## Description

This extension relaxes the maxStorageBufferRange limit, allowing more than 4GB to be accessed through a buffer binding (or through a buffer device address). It adds pipeline and shader creation flags that request 64-bit addressing support, and defines which addressing calculations use 64 bits of range.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceShader64BitIndexingFeaturesEXT

## New Enum Constants

- `VK_EXT_SHADER_64BIT_INDEXING_EXTENSION_NAME`

- `VK_EXT_SHADER_64BIT_INDEXING_SPEC_VERSION`

- Extending VkPipelineCreateFlagBits2:

  - `VK_PIPELINE_CREATE_2_64_BIT_INDEXING_BIT_EXT`

- Extending VkShaderCreateFlagBitsEXT:

  - `VK_SHADER_CREATE_64_BIT_INDEXING_BIT_EXT`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_64_BIT_INDEXING_FEATURES_EXT`
