* [BugFix] Skip DecoupleTypeCast on Evaluate roots to keep cp.async operands in their address spaces
* [Test] Assert cp_async_gs lines exist before checking their operands
The codegen regression test filtered kernel source with
, so a source with no global->shared calls
left the operand assertion with nothing to inspect and the test passed
vacuously. The preceding did not catch
that: cp_async_commit/cp_async_wait come from the pipeline's sync
skeleton, a separate emit site, and match that substring on their own.
Collect the cp_async_gs lines, assert the collection is non-empty, then
check each one for _local_cast operands.
