* This threads SectionName through the allocateCodeSection/allocateDataSection ↵Filip Pizlo2013-10-02
| | | | | | | | | | | | | | | | | | | | APIs, both in C++ and C land. It's useful for the memory managers that are allocating a section to know what the name of the section is. At a minimum, this is useful for low-level debugging - it's customary for JITs to be able to tell you what memory they allocated, and as part of any such dump, they should be able to tell you some meta-data about what each allocation is for. This allows clients that supply their own memory managers to do this. Additionally, we also envision the SectionName being useful for passing meta-data from within LLVM to an LLVM client. This changes both the C and C++ APIs, and all of the clients of those APIs within LLVM. I'm assuming that it's safe to change the C++ API because that API is allowed to change. I'm assuming that it's safe to change the C API because we haven't shipped the API in a release yet (LLVM 3.3 doesn't include the MCJIT memory management C API). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191804 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: In DIBuilder, the derived-from field of a DW_TAG_pointer_typeManman Ren2013-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | is updated to use DITypeRef. Move isUnsignedDIType and getOriginalTypeSize from DebugInfo.h to be static helper functions in DwarfCompileUnit. We already have a static helper function "isTypeSigned" in DwarfCompileUnit, and a pointer to DwarfDebug is added to resolve the derived-from field. All three functions need to go across link for derived-from fields, so we need to get hold of a type identifier map. A pointer to DwarfDebug is also added to DbgVariable in order to resolve the derived-from field. Debug info verifier is updated to check a derived-from field is a TypeRef. Verifier will not go across link for derived-from fields, in debug info finder, we go across the link to add derived-from fields to types. Function getDICompositeType is only used by dragonegg and since dragonegg does not generate identifier for types, we use an empty map to resolve the derived-from field. When printing a derived-from field, we use DITypeRef::getName to either return the type identifier or getName of the DIType. A paired commit at clang is required due to changes to DIBuilder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191800 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: remove duplication of DIEs when a DIE is part of the type systemManman Ren2013-10-01
| | | | | | | | | | | | | | | | | | | | | | | | and it is shared across CUs. We add a few maps in DwarfDebug to map MDNodes for the type system to the corresponding DIEs: MDTypeNodeToDieMap, MDSPNodeToDieMap, and MDStaticMemberNodeToDieMap. These DIEs can be shared across CUs, that is why we keep the maps in DwarfDebug instead of CompileUnit. Sometimes, when we try to add an attribute to a DIE, the DIE is not yet added to its owner yet, so we don't know whether we should use ref_addr or ref4. We create a worklist that will be processed during finalization to add attributes with the correct form (ref_addr or ref4). We add addDIEEntry to DwarfDebug to be a wrapper around DIE->addValue. It checks whether we know the correct form, if not, we update the worklist (DIEEntryWorklist). 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191792 91177308-0d34-0410-b5e6-96231b3b80d8

* [DebugInfo] Simplify and speedup .debug_aranges parsingAlexey Samsonov2013-10-01
| | | | | | | | | | | | Parsing .debug_aranges section now takes O(nlogn) operations instead of O(n^2), where "n" is the number of address ranges. With this change, the time required to symbolize an address from a random large Clang-generated binary drops from 165 seconds to 1.5 seconds.

* ARM: support interrupt attributeTim Northover2013-10-01

* [SystemZ] Optimize 32-bit FPR<->GPR moves for z196 and aboveRichard Sandiford2013-10-01
| | | | | | | | | Floats are stored in the high 32 bits of an FPR, and the only GPR<->FPR transfers are full-register transfers. This patch optimizes GPR<->FPR float transfers when the high word of a GPR is directly accessible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191764 91177308-0d34-0410-b5e6-96231b3b80d8
* Add non-blocking Wait() for launched processesTareq A. Siraj2013-10-01
| | | | | | | | | | | | | | | | | | - New ProcessInfo class to encapsulate information about child processes. - Generalized the Wait() to support non-blocking wait on child processes. - ExecuteNoWait() now returns a ProcessInfo object with information about the launched child. Users will be able to use this object to perform non-blocking wait. - ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution failed or not. These changes will allow users to implement basic process parallel tools.

* [SystemZ] Use upper words of GR64s for codegenRichard Sandiford2013-10-01
| | | | | | | | | | | | | | | This just adds the basics necessary for allocating the upper words to virtual registers (move, load and store). The move support is parameterised in a way that makes it easy to handle zero extensions, but the associated zero-extend patterns are added by a later patch. The easiest way of testing this seemed to be add a new "h" register constraint for high words. I don't expect the constraint to be useful in real inline asms, but it should work, so I didn't try to hide it behind an option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191739 91177308-0d34-0410-b5e6-96231b3b80d8
