# RETRO 2019.10
|
|
|
|
This is a worthwhile release, bringing changes and improvements
|
|
in several areas.
|
|
|
|
## 64-Bit
|
|
|
|
RETRO has been 32-bit only since the days of RETRO2 apart from
|
|
some limited experiments with RETRO11. I'm pleased to say that
|
|
this release of RETRO12 adds support for building a system with
|
|
64-bit cells.
|
|
|
|
This carries the same limitations regarding instruction packing,
|
|
addressing, etc as the standard 32-bit system, and is not built
|
|
by default. If you want to build a 64-bit system, do:
|
|
|
|
make clean; make CFLAGS="-O2 -DBIT64"
|
|
|
|
## Compatibility
|
|
|
|
There are a few small breaks in compatibility.
|
|
|
|
`unix:time` was removed. There is some discussion ongoing about
|
|
this, but leaving it in would be problematic on 32-bit systems
|
|
in a couple of years when the counter overflows. For now, I have
|
|
added `clock:timestamp`, but the value of the epoch this uses
|
|
may change in the future.
|
|
|
|
The time functions in the `clock:` namespace are now part of
|
|
their own I/O device. This aids in allowing them to be enabled
|
|
on a VM that disables the Unix system interface. In this release
|
|
the time functions remain accessible via the Unix device, but
|
|
this will be dropped in the next release.
|
|
|
|
## User Interface
|
|
|
|
The 'ok' prompt has been removed.
