I read DBorca was hired away (was it VMWare?). If I recall this correctly, it sounds like siphoned the talent from these amazing libraries. There must have been few people who worked on it and explored its potential.

I'll search for the comment. Also, the hand written assembly optimizations have small effect (I think this has been documented, too), so the compiler optimizations are not expected to do any good, as you have measured. Like discussed earlier, if even the C path works equivalently, then that's just …

I agree entirely. There is no need to use flags that are problematic and the code is already optimal as you said. I hope the library versions do not require much more work.

You have very interesting findings. On glide3 makefiles I've seen prior, they have this: ifeq ($(USE_X86),1) CFLAGS += -DGL_X86 OPTFLAGS ?= -O1 -ffast-math -mcpu=pentium else CFLAGS += -DGLIDE_USE_C_TRISETUP OPTFLAGS ?= -O1 -ffast-math endif I recall that this is documented (maybe a code comment?) …

Great, that's welcome news. Edit: I'll return in a bit.

Ok, I'll monitor the branch over the next few minutes.

I wonder if this line is compatible with newer gcc versions: ASFLAGS = -O6.

Excellent! Please see if this one is better. It has the mmx running for sure, or as sure as the stdout shows.

This binary shows the mmx, too, so this one would meet your request fully as think possible for the cvg (instead of the immediately prior one).

I'll remove the mcpu=p1 and see what happens.

I don't think the binary built with all the optimizations yet, even though I ran the command line correctly. However, I'll continue to test the compiles until it shows all optimizations in stdout/stderr while building.
