Nice, I'm just finishing download of icc8.0, anyway, como433 x gcc340
testing is finished, just to show few interesting numbers here (the full
table comparison will be sent with icc8.0 results too):
[1] [2] [3]
pi.cc 17.53 5.58 -214.16
pi_impl.cc 24.79 8.91 -178.23
typecode_seq.cc 14.99 4.97 -201.61
timebase.cc 14.44 4.94 -192.31
ir.cc 53.89 12.62 -327.02
ir_base.cc 17.64 5.52 -219.57
imr.cc 23.93 6.4 -273.91
[1]: GCC 3.4.0 as in previous tests -O0 optimize option
[2]: COMO 4.3.3 + GCC 3.3.2 backend, -O0 optimize option (note that GCC
is used as an ``assembler'' here, so the time to compile produced C
code is not counted (i.e. como is ``just'' C++ to C compiler)
[3]: delta in %
As I said, stay tuned to see more results! :-)
