Reapply DW_AT_low/high_pc patch: Use the range machinery for DW_AT_ranges and DW_AT_high/lo_pc. This commit moves us from a single range per subprogram to extending ranges if we are: a) In the same section, and b) In the same enclosing CU. This means we have more fine grained ranges for compile units, and fewer ranges overall when we have multiple functions in the same CU adjacent to each other in the object file. Also remove all of the earlier hacks around this functionality for function sections etc. Also update all of the testcases to take into account the merging functionality. with a fix for location entries in the debug_loc section: Make sure that debug loc entries are relative to the low_pc of the compile unit. This means that when we only have a single range that the offset should be just relative to the low_pc of the unit, for multiple ranges for a CU this means that we'll be relative to 0 which we emit along with DW_AT_ranges. This mostly shows up with linked binaries, so add a testcase with multiple CUs so that our location is going to be offset of a CU with a non-zero low_pc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204377 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224257 91177308-0d34-0410-b5e6-96231b3b80d8

IR: Move MDLocation into place This commit moves `MDLocation`, finishing off PR21433. There's an accompanying clang commit for frontend testcases. I'll attach the testcase upgrade script I used to PR21433 to help out-of-tree frontends/backends. This changes the schema for `DebugLoc` and `DILocation` from: !{i32 3, i32 7, !7, !8} to: !MDLocation(line: 3, column: 7, scope: !7, inlinedAt: !8) Note that empty fields (line/column: 0 and inlinedAt: null) don't get printed by the assembly writer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226048 91177308-0d34-0410-b5e6-96231b3b80d8
