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
Eric Christopher	0100a8fda4	Remove extraneous copy from DAG conversion for darwin tls. This was ... popping up at O0 when it wasn't folded and the fast allocator would complain. llvm-svn: 121330	2010-12-09 00:27:58 +00:00
