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

2012-07-05Finish fixing the MachineOperand hashing, providing a nice modernChandler Carruth
hash_value overload for MachineOperands. This addresses a FIXME sufficient for me to remove it, and cleans up the code nicely too. The important changes to the hashing logic: - TargetFlags are now included in all of the hashes. These were complete missed. - Register operands have their subregisters and whether they are a def included in the hash. - We now actually hash all of the operand types. Previously, many operand types were simply *dropped on the floor*. For example: - Floating point immediates - Large integer immediates (>64-bit) - External globals! - Register masks - Metadata operands - It removes the offset from the block-address hash; I'm a bit suspicious of this, but isIdenticalTo doesn't consider the offset for black addresses. Any patterns involving these entities could have triggered extreme slowdowns in MachineCSE or PHIElimination. Let me know if there are PRs you think might be closed now... I'm looking myself, but I may miss them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159743 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-05The hash function for MI expressions, used by MachineCSE, is reallyChandler Carruth
broken. This patch fixes the superficial problems which lead to the intractably slow compile times reported in PR13225. The specific issue is that we were failing to include the *offset* of a global variable in the hash code. Oops. This would in turn cause all MIs which were only distinguishable due to operating on different offsets of a global variable to produce identical hash functions. In some of the test cases attached to the PR I saw hash table activity where there were O(1000) probes-per-lookup *on average*. A very few entries were responsible for most of these probes. There is still quite a bit more to do here. The ad-hoc layering of data in MachineOperands makes them *extremely* brittle to hash correctly. We're missing quite a few other cases, the only ones I've fixed here are the specific MO types which were allowed through the assert() in getOffset(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159741 91177308-0d34-0410-b5e6-96231b3b80d8
