"wasm32-wasi 3.x" buildbot times out on building Python #151929
Description
Bug report
The wasm32-wasi 3.x buildbot worker seems to be affected by this LLVM (clang) performance issue: llvm/llvm-project#179695. Sometimes, the "Compile build Python" step is killed by a timeout.
Example of failure: the "Compile build Python" times out after 35 minutes 10 seconds.
clang -shared Modules/pyexpat.o -lm Modules/expat/libexpat.a -o Modules/pyexpat.cpython-316d-x86_64-linux-gnu.so
clang -shared Modules/_elementtree.o -o Modules/_elementtree.cpython-316d-x86_64-linux-gnu.so
command timed out: 1200 seconds without output running [b'python3', b'Tools/wasm/wasi.py', b'make-build-python'], attempting to kill
process killed by signal 9
program finished with exit code -1
"Compile build Python" uses clang -Og.
