Description
Possible WebKit issue with SSE/SSE2 op-codes. Attached is the debug log file. I've tried several of the recent nightly builds and they all have this problem.
Shouldn't the architecture for WebKit/Webpositive work for all pentium class PCs? http://sprunge.us/aDIV

Could you try the latest nightly? I modified the build files to target the i686 CPU, but I don't know if this will be enough, as WebKit also uses generated assembler code for the javascript interpreter.

OK, I'll try it and get back to you. If it starts, I assume you'd like me to try a website with javascript ... right? Do you have any specific site you want me to test?

Got feedback on IRC, adding it here before I forget: Even after adding the -march=i686 flag to WebKit, this doesn't work. My guess is the JavaScript engine is going to use SSE opcodes anyway. I'm afraid we can't do much more.

It is strange how all the other applications work fine, like wonderbrush, beam, vision, OpenGL demo, etc.
As I understand it, the Pentium III has the P6 core and SSE, just not SSE2.
I'm attaching the debug logs for build version 46670 and 46656.

It seems GCC uses SSE2 instructions for floating point operations. Either target the pentium/pentium3 archs or use "-mno-sse2".

We're already compiling with -march=i686, but I'll try adding -mno-sse2...

Fixed in https://github.com/haiku/webkit/commit/9619b6badfee396439e44291e41411845e72743e. One of the build scripts was enabling sse2 behid our back.
