Evan Cheng	7158e08b8e	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122783 91177308-0d34-0410-b5e6-96231b3b80d8	2011-01-03 22:53:22 +00:00
Evan Cheng	f48ef03655	Do not force indirect tailcall through fixed registers: eax, r11. Add support to allow loads to be folded to tail call instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98465 91177308-0d34-0410-b5e6-96231b3b80d8	2010-03-14 03:48:46 +00:00
Jeffrey Yasskin	a77169dbeb	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93065 91177308-0d34-0410-b5e6-96231b3b80d8	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.
