The issue arises from a mistake in the vector load immediate (VLDI) instruction handling, specifically how the data is being constructed. In the provided code snippet from `insn_trans/trans_vec.c.inc`, the case for `case 1:` incorrectly computes the `data` value as `(t << 24) | (t << 8)`. This results in an incorrect pattern of bytes being replicated across the vector, leading to unexpected output when running the test program under QEMU. + +The correct computation should be `(t << (8+32)) | (t << 8)` to properly replicate the immediate value across all lanes. The problem is isolated to the instruction translation and execution within QEMU's emulation of LoongArch64 instructions, specifically the `xvldi` instruction. + +### Bug Classification +The issue pertains to an error in handling a specific instruction (`xvldi`) during its translation and execution in QEMU. This makes it fall under the category related to faulty instruction implementation. + +**Category:** instruction \ No newline at end of file |
