2013-03-24Allow TableGen DAG arguments to be just a name.Jakob Stoklund Olesen
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
2013-03-20Make sure TableGen exits with an error code after printing errors.Jakob Stoklund Olesen
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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177573 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07tblgen: Diagnose duplicate includes.Sean Silva
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174582 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-09Inline this into its only caller.Sean Silva
It's clearer and additionally this gets rid of the usage of `DefmID`, which doesn't really correspond to anything in the language (it was just used in the name of this parsing function which parsed a `MultiClassID` and returned that multiclass's record). This area of the code still needs a lot of work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171938 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
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
2012-10-25Remove exception handling usage from tblgen.Joerg Sonnenberger
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

2012-09-19De-nest if's and fix mix-upSean Silva
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.

2012-09-06Re-work bit/bits value resolving in tblgenMichael Liao
- 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

2012-08-22Print out the location of expanded multiclass defs in TableGen errors.Jakob Stoklund Olesen
When reporting an error for a defm, we would previously only report the location of the outer defm, which is not always where the error is. Now we also print the location of the expanded multiclass defs: lib/Target/X86/X86InstrSSE.td:2902:12: error: foo defm ADD : basic_sse12_fp_binop_s<0x58, "add", fadd, SSE_ALU_ITINS_S>, ^ lib/Target/X86/X86InstrSSE.td:2801:11: note: instantiated from multiclass defm PD : sse12_fp_packed<opc, !strconcat(OpcodeStr, "pd"), OpNode, VR128, ^ lib/Target/X86/X86InstrSSE.td:194:5: note: instantiated from multiclass def rm : PI<opc, MRMSrcMem, (outs RC:$dst), (ins RC:$src1, x86memop:$src2), ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162409 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-02TableGen: Allow use of #NAME# outside of 'def' names.Jim Grosbach
Previously, def NAME values were only populated, and references to NAME resolved, when NAME was referenced in the 'def' entry of the multiclass sub-entry. e.g., multiclass foo<...> { def prefix_#NAME : ... } It's useful, however, to be able to reference NAME even when the default def name is used. For example, when a multiclass has 'def : Pat<...>' or 'def : InstAlias<...>' entries which refer to earlier instruction definitions in the same multiclass. e.g., multiclass myMulti<RegisterClass rc> { def _r : myI<(outs rc:$d), (ins rc:$r), "r $d, $r", []>; def : InstAlias<\"wilma $r\", (!cast<Instruction>(NAME#\"_r\") rc:$r, rc:$r)>; } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161198 91177308-0d34-0410-b5e6-96231b3b80d8
