| | | | | | | I've tried to find main moudle headers where possible, but the TableGen stuff may warrant someone else looking at it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169251 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove exception handling usage from tblgen.Joerg Sonnenberger2012-10-251-14/+15
| | | | | | | | | | | | 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

* Add a new optimization pass: Stack Coloring, that merges disjoint static ↵Nadav Rotem2012-09-061-0/+2
| | | | | | | | | | allocations (allocas). Allocas are known to be disjoint if they are marked by disjoint lifetime markers (@llvm.lifetime.XXX intrinsics). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163299 91177308-0d34-0410-b5e6-96231b3b80d8
* Add CodeGenTarget::guessInstructionProperties.Jakob Stoklund Olesen2012-08-231-0/+9
| | | | | | | | | | | | Currently, TableGen just guesses instruction properties when it can't infer them form patterns. This adds a guessInstructionProperties flag to the instruction set definition that will be used to disable guessing. The flag is intended as a migration aid. It will be removed again when no more targets need their properties guessed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162460 91177308-0d34-0410-b5e6-96231b3b80d8
* I'm introducing a new machine model to simultaneously allow simpleAndrew Trick2012-07-071-1/+11
| | | | | | | | | | | | | | | | | | | | | | | subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159891 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "Emit the SubRegTable with the smallest possible integer type."Jim Grosbach2012-03-011-8/+0
| | | | | | | | | | This reverts commit 151760. We want to move getSubReg() from TargetRegisterInfo into MCRegisterInfo, but to do that, the type of the lookup table needs to be the same for all targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151814 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Make Inits FoldableDavid Greene2011-07-111-2/+2
| | | | | | | | | | | | | | | | | | Manage Inits in a FoldingSet. This provides several benefits: - Memory for Inits is properly managed - Duplicate Inits are folded into Flyweights, saving memory - It enforces const-correctness, protecting against certain classes of bugs The above benefits allow Inits to be used in more contexts, which in turn provides more dynamism to TableGen. This enhanced capability will be used by the AVX code generator to a fold common patterns together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134907 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | features like register pairs and lists with "interesting" constraints (such as ARM NEON contiguous register lists or even-odd paired registers). We need to be able to generate these instructions (often from intrinsics), but don't want to have to assign a legal type to them. Instead, we'll use an "untyped" edge to bypass the type-checking and simply ensure that the register classes match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133106 91177308-0d34-0410-b5e6-96231b3b80d8
* Give CodeGenRegisterClass a real sorted member set.Jakob Stoklund Olesen2011-06-151-5/+4
| | | | | | | | | | | Make the Elements vector private and expose an ArrayRef through getOrder() instead. getOrder will eventually provide multiple user-specified allocation orders. Use the sorted member set for member and subclass tests. Clean up a lot of ad hoc searches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133040 91177308-0d34-0410-b5e6-96231b3b80d8

* Move TableGen's register bank classes to their own source file.Jakob Stoklund Olesen2011-06-091-73/+0
| | | | | | | | | | | I'll be moving some more code there to gather all of the register-specific stuff in one place. Currently it is shared between CodeGenTarget and RegisterInfoEmitter. The plan is that CodeGenRegisters can compute the full register bank structure while RegisterInfoEmitter only will handle the printing part. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132788 91177308-0d34-0410-b5e6-96231b3b80d8
* Make it possible to have unallocatable register classes.Jakob Stoklund Olesen2011-06-021-0/+1
| | | | | | | | | | | | | | | Some register classes are only used for instruction operand constraints. They should never be used for virtual registers. Previously, those register classes were given an empty allocation order, but now you can say 'let isAllocatable=0' in the register class definition. TableGen calculates if a register is part of any allocatable register class, and makes that information available in TargetRegisterDesc::inAllocatableClass. The goal here is to eliminate use cases for overriding allocation_order_* methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132508 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't allow per-register spill size and alignment.Jakob Stoklund Olesen2011-04-211-2/+0
| | | | | | | These values were not used for anything. Spill size and alignment is a property of the register class, not the register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129906 91177308-0d34-0410-b5e6-96231b3b80d8
* Prefer cheap registers for busy live ranges.Jakob Stoklund Olesen2011-04-201-0/+1
| | | | | | | | | | | | | | On the x86-64 and thumb2 targets, some registers are more expensive to encode than others in the same register class. Add a CostPerUse field to the TableGen register description, and make it available from TRI->getCostPerUse. This represents the cost of a REX prefix or a 32-bit instruction encoding required by choosing a high register. Teach the greedy register allocator to prefer cheap registers for busy live ranges (as indicated by spill weight). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129864 91177308-0d34-0410-b5e6-96231b3b80d8
