Recover or re-create ppc-testresults.dat.bz2

[ianfixes]

From doc/PowerPC-Testsuite.md:

It is recommended that you first run the tester on a native PowerPC platform to generate a results file. For reference, here is the [[this>projects/ppctester/files/ppc-testresults.dat.bz2|PowerPC Emulator Tester results file]] I use for SheepShaver. This was generated with AltiVec tests enabled. This is for revision 1.30+ of the file. md5sum is: ''3e29432abb6e21e625a2eef8cf2f0840''.

We should do that, and save the file here for posterity.

(Note: this issue was originally emaculation/SheepShaver#10)

What even is this testsuite? Is it actually in the codebase somewhere?

[rakslice]

Oh, I get it, it's test-powerpc.cpp.

It basically has two modes; if you run it on a native PowerPC system, it tests the local CPU and writes the results to a file. Otherwise, it takes a results file, does a test on the emulated CPU (using the JIT if you pass --jit first) and compares the results with the results file.

It has no concept of anything but real (one-to-one with the host system) memory addresses.

Correct, this issue is to track getting/generating a copy of that results file so that we could actually test against it in this repo.

There's an apparent archived copy at http://web.archive.org/web/20060217123013/http://www.gibix.net/projects/ppctester/files/ppc-testresults.dat.bz2

This was a good lead, but upon downloading every version they had I didn't get the right MD5

$ md5 ppc-testresults*
MD5 (ppc-testresults (1).dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3
MD5 (ppc-testresults (2).dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3
MD5 (ppc-testresults (3).dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3
MD5 (ppc-testresults (4).dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3
MD5 (ppc-testresults (5).dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3
MD5 (ppc-testresults.dat.bz2) = 60172863f951c72e1ee7e01d54ed6db3

I wonder if @cebix or @FreeBSD-pzn can comment on its suitability of this other version of the test file

[rakslice]

Try md5summing the file in the archive :D

🎉 👍 🥇 !!!

This is excellent, I hadn't imagined that this file would ever turn up.

I've opened #139 to track making actual use of this file as part of CI
