[Help wanted]: SWIPL wasm build not compatible with emsdk v4

General
1

Our CI in swipl-wasm is broken when trying to auto update to emsdk v4 [1]. Unfortunately, I do not have time to resolve this issue myself at present; so any support in resolving this issue will be greatly appreciated.

Note the fix will need to be upstream in the swipl-devel repo [2].

The issue has been fixed in the GIT version. But … running the benchmarks using node shows a slowdown of approximately 3 times :frowning: Does anyone know why Emscripten 4 is so much slower than 3?

Oops. The Emscripted -sASSERTIONS was still in effect. Emscripten 4 performance is the same as the latest Emscripten 3 release. Sorry for the noise.
