Evan Cheng	25f7df1bce	Use pushq / popq instead of subq $8, %rsp / addq $8, %rsp to adjust stack in prologue and epilogue if the adjustment is 8. Similarly, use pushl / popl if the adjustment is 4 in 32-bit mode. In the epilogue, takes care to pop to a caller-saved register that's not live at the exit (either return or tailcall instruction). rdar://8771137 llvm-svn: 122783	2011-01-03 22:53:22 +00:00
Evan Cheng	7d8c39bb1c	Do not force indirect tailcall through fixed registers: eax, r11. Add support to allow loads to be folded to tail call instructions. llvm-svn: 98465	2010-03-14 03:48:46 +00:00
Jeffrey Yasskin	53a8f3981c	Fix http://llvm.org/PR5729 : x86-64 tail calls were putting their targets into R11, and then asserting that the target was in R9. Since R9 isn't reserved for the target anymore, and is used as an argument, this patch changes the assertion. llvm-svn: 93065	2010-01-09 18:56:43 +00:00

prologue and epilogue if the adjustment is 8. Similarly, use pushl / popl if
the adjustment is 4 in 32-bit mode.

In the epilogue, takes care to pop to a caller-saved register that's not live
at the exit (either return or tailcall instruction).
