* Write llvm-tblgen backends as functions instead of sub-classes.Jakob Stoklund Olesen2012-06-111-1/+4
| | | | | | | | | The TableGenBackend base class doesn't do much, and will be removed completely soon. Patch by Sean Silva! llvm-svn: 158311
* Fix 80 columns.Michael J. Spencer2012-06-011-3/+6
| | | | llvm-svn: 157788
* Add support for range expressions in TableGen foreach loops.Jakob Stoklund Olesen2012-05-241-15/+50
| | | | | | | | | | | | Like this: foreach i = 0-127 in ... Use braces for composite ranges: foreach i = {0-3,9-7} in ... llvm-svn: 157432
* Don't put TGParser scratch results in the output.Jakob Stoklund Olesen2012-05-241-2/+2
| | | | | | Only fully expanded Records should go into RecordKeeper. llvm-svn: 157431
* Simplify TGParser::ProcessForEachDefs.Jakob Stoklund Olesen2012-05-242-103/+72
| | | | | | Use static type checking. llvm-svn: 157430
* Emit memcmp directly from the StringMatcherEmitter.Benjamin Kramer2012-05-201-4/+4
| | | | | | | | | There should be no difference in the resulting binary, given a sufficiently smart compiler. However we already had compiler timeouts on the generated code in Intrinsics.gen, this hopefully makes the lives of slow buildbots a little easier. llvm-svn: 157161
* Move llvm-tblgen's StringMatcher into the TableGen library so it canDouglas Gregor2012-05-022-0/+150

* Remove stray semi-colon.Daniel Dunbar2012-02-281-1/+1
| | | | llvm-svn: 151629
* Add Foreach LoopDavid Greene2012-02-224-5/+262
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 151164

* Implement String Cast from IntegerDavid Greene2012-01-301-0/+5
| | | | | | Allow casts from integer to string. llvm-svn: 149273
* Fix Record Name ReferenceDavid Greene2012-01-281-1/+1
| | | | | | Get the record name though the init to avoid an assert. llvm-svn: 149153

* TblGen diagnostic for mismatched template instantiation.Jim Grosbach2012-01-201-0/+4
| | | | | | | | | | | | | | | | | | Providing a template argment to a non-templatized class was crashing tblgen. Add a diagnostic. For example, $ cat bug.td class A; def B : A<0> { } $ llvm-tblgen bug.td bug.td:3:11: error: template argument provided to non-template class def B : A<0> { ^ llvm-svn: 148565
* Removing unused default switch cases in switches over enums that already ↵David Blaikie2012-01-161-3/+0
| | | | | | | | account for all enumeration values explicitly. (This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them) llvm-svn: 148262
* Delete CodeInit and CodeRecTy from TableGen.Jakob Stoklund Olesen2012-01-132-33/+3
| | | | | | | The code type was always identical to a string anyway. Now it is simply a synonym. The code literal syntax [{...}] is still valid. llvm-svn: 148092
* Use uniqued StringInit pointers for lookups.Jakob Stoklund Olesen2012-01-132-21/+9
| | | | | | | This avoids a gazillion StringMap and dynamic_cast calls, making TableGen run 3x faster. llvm-svn: 148091

* ARM vldm and vstm VFP instructions can take a data type suffix.Jim Grosbach2011-11-111-1/+1
| | | | | | | | | | | | It's ignored by the assembler when present, but is legal syntax. Other instructions have something similar, but for some mnemonics it's only sometimes not significant, so this quick check in the parser will need refactored into something more robust soon-ish. This gets some basics working in the meantime. Partial for rdar://10435264 llvm-svn: 144422
* build: Add initial cut at LLVMBuild.txt files.Daniel Dunbar2011-11-031-0/+23

* 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<...> } llvm-svn: 142525
* 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. llvm-svn: 142524
* 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. llvm-svn: 142523
* 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. llvm-svn: 142522
* 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. llvm-svn: 142521
* 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. llvm-svn: 142520
* 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. llvm-svn: 142519
* Add NAME MemberDavid Greene2011-10-192-1/+6
| | | | | | | | 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. llvm-svn: 142518
* Fix Name AccessDavid Greene2011-10-191-2/+3
| | | | | | Get the Record name as a string explicitly to avoid asserts. llvm-svn: 142517

* Fix Name AccessDavid Greene2011-10-191-2/+3
| | | | | | Get the Record name as a string explicitly to avoid asserts. llvm-svn: 142515
* Fix Name AccessDavid Greene2011-10-191-1/+2
| | | | | | Get the Record name by string explicitly to avoid potential asserts. llvm-svn: 142514
* 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. llvm-svn: 142513
* 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. llvm-svn: 142512
* 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. llvm-svn: 142511
* 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. llvm-svn: 142510
* Fix Name AccessDavid Greene2011-10-191-1/+1
| | | | | | Ask for the Record name as a string explicitly to avoid a possible assert. llvm-svn: 142506
