2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
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"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-12Implement support for promotion of AND/OR/XOR on integer types.Jakob Stoklund Olesen
The blackfin processor has a legal i16 type, but only logic operations on i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75419 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-12Fix types in PromoteNode handling of CTPOP and friends.Jakob Stoklund Olesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75418 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11Convert more assert(0)+abort() -> LLVM_UNREACHABLE,Torok Edwin

2009-07-09Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned Eli Friedman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75176 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-09Thread LLVMContext through MVT and related parts of SDISel.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75153 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74764 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-24This increases the maximum for MVT::LAST_VALUETYPEDavid Greene
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74110 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16Add some generic expansion logic for SMULO and UMULO. Fixes UMULO Eli Friedman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Slightly generalize the code that handles shuffles of consecutive loads Eli Friedman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73012 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-06Fix the expansion for CONCAT_VECTORS so that it doesn't create illegal Eli Friedman
types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72993 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-28Re-commit r72514 and r72516 with a fixed version of BR_CC lowering. Eli Friedman
This patch removes some special cases for opcodes and does a bit of cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72536 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-28Remove special cases for more opcodes.Eli Friedman
This is basically the end of this series of patches for LegalizeDAG; the remaining special cases can't be removed without more infrastructure work. There's a FIXME for each relevant opcode near the beginning of SelectionDAGLegalize::LegalizeOp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72514 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-24Rewrite ISD::FCOPYSIGN lowering to never use i64. Not really ideal, but Eli Friedman
it's late, and I don't have any better ideas at the moment. Fixes PR4257. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72363 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-24Remove checks of getTypeAction from LegalizeOp; we already assert that Eli Friedman

2009-05-23Add a proper implementation of EXTRACT_SUBVECTOR legalization that Eli Friedman
doesn't split legal vector operands. This is necessary because the type legalization (and therefore, vector splitting) code will be going away soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72349 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-11When scalarizing a vector BITCAST, check whether the operand has vectorDan Gohman
type, rather than assume that it does. If the operand is not vector, it shouldn't be run through ScalarizeVectorOp. This fixes one of the testcases in PR3886. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71453 91177308-0d34-0410-b5e6-96231b3b80d8
