Function subgroup_inverse_ballot

pub unsafe fn subgroup_inverse_ballot(value: SubgroupMask) -> bool

Evaluates a value for all active invocations in the group, resulting in true if the bit in value for the corresponding invocation is set to one, otherwise the result is false.

Result Type must be a Boolean type.

Execution is a Scope that identifies the group of invocations affected by this command. It must be Subgroup.

value must be a vector of four components of integer type scalar, whose Width operand is 32 and whose Signedness operand is 0.

Behavior is undefined unless value is the same for all invocations that execute the same dynamic instance of this instruction.

value is a set of bitfields where the first invocation is represented in the lowest bit of the first vector component and the last (up to the size of the group) is the higher bit number of the last bitmask needed to represent all bits of the group invocations.

Requires Capability GroupNonUniformBallot.

Safety

• value must be the same for all dynamic instances of this instruction
