[webkit-gtk] webkitgtk-1.10 crashes on some AMD processors

[Daniel Drake]

Hi,

webkitgtk-1.10 enables the new LLint/offlineasm javascript optimizations.
These require a SSE2-compatible processor on x86.

This means that webkitgtk-1.10 doesn't work on various classes of AMD
processors including the Geode (used in OLPC XO-1), Athlon XP, ... and
also some VIA processors, probably others. Loading Google results in a
SIGINT crash when a SSE2 instruction is executed.

It looks like the only option (beyond explicitly dropping support for
these processors) is disabling LLint on x86 32-bit. Is that something
that can be done in webkitgtk?
