* [TableGen] Correctly generate implicit anonymous prototype defs in multiclassesHal Finkel2014-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | Even within a multiclass, we had been generating concrete implicit anonymous defs when parsing values (generally in value lists). This behavior was incorrect, and led to errors when multiclass parameters were used in the parameter list of the implicit anonymous def. If we had some multiclass: multiclass mc<string n> { ... : SomeClass<SomeOtherClass<n> > The capture of the multiclass parameter 'n' would not work correctly, and depending on how the implicit SomeOtherClass was used, either TableGen would ignore something it shouldn't, or would crash. To fix this problem, when inside a multiclass, we generate prototype anonymous defs for implicit anonymous defs (just as we do for explicit anonymous defs). Within the multiclass, the current record prototype is populated with a node that is essentially: !cast<SomeOtherClass>(!strconcat(NAME, anon_value_name)). This is then resolved to the correct concrete anonymous def, in the usual way, when NAME is resolved during multiclass instantiation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198348 91177308-0d34-0410-b5e6-96231b3b80d8
* [TableGen] Use the same anonymous name as the prefix on all multiclass defsHal Finkel2014-01-02
| | | | | | | | | | | | | | | | TableGen had been generating a different name for an anonymous multiclass's NAME for every def in the multiclass. This had an unfortunate side effect: it was impossible to reference one def within the multiclass from another (in the parameter list, for example). By making sure we only generate an anonymous name once per multiclass (which, as it turns out, requires only changing the name parameter to reference type), we can now concatenate NAME within the multiclass with a def name in order to generate a reference to that def. This does not matter so much, in and of itself, but is necessary for a follow-up commit that will fix variable capturing in implicit anonymous multiclass defs (and that is important). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198340 91177308-0d34-0410-b5e6-96231b3b80d8

* TableGen: Generate valid identifiers for anonymous recordsAlp Toker2013-12-21
| | | | | | | | | | Backends like OptParserEmitter assume that record names can be used as valid identifiers. The period '.' in generated anonymous names broke that assumption, causing a build-time error and in practice forcing all records to be named. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197869 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in TableGen where the intrinsic function name recognizer could ↵Justin Holewinski2013-07-25
| | | | | | | | | | | | | | | | | mis-identify names if one was a prefix substring of the other For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal', TableGen was emitting matching code like: if (Name.startswith("llvm.nvvm.texsurf.handle")) ... if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ... We can never match "llvm.nvvm.texsurf.handle.internal" here because it will always be erroneously matched by the first condition. The fix is to sort the intrinsic names and emit them in reverse order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187119 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow TableGen DAG arguments to be just a name.Jakob Stoklund Olesen2013-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | DAG arguments can optionally be named: (dag node, node:$name) With this change, the node is also optional: (dag node, node:$name, $name) The missing node is treated as an UnsetInit, so the above is equivalent to: (dag node, node:$name, ?:$name) This syntax is useful in output patterns where we currently require the types of variables to be repeated: def : Pat<(subc i32:$b, i32:$c), (SUBCCrr i32:$b, i32:$c)>; This is preferable: def : Pat<(subc i32:$b, i32:$c), (SUBCCrr $b, $c)>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177843 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-work bit/bits value resolving in tblgenMichael Liao2012-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - This patch is inspired by the failure of the following code snippet which is used to convert enumerable values into encoding bits to improve the readability of td files. class S<int s> { bits<2> V = !if(!eq(s, 8), {0, 0}, !if(!eq(s, 16), {0, 1}, !if(!eq(s, 32), {1, 0}, !if(!eq(s, 64), {1, 1}, {?, ?})))); } Later, PR8330 is found to report not exactly the same bug relevant issue to bit/bits values. - Instead of resolving bit/bits values separately through resolveBitReference(), this patch adds getBit() for all Inits and resolves bit value by resolving plus getting the specified bit. This unifies the resolving of bit with other values and removes redundant logic for resolving bit only. In addition, BitsInit::resolveReferences() is optimized to take advantage of this origanization by resolving VarBitInit's variable reference first and then getting bits from it. - The type interference in '!if' operator is revised to support possible combinations of int and bits/bit in MHS and RHS. - As there may be illegal assignments from integer value to bit, says assign 2 to a bit, but we only check this during instantiation in some cases, e.g. bit V = !if(!eq(x, 17), 0, 2); Verbose diagnostic message is generated when invalid value is resolveed to help locating the error. - PR8330 is fixed as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163360 91177308-0d34-0410-b5e6-96231b3b80d8
* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-02
| | | | | | | | | | | | | | | | | | | | | | | | This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8

* Add Foreach LoopDavid Greene2012-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Teach TableGen to evaluate DAG expressions as set operations.Jakob Stoklund Olesen2011-06-04
| | | | | | | | | | | | | | | | | A TableGen backend can define how certain classes can be expanded into ordered sets of defs, typically by evaluating a specific field in the record. The SetTheory class can then evaluate DAG expressions that refer to these named sets. A number of standard set and list operations are predefined, and the backend can add more specialized operators if needed. The -print-sets backend is used by SetTheory.td to provide examples. This is intended to simplify how register classes are defined: def GR32_NOSP : RegisterClass<"X86", [i32], 32, (sub GR32, ESP)>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132621 91177308-0d34-0410-b5e6-96231b3b80d8

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
