NIR ALU Instructions

ALU instructions represent simple operations, such as addition, multiplication, comparison, etc., that take a certain number of arguments and return a result that only depends on the arguments. ALU instructions in NIR must be pure in the sense that they have no side effect and that identical inputs yields an identical output. A good rule of thumb is that only things which can be constant folded should be ALU operations. If it can’t be constant folded, then it should probably be an intrinsic instead.

Each ALU instruction has an opcode, which is a member of the nir_op enum, that describes what it does as well as how many arguments it takes. Associated with each opcode is an metadata structure, nir_op_info, which shows how many arguments the opcode takes, information about data types, and algebraic properties such as associativity and commutativity. The info structure for each opcode may be accessed through a global nir_op_infos array that’s indexed by the opcode.

ALU operations are typeless, meaning that they’re only defined to convert a certain bit-pattern input to another bit-pattern output. The only concrete notion of types for a NIR SSA value or register is that each value has a number of vector components and a bit-size. How that data is interpreted is entirely controlled by the opcode. NIR doesn’t have opcodes for intBitsToFloat() and friends because they are implicit.

Even though ALU operations are typeless, each opcode also has an “ALU type” metadata for each of the sources and the destination which can be floating-point, boolean, integer, or unsigned integer. The ALU type mainly helps back-ends which want to handle all conversion instructions, for instance, in a single switch case. They’re also important when a back-end requests the absolute value, negate, and saturate modifiers (not used by core NIR). In that case, modifiers are interpreted with respect to the ALU type on the source or destination of the instruction. In addition, if an operation takes a boolean argument, then the argument may be assumed to be either 0 for false or ~0 (a.k.a -1) for true even if it is not a 1-bit value. If an operation’s result has a boolean type, then it may only produce only 0 or ~0.

Most of the common ALU ops in NIR operate per-component, meaning that the operation is defined by what it does on a single scalar value and, when performed on vectors, it performs the same operation on each component. Things like add, multiply, etc. fall into this category. Per-component operations naturally scale to as many components as necessary. Non-per-component ALU ops are things like vec4 or pack_64_2x32 where any given component in the result value may be a combination of any component in any source. These ops have a number of destination components and a number of components required by each source which is fixed by the opcode.

While most instruction types in NIR require vector sizes to perfectly match on inputs and outputs, ALU instruction sources have an additional nir_alu_src.swizzle field which allows them to act on vectors which are not the native vector size of the instruction. This is ideal for hardware with a native data type of vec4 but also means that ALU instructions are often used (and required) for packing/unpacking vectors for use in other instruction types like intrinsics or texture ops.

struct nir_op_info
const char *name

Name of the NIR ALU opcode

uint8_t num_inputs

Number of inputs (sources)

uint8_t output_size

The number of components in the output

If non-zero, this is the size of the output and input sizes are explicitly given; swizzle and writemask are still in effect, but if the output component is masked out, then the input component may still be in use.

If zero, the opcode acts in the standard, per-component manner; the operation is performed on each component (except the ones that are masked out) with the input being taken from the input swizzle for that component.

The size of some of the inputs may be given (i.e. non-zero) even though output_size is zero; in that case, the inputs with a zero size act per-component, while the inputs with non-zero size don’t.

nir_alu_type output_type

The type of vector that the instruction outputs.

uint8_t input_sizes[NIR_ALU_MAX_INPUTS]

The number of components in each input

See nir_op_infos::output_size for more detail about the relationship between input and output sizes.

nir_alu_type input_types[NIR_ALU_MAX_INPUTS]

The type of vector that each input takes.

nir_op_algebraic_property algebraic_properties

Algebraic properties of this opcode

bool is_conversion

Whether this represents a numeric conversion opcode

extern const nir_op_info nir_op_infos[nir_num_opcodes]

Metadata for each nir_op, indexed by opcode

struct nir_alu_instr
nir_instr instr

Base instruction

nir_op op

Opcode

bool exact

Indicates that this ALU instruction generates an exact value

This is kind of a mixture of GLSL “precise” and “invariant” and not really equivalent to either. This indicates that the value generated by this operation is high-precision and any code transformations that touch it must ensure that the resulting value is bit-for-bit identical to the original.

bool no_signed_wrap

Indicates that this instruction doese not cause signed integer wrapping to occur, in the form of overflow or underflow.

bool no_unsigned_wrap

Indicates that this instruction does not cause unsigned integer wrapping to occur, in the form of overflow or underflow.

uint32_t fp_fast_math

The float controls bit float_controls2 cares about. That is, NAN/INF/SIGNED_ZERO_PRESERVE only. Allow{Contract,Reassoc,Transform} are still handled through the exact bit, and the other float controls bits (rounding mode and denorm handling) remain in the execution mode only.

nir_def def

Destination

nir_alu_src src[]

Sources

The size of the array is given by nir_op_info.num_inputs.

struct nir_alu_src
nir_src src

Base source

uint8_t swizzle[NIR_MAX_VEC_COMPONENTS]

For each input component, says which component of the register it is chosen from.

Note that which elements of the swizzle are used and which are ignored are based on the write mask for most opcodes - for example, a statement like “foo.xzw = bar.zyx” would have a writemask of 1101b and a swizzle of {2, 1, x, 0} where x means “don’t care.”

Description: Roughly implements the OpenGL / Vulkan rules for sign(float). The GLSL.std.450 FSign instruction is defined as:

Result is 1.0 if x > 0, 0.0 if x = 0, or -1.0 if x < 0.

If the source is equal to zero, there is a preference for the result to have the same sign, but this is not required (it is required by OpenCL). If the source is not a number, there is a preference for the result to be +0.0, but this is not required (it is required by OpenCL). If the source is not a number, and the result is not +0.0, the result should definitely not be NaN.

The values returned for constant folding match the behavior required by OpenCL.
