Struct rustc_codegen_llvm::abi::CastTarget
source · pub(crate) struct CastTarget {
pub prefix: [Option<Reg>; 8],
pub rest: Uniform,
pub attrs: ArgAttributes,
}
Expand description
Describes the type used for PassMode::Cast
.
Passing arguments in this mode works as follows: the registers in the prefix
(the ones that
are Some
) get laid out one after the other (using repr(C)
layout rules). Then the
rest.unit
register type gets repeated often enough to cover rest.size
. This describes the
actual type used for the call; the Rust type of the argument is then transmuted to this ABI type
(and all data in the padding between the registers is dropped).
Fields§
§prefix: [Option<Reg>; 8]
§rest: Uniform
§attrs: ArgAttributes
Implementations§
source§impl CastTarget
impl CastTarget
pub fn pair(a: Reg, b: Reg) -> CastTarget
sourcepub fn unaligned_size<C>(&self, _cx: &C) -> Sizewhere
C: HasDataLayout,
pub fn unaligned_size<C>(&self, _cx: &C) -> Sizewhere
C: HasDataLayout,
When you only access the range containing valid data, you can use this unaligned size;
otherwise, use the safer size
method.
pub fn size<C>(&self, cx: &C) -> Sizewhere
C: HasDataLayout,
pub fn align<C>(&self, cx: &C) -> Alignwhere
C: HasDataLayout,
sourcepub fn eq_abi(&self, other: &CastTarget) -> bool
pub fn eq_abi(&self, other: &CastTarget) -> bool
Checks if these two CastTarget
are equal enough to be considered “the same for all
function call ABIs”.

something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it.source§impl<Q, K> Equivalent<K> for Q

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.
