Example 1 with Condition

use of org.robovm.compiler.llvm.Icmp.Condition in project robovm by robovm.

the class MethodCompiler method if_.

private void if_(IfStmt stmt) {
    ConditionExpr condition = (ConditionExpr) stmt.getCondition();
    Value op1 = immediate(stmt, (Immediate) condition.getOp1());
    Value op2 = immediate(stmt, (Immediate) condition.getOp2());
    Icmp.Condition c = null;
