Description Mike Hommey [:glandium] 2011-10-21 08:54:25 PDT
I'm getting SIGILL on S390 when running xpcshell during packaging, when generating startup cache. What seems to happen is that some compiler optimizations are breaking the NS_InvokeByIndex assembly. Compiling xptcinvoke_linux_s390.cpp without optimization makes xptcinvoke work.

However, the function call convention on s390 is pretty straightforward, and can actually be implemented in pure C like we have on e.g. x86-64 or ARM.

rubberstamping port-specific code, I'm not really interested in reviewing it anyway.
