Subject: [AArch64] Register (existing) AArch64BranchRelaxation pass with LLVM pass manager.
X-Git-Tag: studio-1.4~832
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1c81432eb6f1a6bcca1f1763aea7748a06acb6b2;p=platform%2Fupstream%2Fllvm.git

[AArch64] Register (existing) AArch64BranchRelaxation pass with LLVM pass manager.

Summary: Among other things, this allows -print-after-all/-print-before-all to
dump IR around this pass.
