[Iverilog-devel] Icarus Verilog vvp32 on 64bit systems

[Stephen W. <st...@ic...>]

Question:

Does *anybody* use or even see value in the 32bit runtime support
that Icarus Verilog includes in 64bit builds? In particular, there
is support in the Icarus Verilog source for building simultaneously
a vvp (64bit) and a vvp32 (32bit) to support 32bit VPI's transported
from 32bit systems.

I personally have never used the vvp32 and I'm starting to run
into cases where it is actively getting in the way. I'm considering
removing the whole business and forgetting about it, although there
may be alternatives.

When I first implemented it, I was not particularly clear on how
the 64/32 compatibility worked on Linux. If there is interest in
keeping up 32bit runtime support (i.e. vvp32 on 64bit systems) then
it may be better handled by a more compliant method. Perhaps it
can be tied in with multi-version support, which is missing so far.

Ideas?
