[llvm-dev] AArch64 always omit leaf frame pointer

[kamlesh kumar via llvm-dev]

Hi Devs,

By default AArch64 omit the frame pointer for leaf function.
But surprisingly, even after passing option -mno-omit-leaf-frame-pointer
behavior remain same.

it is handled at
https://github.com/llvm-mirror/llvm/blob/master/lib/Target/AArch64/AArch64FrameLowering.cpp#L242

Here is a testcase
https://godbolt.org/z/653p3q

Before going for fix,
Like to know community thought on this wether this is a bug or not?
