Hi
I've updated the benchmarks, added comparsion script and some
new tests.
It can be found at
ftp://ftp.ta.jcu.cz/pub/linux/hubicka/experimental/egcs-benchmark2.tgz
Results of latest snapshot are following:
Comparsions are printed in following order:
my_patch previous_snapshot egcs1.0 egcs2.7.2
(there is quite large (60%) improvement in B7 test and small slowdown
(5%) in bzip2 and XaoS internal loop. Other tests are almost unchanged.
Compiler crashes at slalom benchmark. Compared to egcs1.0 there is important
slowdown in quick sort test. It seems to be created by higher register
pressure caused by not using the addresing modes to get array elements.
Other significant slowdown is in Mandelbrot loop using complex numbers.
It seems to be inconvience caused by reg-stack pass after scheduling.
It generates too many xchg instructions.)
