Start with tests/test_tpsv.py, especially test_accuracy_ctpsv_stride and its _run helper, then inspect src/flag_blas/ops/level2/tpsv.py at _complex_tpsv and ctpsv. Reproduce with pytest tests/test_tpsv.py in the Hygon DTK environment and determine why Triton compilation segfaults. Done means the test completes without a segmentation fault and the accuracy suite passes on Hygon.
