2011-10-01Move TableGen's parser and entry point into a libraryPeter Collingbourne
This is the first step towards splitting LLVM and Clang's tblgen executables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140951 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Better Error ReportingDavid Greene
Report missing template arguments more helpfully by supplying the name of the missing argument in the error message. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140034 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10Make Record Name an InitDavid Greene
Use an Init (ultimately a StringInit) to represent the Record name. This allows the name to be composed by standard TableGen operators. This will enable us to get rid of the ugly #NAME# hack processing and naturally replace it with operators. It also increases flexibility and power of the TableGen language by allowing record identifiers to be computed dynamically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137232 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Unconstify InitsDavid Greene
Remove const qualifiers from Init references, per Chris' request. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136531 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Create Inits Via Factory MethodDavid Greene
Replace uses of new *Init with *Init::get. This hides the allocation implementation so that we can unique Inits in various ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136486 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Constify InitsDavid Greene
Make references to Inits const everywhere. This is the final step before making them unique. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136485 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Remove Mutating Members from InitsDavid Greene
Get rid of all Init members that modify internal state. This is in preparation for making references to Inits const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136483 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Intern all RecTy subclass instances to avoid duplicates.Jakob Stoklund Olesen
Make all of the RecTy constructors private, and use get() factory methods instead. Return singleton instances when it makes sense. ListTy instance pointers are stored in the element RecTy instance. BitsRecTy instance pointers, one per length, are stored in a static vector. Also unique DefInit instances. A Record has a unique DefInit which has a unique RecordRecTy instance. This saves some 200k-300k RecTy allocations when parsing ARM.td. It reduces TableGen's heap usage by almost 50%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135399 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-11Revert r134921, 134917, 134908 and 134907. They're causing failuresEric Christopher

2011-07-11Use get(0 Instead of Create()David Greene
Respond to some feedback asking for a name change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134921 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-11[AVX] Make Inits FoldableDavid Greene
Manage Inits in a FoldingSet. This provides several benefits: - Memory for Inits is properly managed - Duplicate Inits are folded into Flyweights, saving memory - It enforces const-correctness, protecting against certain classes of bugs The above benefits allow Inits to be used in more contexts, which in turn provides more dynamism to TableGen. This enhanced capability will be used by the AVX code generator to a fold common patterns together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134907 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-13Add support for using the `!if' operator when initializing variables:Bill Wendling
class A<bit a, bits<3> x, bits<3> y> { bits<3> z; let z = !if(a, x, y); } The variable z will get the value of x when 'a' is 1 and 'y' when a is '0'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121666 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31fix the !eq operator in tblgen to return a bit instead of an int.Chris Lattner
Use this to make the X86 and ARM targets set isCodeGenOnly=1 automatically for their instructions that have Format=Pseudo, resolving a hack in tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117862 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-06Generalize tblgen's dag parsing logic to handle arbitrary expressionsChris Lattner
as the operator of the dag. Specifically, this allows parsing things like (F.x 4) in addition to just (a 4). Unfortunately, this runs afoul of an idiom being used by llvmc. It is using dags like (foo [1,2,3]) to represent a list of stuff being passed into foo. With this change, this is parsed as a [1,2,3] subscript on foo instead of being the first argument to the dag. Cope with this in the short term by requiring a "-llvmc-temp-hack" argument to tblgen to get the old parsing behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115742 91177308-0d34-0410-b5e6-96231b3b80d8
