Documentation

Instrinsics are special symbols builtin to the compiler. They are all either begin with an @ or are part of a builtin module (which itself begins with an @).

Intrinsic functions are almost always inlined and some (such as type trait intrinsics) don't have any runtime execution at all. As such, you cannot take the address of an intrinsic function.

Intrinsic Functions

Importing

@import	Import a Panther file
@importC	Import a C file
@importCpp	Import a C++ file

Operational

@abort	Abort the program
@breakpoint	Cause an execution trap to request the debugger break execution
@makeInitPtr	Converts an uninitialized-qualified pointer to a pointer

Intrinsic functions for Internal Use

These intrinsic functions are meant for internal use by the standard library. All functionality of these functions can be found in the standard library and/or in the language itself.

Atomic

@atomicLoad	Atomically load a value
@atomicStore	Atomically store a value
@atomicRMW	Atomic read-modify-write
@cmpxchg	Atomic compare-exchange

Arithmetic

@add	Integer addition
@addWrap	Integer addition that returns if operation wrapped
@addSat	Integer saturating addition
@fadd	Floating-point addition
@sub	Integer subtraction
@subWrap	Integer subtraction that returns if operation wrapped
@subSat	Integer saturating subtraction
@fsub	Floating-point subtraction
@mul	Integer multiplication
@mulWrap	Integer multiplication that returns if operation wrapped
@mulSat	Integer saturating multiplication
@fmul	Floating-point multiplication
@div	Integer division
@fdiv	Floating-point division
@rem	Division remainder
@fneg	Floating-point negation

Bitwise

@and	Bitwise and
@or	Bitwise or
@xor	Bitwise xor
@shl	Bitwise shift left
@shlSat	Bitwise saturating shift left
@shr	Bitwise saturating shift left
@bitReverse	Reverse the bits
@byteSwap	Swap the bytes
@ctPop	Count the number of one bits
@ctlz	Count the number of leading zero bits
@cttz	Count the number of trailing zero bits

Comparative

@eq	Calculate equality
@neq	Calculate non-equality
@lt	Calculate less than
@lte	Calculate less than or equal to
@gt	Calculate greater than
@gte	Calculate greater than or equal to

Type Conversion

@bitCast	Bitwise convert a value of any type to any other tpe of the same size
@trunc	Truncate any integral type to any other smaller integral type
@ftrunc	Truncate any floating-point type to any other smaller floating-point type
@sext	Sign extend any integral type to any other larger integral type
@zext	Zero extend any integral type to any other larger integral type
@fext	Extend any floating-point type to any other larger floating-point type
@iToF	Convert any integral type to any floating-point type
@fToI	Convert any floating-point type to any integral type

Type Traits

@getTypeID	Get the TypeID of a type
@arrayElementTypeID	Get the TypeID of the elements of an array type
@arrayRefElementTypeID	Get the TypeID of the elements of an array reference type
@numBytes	Get the number of bytes of TypeID
@numBits	Get the number of bits of TypeID

Intrinsic modules for Internal Use

These intrinsic modules contain types that are helpers for intrinsics meant for internal use by the standard library.
