Reid Kleckner a0bb44f171 musttail: Forward regparms of variadic functions on x86_64 ... Summary: If a variadic function body contains a musttail call, then we copy all of the remaining register parameters into virtual registers in the function prologue. We track the virtual registers through the function body, and add them as additional registers to pass to the call. Because this is all done in virtual registers, the register allocator usually gives us good code. If the function does a call, however, it will have to spill and reload all argument registers (ew). Forwarding regparms on x86_32 is not implemented because most compilers don't support varargs in 32-bit with regparms.
