Here are some charts showing how the LLVM optimizer and code generators are
changing over time.  For now we use the Olden benchmark suite to measure this,
but eventually we will switch to using SPEC CPU2000.  All programs are run with
"LARGE_PROBLEM_SIZE" enabled.  Click on any of the charts to get a larger
version.<p>

This section tests LLVM on a variety of programs in the test suite.  This
includes benchmark suites like the Olden, McCat, Ptrdist, and SPEC benchmarks as
well as a few random programs with test inputs.  This section is meant to track
how stable LLVM is as a whole. A failure in the execution of any test is marked
with an asterisk: `*'. The columns of the tables are:<p>

<ol>
<li><a name="Program">Program</a> - The name of the program for that row.</li>
<li><a name="GCCAS">GCCAS</a> - Time to run LLVM optimizers on the program.</li>
<li><a name="Bytecode">Bytecode</a> - The size of the bytecode for the
    program</li>
<li><a name="Instrs">Instrs</a> - The number of LLVM instructions in the
    compiled bytecode</li>
<li><a name="LLC<br>compile">LLC compile</a> - The time taken compile with
    LLC (the static backend)</li>
<li><a name="JIT<br>codegen">JIT codegen</a> - The amount of time spent in the
    JIT itself, instead of executing the program.</li>
<li><a name="Machine<br>code">Machine code</a> - The number of bytes of machine
    code generated by the JIT.</li>
<li><a name="GCC">GCC</a> - The time taken to execute the program when compiled
    with GCC -O2.</li>
<li><a name="CBE">CBE</a> - The time taken to execute the program after
    compilation through the C backend, compiled with -O2.</li>
<li><a name="LLC">LLC</a> - How long does the program generated by the static
    backend LLC take to execute </li>
<li><a name="JIT">JIT</a> - The amount of time spent running the
    program with the JIT; this includes the code generation phase (listed above)
    and actually running the program.</li>
<li><a name="GCC/LLC">GCC/LLC</a> - The speed-up of the LLC output vs the native 
    GCC output: greater than 1 is a speedup, less than 1 is a slowdown.</li>
<li><a name="GCC/CBE">GCC/CBE</a> - The speed-up of the CBE output vs the native 
    GCC output: greater than 1 is a speedup, less than 1 is a slowdown.</li>
<li><a name="LLC-BETA">LLC-BETA</a> - How long does the program generated by the static
    backend LLC take to execute the program, when compiled with new experimental 
    features.  This is temporary, for tuning.</li>
