Then, in a slightly less than ideal world, errors in FPU emulation should be identified and corrected so emulation can be used to run testsuites with confidence.On Mon, 2023-08-28 at 15:17 +0200, Andreas Schwab wrote:On Aug 28 2023, John Paul Adrian Glaubitz wrote:The FP failures are most likely the result of the limitations of the FPU emulation in QEMU for m68k. ARAnyM is known to have much better FPU emulation support than QEMU, so if you want to have more accurate results, you should test on ARAnyM.No, you should test on real hardware. Neither ARAnyM nor QEMU comes close.In an ideal world, I would be testing on real hardware, yes. Unfortunately, even on my Amiga 4000 with 68060/50 MHz the testsuite would run two weeks or so.
After all, we had to change the ABI for TLS support as well, didn't we?Nope.So, any binaries from Debian Potato will still work against glibc 2.38 on m68k?
Haven't gone back to potato, but binaries from sarge still run against glibc from bullseye (that's the latest test image I use - glibc 2.30 IIRC).
Geert kindly provided links to the old filessys-ELF ram disks so I can try and extract binaries from those, but as far as I'm concerned, I'd take Geert's word for it.
Some LD_PRELOAD and LD_LIBRARY_PATH hacking might be necessary to provide libraries missing from a current system, but it can be done. And I occasionally do use binaries that I've compiled on one particular system but cannot readily rebuild on another.
Cheers, Michael
