Struct rustc_target::abi::call::Uniform
source · pub struct Uniform {
pub unit: Reg,
pub total: Size,
pub is_consecutive: bool,
}
Expand description
An argument passed entirely registers with the same kind (e.g., HFA / HVA on PPC64 and AArch64).
Fields§
§unit: Reg
§total: Size
The total size of the argument, which can be:
- equal to
unit.size
(one scalar/vector), - a multiple of
unit.size
(an array of scalar/vectors), - if
unit.kind
isInteger
, the last element can be shorter, i.e.,{ i64, i64, i32 }
for 64-bit integers with a total size of 20 bytes. When the argument is actually passed, this size will be rounded up to the nearest multiple ofunit.size
.
is_consecutive: bool
Indicate that the argument is consecutive, in the sense that either all values need to be passed in register, or all on the stack. If they are passed on the stack, there should be no additional padding between elements.
Implementations§
source§impl Uniform
impl Uniform
pub fn align<C: HasDataLayout>(&self, cx: &C) -> Align
sourcepub fn new(unit: Reg, total: Size) -> Self
pub fn new(unit: Reg, total: Size) -> Self
Pass using one or more values of the given type, without requiring them to be consecutive. That is, some values may be passed in register and some on the stack.
sourcepub fn consecutive(unit: Reg, total: Size) -> Self
pub fn consecutive(unit: Reg, total: Size) -> Self
Pass using one or more consecutive values of the given type. Either all values will be passed in registers, or all on the stack.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
