For Ferrocene I needed to run the test suite for custom target with no unwinding and static relocation. Running the tests uncovered ~20 failures due to the test suite not accounting for these options. This PR fixes them by:
CHECK
s to account for functions having extra LLVM IR attributes (in this casenounwind
).CHECK
s to account for thedso_local
LLVM IR modifier, which is added to every item when relocation is static.CHECK
s to account for missinguwtables
attributes.needs-unwind
attributes for tests that are designed to check unwinding.There is no part of Rust CI that checks this unfortunately, and testing whether the PR works locally is kinda hard because you need a target with std enabled but no unwinding and static relocations. Still, this works in my local testing, and if future PRs accidentally break this Ferrocene will take care of sending followup PRs.
