AArch64CollectLOH: Rewrite as block-local analysis. Re-apply r288561: This time with a fix where the ADDs that are part of a 3 instruction LOH would not invalidate the "LastAdrp" state. This fixes http://llvm.org/PR31361 Previously this pass was using up to 5% compile time in some cases which is a bit much for what it is doing. The pass featured a full blown data-flow analysis which in the default configuration was restricted to a single block. This rewrites the pass under the assumption that we only ever work on a single block. This is done in a single pass maintaining a state machine per general purpose register to catch LOH patterns. Differential Revision: https://reviews.llvm.org/D27329 This reverts commit 9e6cedb0a4f14364d6511597a9160305e7d34493. llvm-svn: 291266 2017-01-06 20:22:01 +01:00			`; RUN: llc -o - %s -mtriple=arm64-apple-ios -O2 \| FileCheck %s`
ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090 2014-03-29 11:18:08 +01:00			`; Test case for <rdar://problem/15942912>.`

[opaque pointer type] Add textual IR support for explicit type parameter to gep operator Similar to gep (r230786) and load (r230794) changes. Similar migration script can be used to update test cases, which successfully migrated all of LLVM and Polly, but about 4 test cases needed manually changes in Clang.
