structure Lean.Meta.Simp.BuiltinSimprocs : Type

Builtin simproc declaration extension state.

It contains:

• The discrimination tree keys for each simproc (including symbolic evaluation procedures) name.
• The actual procedure associated with a name.

• keys : Std.HashMap Name (Array SimpTheoremKey)
• procs : Std.HashMap Name (Simproc ⊕ DSimproc)

instance Lean.Meta.Simp.instInhabitedBuiltinSimprocs : Inhabited BuiltinSimprocs

Equations

• Lean.Meta.Simp.instInhabitedBuiltinSimprocs = { default := { keys := default, procs := default } }

opaque Lean.Meta.Simp.builtinSimprocDeclsRef : IO.Ref BuiltinSimprocs

This global reference is populated using the command builtin_simproc_pattern%.

This reference is then used to process the attributes builtin_simproc and builtin_sevalproc. Both attributes need the keys and the actual procedure registered using the command builtin_simproc_pattern%.

Try to retrieve the simproc set using the simp or simproc attribute names. Recall that when we declare a simp set using register_simp_attr, an associated simproc set is automatically created. We use the function simpAttrNameToSimprocAttrName to find the simproc associated with the simp attribute.
