* Improve code generation for vselect on SSE2:Nadav Rotem2011-10-192-13/+20
| | | | | | | | | | | When checking the availability of instructions using the TLI, a 'promoted' instruction IS available. It means that the value is bitcasted to another type for which there is an operation. The correct check for the availablity of an instruction is to check if it should be expanded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142542 91177308-0d34-0410-b5e6-96231b3b80d8

* Use literal pool loads instead of MOVW/MOVT for materializing global ↵James Molloy2011-10-192-3/+33
| | | | | | | | | | | | | | | | addresses when optimizing for size. On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is codesize including literal pools. The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries. Fixes PR11087. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142530 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement PasteDavid Greene2011-10-193-28/+67
| | | | | | | | | | | | | | Add a paste operator '#' to take two identifier-like strings and joint them. Internally paste gets represented as a !strconcat() with any necessary casts to string added. This will be used to implement basic for loop functionality as in: for i = [0, 1, 2, 3, 4, 5, 6, 7] { def R#i : Register<...> } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142525 91177308-0d34-0410-b5e6-96231b3b80d8
* Process NAMEDavid Greene2011-10-191-8/+35
| | | | | | | During multiclass def instantiation, replace NAME in any expressions with the value of the def or defm ID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142524 91177308-0d34-0410-b5e6-96231b3b80d8
* Process Defm Prefix as InitDavid Greene2011-10-192-20/+40
| | | | | | | Parse and process a defm prefix as an Init expression. This allows paste operations to create defm prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142523 91177308-0d34-0410-b5e6-96231b3b80d8
* Parse Def ID as ValueDavid Greene2011-10-192-14/+42
| | | | | | | Allow def and defm IDs to be general values. We need this for paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142522 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't Parse Object Body as a NameDavid Greene2011-10-191-0/+4
| | | | | | | | Stop parsing a value if we are in name parsing mode and we see a left brace. A left brace indicates the start of an object body when we are parsing a name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142521 91177308-0d34-0410-b5e6-96231b3b80d8
* Use Parse ModeDavid Greene2011-10-191-2/+9
| | | | | | | Augment the value parser to respect the parse mode and not error if an ID doesn't map to an object and we are in name parsing mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142520 91177308-0d34-0410-b5e6-96231b3b80d8
* Make ID Parsing More FlexibleDavid Greene2011-10-192-10/+26
| | | | | | | | | | | | | | | | | | | Add a mode control to value and ID parsers. The two modes are: - Parse a value. Expect the parsed ID to map to an existing object. - Parse a name. Expect the parsed ID to not map to any existing object. The first is used when parsing an identifier to be looked up, for example a record field or template argument. The second is used for parsing declarations. Paste functionality implies that declarations can contain arbitrary expressions so we need to be able to call into the general value parser to parse declarations with paste operators. So we need a way to parse a value-like thing without expecting that the result will map to some existing object. This parse mode provides that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142519 91177308-0d34-0410-b5e6-96231b3b80d8
* Add NAME MemberDavid Greene2011-10-195-2/+16
| | | | | | | | 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

* Disambiguate Numbers and IdentifiersDavid Greene2011-10-191-1/+37
| | | | | | | | Use lookahead to determine whether a number is really a number or is part of something forming an identifier. This won't come into play until the paste operator is recognized as a unique token. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142513 91177308-0d34-0410-b5e6-96231b3b80d8
* Add PeekDavid Greene2011-10-192-0/+5
| | | | | | | | | | | | | Add a peek function to let the Lexer look at a character arbitrarily far ahead in the stream without consuming anything. We need this to disambiguate numbers and operands of a paste operation. For example: def foo#8i Without lookahead the lexer will treat '8' as a number rather than as part of a string to be pasted to form an identifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142512 91177308-0d34-0410-b5e6-96231b3b80d8
* Resolve Record NamesDavid Greene2011-10-191-0/+6
| | | | | | | When resolving Record values, be sure to update the Record name as it may contain references to the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142511 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow Names Changes on Unregistered RecordsDavid Greene2011-10-191-4/+3
| | | | | | | | | | | Add Record names to be changed even on Records that aren't yet registered. We need to be able to do this for paste functionality because we do not want to register def names before they are unique and that can only happen once all paste operations are done. This change lets us update Record names formed by paste operations and register the result later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142510 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 Greene2011-10-191-1/+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 Greene2011-10-192-0/+5
| | | | | | 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 Greene2011-10-194-38/+53
| | | | | | | | 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
* Let SetValue Take and Init NameDavid Greene2011-10-192-9/+17
| | | | | | | Convert SetValue to take the value name as an Init. This allows us to set values for variables whose names are not yet fully resolved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142499 91177308-0d34-0410-b5e6-96231b3b80d8
* Add Utility to Scope NamesDavid Greene2011-10-192-0/+46
| | | | | | | | 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 Greene2011-10-192-4/+22
| | | | | | | | 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 Greene2011-10-192-2/+21
| | | | | | | | 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
