+##########################################################################################
+#
+# This Makefile, together with Tools.gmk, can be used to compile a set of
+# gcc based cross compilation, portable, self contained packages, capable
+# of building OpenJDK.
+#
+# In addition to the makefiles, access to Oracle Linux installation
+# media is required. This has been tested against Oracle Enterprise Linux
+# 5.5. Set variables RPM_DIR_x86_64 and RPM_DIR_i686 respectively to point
+# to directory containing the RPMs.
+#
+# By default this Makefile will build crosstools for:
+# * i686-unknown-linux-gnu
+# * x86_64-unknown-linux-gnu
+# The x86_64 version of the compilers will work in multi arch mode and will
+# be able to compile 32bit binaries with the -m32 flag. This makes the
+# explicit cross compiler for i686 somewhat redundant and is a known issue.
+#
+# To build the full set of crosstools, use a command line looking like this:
+#
+# make tars RPM_DIR_x86_64=/tmp/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
+#
+# To create a x86_64 package without the redundant i686 cross compiler, do
+# like this:
+#
+# make tars platforms=x86_64-unknown-linux-gnu RPM_DIR_x86_64=/tmp/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/

+Events in the JVM are by default timed (it's more common)
+Perhaps a little strange. Might change.
+
+EVENTS
+
+Declard with the 'event' tag.
+
+<value fields> can be one or more of
+ value - a simple primitive or constant type value
+ structvalue - value is a sub-struct. This type must be previously defined
+ with 'struct'
+All these require you to declare type, field and label of the field. They also accept
+an optional description of the field. If the meaning of the field is not obvious
+from the label you should provide a description. If an event however is not actually
+meant for end-users, you should probably _not_ write descriptions at all, since you
+might just add more concepts the user has no notion of/interest in.
+
+Events should be modeled after what conceptual process you are expressing, _NOT_
+from whatever data structures you might use inside the JVM for expressing a process.
+
+
+STRUCT
+
+Declared with the 'struct' tag.
+
+Declares a structure type that can be used in other events.

+
+Content types (complex) should create constant pool data
+in the recording.
+Currently at least, there is _NO_ verification that whatever
+writer you have is actually writing correctly. So BE CAREFUL!
+
+Declared with the 'content_type' tag.
+
+<type> is the ID type, i.e the integer type that resolves this. Most often
+U4 or U8, but for example really small number constants, like GCTYPE uses U1.
+
+<content-type> is where it gets interesting. 'builtin_type' means we're
+defining how we resolve one of the trace built-in types (Class, Thread etc),
+jvm_type means defining a new one for our own use.
+
+Example: (GcMode)
+
+<content_type id="GCMode" hr_name="GC mode" type="U1" jvm_type="GCMODE">
+ <value type="UTF8" field="desc" description="Description"/>
+</content_type>
+
+This creates a content type CONTENT_TYPE_GCMODE
+The field type referencing it is u1 (U1), and the constant pool struct has one field, the name.
+
+Before we can use it we need also define a primary field data type:
+
+<primary_type symbol="GCMODE" datatype="U1" contenttype="NONE"
+ type="u8" sizeop="sizeof(u1)"/>
+
+Now we can use the content + data type in declaring event fields.
+Remember however, that for us to be able to resolve the value later we must also add
+creating the constant pool data in VM_JFRCheckpoint::write_checkpoint
+
+ ...
+ //CGMODE
+ w->be_uint(CONTENT_TYPE_GCMODE);
+ w->be_uint(MM_GC_MODE_UNINITIALIZED);
+ for (i = 0; i < MM_GC_MODE_UNINITIALIZED; i++) {
+ w->uchar(i);
+ w->write_utf8(gcModeGetName(i));
+ }
