More than 60% of the tests are failing on the three Debian big-endian architectures s390x, ppc64, sparc64:
https://buildd.debian.org/status/fetch.php?pkg=spirv-llvm-translator-17&arch=s390x&ver=17.0.0-4&stamp=1707586764&raw=0
https://buildd.debian.org/status/fetch.php?pkg=spirv-llvm-translator-17&arch=ppc64&ver=17.0.0-4&stamp=1707587023&raw=0
https://buildd.debian.org/status/fetch.php?pkg=spirv-llvm-translator-17&arch=sparc64&ver=17.0.0-4&stamp=1707595393&raw=0
(Testsuite failures are currently fatal only on amd64: issue #1964)
Furthermore, running the testsuite on big-endian architectures requires >40GB of diskspace (while it only needs around 500MB on little-endian architectures). One particularily huge (40GB) file is build/test/test_output/DebugInfo/Generic/Output/two-cus-from-same-file.ll.tmp
Similar results happen on the other branches.

In comparison, on the little-endian architecture ppc64el only 8 tests are failing:
