* DebugInfo: regenerate test case from Clang to adjust for fixes/improvementsDavid Blaikie2013-11-011-87/+64
| | | | | | | | | | | I hit some problems with future work due to the member subprogram of 'a_b's type having a subprogram (an implicit default ctor, !52 in the pre-commit source) with no name. Clang now generates a name for such a function but in this case doesn't even emit debug info for it as it is unused (Clang never emits the body of the ctor, instead just emitting memset if needed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193892 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Make pubnames header printing similar to unit header printingDavid Blaikie2013-11-013-14/+4
| | | | | | | | | | | | | | | In a failed attempt to allow the gnu-public-names.ll test case to not hardcode the size of the unit that the pubnames section referred to I've at least managed to have unit headers and pubnames headers print out in a similar style. This failed to achieve the desired goal because the header in a unit specifies the length of the unit without the length element of the header whereas the length in the pubnames includes this element, so the numbers are off by 4 bytes. I don't know of any arithmetic powers in FileCheck so the test case can't simply say "CU_LENGTH + 4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193872 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: remove duplication of DIEs when a DIE can be shared across CUs.Manman Ren2013-10-311-0/+70
| | | | | | | | | | | | | | | | | | | | We add a map in DwarfDebug to map MDNodes that are shareable across CUs to the corresponding DIEs: MDTypeNodeToDieMap. These DIEs can be shared across CUs, that is why we keep the maps in DwarfDebug instead of CompileUnit. We make the assumption that if a DIE is not added to an owner yet, we assume it belongs to the current CU. Since DIEs for the type system are added to their owners immediately after creation, and other DIEs belong to the current CU, the assumption should be true. A testing case is added to show that we only create a single DIE for a type MDNode and we use ref_addr to refer to the type DIE. We also add a testing case to show ref_addr relocations for non-darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193779 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Hash DW_FORM_GNU_str_index as a string.David Blaikie2013-10-211-2/+2
| | | | | | | | | | Found while adding type safety to the various DWARF enumerations (form, attribute, tag, etc) that caused Clang to warn on an incompletely covered switch.

| | | | | | | | | | | | | | | | 1) Make sure we emit static member variables by checking at the end of createGlobalVariableDIE rather than piecemeal in the function. (As a note, createGlobalVariableDIE needs rewriting.) 2) Make sure we use the definition rather than declaration DIE for two things: a) determining linkage for gnu pubnames, and b) as the address of the DIE for global variables. (As a note, createGlobalVariableDIE really needs rewriting.) Adjust the testcase to make sure we're checking the correct DIEs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192761 91177308-0d34-0410-b5e6-96231b3b80d8
* Enable MI Sched for x86.Andrew Trick2013-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This changes the SelectionDAG scheduling preference to source order. Soon, the SelectionDAG scheduler can be bypassed saving a nice chunk of compile time. Performance differences that result from this change are often a consequence of register coalescing. The register coalescer is far from perfect. Bugs can be filed for deficiencies. On x86 SandyBridge/Haswell, the source order schedule is often preserved, particularly for small blocks. Register pressure is generally improved over the SD scheduler's ILP mode. However, we are still able to handle large blocks that require latency hiding, unlike the SD scheduler's BURR mode. MI scheduler also attempts to discover the critical path in single-block loops and adjust heuristics accordingly. The MI scheduler relies on the new machine model. This is currently unimplemented for AVX, so we may not be generating the best code yet. Unit tests are updated so they don't depend on SD scheduling heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192750 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case (shown in the attached test) where a member function definition was emitted into debug info the following could occur: 1) build the debug info for the member function definition 2) in (1), build the debug info for the member function declaration 3) construct and add the member function declaration DIE 4) add it to its context 5) build its context (the type it is a member of) 6) construct the members and add them to the type 7) except don't add member functions because "getOrCreateSubprogram" adds the function to its parent anyway 8) except we're only partway through building this subprogram declaration so it hasn't been added yet - but we returned the partially constructed DIE (since it's already in the MDNode->DIE mapping to avoid infinitely recursing trying to create the member function DIE) 9) once the type is constructed, add the member function to it 10) now the members are out of order (the member function being defined is listed as the last member, even though it was declared as the first) To avoid this, construct the context of the subprogram DIE before we query to see if it exists. That way we never end up creating it before creating its context and ending up in this situation. Alternatively, the type construction that visits/builds all the members could call something like getOrCreateSubprogram, but that doesn't ever do the "add to context" step. Then the type building code would always be responsible for adding members (and the subprogram "addToContextDIE" would no-op because the context building would have added the subprogram declaration to the type/context DIE already). (the test cases updated were overly-sensitive to offsets or abbreviation numbers. We don't have a nice way to make these tests more robust as yet - multiline FileCheck matches would be required) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191939 91177308-0d34-0410-b5e6-96231b3b80d8
