X86: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774

[X86] Optimization for replacing LEA with MOV at frame index elimination time Summary: Replace a LEA instruction of the form 'lea (%esp), %ebx' --> 'mov %esp, %ebx' MOV is preferable over LEA because usually there are more issue-slots available to execute MOVs than LEAs. Latest processors also support zero-latency MOVs. Fixes pr29022. Reviewers: hfinkel, delena, igorb, myatsina, mkuper Differential Revision: https://reviews.llvm.org/D24705 llvm-svn: 282385

Bias physical register immediate assignments The machine scheduler currently biases register copies to/from physical registers to be closer to their point of use / def to minimize their live ranges. This change extends this to also physical register assignments from immediate values. This causes a reduction in reduction in overall register pressure and minor reduction in spills and indirectly fixes an out-of-registers assertion (PR39391). Most test changes are from minor instruction reorderings and register name selection changes and direct consequences of that.

DI: Reverse direction of subprogram -> function edge. Previously, subprograms contained a metadata reference to the function they described. Because most clients need to get or set a subprogram for a given function rather than the other way around, this created unneeded inefficiency. For example, many passes needed to call the function llvm::makeSubprogramMap() to build a mapping from functions to subprograms, and the IR linker needed to fix up function references in a way that caused quadratic complexity in the IR linking phase of LTO. This change reverses the direction of the edge by storing the subprogram as function-level metadata and removing DISubprogram's function field. Since this is an IR change, a bitcode upgrade has been provided. Fixes PR23367. An upgrade script for textual IR for out-of-tree clients is attached to the PR.

Recommit r212203: Don't try to construct debug LexicalScopes hierarchy for functions that do not have top level debug information. Reverted by Eric Christopher (Thanks!) in r212203 after Bob Wilson reported LTO issues. Duncan Exon Smith and Aditya Nandakumar helped provide a reduced reproduction, though the failure wasn't too hard to guess, and even easier with the example to confirm. The assertion that the subprogram metadata associated with an llvm::Function matches the scope data referenced by the DbgLocs on the instructions in that function is not valid under LTO. In LTO, a C++ inline function might exist in multiple CUs and the subprogram metadata nodes will refer to the same llvm::Function. In this case, depending on the order of the CUs, the first intance of the subprogram metadata may not be the one referenced by the instructions in that function and the assertion will fail. A test case (test/DebugInfo/cross-cu-linkonce-distinct.ll) is added, the assertion removed and a comment added to explain this situation. This was then reverted again in r213581 as it caused PR20367. The root cause of this was the early exit in LiveDebugVariables meant that spurious DBG_VALUE intrinsics that referenced dead variables were not removed, causing an assertion/crash later on. The fix is to have LiveDebugVariables strip all DBG_VALUE intrinsics in functions without debug info as they're not needed anyway. Test case added to cover this situation (that occurs when a debug-having function is inlined into a nodebug function) in test/DebugInfo/X86/nodebug_with_debug_loc.ll Original commit message: If a function isn't actually in a CU's subprogram list in the debug info metadata, ignore all the DebugLocs and don't try to build scopes, track variables, etc. While this is possibly a minor optimization, it's also a correctness fix for an incoming patch that will add assertions to LexicalScopes and the debug info verifier to ensure that all scope chains lead to debug info for the current function. Fix up a few test cases that had broken/incomplete debug info that could violate this constraint. Add a test case where this occurs by design (inlining a debug-info-having function in an attribute nodebug function - we want this to work because /if/ the nodebug function is then inlined into a debug-info-having function, it should be fine (and will work fine - we just stitch the scopes up as usual), but should the inlining not happen we need to not assert fail either). llvm-svn: 213952

Reapply r257105 "[Verifier] Check that debug values have proper size" I originally reapplied this in 257550, but had to revert again due to bot breakage. The only change in this version is to allow either the TypeSize or the TypeAllocSize of the variable to be the one represented in debug info (hopefully in the future we can figure out how to encode the difference). Additionally, several bot failures following r257550, were due to optimizer bugs now fixed in r257787 and r257795. r257550 commit message was: ``` The follow extra changes were made to test cases: Manually making the variable be the actual type instead of a pointer to avoid pointer-size differences in generic code: LLVM :: DebugInfo/Generic/2010-03-24-MemberFn.ll LLVM :: DebugInfo/Generic/2010-04-06-NestedFnDbgInfo.ll LLVM :: DebugInfo/Generic/2010-05-03-DisableFramePtr.ll LLVM :: DebugInfo/Generic/varargs.ll Delete sizing information from debug info for the same reason (but the presence of the pointer was important to the test case): LLVM :: DebugInfo/Generic/restrict.ll LLVM :: DebugInfo/Generic/tu-composite.ll LLVM :: Linker/type-unique-type-array-a.ll LLVM :: Linker/type-unique-simple2.ll Fixing an incorrect DW_OP_deref LLVM :: DebugInfo/Generic/2010-05-03-OriginDIE.ll Fixing a missing DW_OP_deref LLVM :: DebugInfo/Generic/incorrect-variable-debugloc.ll Additionally, clang should no longer complain during bootstrap should no longer happen after r257534.

Recommit r212203: Don't try to construct debug LexicalScopes hierarchy for functions that do not have top level debug information. Reverted by Eric Christopher (Thanks!) in r212203 after Bob Wilson reported LTO issues. Duncan Exon Smith and Aditya Nandakumar helped provide a reduced reproduction, though the failure wasn't too hard to guess, and even easier with the example to confirm. The assertion that the subprogram metadata associated with an llvm::Function matches the scope data referenced by the DbgLocs on the instructions in that function is not valid under LTO. In LTO, a C++ inline function might exist in multiple CUs and the subprogram metadata nodes will refer to the same llvm::Function. In this case, depending on the order of the CUs, the first intance of the subprogram metadata may not be the one referenced by the instructions in that function and the assertion will fail. A test case (test/DebugInfo/cross-cu-linkonce-distinct.ll) is added, the assertion removed and a comment added to explain this situation. This was then reverted again in r213581 as it caused PR20367. The root cause of this was the early exit in LiveDebugVariables meant that spurious DBG_VALUE intrinsics that referenced dead variables were not removed, causing an assertion/crash later on. The fix is to have LiveDebugVariables strip all DBG_VALUE intrinsics in functions without debug info as they're not needed anyway. Test case added to cover this situation (that occurs when a debug-having function is inlined into a nodebug function) in test/DebugInfo/X86/nodebug_with_debug_loc.ll Original commit message: If a function isn't actually in a CU's subprogram list in the debug info metadata, ignore all the DebugLocs and don't try to build scopes, track variables, etc. While this is possibly a minor optimization, it's also a correctness fix for an incoming patch that will add assertions to LexicalScopes and the debug info verifier to ensure that all scope chains lead to debug info for the current function. Fix up a few test cases that had broken/incomplete debug info that could violate this constraint. Add a test case where this occurs by design (inlining a debug-info-having function in an attribute nodebug function - we want this to work because /if/ the nodebug function is then inlined into a debug-info-having function, it should be fine (and will work fine - we just stitch the scopes up as usual), but should the inlining not happen we need to not assert fail either). llvm-svn: 213952

[PR27284] Reverse the ownership between DICompileUnit and DISubprogram. Currently each Function points to a DISubprogram and DISubprogram has a scope field. For member functions the scope is a DICompositeType. DIScopes point to the DICompileUnit to facilitate type uniquing. Distinct DISubprograms (with isDefinition: true) are not part of the type hierarchy and cannot be uniqued. This change removes the subprograms list from DICompileUnit and instead adds a pointer to the owning compile unit to distinct DISubprograms. This would make it easy for ThinLTO to strip unneeded DISubprograms and their transitively referenced debug info. Motivation ---------- Materializing DISubprograms is currently the most expensive operation when doing a ThinLTO build of clang. We want the DISubprogram to be stored in a separate Bitcode block (or the same block as the function body) so we can avoid having to expensively deserialize all DISubprograms together with the global metadata. If a function has been inlined into another subprogram we need to store a reference the block containing the inlined subprogram. Attached to https://llvm.org/bugs/show_bug.cgi?id=27284 is a python script that updates LLVM IR testcases to the new format. http://reviews.llvm.org/D19034 <rdar://problem/25256815> llvm-svn: 266446

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).

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).

DebugInfo: Remove MDString-based type references Eliminate DITypeIdentifierMap and make DITypeRef a thin wrapper around DIType*. It is no longer legal to refer to a DICompositeType by its 'identifier:', and DIBuilder no longer retains all types with an 'identifier:' automatically. Aside from the bitcode upgrade, this is mainly removing logic to resolve an MDString-based reference to an actualy DIType. The commits leading up to this have made the implicit type map in DICompileUnit's 'retainedTypes:' field superfluous. This does not remove DITypeRef, DIScopeRef, DINodeRef, and DITypeRefArray, or stop using them in DI-related metadata. Although as of this commit they aren't serving a useful purpose, there are patchces under review to reuse them for CodeView support. The tests in LLVM were updated with deref-typerefs.sh, which is attached to the thread "[RFC] Lazy-loading of debug info metadata": http://lists.llvm.org/pipermail/llvm-dev/2016-April/098318.html llvm-svn: 267296

DebugInfo: Remove MDString-based type references Eliminate DITypeIdentifierMap and make DITypeRef a thin wrapper around DIType*. It is no longer legal to refer to a DICompositeType by its 'identifier:', and DIBuilder no longer retains all types with an 'identifier:' automatically. Aside from the bitcode upgrade, this is mainly removing logic to resolve an MDString-based reference to an actualy DIType. The commits leading up to this have made the implicit type map in DICompileUnit's 'retainedTypes:' field superfluous. This does not remove DITypeRef, DIScopeRef, DINodeRef, and DITypeRefArray, or stop using them in DI-related metadata. Although as of this commit they aren't serving a useful purpose, there are patchces under review to reuse them for CodeView support.

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label. In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.
