  Adding comments
# specification of operators for MidIL version of the IR.  Each line (other than comments)
# specifies an operator using four fields, which are separated by ":".  The fields are
#	name
#	argument type		(optional)
#	arity
#	comment			(optional)
#
# type-indexed arithmetic operations

### vector operations
# Dot<ty>(u, v)	-- computes dot product of u and v; ty specifies u and v's type
Dot : ty : 2 :
# Cross(u, v)	-- computes cross product of u and v
Cross : : 2 :
# Select<i>(u)  -- select ith element of vector u
Select : int : 1 :
# Norm<ty>(u)   -- computes length of vector u; ty specifies u's type
Norm : ty : 1 :
# Scale<ty>(s,u) -- multiply scalar s time vector u; ty specifies u's type
Scale : ty : 2 : scalar*vector multiplication
# IncScale<ty>(s,u) -- divide vector u by scalar s; ty specifies u's type
InvScale : ty : 2 : vector/scalar division
CL : : 1 : linear anisotropy measures
PrincipleEvec : ty : 2 : principle eigenvector; ty is result vector type
Subscript : ty : 2 : 
Floor : int : 1 : compute real floor of a vector
