No confirmed encoding conflictsShares encoding space with 1 extension(s)

Show encoding relation details

SHARED_MAJOR_OPCODE: opcode 0x5B — shared major opcode; not a conflict by itself. A true conflict requires overlapping full decode mask/match patterns, including any fixed register/immediate field constraints.
SHARED_CUSTOM_SPACE: both declare custom-2; shared custom space (no per-vendor allocation in RISC-V). Not a conflict on its own — composing both needs opcode remapping or selective enable.

This versioned archive records the Extension's encoding, dependencies, provenance, documentation, and any simulator, toolchain, RTL, test, or hardware support declared by its maintainer.
