Dependencies

+
+
+

This extension is written against the SPIR-V Specification, +Version 1.5, Revision 3, Unified

+
+
+

This extension is written against the OpenCL Extended Instruction Set +Specification, Version 1.00, Revision 7

+
+
+

This extension requires SPIR-V 1.0.

+
+
+
+
+

Overview

+
+
+

This extension relaxes the address space requirement of the printf builtin +to support the cl_ext_relaxed_printf_string_address_space OpenCL C extension.

+
+
+
+
+

Extension Name

+
+
+

To use this extension within a SPIR-V module, the following +OpExtension must be present in the module:

+
+
+
+
OpExtension "SPV_EXT_relaxed_printf_string_address_space"
+
+
+
+
+
+

Modifications to the OpenCL Extended Instruction Set Specification, Version 1.00, Revision 4

+
+
+

Modify Section 2.8, "Misc instructions", the printf description, the +sentence "format must be a pointer(constant) to i8." to +"format must be a pointer(constant, global, local, private, generic) to i8."

+
+
+

Issues

+
+

None
