Dependencies
This extension is written against the SPIR-V Specification Version 1.5, Revision 2.
Overview
This extension relaxes the restriction that OpTypeInt must have a width of 32 bits.
Ints of arbitrary bit widths can be beneficial on targets that can exploit narrower widths such as FPGAs.
Extension Name
To use this extension within a SPIR-V module, the following OpExtension must be present in the module:
OpExtension "SPV_INTEL_arbitrary_precision_integers"
New Capabilities
This extension introduces a new capability:
ArbitraryPrecisionIntegersINTEL
Token Number Assignments

5844 |
Modifications to the SPIR-V Specification Version 1.5
Capability
Modify Section 3.31, Capability, adding a row to the Capability table:
| Capability | Implicitly Declares | |
|---|---|---|
5844 |
ArbitraryPrecisionIntegersINTEL Allows the use of the OpTypeInt to declare integers of any arbitrary width. The minimum requirement is that all bitwidths up to 32-bits must be supported, but implementations can extend the support beyond 32-bits. |
Int8, Int16 |
Validation Rules
None.
Issues
None.
