* SelectionDAG: Don't use MVT::Other to determine legality of ISD::SELECT_CCTom Stellard2014-06-10
| | | | | | | | | | | | | The SelectionDAG bad a special case for ISD::SELECT_CC, where it would allow targets to specify: setOperationAction(ISD::SELECT_CC, MVT::Other, Expand); to indicate that they wanted to expand ISD::SELECT_CC for all types. This wasn't applied correctly everywhere, and it makes writing new DAG patterns with ISD::SELECT_CC difficult. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210541 91177308-0d34-0410-b5e6-96231b3b80d8

* TableGen: permit non-leaf ComplexPattern usesTim Northover2014-05-20
| | | | | | | | | | | | | | | | | | This allows the results of a ComplexPattern check to be distributed to separate named Operands, instead of the current system where all results must apply (and match perfectly) with a single Operand. For example, if "some_addrmode" is a ComplexPattern producing two results, you can write: def : Pat<(load (some_addrmode GPR64:$base, imm:$offset)), (INST GPR64:$base, imm:$offset)>; This should allow neater instruction definitions in TableGen that don't put all possible aspects of addressing into a single operand, but are still usable with relatively simple C++ CodeGen idioms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209206 91177308-0d34-0410-b5e6-96231b3b80d8

In a few targets this was already done pretty consistently, but it wasn't done *really* consistently anywhere. It is strictly cleaner IMO and necessary in a bunch of places where the DEBUG_TYPE is referenced from the generated code. Consistency with the necessary places trumps. Hopefully the build bots are OK with the movement of intrin.h... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206838 91177308-0d34-0410-b5e6-96231b3b80d8
* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206822 91177308-0d34-0410-b5e6-96231b3b80d8

* [C++11] Add range based accessors for the Use-Def chain of a Value.Chandler Carruth2014-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires a number of steps. 1) Move value_use_iterator into the Value class as an implementation detail 2) Change it to actually be a *Use* iterator rather than a *User* iterator. 3) Add an adaptor which is a User iterator that always looks through the Use to the User. 4) Wrap these in Value::use_iterator and Value::user_iterator typedefs. 5) Add the range adaptors as Value::uses() and Value::users(). 6) Update *all* of the callers to correctly distinguish between whether they wanted a use_iterator (and to explicitly dig out the User when needed), or a user_iterator which makes the Use itself totally opaque. Because #6 requires churning essentially everything that walked the Use-Def chains, I went ahead and added all of the range adaptors and switched them to range-based loops where appropriate. Also because the renaming requires at least churning every line of code, it didn't make any sense to split these up into multiple commits -- all of which would touch all of the same lies of code. The result is still not quite optimal. The Value::use_iterator is a nice regular iterator, but Value::user_iterator is an iterator over User*s rather than over the User objects themselves. As a consequence, it fits a bit awkwardly into the range-based world and it has the weird extra-dereferencing 'operator->' that so many of our iterators have. I think this could be fixed by providing something which transforms a range of T&s into a range of T*s, but that *can* be separated into another patch, and it isn't yet 100% clear whether this is the right move. However, this change gets us most of the benefit and cleans up a substantial amount of code around Use and User. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203364 91177308-0d34-0410-b5e6-96231b3b80d8
* Replace PROLOG_LABEL with a new CFI_INSTRUCTION.Rafael Espindola2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | The old system was fairly convoluted: * A temporary label was created. * A single PROLOG_LABEL was created with it. * A few MCCFIInstructions were created with the same label. The semantics were that the cfi instructions were mapped to the PROLOG_LABEL via the temporary label. The output position was that of the PROLOG_LABEL. The temporary label itself was used only for doing the mapping. The new CFI_INSTRUCTION has a 1:1 mapping to MCCFIInstructions and points to one by holding an index into the CFI instructions of this function. I did consider removing MMI.getFrameInstructions completelly and having CFI_INSTRUCTION own a MCCFIInstruction, but MCCFIInstructions have non trivial constructors and destructors and are somewhat big, so the this setup is probably better. The net result is that we don't create temporary labels that are never used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203204 91177308-0d34-0410-b5e6-96231b3b80d8
