- * The {@code JMM_*} constants capture the memory barriers necessary to implement the Java Memory - * Model with respect to volatile field accesses. Their values are explained by this comment from - * templateTable_i486.cpp in the HotSpot source code: - * - * 

- * Volatile variables demand their effects be made known to all CPU's in
- * order.  Store buffers on most chips allow reads & writes to reorder; the
- * JMM's ReadAfterWrite.java test fails in -Xint mode without some kind of
- * memory barrier (i.e., it's not sufficient that the interpreter does not
- * reorder volatile references, the hardware also must not reorder them).
- *
- * According to the new Java Memory Model (JMM):
- * (1) All volatiles are serialized wrt to each other.
- * ALSO reads & writes act as acquire & release, so:
- * (2) A read cannot let unrelated NON-volatile memory refs that happen after
- * the read float up to before the read.  It's OK for non-volatile memory refs
- * that happen before the volatile read to float down below it.
- * (3) Similarly, a volatile write cannot let unrelated NON-volatile memory refs
- * that happen BEFORE the write float down to after the write.  It's OK for
- * non-volatile memory refs that happen after the volatile write to float up
- * before it.
- *
- * We only put in barriers around volatile refs (they are expensive), not
- * _between_ memory refs (which would require us to track the flavor of the
- * previous memory refs).  Requirements (2) and (3) require some barriers
- * before volatile stores and after volatile loads.  These nearly cover
- * requirement (1) but miss the volatile-store-volatile-load case.  This final
- * case is placed after volatile-stores although it could just as well go
- * before volatile-loads.

  • {@code CodeGen:2,CodeInstall:1}
    - * Matches scopes containing "CodeGen" with log level 2, or "CodeInstall" with log level 1. - * - *

  • {@code :1,Dead:0}
    - * Matches all scopes with log level 1, except those containing "Dead". - * - *
  • {@code Code*}
    - * Matches scopes starting with "Code" with log level {@link Debug#DEFAULT_LOG_LEVEL}. - * - *
  • {@code Code,~Dead}

      + * The {@code JMM_*} constants capture the memory barriers necessary to implement the Java Memory + * Model with respect to volatile field accesses. Their values are explained by this comment from + * templateTable_i486.cpp in the HotSpot source code: + * + * 

      + * Volatile variables demand their effects be made known to all CPU's in
+ * order.  Store buffers on most chips allow reads & writes to reorder; the
+ * JMM's ReadAfterWrite.java test fails in -Xint mode without some kind of
+ * memory barrier (i.e., it's not sufficient that the interpreter does not
+ * reorder volatile references, the hardware also must not reorder them).
+ *
+ * According to the new Java Memory Model (JMM):
+ * (1) All volatiles are serialized wrt to each other.
+ * ALSO reads & writes act as acquire & release, so:
+ * (2) A read cannot let unrelated NON-volatile memory refs that happen after
+ * the read float up to before the read.  It's OK for non-volatile memory refs
+ * that happen before the volatile read to float down below it.
+ * (3) Similarly, a volatile write cannot let unrelated NON-volatile memory refs
+ * that happen BEFORE the write float down to after the write.  It's OK for
+ * non-volatile memory refs that happen after the volatile write to float up
+ * before it.
+ *
+ * We only put in barriers around volatile refs (they are expensive), not
+ * _between_ memory refs (which would require us to track the flavor of the
+ * previous memory refs).  Requirements (2) and (3) require some barriers
+ * before volatile stores and after volatile loads.  These nearly cover
+ * requirement (1) but miss the volatile-store-volatile-load case.  This final
+ * case is placed after volatile-stores although it could just as well go
+ * before volatile-loads.
