This extension is written against Revision 1 of the version 1.1 of the SPIR-V Specification.

The extension is written against Revision 1 of the OpenGL extension AMD_gpu_shader_int16.

This extension is written to provide the functionality of the AMD_gpu_shader_int16, OpenGL Shading Language Specification extension, for SPIR-V.

This extension introduces 16-bit signed and unsigned integer support to extended instructions described in the GLSL.std.450 extended instruction set.

To enable SPV_AMD_gpu_shader_int16 extension in SPIR-V, use

This extension adds support for 16-bit signed and unsigned integer component types for the following instructions described in the GLSL.std.450 extended instruction set:

Modify OpSpecConstantOp definition:

(Append OpUConvert to the list of permitted ..Convert Opcodes):

Opcode must be one of the following opcodes. This literal operand is limited to a single word.

OpSConvert, OpFConvert, OpUConvert, (..)

Modify Section 2, Binary Form
