* Add support for running SelectionDAG if FastISel fails. This is underDan Gohman2008-08-201-11/+16
| | | | | | | a command-line option, so that the default behavior is an abort, which is useful for exposing code that isn't supported yet. llvm-svn: 55028
* Fix FastISel to recognize unhandled operands, such as constantsDan Gohman2008-08-201-0/+4
| | | | | | that aren't available as virtual registers (for now). llvm-svn: 55026

| | | | llvm-svn: 55015
* Support unconditional fall-through branches in FastISel.Dan Gohman2008-08-191-0/+16

* Allow the fast-path spilling code to attempt folding, but still leaving out ↵Owen Anderson2008-08-191-59/+68
| | | | | | remat and splitting. llvm-svn: 55012
* Use the BuildMI overload that sets up a destination registerDan Gohman2008-08-191-6/+3
| | | | | | instead of the one that doesn't and then adding it manually. llvm-svn: 55006
* Handle the case where target-specific fastisel code doesn't haveDan Gohman2008-08-191-0/+5

* The fast-path still needs to set kill markers and spill/restore points as ↵Owen Anderson2008-08-191-0/+3
| | | | | | | | | appropriate. With this patch, all of MultiSource/Applications and all of SPEC2000/2006 pass with the SimpleSpiller and this fast-path enabled. llvm-svn: 55000

| | | | llvm-svn: 54968
* Add a flag to enable the fast spilling path.Owen Anderson2008-08-191-0/+7
| | | | llvm-svn: 54958
* Fix a few more bugs:Owen Anderson2008-08-181-3/+8
| | | | | | | 1) Assign stack slots to new temporaries. 2) Don't insert an interval into the return vector more than once. llvm-svn: 54956
* Fix several bugs in the new fast-path:Owen Anderson2008-08-181-16/+16
| | | | | | | | 1) Remove an incorrect assertion. 2) Set the stack slot weight properly. 3) Resize the VirtRegMap when needed. llvm-svn: 54949
* Clients of addIntervalForSpills expect the added intervals to be returned ↵Owen Anderson2008-08-181-0/+9
| | | | | | sorted by starting index. llvm-svn: 54939
* Simplify the fast-patch interval spilling by using ↵Owen Anderson2008-08-181-72/+50
| | | | | | MachineRegisterInfo::reg_iterator. llvm-svn: 54930
* Resurrect some ancient code to add spill ranges without attempting folding, ↵Owen Anderson2008-08-181-0/+105
| | | | | | | | | remat, or splitting. This code has been updated to current APIs in so far as it compiles and, in theory, works, but does not take advantage of recent advancements. For instance, it could be improved by using MachineRegisterInfo::use_iterator. llvm-svn: 54924
* Don't hoist instructions that have implicit uses or defines. Before, it wasBill Wendling2008-08-181-0/+5
| | | | | | hoisting out some "test" and "cmp" instructions. This was obvious badness. llvm-svn: 54908
* Don't require Registry specializations to define random static variables.Gordon Henriksen2008-08-172-18/+0
| | | | llvm-svn: 54902
* Drop an unnecessary include.Gordon Henriksen2008-08-171-1/+0
| | | | llvm-svn: 54901
* Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen2008-08-1710-254/+226
| | | | | | | | | | | | | | | | | | In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. llvm-svn: 54899
* Don't instantiate GC metadata for declarations.Gordon Henriksen2008-08-172-1/+3

* Fix merge errorAnton Korobeynikov2008-08-173-175/+0

* Factor out asmprinters from collector interface.Anton Korobeynikov2008-08-171-0/+18

* Factor GC metadata table assembly generation out of Collector in preparation ↵Gordon Henriksen2008-08-1710-50/+94

* Factor GC metadata table assembly generation out of Collector in preparation ↵Gordon Henriksen2008-08-174-18/+72
| | | | | | for splitting AsmPrinter into its own library. llvm-svn: 54880
* Rework the routines that convert AP[S]Int into a string. Now, instead ofChris Lattner2008-08-172-7/+10
| | | | | | | | | | | | | | | | | returning an std::string by value, it fills in a SmallString/SmallVector passed in. This significantly reduces string thrashing in some cases. More specifically, this: - Adds an operator<< and a print method for APInt that allows you to directly send them to an ostream. - Reimplements APInt::toString to be much simpler and more efficient algorithmically in addition to not thrashing strings quite as much. This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the asmprinter. This also fixes a bug I introduced into the asmwriter in a previous patch w.r.t. alias printing. llvm-svn: 54873
* Move SLEB/ULEB size calculation routines from AsmPrinter to TargetAsmInfo. ↵Anton Korobeynikov2008-08-162-428/+402
| | | | | | This makes JIT asmprinter-free. llvm-svn: 54843
* Convert several std::vectors over to SmallVector, and use reserve() as ↵Owen Anderson2008-08-151-2/+4
| | | | | | appropriate for cases where std::vector is still used. llvm-svn: 54820
* Use SmallSet instead of std::set to save allocations.Owen Anderson2008-08-141-3/+3
| | | | llvm-svn: 54810
* Move MachineInstr::getOpcode inline.Owen Anderson2008-08-141-6/+0
| | | | llvm-svn: 54807
* Convert uses of std::vector in TargetInstrInfo to SmallVector. This change ↵Owen Anderson2008-08-144-35/+37
| | | | | | had to be propoagated down into all the targets and up into all clients of this API. llvm-svn: 54802
* Make FastISel's constructor protected, and give it a destructor.Dan Gohman2008-08-141-0/+2
| | | | llvm-svn: 54793
* Remove more uses of std::set.Owen Anderson2008-08-141-6/+8

* Improve support for vector casts in LLVM IR and CodeGen.Dan Gohman2008-08-144-88/+221
| | | | llvm-svn: 54784
* Speed up addRegisterDead by adding more fast checks before performing the ↵Owen Anderson2008-08-141-1/+3
| | | | | | | | | expensive subregister query, and by increasing the size of the subregister hashtable so that there are fewer collisions. llvm-svn: 54781
* Use empty() instead of begin() == end().Dan Gohman2008-08-144-5/+5
| | | | llvm-svn: 54780

* Fix a bogus srem rule - a negative value srem'd by a power-of-2Dan Gohman2008-08-131-5/+3
| | | | | | | can have a non-negative result; for example, -16%16 is 0. Also, clarify the related comments. This fixes PR2670. llvm-svn: 54767

* Allow SelectionDAG to create EXTRACT_VECTOR_ELT nodes withDan Gohman2008-08-131-11/+9
| | | | | | | non-constant indices. Only a few of the peephole checks require a constant index. llvm-svn: 54764
