* Add Foreach LoopDavid Greene2012-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add some data structures to represent for loops. These will be referenced during object processing to do any needed iteration and instantiation. Add foreach keyword support to the lexer. Add a mode to indicate that we're parsing a foreach loop. This allows the value parser to early-out when processing the foreach value list. Add a routine to parse foreach iteration declarations. This is separate from ParseDeclaration because the type of the named value (the iterator) doesn't match the type of the initializer value (the value list). It also needs to add two values to the foreach record: the iterator and the value list. Add parsing support for foreach. Add the code to process foreach loops and create defs based on iterator values. Allow foreach loops to be matched at the top level. When parsing an IDValue check if it is a foreach loop iterator for one of the active loops. If so, return a VarInit for it. Add Emacs keyword support for foreach. Add VIM keyword support for foreach. Add tests to check foreach operation. Add TableGen documentation for foreach. Support foreach with multiple objects. Support non-braced foreach body with one object. Do not require types for the foreach declaration. Assume the iterator type from the iteration list element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151164 91177308-0d34-0410-b5e6-96231b3b80d8

* Delete CodeInit and CodeRecTy from TableGen.Jakob Stoklund Olesen2012-01-131-87/+0
| | | | | | | The code type was always identical to a string anyway. Now it is simply a synonym. The code literal syntax [{...}] is still valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148092 91177308-0d34-0410-b5e6-96231b3b80d8
* Use uniqued StringInit pointers for lookups.Jakob Stoklund Olesen2012-01-131-10/+13
| | | | | | | This avoids a gazillion StringMap and dynamic_cast calls, making TableGen run 3x faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148091 91177308-0d34-0410-b5e6-96231b3b80d8
* Unweaken vtables as per ↵David Blaikie2011-12-203-0/+8

* Add NAME MemberDavid Greene2011-10-191-0/+7
| | | | | | | | Add a Value named "NAME" to each Record. This will be set to the def or defm name when instantiating multiclasses. This will replace the #NAME# processing hack once paste functionality is in place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142518 91177308-0d34-0410-b5e6-96231b3b80d8
* Call Record InitializerDavid Greene2011-10-191-0/+2
| | | | | | Call the common Record initializer code from constructors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142509 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Name Init Record ConstructorDavid Greene2011-10-191-0/+3
| | | | | | | Add a Record constructor that takes the Record name as an Init. This is more work toward paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142508 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix 80-col ViolationDavid Greene2011-10-191-1/+3
| | | | | | Split up the initializer list for Record to avoid 80-col issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142507 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix Name CheckDavid Greene2011-10-191-4/+4
| | | | | | Avoid a potential assert by asking for record names as strings explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142503 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix Name CheckDavid Greene2011-10-191-1/+1
| | | | | | | Record names may not be fully resolved at this point so ask for the record name as a string explicitly. This avoids a potential assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142502 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Record InitDavid Greene2011-10-191-0/+1
| | | | | | Add an init function to be shared among Record constructors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142501 91177308-0d34-0410-b5e6-96231b3b80d8
* Make Template Arg Names InitsDavid Greene2011-10-191-4/+10
| | | | | | | | Allow template arg names to be Inits. This is further work to implement paste as it allows template names to participate in paste operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142500 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Utility to Scope NamesDavid Greene2011-10-191-0/+10
| | | | | | | | Add a couple of utility functions to take a variable name and qualify it with the namespace of the enclosing class and/or multiclass. This is inpreparation for making template arg names first-class Inits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142498 91177308-0d34-0410-b5e6-96231b3b80d8
* Make VarInit Name an InitDavid Greene2011-10-191-3/+9
| | | | | | | | Make the VarInit name an Init itself. We need this to implement paste functionality so we can reference variables whose names are not yet completely resolved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142497 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Value AccessorsDavid Greene2011-10-191-2/+9
| | | | | | | | Add accessors to get Record values by Init name. This lets us look up Record values whose names are not yet fully resolved. More work toward paste. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142496 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Name Init AccessorsDavid Greene2011-10-191-0/+7
| | | | | | | Add a utility to get the name init and get the string representation of the name. This will be used for paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142495 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Init AccessorsDavid Greene2011-10-191-0/+4
| | | | | | | Add a couple of utility functions to get at the name init and return the name init as a string. This will be used for paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142494 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove MultidefsDavid Greene2011-10-071-17/+0
| | | | | | | | | | | | | | | | | | | Multidefs are a bit unwieldy and incomplete. Remove them in favor of another mechanism, probably for loops. Revert "Make Test More Thorough" Revert "Fix a typo." Revert "Vim Support for Multidefs" Revert "Emacs Support for Multidefs" Revert "Document Multidefs" Revert "Add a Multidef Test" Revert "Update Test for Multidefs" Revert "Process Multidefs" Revert "Parser Multidef Support" Revert "Lexer Support for Multidefs" Revert "Add Multidef Data Structures" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141378 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Multidef Data StructuresDavid Greene2011-10-051-0/+17
| | | | | | | | | | | Add a set of data structures and members analogous to those used for multiclass defs. These will represent a new kind of multiclass def: a multidef. The idea behind the multidef is to process a list of items and create a def record for each one inside the enclosing multiclass. This allows the user to dynamically create a set of defs based on the contents of a list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141230 91177308-0d34-0410-b5e6-96231b3b80d8
* Move TableGen's parser and entry point into a libraryPeter Collingbourne2011-10-015-0/+1801
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
