I'm not sure how to debug this; I don't have access to any IA-64 hardware, and unless I'm missing something QEMU doesn't seem to have an IA-64 emulator. Do you have any idea how other people are debugging IA-64 issues for Debian?

mr-c commented 4 years ago

This is another unofficial architecture for Debian, and on its way out, so I wouldn't worry about it. It is no longer sold either: https://en.wikipedia.org/wiki/IA-64#End_of_life:_2021

FYI Still failing in SIMDe 0.7.0-rc.1

https://buildd.debian.org/status/fetch.php?pkg=simde&arch=ia64&ver=0.7.0%7Erc-1-1&stamp=1606013416&raw=0

Also, some of the new NEON functions also fail in this newer release. Perhaps we should make an official note that IA-64 is not supported?

mr-c commented 3 years ago

The size of the error is getting better, however :-)

Summary of other ia64 issues from the same log mentioned before

arm/neon/ext/vext_f32 arm/neon/max/vmax_f32 arm/neon/pmax/vpmax_f32 arm/neon/st3/vst3_f32 arm/neon/st4/vst4_f32 arm/neon/trn/vtrn_f32 arm/neon/trn1/vtrn1_f32 arm/neon/trn2/vtrn2_f32

(the above on gcc 8, 9, and 10; never did clang 9, 10, nor 11 build successfully for IA-64 on Debian)
