xthead-ba WARNING

PARTIAL_DECODE_OVERLAP: opcode 0x0B funct3 0x1 funct7 null — opcode and funct3 match, but the full mask isn't known (funct7/funct12 not imported). Possible overlap; needs full mask/match data to confirm.
SHARED_CUSTOM_SPACE: both declare custom-0; shared custom space (no per-vendor allocation in RISC-V). Not a conflict on its own — composing both needs opcode remapping or selective enable.
