* Replace size method call of containers to empty method where appropriateAlexander Kornienko2015-01-151-1/+1
| | | | | | | | | | | | | | | | This patch was generated by a clang tidy checker that is being open sourced. The documentation of that checker is the following: /// The emptiness of a container should be checked using the empty method /// instead of the size method. It is not guaranteed that size is a /// constant-time function, and it is generally more efficient and also shows /// clearer intent to use empty. Furthermore some containers may implement the /// empty method but not implement the size method. Using empty whenever /// possible makes it easier to switch to another container in the future.

| | | | | | | | | | ownership and deletion of the values." Upon further review I think the MultiClass is being copied into the map instead of being moved due to the copy constructor on the nested Record type. This ultimately got exposed when the vector in DefPrototype vector was changed to hold unique_ptrs in another commit. This caused gcc 4.7 to fail due to the use of the copy constructor on unique_ptr with the error pointing back to one of the insert calls from this commit. Not sure why clang was able to build. This reverts commit 710cdf729f84b428bf41aa8d32dbdb35fff79fde. llvm-svn: 222971

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By class-instance values I mean 'Class<Arg>' in 'Class<Arg>.Field' or in 'Other<Class<Arg>>' (syntactically s SimpleValue). This is to differentiate from unnamed/anonymous record definitions (syntactically an ObjectBody) which are not affected by this change. Consider the testcase: class Struct<int i> { int I = !shl(i, 1); int J = !shl(I, 1); } class Class<Struct s> { int Class_J = s.J; } multiclass MultiClass<int i> { def Def : Class<Struct<i>>; } defm Defm : MultiClass<2>; Before this fix, DefmDef.Class_J yields !shl(I, 1) instead of 8. This is the sequence of events. We start with this: multiclass MultiClass<int i> { def Def : Class<Struct<i>>; } During ParseDef the anonymous object for the class-instance value is created: multiclass Multiclass<int i> { def anonymous_0 : Struct<i>; def Def : Class<NAME#anonymous_0>; } Then class Struct<i> is added to anonymous_0. Also Class<NAME#anonymous_0> is added to Def: multiclass Multiclass<int i> { def anonymous_0 { int I = !shl(i, 1); int J = !shl(I, 1); } def Def { int Class_J = NAME#anonymous_0.J; } } So far so good but then we move on to instantiating this in the defm by substituting the template arg 'i'. This is how the anonymous prototype looks after fully instantiating. defm Defm = { def Defmanonymous_0 { int I = 4; int J = !shl(I, 1); } Note that we only resolved the reference to the template arg. The non-template-arg reference in 'J' has not been resolved yet. Then we go on to instantiating the Def prototype: def DefmDef { int Class_J = NAME#anonymous_0.J; } Which is resolved to Defmanonymous_0.J and then to !shl(I, 1). When we fully resolve each record in a defm, Defmanonymous_0.J does get set to 8 but that's too late for its use. The patch adds a new attribute to the Record class that indicates that this def is actually a class-instance value that may be *used* by other defs in a multiclass. (This is unlike regular defs which don't reference each other and thus can be resolved indepedently.) They are then fully resolved before the other defs while the multiclass is instantiated. I added vg_leak to the new test. I am not sure if this is necessary but I don't think I have a way to test it. I can also check in without the XFAIL and let the bots test this part. Also tested that X86.td.expanded and AAarch64.td.expanded were unchange before and after this change. (This issue triggering this problem is a WIP patch.)

* Change the { } expression in tablegen to accept sized binary literals which ↵Pete Cooper2014-08-071-2/+13
| | | | | | | | | | | | | | | are not just 0 and 1. It also allows nested { } expressions, as now that they are sized, we can merge pull bits from the nested value. In the current behaviour, everything in { } must have been convertible to a single bit. However, now that binary literals are sized, its useful to be able to initialize a range of bits. So, for example, its now possible to do bits<8> x = { 0, 1, { 0b1001 }, 0, 0b0 } llvm-svn: 215086
* Change TableGen so that binary literals such as 0b001 are now sized.Pete Cooper2014-08-071-0/+9
| | | | | | | | | | | | | | | | | Instead of these becoming an integer literal internally, they now become bits<n> values. Prior to this change, 0b001 was 1 bit long. This is confusing as clearly the user gave 3 bits. This new type holds both the literal value and the size, and so can ensure sizes match on initializers. For example, this used to be legal bits<1> x = 0b00; but now it must be written as bits<2> x = 0b00; llvm-svn: 215084

* Introduce a string_ostream string builder faciltyAlp Toker2014-06-261-2/+1
| | | | | | | | | | | | | | | | | | | | 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

* [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 Finkel2014-01-021-1/+1
| | | | | | | | | | | | | | | | 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 Toker2013-12-211-7/+5
