+// 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 aquire & 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) Similar 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 (that 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

+/**
+ * Uses segment map to find the the start (header) of a nmethod. This works as follows:
+ * The memory of the code cache is divided into 'segments'. The size of a segment is
+ * determined by -XX:CodeCacheSegmentSize=XX. Allocation in the code cache can only
+ * happen at segment boundaries. A pointer in the code cache can be mapped to a segment
+ * by calling segment_for(addr). Each time memory is requested from the code cache,
+ * the segmap is updated accordingly. See the following example, which illustrates the
+ * state of code cache and the segment map: (seg -> segment, nm ->nmethod)
+ *
+ * code cache segmap
+ * ----------- ---------
+ * seg 1 | nm 1 | -> | 0 |
+ * seg 2 | nm 1 | -> | 1 |
+ * ... | nm 1 | -> | .. |
+ * seg m | nm 2 | -> | 0 |
+ * seg m+1 | nm 2 | -> | 1 |
+ * ... | nm 2 | -> | 2 |
+ * ... | nm 2 | -> | .. |
+ * ... | nm 2 | -> | 0xFE |
+ * seg m+n | nm 2 | -> | 1 |
+ * ... | nm 2 | -> | |
+ *
+ * A value of '0' in the segmap indicates that this segment contains the beginning of
+ * an nmethod. Let's walk through a simple example: If we want to find the start of
+ * an nmethod that falls into seg 2, we read the value of the segmap[2]. The value
+ * is an offset that points to the segment that contains the start of the nmethod.
+ * Another example: If we want to get the start of nm 2, and we happen to get a pointer
+ * that points to seg m+n, we first read seg[n+m], which returns '1'. So we have to
+ * do one more read of the segmap[m+n-1] to finally get the segment header.
