Global merge for global symbols. This commit is to improve global merge pass and support global symbol merge. The global symbol merge is not enabled by default. For aarch64, we need some more back-end fix to make it really benifit ADRP CSE. llvm-svn: 210640

[CodeGen] Split -enable-global-merge into ARM and AArch64 options. Currently, there's a single flag, checked by the pass itself. It can't force-enable the pass (and is on by default), because it might not even have been created, as that's the targets decision. Instead, have separate explicit flags, so that the decision is consistently made in the target. Keep the flag as a last-resort "force-disable GlobalMerge" for now, for backwards compatibility. llvm-svn: 234666

[AArch64, ARM] Enable GlobalMerge with -O3 rather than -O1. The pass used to be enabled by default with CodeGenOpt::Less (-O1). This is too aggressive, considering the pass indiscriminately merges all globals together. Currently, performance doesn't always improve, and, on code that uses few globals (e.g., the odd file- or function- static), more often than not is degraded by the optimization. Lengthy discussion can be found on llvmdev (AArch64-focused; ARM has similar problems): http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-February/082800.html Also, it makes tooling and debuggers less useful when dealing with globals and data sections. GlobalMerge needs to better identify those cases that benefit, and this will be done separately. In the meantime, move the pass to run with -O3 rather than -O1, on both ARM and AArch64. llvm-svn: 233024

IR: Make metadata typeless in assembly Now that `Metadata` is typeless, reflect that in the assembly. These are the matching assembly changes for the metadata/value split in r223802. - Only use the `metadata` type when referencing metadata from a call intrinsic -- i.e., only when it's used as a `Value`. - Stop pretending that `ValueAsMetadata` is wrapped in an `MDNode` when referencing it from call intrinsics. So, assembly like this: define @foo(i32 %v) { call void @llvm.foo(metadata !{i32 %v}, metadata !0) call void @llvm.foo(metadata !{i32 7}, metadata !0) call void @llvm.foo(metadata !1, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{metadata !3}, metadata !0) ret void, !bar !2 } !0 = metadata !{metadata !2} !1 = metadata !{i32* @global} !2 = metadata !{metadata !3} !3 = metadata !{} turns into this: define @foo(i32 %v) { call void @llvm.foo(metadata i32 %v, metadata !0) call void @llvm.foo(metadata i32 7, metadata !0) call void @llvm.foo(metadata i32* @global, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{!3}, metadata !0) ret void, !bar !2 } !0 = !{!2} !1 = !{i32* @global} !2 = !{!3} !3 = !{} I wrote an upgrade script that handled almost all of the tests in llvm and many of the tests in cfe (even handling many `CHECK` lines). I've attached it (or will attach it in a moment if you're speedy) to PR21532 to help everyone update their out-of-tree testcases. This is part of PR21532. llvm-svn: 224257
