| | | | | | - The world needs better C++ refactoring tools, can I get an Amen!? llvm-svn: 79843

* implement DOTGraphTraits<SelectionDAG*>::getNodeLabel in terms ofChris Lattner2009-06-261-138/+5
| | | | | | SDNode::print_details to eliminate a ton of near-duplicate code. llvm-svn: 74311
* dot graph viewing is apparently not using SDNode::print_details, this is bad,Chris Lattner2009-06-261-0/+7
| | | | | | but in the meantime lets print targetflags on node labels. llvm-svn: 74274
* Get rid of the global CFGOnly flag by threading a ShortNames parameters ↵Owen Anderson2009-06-241-4/+7

* Fix some significant problems with constant pools that resulted in ↵Evan Cheng2009-03-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | unnecessary paddings between constant pool entries, larger than necessary alignments (e.g. 8 byte alignment for .literal4 sections), and potentially other issues. 1. ConstantPoolSDNode alignment field is log2 value of the alignment requirement. This is not consistent with other SDNode variants. 2. MachineConstantPool alignment field is also a log2 value. 3. However, some places are creating ConstantPoolSDNode with alignment value rather than log2 values. This creates entries with artificially large alignments, e.g. 256 for SSE vector values. 4. Constant pool entry offsets are computed when they are created. However, asm printer group them by sections. That means the offsets are no longer valid. However, asm printer uses them to determine size of padding between entries. 5. Asm printer uses expensive data structure multimap to track constant pool entries by sections. 6. Asm printer iterate over SmallPtrSet when it's emitting constant pool entries. This is non-deterministic. Solutions: 1. ConstantPoolSDNode alignment field is changed to keep non-log2 value. 2. MachineConstantPool alignment field is also changed to keep non-log2 value. 3. Functions that create ConstantPool nodes are passing in non-log2 alignments. 4. MachineConstantPoolEntry no longer keeps an offset field. It's replaced with an alignment field. Offsets are not computed when constant pool entries are created. They are computed on the fly in asm printer and JIT. 5. Asm printer uses cheaper data structure to group constant pool entries. 6. Asm printer compute entry offsets after grouping is done. 7. Change JIT code to compute entry offsets on the fly. llvm-svn: 66875
* Oops...I committed too much.Bill Wendling2009-03-131-2/+2

* Temporarily XFAIL this test.Bill Wendling2009-03-131-2/+2

* Pass in a std::string when getting the names of debugging things. This cuts downBill Wendling2009-03-091-1/+2
| | | | | | on the number of times a std::string is created and copied. llvm-svn: 66396
* Move ScheduleDAGSDNodes.h to be a private header. Front-endsDan Gohman2009-02-061-1/+1
| | | | | | | that previously included this header should include SchedulerRegistry.h instead. llvm-svn: 63937

* Experimental post-pass scheduling support. Post-pass schedulingDan Gohman2008-11-191-79/+11
| | | | | | | | | | | | | | | | | is currently off by default, and can be enabled with -disable-post-RA-scheduler=false. This doesn't have a significant impact on most code yet because it doesn't yet do anything to address anti-dependencies and it doesn't attempt to disambiguate memory references. Also, several popular targets don't have pipeline descriptions yet. The majority of the changes here are splitting the SelectionDAG-specific code out of ScheduleDAG, so that ScheduleDAG can be moved to libLLVMCodeGen.a. The interface between ScheduleDAG-using code and the rest of the scheduling code is somewhat rough and will evolve. llvm-svn: 59676
* Move the code for printing a graph node label for an SUnit intoDan Gohman2008-11-191-21/+18

* Check in the correct version of the patch in r59279.Dan Gohman2008-11-141-1/+1

* Debug printing for SUnits that carry MachineInstrs.Dan Gohman2008-11-141-10/+17
| | | | llvm-svn: 59279
* Initial support for carrying MachineInstrs in SUnits.Dan Gohman2008-11-141-4/+17
| | | | llvm-svn: 59278
* Change DOTGraphTraits<ScheduleDAG*>::getGraphName how to find the name ofDan Gohman2008-11-131-1/+1
| | | | | | the current function on its own, rather than relying on the SelectionDAG. llvm-svn: 59277
* Remove the FlaggedNodes member from SUnit. Instead of requiring each SUnitDan Gohman2008-11-131-8/+11
| | | | | | | | | | to carry a SmallVector of flagged nodes, just calculate the flagged nodes dynamically when they are needed. The local-liveness change is due to a trivial scheduling change where the scheduler arbitrary decision differently. llvm-svn: 59273
* Make the Node member of SUnit private, and add accessors.Dan Gohman2008-11-131-2/+2
| | | | llvm-svn: 59264
* Change ScheduleDAG's DAG member from a reference to a pointer, to prepareDan Gohman2008-11-131-4/+4
| | | | | | for the possibility of scheduling without a SelectionDAG being present. llvm-svn: 59263
* Fix bogus comparison of "const char *" with c-string literal. Use strcmp ↵Ted Kremenek2008-10-271-2/+2
| | | | | | instead. llvm-svn: 58290
* Add setSubgraphColor to color an entire portion of a SelectionDAG. ThisDavid Greene2008-10-271-0/+57
| | | | | | will be used to support debug features in TableGen. llvm-svn: 58257
* Don't truncate GlobalAddress offsets to int in debug output.Dan Gohman2008-10-181-1/+1
| | | | llvm-svn: 57770
* don't print GlobalAddressSDNode's with an offset of zero as "foo0".Chris Lattner2008-09-211-5/+6

* Reverting r56249. On further investigation, this functionality isn't needed.Bill Wendling2008-09-161-2/+3
| | | | | | Apologies for the thrashing. llvm-svn: 56251
* Include the alignment value when displaying ConstantPoolSDNodes.Dan Gohman2008-09-161-0/+1
| | | | llvm-svn: 56250
* - Change "ExternalSymbolSDNode" to "SymbolSDNode".Bill Wendling2008-09-161-3/+2
| | | | | | | | | | - Add linkage to SymbolSDNode (default to external). - Change ISD::ExternalSymbol to ISD::Symbol. - Change ISD::TargetExternalSymbol to ISD::TargetSymbol These changes pave the way to allowing SymbolSDNodes with non-external linkage. llvm-svn: 56249
* Define CallSDNode, an SDNode subclass for use with ISD::CALL.Dan Gohman2008-09-131-0/+6
| | | | | | | | | | | | | Currently it just holds the calling convention and flags for isVarArgs and isTailCall. And it has several utility methods, which eliminate magic 5+2*i and similar index computations in several places. CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle nodes that are not CSE'd gracefully. llvm-svn: 56183
* Rename ConstantSDNode::getValue to getZExtValue, for consistencyDan Gohman2008-09-121-1/+1
| | | | | | | with ConstantInt. This led to fixing a bug in TargetLowering.cpp using getValue instead of getAPIntValue. llvm-svn: 56159
* erect abstraction boundaries for accessing SDValue members, rename Val -> ↵Gabor Greif2008-08-281-3/+3

* disallow direct access to SDValue::ResNo, provide a getter insteadGabor Greif2008-08-261-2/+2
| | | | llvm-svn: 55394
* get MachineConstantPool off std::ostream, onto raw_ostream. It would beChris Lattner2008-08-231-10/+17
| | | | | | really nice if someone converted MachineFunction::print to raw_ostream. llvm-svn: 55268
* Move SelectionDAG::viewGraph() out of line; as an inline functionDan Gohman2008-07-301-0/+5
| | | | | | it isn't always visible to gdb. llvm-svn: 54228
* Make the ScheduleDAG's GraphRoot edge be blue and dashed too, likeDan Gohman2008-07-271-1/+2
| | | | | | the SelectionDAG's. llvm-svn: 54129
* Rename SDOperand to SDValue.Dan Gohman2008-07-271-1/+1
| | | | llvm-svn: 54128
* Make the GraphRoot edge look like a chain edge, which is more accurate,Dan Gohman2008-07-221-1/+2
| | | | | | | and use the right result number, in the off chance that the graph root has multiple result values. llvm-svn: 53923
* Enhance the GraphWriter support for edge destinations, and teach theDan Gohman2008-07-211-6/+31
| | | | | | | | SelectionDAG graph writer to make use of them. Now, nodes with multiple values are displayed as such, with incoming edges pointing to the specific value they use. llvm-svn: 53875
* Add titles to the various SelectionDAG viewGraph callsDan Gohman2008-07-211-3/+6
| | | | | | | that include useful information like the name of the block being viewed and the current phase of compilation. llvm-svn: 53872
