2023597 - LLVM >22.1 compilation fails as clock() is no longer found due to deprecation: wasm32-wasi target has been renamed to wasm32-wasip1

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Matthijs Vrolijk]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:148.0) Gecko/20100101 Firefox/148.0

Steps to reproduce:

Compile on Arch (with -testing repositories enabled) using Clang 22.1.1

Actual results:

Compilation fails at configuration stage: deprecation of wasm32-wasi breaks tmp code finding clock()

Expected results:

Normal compilation. Changing line 939 of build/moz.configure/toolchain.configure
"return split_triplet("wasm32-wasi", allow_wasi=True)" to "return split_triplet("wasm32-wasip1", allow_wasi=True)" resolves this issue.
