Examples with ConditionFlag org.graalvm.compiler.asm.aarch64.AArch64Assembler.ConditionFlag used on opensource projects

Example 1 with ConditionFlag

use of org.graalvm.compiler.asm.aarch64.AArch64Assembler.ConditionFlag in project graal by oracle.

the class AArch64LIRGenerator method emitCompareBranch.

@Override
public void emitCompareBranch(PlatformKind cmpKind, Value left, Value right, Condition cond, boolean unorderedIsTrue, LabelRef trueDestination, LabelRef falseDestination, double trueDestinationProbability) {
    boolean mirrored = emitCompare(cmpKind, left, right, cond, unorderedIsTrue);
    Condition finalCondition = mirrored ? cond.mirror() : cond;
    boolean finalUnorderedIsTrue = mirrored ? !unorderedIsTrue : unorderedIsTrue;
    ConditionFlag cmpCondition = toConditionFlag(((AArch64Kind) cmpKind).isInteger(), finalCondition, finalUnorderedIsTrue);
    append(new BranchOp(cmpCondition, trueDestination, falseDestination, trueDestinationProbability));
}

Example 2 with ConditionFlag

use of org.graalvm.compiler.asm.aarch64.AArch64Assembler.ConditionFlag in project graal by oracle.

the class AArch64LIRGenerator method emitConditionalMove.

/**
 * Conditionally move trueValue into new variable if cond + unorderedIsTrue is true, else
 * falseValue.
 *
 * @param left Arbitrary value. Has to have same type as right. Non null.
 * @param right Arbitrary value. Has to have same type as left. Non null.
 * @param cond condition that decides whether to move trueValue or falseValue into result. Non
 *            null.
 * @param unorderedIsTrue defines whether floating-point comparisons consider unordered true or
 *            not. Ignored for integer comparisons.
 * @param trueValue arbitrary value same type as falseValue. Non null.
 * @param falseValue arbitrary value same type as trueValue. Non null.
 * @return value containing trueValue if cond + unorderedIsTrue is true, else falseValue. Non
 *         null.
