_OTbinary anonymousenum _OTbinary: Various types of operators: OTbinary binary OTunary unary OTleaf leaf OTcommut commutative (e1 op e2) == (e2 op e1) (assoc == !=) OTassoc associative (e1 op (e2 op e3)) == ((e1 op e2) op e3) (also commutative) OTassign assignment = op= i++ i-- i=-i str= OTpost post inc or post dec operator OTeop0e if (e op 0) => e OTeop00 if (e op 0) => 0 OTeop1e if (e op 1) => e OTsideff there are side effects to the operator (assign call post ?: && ||) OTconv type conversion operator that could appear on lhs of assignment operator OTlogical logical operator (result is 0 or 1) OTwid high order bits of operation are irrelevant OTopeq an op= operator OTop an operator that has a corresponding op= OTcall function call OTrtol operators that evaluate right subtree first then left OTrel == != < <= > >= operators OTrel2 < <= > >= operators OTdef definition operator (assign call post asm) OTae potential common subexpression operator OTboolnop operation is a nop if boolean result is desired

convidx int convidx(OPER op): Conversion operators. Convert from conversion operator to conversion index parallel array invconvtab[] in cgelem.c
rel_not OPER rel_not(OPER op): Determine things about relational operators.
swaprel (from dmd.backend.cgelem) OPER swaprel(OPER op) via public import dmd.backend.cgelem : swaprel;: Swap relational operators (like if we swapped the leaves).

_rel_integral ubyte[RELMAX] _rel_integral;: If operands are integral types
_rel_not ubyte[RELMAX] _rel_not;: Logical negation
_rel_swap ubyte[RELMAX] _rel_swap;: Operand swap
opcost ubyte[OPMAX] opcost;: Determine the cost of evaluating an operator.
optab1 ubyte[OPMAX] optab1;: Determine properties of an elem. EBIN binary node? EUNA unary node? EOP operator node (unary or binary)? ERTOL right to left evaluation (left to right is default) Eunambig unambiguous definition elem?
