Operations

This page tells you which Operations are currently implemented for each architecture.

• ❌ Means it is not implemented.
• ✅ Means it is implemented.
• ❓ Means 'not applicable'.

Optimized Push/Pop Operations

MultiPush

Architecture	Supported	Notes
x64*	✅
x86*	✅
ARM64	✅	Might fall back to single pop/push if mixing register sizes.

* Implemented but not used, due to more efficient code generation alternative.

MultiPop

Architecture	Supported	Notes
x64*	✅
x86*	✅
ARM64	✅	Might fall back to single pop/push if mixing register sizes.

* Implemented but not used, due to more efficient code generation alternative.
