Subject: [Outliner] Remove no red zone requirment for AArch64
X-Git-Tag: llvmorg-5.0.0-rc1~9217
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=167af85ec7f7fce3d42b5f4bf4bb797d1cba0e0a;p=platform%2Fupstream%2Fllvm.git

[Outliner] Remove no red zone requirment for AArch64

AArch64 doesn't require -mno-red-zone; stack fixups are sufficient here. This was
unnecessarily copied over from the X86 target.

(You can now outline with red zones! Yay!)

Removing the requirement passes all Single/MultiSource tests.
