This extension enables C-like structure layout for SPIR-V blocks. It modifies the alignment rules for uniform buffers, storage buffers and push constants, allowing non-scalar types to be aligned solely based on the size of their components, without additional requirements.

Promotion to Vulkan 1.2

Functionality in this extension is included in core Vulkan 1.2, with the EXT suffix omitted. However, if Vulkan 1.2 is supported and this extension is not, the scalarBlockLayout capability is optional. The original type, enum and command names are still available as aliases of the core functionality.
