36 | * Vector optional opcode tracking. | |
37 | * Except for the basic logical operations (and, or, xor), and | |
38 | * data movement (mov, ld, st, dupi), many vector opcodes are | |
39 | * optional and may not be supported on the host. Thank Intel | |
40 | * for the irregularity in their instruction set. | |
41 | * | |
42 | * The gvec expanders allow custom vector operations to be composed, | |
43 | * generally via the .fniv callback in the GVecGen* structures. At | |
44 | * the same time, in deciding whether to use this hook we need to | |
45 | * know if the host supports the required operations. This is | |
46 | * presented as an array of opcodes, terminated by 0. Each opcode | |
47 | * is assumed to be expanded with the given VECE. | |
48 | * | |
49 | * For debugging, we want to validate this array. Therefore, when | |
50 | * tcg_ctx->vec_opt_opc is non-NULL, the tcg_gen_*_vec expanders | |
51 | * will validate that their opcode is present in the list. | |
