tsan: remove interceptors for termio #24734

llvm/llvm-project#137403
makes tsan build again for glibc after #24640

Do you feel like adding a small standalone test that just builds an executable with TSan enabled?

Rexicon226 · 2025-08-07T19:12:35Z

I was thinking that exact same thought -- but I wonder what targets we should run it for. We used to have MacOS regressions on TSan as well. Should that be included?

alexrp · 2025-08-07T19:24:47Z

In theory:

FreeBSD: aarch64, powerpc64(le), riscv64, x86_64
Linux: aarch64(_be), loongarch64, mips64(el), powerpc64(le), riscv64, s390x, x86_64
macOS: aarch64, x86_64
NetBSD: aarch64(_be), x86_64
Windows: aarch64, x86_64

I have no idea how many of these it'll actually build for in practice though.

Rexicon226 · 2025-08-07T19:38:23Z

Trying it out now.

This is compiling from a x86-64-linux host.
