Description

This extension adds support for new SPIR-V shader instructions that allow loading and storing a cooperative matrix without needing to stage through shared memory and to allow bit casting arrays.

These instructions are defined by the SPV_QCOM_cooperative_matrix_conversion SPIR-V extension and can be used with the GLSL_QCOM_cooperative_matrix_conversion GLSL extension.
