Examples with Fold org.graalvm.compiler.api.replacements.Fold used on opensource projects

Example 1 with Fold

use of org.graalvm.compiler.api.replacements.Fold in project graal by oracle.

the class UnalignedHeapChunkMemoryWalkerAccessFeature method getCardTableSize.

/**
 * How big is the card table?
 */
@Fold
static UnsignedWord getCardTableSize() {
    // A "table" of one entry.
    final UnsignedWord requiredSize = CardTable.tableSizeForMemorySize(WordFactory.unsigned(1));
    final UnsignedWord alignment = WordFactory.unsigned(ConfigurationValues.getObjectLayout().getAlignment());
    return UnsignedUtils.roundUp(requiredSize, alignment);
}

Example 2 with Fold

use of org.graalvm.compiler.api.replacements.Fold in project graal by oracle.

the class UnalignedHeapChunkMemoryWalkerAccessFeature method getObjectStartOffset.

/**
 * Where does the Object start?
 */
@Fold
static UnsignedWord getObjectStartOffset() {
    final UnsignedWord cardTableLimitOffset = getCardTableLimitOffset();
    final UnsignedWord alignment = WordFactory.unsigned(ConfigurationValues.getObjectLayout().getAlignment());
    final UnsignedWord result = UnsignedUtils.roundUp(cardTableLimitOffset, alignment);
    return result;
}

Example 3 with Fold

use of org.graalvm.compiler.api.replacements.Fold in project graal by oracle.

the class AlignedHeapChunkMemoryWalkerAccessFeature method getFirstObjectTableStartOffset.

/**
 * Where does the first object table start?
 */
@Fold
static UnsignedWord getFirstObjectTableStartOffset() {
    /* The first object table starts at the end of the card remembered set table. */
    final UnsignedWord cardTableLimit = getCardTableLimitOffset();

    return UnsignedUtils.roundUp(cardTableLimit, alignment);
}

Example 4 with Fold

use of org.graalvm.compiler.api.replacements.Fold in project graal by oracle.

/**
 * How big is the first object table?
 */
@Fold
