* DebugInfo: Only move types out of type units if they're named or type unitedDavid Blaikie2019-05-105-6/+99
| | | | | | | | | | | | | | | | | | Follow up to r359122, after a bug was reported in it - the original change too aggressively tried to move related types out of type units, which included unnamed types (like array types) which can't reasonably be declared-but-not-defined. A step beyond that is that some types in type units can be anonymous, if they are types with a name for linkage purposes (eg: "typedef struct { } x;"). So ensure those don't get turned into plain declarations (without signatures) because, lacking names, they can't be resolved to the definition. [Also include a fix for llvm-dwarfdump/libDebugInfoDWARF to pretty print types in type units] llvm-svn: 360458

* [clang-tidy] Change the namespace for llvm checkers from 'llvm' to 'llvm_check'Don Hinton2019-05-1012-54/+85
| | | | | | | | | | | | | | | | | | | | | | | Summary: Change the namespace for llvm checkers from 'llvm' to 'llvm_check', and modify add_new_check.py and rename_check.py to support the new namespace. Checker, file, and directory names remain unchanged. Used new version of rename_check.py to make the change in existing llvm checkers, but had to fix LLVMTidyModule.cpp and LLVMModuleTest.cpp by hand. The changes made by rename_check.py are idempotent, so if accidentally run multiple times, it won't do anything.

* Finish renaming CompileUnit -> UnitJan Kratochvil2019-05-1012-93/+85

Later patch will introduce DWARFTypeUnit which needs to be sometimes different from DWARFCompileUnit and it would be confusing without this renaming.

* [MC][ELF] Copy top 3 bits of st_other to .symver aliasesFangrui Song2019-05-102-0/+18
| | | | | | | | | | | | | | | On PowerPC64 ELFv2 ABI, the top 3 bits of st_other encode the local entry offset. A versioned symbol alias created by .symver should copy the bits from the source symbol. This partly fixes PR41048. A full fix needs tracking of .set assignments and updating st_other fields when finish() is called, see D56586.

Previously a declaration in a scheduler of ProcResource<1> would be treated identically to a declaration of ProcResource<2>.

* [X86] Avoid SFB - Fix inconsistent codegen with/without debug info Robert Lougher2019-05-102-2/+252
| | | | | | | | | | | | | | | | | | Fixes https://bugs.llvm.org/show_bug.cgi?id=40969 The functions findPotentiallyBlockedCopies and buildCopy are currently not accounting for the presence of debug instructions. In the former this results in the optimization not being trigerred, and in the latter results in inconsistent codegen.

* [InferAddressSpaces] Enhance the handling of cosntexpr.Michael Liao2019-05-103-4/+23
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: - Constant expressions may not be added in strict postorder as the forward instruction scan order. Thus, for a constant express (CE0), if its operand (CE1) is used in an previous instruction, they are not in postorder. However, different from `cloneInstructionWithNewAddressSpace`, `cloneConstantExprWithNewAddressSpace` doesn't bookkeep uninferred instructions for later resolving. That results in failure of inferring constant address. - This patch adds the support to infer constant expression operand recursively, since there won't be loop, if that operand is another constant expression.

* [DebugInfo] Use zero linenos for debug intrinsics when promoting dbg.declareJeremy Morse2019-05-103-9/+142
| | | | | | | | | | | | | | | | | | | | In certain circumstances, optimizations pick line numbers from debug intrinsic instructions as the new location for altered instructions. This is problematic because the line number of a debugging intrinsic is meaningless (it doesn't produce any machine instruction), only the scope information is valid. The result can be the line number of a variable declaration "leaking" into real code from debugging intrinsics, making the line table un-necessarily jumpy, and potentially different with / without variable locations. Fix this by using zero line numbers when promoting dbg.declare intrinsics into dbg.values: this is safe for debug intrinsics as their line numbers are meaningless, and reduces the scope for damage / misleading stepping when optimizations pick locations from the wrong place.
