[PATCH] D39386: [Power9] Allow gpr callee saved spills in prologue to vector registers rather than stack

[Zixuan Wu via Phabricator via llvm-commits]

wuzish added inline comments.
Herald added a project: LLVM.


================
Comment at: llvm/trunk/lib/Target/PowerPC/PPCFrameLowering.cpp:1975
+// vector register. This occurs for leaf functions when the option
+// ppc-enable-pe-vector-spills is enabled. If there are any remaining registers
+// which were not spilled to vectors, return false so the target independent
----------------
I am wondering why it's not enabled by default? @syzaara
