The latency of the mtlr can now be hidden by the loads of thecallee saved registers.This commit is almost identical to this one: r322036 except that two warningsthat broke build bots have been fixed.The revision number is D41737 as before.llvm-svn: 322124 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/PowerPC/ppc-redzone-alignment-bug.ll Tue, 09 Jan 2018 21:57:49 +0000 Stefan Pintilie <stefanp@ca.ibm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/PowerPC/ppc-redzone-alignment-bug.ll#7e10987b Revert "[PowerPC] Manually schedule the prologue and epilogue"[PowerPC] This reverts commit r322036.Failing build bots.

The available program storage region of the red zone to compilers is 288 bytes rather than 244 bytes.2. The formula for negative number alignment calculation should bey = x & ~(n-1) rather than y = (x + (n-1)) & ~(n-1).Differential Revision: https://reviews.llvm.org/D34337llvm-svn: 307672 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/PowerPC/ppc-redzone-alignment-bug.ll Tue, 11 Jul 2017 16:42:20 +0000 Tony Jiang <jtony@ca.ibm.com>
