ENABLE_JIT is on by default in all architectures, but if I'm not wrong it's only supported in x86, x86_64, armhf and arm64. The build fails everywhere else, so I have to pass -DENABLE_JIT=OFF explicitly. It would be nice it ENABLE_JIT would be already off by default when it's not supported.
by the way X86 is not supported, only X86_SSE2
I think this can be closed because it is already fixed (more or less) here: https://bugs.webkit.org/show_bug.cgi?id=186722 I created an other bug for non-SSE2 X86: https://bugs.webkit.org/show_bug.cgi?id=188476
Yup *** This bug has been marked as a duplicate of bug 186722 ***
