I decided to try to generate snapshot for those systems.
It finally worked (with OPT=-O- option added)
You can test them at:
ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/mipsel-linux/
or
ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/mips-linux/
Please give feedback,
I'm just about moving again here, but with a decided limp: the system
that blew was 2.8GHz and all my guest OSes are now plugged into a 1GHz
box. I still find being able to use a significant number of different
guests in sleds/caddies useful... Unfortunately I've still not got any
real MIPS hardware running here, so I'm still stuck on Qemu.
The good news is that I can still run/build trunk for mipsel on Debian
"Squeeze" on Qemu without unanticipated issues (i.e. nobody reading this
should assume that Lazarus will work yet).
The not-so-good news is that I built from trunk earlier but after having
bus errors in Qemu's implementation of big-endian MIPS I'm now looking
at the file above. Unfortunately I still get bus errors and I think the
binaries have been stripped.
This is very strange:
I just installed the snapshot onto the big-endian mips machine
that I use to generate the snapshot.
This machine is the one that does generate daily testsuite results for
mips-linux.
I just tested a compiler cycle (with DEBUG=1) starting from this
snapshot binary, and it seems to be able to generate a vanilla trunk
ppcmips:
ppcmips -iDW
2012/11/21 2.7.1-r1:23032
Is this a Qemu problem?
But I see no other problems, except those that could be caused by
slowness of the emulated environment (flush process timing out, which
appears to be a known issue). I suggest you compile a null program and
"Hello, World!" and upload them.
This is one of the reasons that I'm trying to get at least one genuine
SGI system running, I don't entirely trust Qemu as a reference platform.
However booting Linux on the Origin 200 looks "challenging", one Octane
has a blown PSU and the other trips the RCD (suspect filter).
