Zig Version

eadc0c0

Steps to Reproduce and Observed Behavior

zig test -target aarch64_be-linux-none test/behavior/math.zig --test-cmd qemu-aarch64_be --test-cmd-bin

Upstream bug: llvm/llvm-project#103032

This is just meant as a tracking issue on our side. I consider this bug a blocker for any meaningful aarch64_be progress with LLVM; I eventually gave up trying to disable affected behavior tests and std tests.

Expected Behavior

No LLVM crash.

Upstream bug has been fixed; I'll resume work on aarch64_be support once we upgrade to LLVM 19.

i think tracking issues such as this usually stay open until the llvm 19 upgrade is completed
