| ; Test that emulated TLS uses preferred alignment for variables. |
| ; This fixes a bug where emutls would use lower alignment than expected |
| ; by the code generator, causing crashes with vectorized accesses. |
| ; Fixes https://github.com/llvm/llvm-project/issues/167219 |
| |
| ; A 64-byte array should get 16-byte alignment (preferred for ARM NEON). |
