  "message": "Enable e2e `linalg_ext.pack` test on VMVX + ukernel (#10798)\n\nThis is in preparation for actually writing a microkernel.\r\n\r\nThis is only pack for now, not unpack, because of\r\nhttps://github.com/iree-org/iree/issues/10796 .\r\n\r\nI had to introduce a new compiler command-line flag,\r\n`--iree-vmvx-enable-microkernels-decompose-linalg-generic`, defaulting\r\nto `true` (the current behavior), so that I could set it to `false` in\r\nthis test. The problem is that when `--iree-vmvx-enable-microkernels` is\r\npassed, we use a DecomposeLinalgGenericPass. The `pack.mlir` test here\r\ncontains `linalg.generic` which, when decomposed by this pass, are split\r\ninto a chain of multiple `linalg.generic` with temporary buffers in\r\nbetween. These temporary buffers are `memref.alloca` in the IR,\r\nresulting in compilation failures:\r\n\r\n```\r\nerror: failed to legalize operation \u0027memref.alloca\u0027 that was explicitly marked illegal\r\n```",
