2011-02-04Silence uninitialized value warnings.David Greene
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124869 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-01[AVX] Implement EnforceSmallerThan for mixed int/fp type lists. ThisDavid Greene
makes type checking for extract_subvector and insert_subvector more robust and will allow stricter typechecking of more patterns in the future. This change handles int and fp as disjoint sets so that it will enforce integer types to be smaller than the largest integer type and fp types to be smaller than the largest fp type. There is no attempt to check type sizes across the int/fp sets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124672 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-24[AVX] Add type checking support for vector/subvector type constraints.David Greene
This will be used to check patterns referencing a forthcoming INSERT_SUBVECTOR SDNode. INSERT_SUBVECTOR in turn is very useful for matching to VINSERTF128 instructions and complements the already existing EXTRACT_SUBVECTOR SDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124145 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-24Add the SubRegIndex TableGen class.Jakob Stoklund Olesen
This is the beginning of purely symbolic subregister indices, but we need a bit of jiggling before the explicit numeric indices can be completely removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104492 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28improve type checking of SDNode operand count. This rejects all casesChris Lattner
where an incorrect number of operands is provided to an sdnode instead of just a few cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99761 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28finally remove the immAllOnesV_bc/immAllZerosV_bc patternsChris Lattner
and those derived from them. These are obnoxious because they were written as: PatLeaf<(bitconvert). Not having an argument was foiling adding better type checking for operand count matching up with what was required (in this case, bitconvert always requires an operand!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99759 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4), Chris Lattner
transforming it into (add (i32 GPR), 4). This allows us to write type generic multi patterns and have tblgen automatically drop the bitconvert in the case when the types align. This allows us to fold an extra load in the changed testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99756 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27fix CodeGenTarget::getRegisterVTs to not return the Chris Lattner
same vt multiple times for a register. For example, ECX is in 5 different i32 reg classes, just return 1 i32 instead of 5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99727 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27hoist some funky logic into CodeGenInstructionChris Lattner
from two places in CodeGenDAGPatterns.cpp, and use it in DAGISelMatcherGen.cpp instead of using an incorrect predicate that happened to get lucky on our current targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99726 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27continue pushing tblgen's support for nodes with multipleChris Lattner
results forward. We can now handle an instruction that produces one implicit def and one result instead of one or the other when not at the root of the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99725 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19major surgery on tblgen: generalize TreePatternNodeChris Lattner
to maintain a list of types (one for each result of the node) instead of a single type. There are liberal hacks added to emulate the old behavior in various situations, but they can start disolving now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98999 91177308-0d34-0410-b5e6-96231b3b80d8

like this: def : Pat<(add ...), (FOOINST)>; When fooinst only has a single implicit def (e.g. to R1). This will be handled as if written as (set R1, (FOOINST ...)) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98897 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-15Completely rewrite tblgen's type inference mechanism,Chris Lattner
changing the primary datastructure from being a "std::vector<unsigned char>" to being a new TypeSet class that actually has (gasp) invariants! This changes more things than I remember, but one major innovation here is that it enforces that named input values agree in type with their output values. This also eliminates code that transparently assumes (in some cases) that SDNodeXForm input/output types are the same, because this is wrong in many case. This also eliminates a bug which caused a lot of ambiguous patterns to go undetected, where a register class would sometimes pick the first possible type, causing an ambiguous pattern to get arbitrary results. With all the recent target changes, this causes no functionality change! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98534 91177308-0d34-0410-b5e6-96231b3b80d8
