+ <div class="www_sectiontitle">Near-term LLVM Development</div>
+ 
+                 The LLVM infrastructure underlies many ongoing
+                 research projects in our group.  Some key additional
+ 		components of the system that are being developed in these
+ 		projects include:
+               <ul>
+ 		<li><em><strong>Automatic Pool Allocation</strong>:</em>
+ 		A fully automatic program transformation that introduces
+ 	        <i>region-based memory management</i> in a novel manner:
+ 		it partitions the heap into separate regions for distinct
+ 		instances of logical data structures (such as a tree or
+ 		a hash table).
+ 	        </li>
+ 		<li><em><strong>A Software Scheme for Online
+ 		Tracing</strong>:</em> We have developed a tracing scheme that
+ 		identifies frequently executed program paths at runtime,
+ 		and optionally extracts these paths into a software-managed
+ 		trace cache. This currently only works for Sparc code.
+ 		</li>
+ 		<li><em><strong>Transparent runtime optimization on
+ 		general-purpose processors</strong>:</em>
+                 We are developing a transparent trace-based runtime
+ 		optimization system that operates on LLVM traces at runtime,
+ 		using the software tracing mechanism and trace cache above.
+ 		</li>
+                 </ul>
+ 
+ <div class="www_sectiontitle">Longer term research</div>
+ 
+ 		Our group is participating in several ongoing research
+ 		projects, all of which are based on LLVM:
+                 <ul>
+ 		    <li><em><strong><a href="pubs/2003-10-01-LLVA.html">
+ 			Low Level Virtual Architecture (LLVA)</a></strong>:</em>
+ 			A Virtual Instruction Set Computer (VISC) architecture
+ 			decouples the external instruction set (V-ISA) seen by
+ 			all external software from the (possibly
+ 			implementation-specific) hardware ISA used by a
+ 			particular processor implementation (I-ISA).  We
+ 			believe that a variant of LLVM (which we call Low
+ 			Level Virtual Architecture, or LLVA) could be a
+ 			powerful design choice for a V-ISA in such processor
+ 			designs.
+ 			We are exploring the architecture, compiler,
+ 			and operating system benefits of processor designs
+ 			based on LLVA as the virtual ISA.</li>
+ 		    <li><em><strong><a href="safecode/">
+ 		        SAFECode</a></strong>:</em> SAFECode is a
+ 		        compiler-based system for enforcing program
+ 		        safety. SAFECode uses LLVM as its code
+ 		        representation.</li>
+                     <li><em><strong>Macroscopic data structure
+                         analysis and transformations</strong>:</em>
+                         Analyzing and optimizing entire linked
+                         data structures, based on two supporting techniques:
+ 			<em>Data Structure Analysis (DSA)</em> and
+                         <em>Automatic Pool Allocation</em>.
+ 			DSA gives compilers extensive
+ 			static information about the structure, instances,
+ 			and lifetime of entire logical data structures.
+ 			Pool Allocation gives compilers detailed control over
+ 			the layout of such data structures in the heap.
+ 			<em>The DSA pass is included in Release 1.0</em>.
+                         </li>
+                     <li><em><strong>Runtime optimization on
+                         general-purpose processors</strong>:</em>
+                         We are developing techniques for optimizing ordinary
+                         at runtime, by exploiting the LLVM instruction
+ 			set and compiler architecture in ways that would not
+ 			be possible with ordinary static compilation.
+ 			Our tracing and optimization strategy are described
+ 			in the section titled <em><a href="#subprojects">
+ 			Current Development</a></em>.
+ 		      </li>
+                   </ul>

-		Our group is participating in several ongoing research
-		projects, all of which are based on LLVM:
-                <ul>
-		    <li><em><strong><a href="pubs/2003-10-01-LLVA.html">
-			Low Level Virtual Architecture (LLVA)</a></strong>:</em>
-			A Virtual Instruction Set Computer (VISC) architecture
-			decouples the external instruction set (V-ISA) seen by
-			all external software from the (possibly
-			implementation-specific) hardware ISA used by a
-			particular processor implementation (I-ISA).  We
-			believe that a variant of LLVM (which we call Low
-			Level Virtual Architecture, or LLVA) could be a
-			powerful design choice for a V-ISA in such processor
-			designs.
-			We are exploring the architecture, compiler,
-			and operating system benefits of processor designs
-			based on LLVA as the virtual ISA.</li>
-		    <li><em><strong><a href="safecode/">
-		        SAFECode</a></strong>:</em> SAFECode is a
-		        compiler-based system for enforcing program
-		        safety. SAFECode uses LLVM as its code
-		        representation.</li>
-                    <li><em><strong>Macroscopic data structure
-                        analysis and transformations</strong>:</em>
-                        Analyzing and optimizing entire linked
-                        data structures, based on two supporting techniques:
-			<em>Data Structure Analysis (DSA)</em> and
-                        <em>Automatic Pool Allocation</em>.
-			DSA gives compilers extensive
-			static information about the structure, instances,
-			and lifetime of entire logical data structures.
-			Pool Allocation gives compilers detailed control over
-			the layout of such data structures in the heap.
-			<em>The DSA pass is included in Release 1.0</em>.
-                        </li>
-                    <li><em><strong>Runtime optimization on
-                        general-purpose processors</strong>:</em>
-                        We are developing techniques for optimizing ordinary
-                        at runtime, by exploiting the LLVM instruction
-			set and compiler architecture in ways that would not
-			be possible with ordinary static compilation.
-			Our tracing and optimization strategy are described
-			in the section titled <em><a href="#subprojects">
-			Current Development</a></em>.

-		<li><em><strong>Automatic Pool Allocation</strong>:</em>
-		A fully automatic program transformation that introduces

-		it partitions the heap into separate regions for distinct
-		instances of logical data structures (such as a tree or
-		a hash table).
-	        </li>
-		<li><em><strong>A Software Scheme for Online
-		Tracing</strong>:</em> We have developed a tracing scheme that
-		identifies frequently executed program paths at runtime,
-		and optionally extracts these paths into a software-managed
-		trace cache. This currently only works for Sparc code.
-		</li>
-		<li><em><strong>Transparent runtime optimization on
-		general-purpose processors</strong>:</em>
-                We are developing a transparent trace-based runtime
-		optimization system that operates on LLVM traces at runtime,
-		using the software tracing mechanism and trace cache above.
