn't care about the sign flag; it simply looks at the highest bit to determine whether it is s

Returns true if the lookup was ok, or if it failed in a way that allows us to continue looking up in other ways. Returns false if the entire lookup ha

multiply and xor mix function, aka MUM

@returns the list of operands in the concatenation

Splits the current state into separate true / false states.

Constructs an empty path.

Compile *code* and return (compilation, AnalyzedProcedure) for module m.

Quote a shell argument for the current platform shell.

Gets access to the symbol's declared type.

Gets the numeric value of the given decimal digit. If the given character is not a valid decimal digit, the result is undefined.

Indicates whether this is a string type.

in order to detect embedded nulls gracefully, we call this whenever we encounter a null to check whether we really are at the end of the buffer

Allocate @a size bytes of memory with the given @a alignment.

@return a reference to the last element in the array. The array must not be empty!

@return the underlying integer value containing the combined flags.

Performs a multiplication of two unsigned 64-bit integers and returns the result if it does not overflow. If it does, nullopt is returned instead.

@returns an optional expression that calls the class's constructor

Returns the dynamic size of the given type. If mode == Source: "a" is the greatest common divisor of element sizes of all dynamically sized items "b"

Get the number of "active bits". An SVInt might have a large bit width but be set to a very small value, in which case it will have a low number of ac

Gets the index of the symbol within its parent scope, which can be used to determine the relative ordering of scope members.
