* Update DebugInfo interface to use metadata, instead of special named ↵Devang Patel2009-08-251-4/+4
| | | | | | | | llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!) llvm-svn: 79977

* Allow targets to specify their choice of calling conventions perAnton Korobeynikov2009-08-141-1/+1
| | | | | | | | | | libcall. Take advantage of this in the ARM backend to rectify broken choice of CC when hard float is in effect. PIC16 may want to see if it could be of use in MakePIC16Libcall, which works unchanged. Patch by Sandeep! llvm-svn: 79033

* Major calling convention code refactoring.Dan Gohman2009-08-051-39/+5
| | | | | | | | | | | | | | | | | | | Instead of awkwardly encoding calling-convention information with ISD::CALL, ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering provides three virtual functions for targets to override: LowerFormalArguments, LowerCall, and LowerRet, which replace the custom lowering done on the special nodes. They provide the same information, but in a more immediately usable format. This also reworks much of the target-independent tail call logic. The decision of whether or not to perform a tail call is now cleanly split between target-independent portions, and the target dependent portion in IsEligibleForTailCallOptimization. This also synchronizes all in-tree targets, to help enable future refactoring and feature work. llvm-svn: 78142

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-16/+16
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* Implement support for promotion of AND/OR/XOR on integer types.Jakob Stoklund Olesen2009-07-121-8/+19
| | | | | | The blackfin processor has a legal i16 type, but only logic operations on i32. llvm-svn: 75419
* Fix types in PromoteNode handling of CTPOP and friends.Jakob Stoklund Olesen2009-07-121-3/+3
| | | | llvm-svn: 75418
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-13/+13
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Convert more assert(0)+abort() -> LLVM_UNREACHABLE,Torok Edwin2009-07-111-4/+4
| | | | | | and abort()/exit() -> llvm_report_error(). llvm-svn: 75363
* Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned Eli Friedman2009-07-091-1/+5
| | | | | | | | | value. Adjust other code to deal with that correctly. Make DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of this new flexibility to simplify the code and make it deal with unusual vectors (like <4 x i1>) correctly. Fixes PR3037. llvm-svn: 75176
* Thread LLVMContext through MVT and related parts of SDISel.Owen Anderson2009-07-091-11/+17
| | | | llvm-svn: 75153
* Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller2009-07-031-2/+2
| | | | | | | | | | | arguments in a vararg call. With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack. The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list. llvm-svn: 74764
* This increases the maximum for MVT::LAST_VALUETYPEDavid Greene2009-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change doubles the allowable value for MVT::LAST_VALUETYPE. It does this by doing several things. 1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a value of 64. This value contains the current maximum for the MVT::LAST_VALUETYPE. 2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE" 3. Changes the dimension of the ValueTypeActions from 2 elements to four elements and adds comments ahead of the declaration indicating the it is "(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2". This at least lets us find what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets changed. 4. Adds initializers for the new elements of ValueTypeActions. This does NOT add any types in MVT. That would be done separately. This doubles the size of ValueTypeActions from 64 bits to 128 bits and gives us the freedom to add more types for AVX. llvm-svn: 74110
* Add some generic expansion logic for SMULO and UMULO. Fixes UMULO Eli Friedman2009-06-161-0/+47
| | | | | | | | support for x86, and UMULO/SMULO for many architectures, including PPC (PR4201), ARM, and Cell. The resulting expansion isn't perfect, but it's not bad. llvm-svn: 73477
* Slightly generalize the code that handles shuffles of consecutive loads Eli Friedman2009-06-071-78/+37
| | | | | | | | | | | on x86 to handle more cases. Fix a bug in said code that would cause it to read past the end of an object. Rewrite the code in SelectionDAGLegalize::ExpandBUILD_VECTOR to be a bit more general. Remove PerformBuildVectorCombine, which is no longer necessary with these changes. In addition to simplifying the code, with this change, we can now catch a few more cases of consecutive loads. llvm-svn: 73012
