| | | | | | | | | | Use 0 for the invalid buffer instead of -1/~0 and switch to unsigned representation to enable more idiomatic usage. Also introduce a trivial SourceMgr::getMainFileID() instead of hard-coding 0/1 to identify the main file. llvm-svn: 212398
* Revert "Introduce a string_ostream string builder facilty"Alp Toker2014-06-262-6/+8

* Introduce a string_ostream string builder faciltyAlp Toker2014-06-262-8/+6
| | | | | | | | | | | | | | | | | | | | string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. llvm-svn: 211749

* Use a vector of unique_ptrs to fix a memory leak introduced in r208179.Daniel Sanders2014-05-081-2/+2
| | | | | | | | | | | Also removed an inaccurate comment that stated that a DenseMap was used as storage for the ListInit*'s. It's currently using a FoldingSet. I expect there's a better way to fix this but I haven't found it yet. FoldingSet is incompatible with the Pool template and I'm not sure if FoldingSet can be safely replaced with a DenseMap of computed FoldingSetID's to ListInit*'s. llvm-svn: 208293
* [tablegen] Add !listconcat operator with the similar semantics as !strconcatDaniel Sanders2014-05-074-2/+36
| | | | | | | | | | | | | | | | | | | | Summary: It concatenates two or more lists. In addition to the !strconcat semantics the lists must have the same element type. My overall aim is to make it easy to append to Instruction.Predicates rather than override it. This can be done by concatenating lists passed as arguments, or by concatenating lists passed in additional fields.

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-2/+1
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-241-2/+2
| | | | | | | | | After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) llvm-svn: 202052

* [TableGen] Correctly generate implicit anonymous prototype defs in multiclassesHal Finkel2014-01-021-5/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 198348
* [TableGen] Use the same anonymous name as the prefix on all multiclass defsHal Finkel2014-01-022-2/+2
| | | | | | | | | | | | | | | | 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). llvm-svn: 198340
* TableGen: Generate valid identifiers for anonymous recordsAlp Toker2013-12-212-9/+11
| | | | | | | | | | 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. llvm-svn: 197869

* Remove some std stream usage from Support and TableGenReid Kleckner2013-08-061-4/+5

* Allow TableGen DAG arguments to be just a name.Jakob Stoklund Olesen2013-03-241-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | 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)>; llvm-svn: 177843
* Make sure TableGen exits with an error code after printing errors.Jakob Stoklund Olesen2013-03-202-2/+11
| | | | | | | | | | This makes it possible to report multiple errors in one invocation. There are already calls to PrintError in CodeGenDAGPatterns.cpp which previously would not cause TableGen to fail. <rdar://problem/13463339> llvm-svn: 177573

* tblgen: Diagnose duplicate includes.Sean Silva2013-02-074-10/+23
| | | | | | | | | | | | | | | A double inclusion will pretty much always be an error in TableGen, so there's no point going on just to die with "def already defined" or whatnot. I'm not too thrilled about the "public: ... private: ..." to expose the DependenciesMapTy, but I really didn't see a better way to keep that type centralized. It's a smell that indicates that some refactoring is needed to make this code more loosely coupled. This should avoid all bugs of the same nature as PR15189. llvm-svn: 174582
