Actually if you generate a new VM using the latest VMMaker, ask Tim, you will find it will generate a backwards compatible entry point so that older versions of the FFI plugin will still work

However I'm not sure you've generated a new vm and ffi plugin because of the warning messages you have received below

#warning * interp.h not found -- defaulting to a 32-bit VM The unix vm config process builds this file.

#warning * update your image-side VM sources to the latest #warning * version to avoid this message

This is with the current SVN sources and a freshly generated interpreter from a clean, fully updated, 3.8 image.

I have not been able to build a VM in 6 months or so... What happened to the good old days when the VM would always build and the only errors were a result of my own ill-advised hacks?

FFI needs to work in order to support Croquet... =\

Last time I complained about the lack of VM API documentation someone mentioned an obscure out-of print book that documents an obsolete version of the interface...

It's neither out of print nor obsolete:

And the lesson is: Stick with the compiler that produces the best code, not the highest version number. I'm still using 2.95.2 on Windows and as long as there isn't a GCC version which is at least at par with 2.95 on x86 (all other versions I've tried where substantially slower) I won't switch ;-)

Cheers, - Andreas

Comment:

Gcc 3.1.0 had problems with its optimizer such that it inserted worthless register loads into the instruction stream -- maybe that bug is back.....

With gcc 3.1, the performance saw a substantial improvment when it was compiled with -O0 -- that was not the case this time...

With -O1, however, there was a substantial improvment, though still much worse than my workhorse VM...
