  "message": "Starting support for HAL dispatch specialization. (#12483)\n\nThis allows `stream.cmd.dispatch` ops to specify multiple entry points\r\nin executables that can be dispatched. During interface materialization\r\nthe entry points are expanded for all materialized variants. HAL\r\nbackends are also able to add their own entry points either in existing\r\nvariants or new ones during translation (no helpers yet, but it\u0027s\r\npossible). When lowering the `stream.cmd.dispatch` into\r\n`hal.command_buffer.dispatch` each export now chooses the condition for\r\nwhich it should be selected.\r\n\r\nThis initial work just prepares the op for this conditional dispatch and\r\nalso solves an issue with compiler reentrancy where between interface\r\nmaterialization and HAL conversion we had IR that would not verify\r\n(stream ops still referencing un-materialized exports). Only the\r\nexisting target variant matcher condition is supported but we now have\r\nthe place where we\u0027d call out to HAL backend-produced logic for\r\nselection (`getExportConditionAttr`).\r\n\r\nThe `inline-dynamic` HAL model can support this too but for now that\u0027s\r\ndeferred until we add the backend support - the `hal.device.switch` op\r\nneeds a reworking to be used in that context.\r\n\r\nFixes #12476.",
