Struct cretonne_codegen::ir::AbiParam
[−]
[src]
pub struct AbiParam { pub value_type: Type, pub purpose: ArgumentPurpose, pub extension: ArgumentExtension, pub location: ArgumentLoc, }
Function parameter or return value descriptor.
This describes the value type being passed to or from a function along with flags that affect how the argument is passed.
Fields
value_type: Type
Type of the argument value.
purpose: ArgumentPurpose
Special purpose of argument, or Normal
.
extension: ArgumentExtension
Method for extending argument to a full register.
location: ArgumentLoc
ABI-specific location of this argument, or Unassigned
for arguments that have not yet
been legalized.
Methods
impl AbiParam
[src]
pub fn new(vt: Type) -> Self
[src]

pub fn special_reg(vt: Type, purpose: ArgumentPurpose, regunit: RegUnit) -> Self
[src]

pub fn uext(self) -> Self
[src]
Convert self
to a parameter with the uext
flag set.
pub fn sext(self) -> Self
[src]
Convert self
to a parameter type with the sext
flag set.
pub fn display<'a, R: Into<Option<&'a RegInfo>>>(
&'a self,
regs: R
) -> DisplayAbiParam<'a>
[src]
&'a self,
regs: R
) -> DisplayAbiParam<'a>
Return an object that can display self
with correct register names.
