GNUplot charts showing a couple of things:

1. Compile Time
2. Testing Time
3. Time to run some programs, say all of Olden
4. Time to compile something, say Olden.
5. Size of bytecode files for Olden

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:

1. Program - The name of the program for that row.
2. GCCAS - Time to run LLVM optimizers on the program.
3. Bytecode - The size of the bytecode for the program
4. Instrs - The number of LLVM instructions in the compiled bytecode
5. LLC compile - The time taken compile with LLC (the static backend)
6. JIT codegen - The amount of time spent in the JIT itself, instead of executing the program.
7. Machine code - The number of bytes of machine code generated by the JIT.
8. GCC - The time taken to execute the program when compiled with GCC -O2.
9. CBE - The time taken to execute the program after compilation through the C backend, compiled with -O2.
10. LLC - How long does the program generated by the static backend LLC take to execute
11. JIT - The amount of time spent running the program with the JIT; this includes the code generation phase (listed above) and actually running the program.
12. GCC/LLC - The speed-up of the LLC output vs the native GCC output: greater than 1 is a speedup, less than 1 is a slowdown.
