* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-5/+5
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove exception handling usage from tblgen.Joerg Sonnenberger2012-10-251-73/+74
| | | | | | | | | | | | Most places can use PrintFatalError as the unwinding mechanism was not used for anything other than printing the error. The single exception was CodeGenDAGPatterns.cpp, where intermediate errors during type resolution were ignored to simplify incremental platform development. This use is replaced by an error flag in TreePattern and bailout earlier in various places if it is set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166712 91177308-0d34-0410-b5e6-96231b3b80d8
* tblgen: Use semantically correct RTTI functions.Sean Silva2012-10-101-30/+16
| | | | | | Also, some minor cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165647 91177308-0d34-0410-b5e6-96231b3b80d8
* tblgen: Mechanically move dynamic_cast<> to dyn_cast<>.Sean Silva2012-10-101-68/+68
| | | | | | | | | | Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>. That will happen in a future patch. There are also two dyn_cast_or_null<>'s slipped in instead of dyn_cast<>'s, since they were causing crashes with just dyn_cast<>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165646 91177308-0d34-0410-b5e6-96231b3b80d8
* tblgen: Use appropriate LLVM-style RTTI functions.Sean Silva2012-10-051-21/+9
| | | | | | | Use isa<> or cast<> when semantically that is what is happening. Also some trivial "style" cleanups at fix sites. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165292 91177308-0d34-0410-b5e6-96231b3b80d8
* tblgen: Replace uses of dynamic_cast<XXXRecTy> with dyn_cast<>.Sean Silva2012-10-051-20/+20
| | | | | | | | This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of these uses are actually more like isa<> or cast<>, and will be changed to the semanticaly appropriate one in a future patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165291 91177308-0d34-0410-b5e6-96231b3b80d8
* De-nest if's and fix mix-upSean Silva2012-09-191-41/+37
| | | | | | | | | | | | | | | | | | Two deeply nested if's obscured that the sense of the conditions was mixed up. Amazingly, TableGen's output is exactly the same even with the sense of the tests fixed; it seems that all of TableGen's conversions are symmetric so that the inverted sense was nonetheless correct "by accident". As such, I couldn't come up with a test case. If there does in fact exist a non-symmetric conversion in TableGen's type system, then a test case should be prepared. Despite the symmetry, both if's are left in place for robustness in the face of future changes.

* Re-work bit/bits value resolving in tblgenMichael Liao2012-09-061-114/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

| | | | | | | Keep track of the set/unset state of these bits along with their true/false values, but treat '?' as '0' for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162461 91177308-0d34-0410-b5e6-96231b3b80d8
* TableGen: Location information for diagnostic.Jim Grosbach2012-07-121-1/+1
| | | | | | | | | | | def Pat<...>; Results in 'record name is not a string!' diagnostic. Not the best, but the lack of location information moves it from not very helpful into completely useless. We're in the Record class when throwing the error, so just add the location info directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160098 91177308-0d34-0410-b5e6-96231b3b80d8

* Delete CodeInit and CodeRecTy from TableGen.Jakob Stoklund Olesen2012-01-131-30/+0
| | | | | | | The code type was always identical to a string anyway. Now it is simply a synonym. The code literal syntax [{...}] is still valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148092 91177308-0d34-0410-b5e6-96231b3b80d8

* 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144422 91177308-0d34-0410-b5e6-96231b3b80d8
* Add NAME MemberDavid Greene2011-10-191-0/+5
| | | | | | | | 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

| | | | | | | 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

* Make Template Arg Names InitsDavid Greene2011-10-191-3/+6
| | | | | | | | 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
* Add Utility to Scope NamesDavid Greene2011-10-191-0/+36
| | | | | | | | Add a couple of utility functions to take a variable name and qualify it with the namespace of the enclosing class and/or multiclass.

* Make VarInit Name an InitDavid Greene2011-10-191-1/+13
| | | | | | | | 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 Greene2011-10-191-0/+12
| | | | | | | | 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
* Fix List-of-List ProcessingDavid Greene2011-10-061-1/+3
| | | | | | | | | Fix VarListElementInit::resolveListElementReference to return a partially resolved VarListElementInint in the case where full resolution is not possible. This allows TableGen to make forward progress resolving certain complex list expressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141315 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow Operator ArgumentsDavid Greene2011-10-041-5/+13
| | | | | | | | | | | | | | | When resolving an operator list element reference, resolve all operator operands and try to fold the operator first. This allows the operator to collapse to a list which may then be indexed. Before, it was not possible to do this: class D<int a, int b> { ... } class C<list<int> A> : D<A[0], A[1]>; class B<list<int> b> : C<!foreach(...,b)>; Now it is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141101 91177308-0d34-0410-b5e6-96231b3b80d8
