The user is reporting an assertion error in QEMU after updating to version 5.2.0. The error is related to the TCG (Tiny Code Generator) component, specifically in the file tcg-op-gvec.c. The assertion failure is checking that (maxsz & max_align) == 0, which isn't the case when maxsz is 56. + +The user mentions that a specific commit (e2e7168a214b...) introduced this change. Before the commit, the code checked if maxsz was divisible by 8, but after the change, it's checking for alignment with max_align, which is calculated based on whether maxsz is >=16. For maxsz=56, the calculation of max_align would be 15 (since 56 >=16), and 56 & 15 is 8, not zero, hence the assertion failure. + +Looking at the backtrace, the error occurs during the generation of a vector move operation (tcg_gen_gvec_mov) which is part of translating an ARM64 instruction (handle_fpfpcvt). This seems to be during the execution of a specific instruction that involves moving or clearing vector registers. + +The problem arises because the code now enforces a stricter alignment check. The function simd_desc is generating a descriptor for a SIMD operation, and the size (56 bytes) isn't aligned properly according to the new check. This is likely due to an instruction expecting a certain vector size that doesn't meet the new alignment constraints introduced by the commit. + +Since the error is triggered by the execution of a specific instruction (as seen in the backtrace, like handle_fpfpcvt and disas_fp_int_conv), it's related to how QEMU is handling that particular instruction's translation. Therefore, this should be classified under the 'instruction' category because the issue stems from the incorrect handling or translation of an instruction leading to the assertion failure. +</think> + +instruction \ No newline at end of file |
