The goal of these runs is to compare the performance of the latest
versions of LLVM and GCC on x86. Most widely used common
options -O2 and -O3 are taken for all
The used machine is 2.93Ghz Intel Core I7 with 8GB memory
under Fedora Core10.
GCC-4.5.0 is configured with
--enable-checking=release and compiled by GCC-3.4.6.
(it means that GCC-4.5.0 compilation speed can be improved a bit more
if the compiler were bootstrapped or built by more recent version of
GCC). LLVM-2.7 x86 binaries are taken from
LLVM download site.
All changes are given relative to LLVM-2.7.
Here the code size is the corresponding text and data segment size.
