Hi Tom,

This is something I'd like to get an answer to, too. I did see in a comment in one of the older changes 1 that:

•   // Spill because stubs can use any register they like and it's

•   // easier to restore just those that we care about.

Which doesn't really sound reassuring...

Can someone point me to the x86-64 calling convention for stubs created by stubGenerator? In particular, which xmm registers if any must be preserved and which are volatile. -- Tom Deneau -------------- next part -------------- An HTML attachment was scrubbed...
