These indicate how you want arguments / functions to be handled.

Variants

ZExt

Zero-extended before or after call.

SExt

Sign-extended before or after call.

NoReturn

Mark the function as not returning.

InReg

Force argument to be passed in register.

StructRet

Hidden pointer to structure to return.

NoUnwind

Function doesn't unwind stack.

NoAlias

Consider to not alias after call.

ByVal

Pass structure by value.

Nest

Nested function static chain.

ReadNone

Function doesn't access memory.

ReadOnly

Function only reads from memory.

NoInline

Never inline this function.

AlwaysInline

Always inline this function.

OptimizeForSize

Optimize this function for size.

StackProtect

Stack protection.

StackProtectReq

Stack protection required.

Alignment

Alignment of parameter (5 bits) stored as log2 of alignment with +1 bias 0 means unaligned (different from align(1)).

NoCapture

Function creates no aliases of pointer.

NoRedZone

Disable redzone.

NoImplicitFloat

Disable implicit float instructions.

Naked

Naked function.

InlineHint

The source language has marked this function as inline.

StackAlignment

Alignment of stack for function (3 bits) stored as log2 of alignment with +1 bias 0 means unaligned (different from alignstack=(1)).

ReturnsTwice

This function returns twice.

UWTable

Function must be in unwind table.

NonLazyBind

Function is called early/often, so lazy binding isn't effective.

Trait Implementations
