* Eliminate MachineBasicBlock::const_livein_iterator and makeDan Gohman2010-04-131-1/+1
| | | | | | | | | MachineBasicBlock::livein_iterator a const_iterator, because clients shouldn't ever be using the iterator interface to mutate the livein set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101147 91177308-0d34-0410-b5e6-96231b3b80d8

* move target-independent opcodes out of TargetInstrInfoChris Lattner2010-02-091-6/+4

* Remove livein checks from machine code verifier.Jakob Stoklund Olesen2010-01-051-99/+13
| | | | | | | | | | | A phi operand that is implicitly defined in a predecessor becomes an undefined register after phi elimination. This causes a lot of false positives when the verifier is checking if live-in registers are live-out from all predecessors. Removing the verifier checks seems like a better solution than insisting on IMPLICIT_DEF instructions in predecessor blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92769 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove minimal CFG sanity checks from verifier.Jakob Stoklund Olesen2009-12-221-18/+0
| | | | | | | | | These checks would often trigger on unreachable statements inserted by bugpoint, leading it astray. It would be nice if we could distinguish unreachable blocks from errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91923 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor ofDan Gohman2009-12-051-9/+0
| | | | | | | | MachineBasicBlock::canFallThrough(), which is target-independent and more thorough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90634 91177308-0d34-0410-b5e6-96231b3b80d8
* Add MachineBasicBlock::getName, and use it in place of getBasicBlock()->getName.Jakob Stoklund Olesen2009-11-201-1/+1

* Fix verification of explicit operands.Jakob Stoklund Olesen2009-09-231-8/+11
| | | | | | | | | | The machine code verifier did not check for explicit operands correctly. It used MachineInstr::getNumExplicitOperands, but that method may cheat and use the declared count in the TargetInstrDesc. Now we check the explicit operands one at a time in visitMachineOperand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82652 91177308-0d34-0410-b5e6-96231b3b80d8
* Verify that phi instructions refer to MBBs in the CFG.Jakob Stoklund Olesen2009-09-211-7/+8
| | | | | | | The machine code verifier no longer tolerates phi instructions with noop operands. All MBBs on a phi instruction must be in the CFG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82448 91177308-0d34-0410-b5e6-96231b3b80d8

* remove various std::ostream version of printing methods fromChris Lattner2009-08-231-1/+1
| | | | | | | | | MachineInstr and MachineOperand. This required eliminating a bunch of stuff that was using DOUT, I hope that bill doesn't mind me stealing his fun. ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79813 91177308-0d34-0410-b5e6-96231b3b80d8
* remove std::ostream versions of printing stuff for MBB and MF,Chris Lattner2009-08-231-3/+3
| | | | | | | upgrading a few things to use raw_ostream git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79811 91177308-0d34-0410-b5e6-96231b3b80d8
* Change raw_fd_ostream to take flags as an optional bitmask Chris Lattner2009-08-231-22/+19
| | | | | | | | | | | | | | | | | | | instead of as two bools. Use this to add a F_Append flag which has the obvious behavior. Other unrelated changes conflated into this patch: 1. REmove EH stuff from llvm-dis and llvm-as, the try blocks are dead. 2. Simplify the filename inference code in llvm-as/llvm-dis, because raw_fd_ostream does the right thing with '-'. 3. Switch machine verifier to use raw_ostream instead of ostream (Which is the thing that needed append in the first place). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79807 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean out per-function data after the machine code verifier is done with it.Jakob Stoklund Olesen2009-08-081-0/+8
| | | | | | | | | | | | | | | Also don't dereference old pointers after they have been deleted causing random crashes when enabling the machine code verifier. Ahem... I have not included a test case for the crash. It hapened when enabling the verifier on CodeGen/X86/2009-08-06-branchfolder-crash.ll. The crash depends on an MBB being allocated at the same address as a previously deleted MBB. I don't think that can be reproduced reliably. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78472 91177308-0d34-0410-b5e6-96231b3b80d8

* Enforce stricter rules in machine code verifier.Jakob Stoklund Olesen2009-08-041-20/+15
| | | | | | | | | | | Implicit operands no longer get a free pass: Imp-use requires a live register and imp-def requires a dead register. There is also no special rule allowing redefinition of a sub-register when the super-register is live. The super register must have imp-kill+imp-def operands instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78090 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle <undef> flag in machine code verifier.Jakob Stoklund Olesen2009-08-021-1/+2
| | | | | | Use of an <undef> register is treated like an <imp-use>. It is not an error to use a dead <undef> register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77890 91177308-0d34-0410-b5e6-96231b3b80d8

Make PointerLikeRegClass contain a 'kind' int, and store it in the existing regclass field of TargetOperandInfo when the isLookupPtrRegClass() predicate is set. Make getRegClass pass this into TargetRegisterInfo::getPointerRegClass(), allowing targets to have multiple ptr_rc things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77504 91177308-0d34-0410-b5e6-96231b3b80d8
* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-251-2/+2
| | | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

The machine code verifier is enabled with the command-line option '-verify-machineinstrs', or by defining the environment variable LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the verifier errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71918 91177308-0d34-0410-b5e6-96231b3b80d8
