Use .cfi_sections to put the unwind info in .debug_frame when possible. With this clang will use .debug_frame in, for example, clang -g -c -m32 test.c This matches gcc's behaviour. It looks like .debug_frame is a bit bigger than .eh_frame, but has the big advantage of not being allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131140 91177308-0d34-0410-b5e6-96231b3b80d8 2011-05-10 18:39:09 +00:00

Upgrade tests to the latest debug info format. Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8 2013-03-08 00:23:31 +00:00			`!llvm.dbg.cu = !{!2}`
Debug Info: update testing cases to specify the debug info version number. We are going to drop debug info without a version number or with a different version number, to make sure we don't crash when we see bitcode files with different debug info metadata format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195504 91177308-0d34-0410-b5e6-96231b3b80d8 2013-11-22 21:49:45 +00:00			`!llvm.module.flags = !{!7}`
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.
