2012-07-27Eliminate the large XXXSubRegTable constant arrays.Jakob Stoklund Olesen
These tables were indexed by [register][subreg index] which made them, very large and sparse. Replace them with lists of sub-register indexes that match the existing lists of sub-registers. MCRI::getSubReg() becomes a very short linear search, like getSubRegIndex() already was. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160843 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-26Remove support for 'CompositeIndices' and sub-register cycles.Jakob Stoklund Olesen
Now that the weird X86 sub_ss and sub_sd sub-register indexes are gone, there is no longer a need for the CompositeIndices construct in .td files. Sub-register index composition can be specified on the SubRegIndex itself using the ComposedOf field. Also enforce unique names for sub-registers in TableGen. The same sub-register cannot be available with multiple sub-register indexes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160842 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-17TableGen: Pattern<> references to null_frag are a nop.Jim Grosbach
A standalone pattern defined in a multiclass expansion should handle null_frag references just like patterns on instructions. Follow-up to r160333. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160384 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-17TableGen: Allow conditional instruction pattern in multiclass.Jim Grosbach
Define a 'null_frag' SDPatternOperator node, which if referenced in an instruction Pattern, results in the pattern being collapsed to be as-if '[]' had been specified instead. This allows supporting a multiclass definition where some instaniations have ISel patterns associated and others do not. For example, multiclass myMulti<RegisterClass rc, SDPatternOperator OpNode = null_frag> { def _x : myI<(outs rc:), (ins rc:), []>; def _r : myI<(outs rc:), (ins rc:), [(set rc:, (OpNode rc:))]>; } defm foo : myMulti<GRa, not>; defm bar : myMulti<GRb>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160333 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-07I'm introducing a new machine model to simultaneously allow simpleAndrew Trick
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

2012-07-02Revert r159528 which taught lit's builtin shell test runner about theChandler Carruth
'|&' bash syntax. We have lots of users with a bash on their system which doesn't support this syntax, and as bash is still significantly faster, we should support them. The test suite has already been updated to cope with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159580 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Make NumMicroOps a variable in the subtarget's instruction itinerary.Andrew Trick
The TargetInstrInfo::getNumMicroOps API does not change, but soon it will be used by MachineScheduler. Now each subtarget can specify the number of micro-ops per itinerary class. For ARM, this is currently always dynamic (-1), because it is used for load/store multiple which depends on the number of register operands. Zero is now a valid number of micro-ops. This can be used for nop pseudo-instructions or instructions that the hardware can squash during dispatch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159406 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26Teach TableGen to put chains on more instructionsTim Northover
When generating selection tables for Pat instances, TableGen relied on an output Instruction's Pattern field being set to infer whether a chain should be added.

2012-06-22TableGen: AsmMatcher support for better operand diagnostics.Jim Grosbach
"Invalid operand" may be a completely correct diagnostic, but it's often insufficiently specific to really help identify and fix the problem in assembly source. Allow a target to specify a more-specific diagnostic kind for each AsmOperandClass derived definition and use that to provide more detailed diagnostics when an operant of that class resulted in a match failure. rdar://8987109 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159050 91177308-0d34-0410-b5e6-96231b3b80d8
