Since MS-DOS has it’s 6.1.0 I was dying to re-build stuff for 6.1.0. As I don’t want to build it myself I did mange to find a version on equation.com
I rebuilt Cockatrice III, and that seems to be running fine.
Continuing from my GCC 1.40 on Windows, here is version 6.1.0’s scores:
Dhrystone(1.1) time for 500000000 passes = 53
This machine benchmarks at 9433962 dhrystones/second
Dhrystone(1.1) time for 500000000 passes = 18
This machine benchmarks at 27777777 dhrystones/second
Dhrystone(1.1) time for 500000000 passes = 16
This machine benchmarks at 31250000 dhrystones/second
Dhrystone(1.1) time for 500000000 passes = 13
This machine benchmarks at 38461538 dhrystones/second
As you can see the scores are actually slower than GCC 5.1.0. Well that was kind of surprising. Since I almost never read the manual, I did find out about -Ofast vs -O3/-O2, and yes, it is much faster! So I guess I should recompile everything with GCC 5.1.0 … But I do prefer the diagnostic messages in GCC 6, it’s very CLANG like.
