So that on entry to a procedure that calls other procedures, you can
subtract STACK_PADDING from esp to get a 16-byte aligned stack
pointer.
On Windows x86-64, you have to reserve space i

This problem is related to the problem I mentioned earlier in regard to
upgrading list.factor. I am now upgrading symtab.factor
(www.rosycrew.org/symtab.factor) and it won't compile. All of the functions

Hi Slava,
I tried using STRUCT: instead of C-STRUCT: in vm.factor, but this
generates a bootstrap error on loading the vocab. The problem seems to
occur when using the 'zone' struct in the 'vm' struct. If I replace '{

Hi Slava,
Why is STACK_PADDING=56 in cpu-x86.64.S?
I originally assumed this was because the return address got pushed
during the call instruction (which would then align rsp to 16bytes), but
if that's the case what happens to the calls in cpu-x86.S that don't
have this padding?
Thanks,
Phil
Hi,
Factor's strings are now multiline and a new syntax -- """Triple

inside the string, and i

Is it in the Windows binary version yet? (I'm assuming not, as that is
from the 21st). Once there's a binary with it in I'll test (SSE2) but
I can't build my own at the moment, sorry.

Another change is that binary packages on x86-32 no longer require SSE3.

Yep, these forwarding functions should probably just be a 1 line macro:
