  "message": "Fix Hexagon ABI calling convention for small aggregates\n\nSmall structs (\u003c\u003d 64 bits) were being passed with their fields split\ninto separate arguments instead of being packed into register-sized\nchunks. This caused ABI mismatches.\n\nThe fix properly casts small aggregates to consecutive register-sized\nchunks using Uniform::consecutive(), matching the Hexagon C ABI where\nsmall structs are packed into R1:0 register pair.\n\nThis fixes tests like extern-pass-TwoU16s.rs and extern-pass-TwoU8s.rs.\n",
