* - Two minor improvements to the MachineInstr class to reduce footprint andChris Lattner2002-10-222-13/+12
| | | | | | | overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a bitvector. Sped up LLC a little less than 10% in a debug build! llvm-svn: 4261
* Significant improvement: GEP used by a load or store no longer generatesVikram S. Adve2002-10-141-36/+74
| | | | | | | | | a separate ADD; instead just use the indexed load/store instruction! Also, a bug fix: folding a GEP with a leading non-zero index with its predecessor was incorrect: now it only happens if the predecessor is pointing to an indexable type (aka SequentialType). llvm-svn: 4168
* Use vectors instead of hash_maps for issueGaps and conflictLists.Vikram S. Adve2002-10-131-15/+9
| | | | | | | These hash lookups were a major sink of time because they happen so often! Also, add option to disable scheduling. llvm-svn: 4138
* Major bug fix: was not adding CD edges for RETURNs!Vikram S. Adve2002-10-131-8/+10
| | | | llvm-svn: 4137
* Major bug fix: spill code for an instruction in a delay slot wasVikram S. Adve2002-10-111-11/+73
| | | | | | merrily being inserted before/after the instruction! llvm-svn: 4116
* Don't pad variables in stack slots for performance!Vikram S. Adve2002-10-111-2/+2
| | | | llvm-svn: 4115
* Bug fix in folding getElementPtr instructions: don't fold one intoVikram S. Adve2002-09-291-27/+45
| | | | | | | a predecessor if it has a non-zero first index and the predecessor ends with a struct index. llvm-svn: 3982
* Convert DIRS to PARALLEL_DIRS. They can be built independently.Vikram S. Adve2002-09-291-1/+1
| | | | llvm-svn: 3972
* Added a couple of helper methods for live range construction.Vikram S. Adve2002-09-281-13/+12

* Live ranges for Return value and return address of a Call are nowVikram S. Adve2002-09-281-91/+71
| | | | | | | created here, simply by handling all implicit operands (which should have been done anyway). llvm-svn: 3969
* Fixed method getReturnValue(): it should return NULL if theVikram S. Adve2002-09-281-0/+7

* Fixed incorrect assertion: spill code for function ptr should beVikram S. Adve2002-09-281-3/+4

* Sign-extend integer constants from original type size to 64 bits!Vikram S. Adve2002-09-271-5/+9

* Add method IGNode::getCombinedDegree to count the sum of the degreesVikram S. Adve2002-09-201-0/+3
| | | | | | of two nodes, excluding duplicates. llvm-svn: 3848
* Add PostOpts/ and rename PreSelection/ to PreOpts/.Vikram S. Adve2002-09-201-1/+1
| | | | llvm-svn: 3847
* Add method MachineInstr::replace to rewrite a machine instruction in place.Vikram S. Adve2002-09-201-0/+16
| | | | llvm-svn: 3843
* Allow copy coalescing in more cases: if sum of node degrees is more thanVikram S. Adve2002-09-202-1/+26
| | | | | | | | than #available regs, compute the sum excluding duplicates and if that is less than #regs, go ahead and coalesce. Add method IGNode::getCombinedDegree to count excluding duplicates. llvm-svn: 3842
