From 783002b9a90dda86f6cd67a85d82840fe8009010 Mon Sep 17 00:00:00 2001 From: Gergely Meszaros <gergely.mesza...@intel.com> Date: Wed, 2 Jul 2025 01:46:03 -0700 Subject: [PATCH] [OpenCL] Add decls for cl_intel_subgroup_local_block_io This extension extends the subgroup block read and write functions defined by `cl_intel_subgroups` (and, when supported, `cl_intel_subgroups_char`, `cl_intel_subgroups_short`, and `cl_intel_subgroups_long`) to support reading from and writing to pointers to the `__local` memory address space in addition to pointers to the `__global` memory address space. It is already supported by the Intel OpenCL compiler.
