I think doing this in GCC is going to be tricky as normal calls only save the the least significant 32-bits. Maybe we could somehow confine 64-bit register values to the call clobbered registers. Normally register pairs are used for 64-bit values. In 64-bit mode, we can probably easily benefit from using the new 64-bit millicode. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=7625
