Struct FastMathFlags 

pub struct FastMathFlags { /* private fields */ }

Floating-point fast-math flags (#arith.fastmath).

Each flag relaxes IEEE-754 semantics to permit additional optimization.

Implementations

impl FastMathFlags

pub const NAME: &'static str = "fastmath"

Upstream MLIR attribute mnemonic, without the dialect prefix.

pub const NONE: Self

No flags set.

pub const REASSOC: Self

Allow reassociation.

pub const NNAN: Self

Assume no NaN operands or results.

pub const NINF: Self

Assume no infinite operands or results.

pub const NSZ: Self

Ignore the sign of zero.

pub const ARCP: Self

Allow reciprocal approximation.

pub const CONTRACT: Self

Allow floating-point contraction such as fused multiply-add.

pub const AFN: Self

Allow approximate library functions.

pub const fn bits(self) -> u8

Returns the raw bit mask, matching MLIR’s encoding.

pub const fn from_bits(bits: u8) -> Option<Self>

Creates a set from a raw mask, rejecting undefined bits.

pub const fn is_none(self) -> bool

Returns whether no flags are set.

pub const fn contains(self, other: Self) -> bool

Returns whether every flag in other is set.

pub const fn union(self, other: Self) -> Self

Returns the union of two sets.

pub fn mlir_spelling(self) -> String

Returns the comma-separated MLIR spelling, or none.

impl FastMathFlags

pub const FAST: Self

Every fast-math flag (fast).
