* Silence a bogus compiler warning.Evan Cheng2009-01-261-1/+1
| | | | llvm-svn: 63021
* Actually source file has already been uniquified into an id during isel. ↵Evan Cheng2009-01-261-15/+3
| | | | | | Eliminate the StringMap. llvm-svn: 63009
* Add data structure to define and track debug location during codegen.Evan Cheng2009-01-261-0/+27
| | | | llvm-svn: 63008
* Fixed optimization of combining two shuffles where the first shuffle inputsMon P Wang2009-01-261-1/+3
| | | | | | has a different number of elements than the output. llvm-svn: 62998
* Take the next steps in making SDUse more consistent with LLVM Use, andDan Gohman2009-01-264-88/+77
| | | | | | | | | | | | | | | | | tidy up SDUse and related code. - Replace the operator= member functions with a set method, like LLVM Use has, and variants setInitial and setNode, which take care up updating use lists, like LLVM Use's does. This simplifies code that calls these functions. - getSDValue() is renamed to get(), as in LLVM Use, though most places can either use the implicit conversion to SDValue or the convenience functions instead. - Fix some more node vs. value terminology issues. Also, eliminate the one remaining use of SDOperandPtr, and SDOperandPtr itself. llvm-svn: 62995
* Untabify code.Scott Michel2009-01-266-49/+49
| | | | llvm-svn: 62991
* CellSPU:Scott Michel2009-01-266-231/+468
| | | | | | | | | | | | | | | | - Rename fcmp.ll test to fcmp32.ll, start adding new double tests to fcmp64.ll - Fix select_bits.ll test - Capitulate to the DAGCombiner and move i64 constant loads to instruction selection (SPUISelDAGtoDAG.cpp). <rant>DAGCombiner will insert all kinds of 64-bit optimizations after operation legalization occurs and now we have to do most of the work that instruction selection should be doing twice (once to determine if v2i64 build_vector can be handled by SelectCode(), which then runs all of the predicates a second time to select the necessary instructions.) But, CellSPU is a good citizen.</rant> llvm-svn: 62990

* Handle single-entry phi nodes gracefully in condprop.Chris Lattner2009-01-261-0/+8
| | | | llvm-svn: 62985
* Fix PR3408 by making a non-obvious assumption very obvious, and Chris Lattner2009-01-261-2/+6
| | | | | | handling the flaw inherent in that assumption. :) llvm-svn: 62984
* More cleanups and simplifications, no functionality change.Chris Lattner2009-01-261-47/+23
| | | | llvm-svn: 62983
* tidy assertsChris Lattner2009-01-261-18/+17

* Map address space 256 to gs; similar mappings could be supported for theNate Begeman2009-01-262-0/+20
| | | | | | | other x86 segments. address space 0 is stack/default, 1-255 are reserved for client use. llvm-svn: 62980
* Support pattern matching various x86 sse shifts.Nate Begeman2009-01-261-0/+93
| | | | llvm-svn: 62979
* silence a warning when assertions are disabled.Chris Lattner2009-01-251-3/+3
| | | | llvm-svn: 62976
* should have removed the + when manually applying a patch!Torok Edwin2009-01-251-2/+2
| | | | llvm-svn: 62973
* revert this patch for now, because Codegen does still want to generate SSE code,Torok Edwin2009-01-251-0/+4
| | | | | | for example in the case of va-args. XFAIL associated tests. llvm-svn: 62972
* If user explicitly asks not to use SSE, don't force it. This fixes LLVM part ↵Torok Edwin2009-01-251-2/+0
| | | | | | of PR3402. llvm-svn: 62967
* Eliminate the loop that searches through each of the operandsDan Gohman2009-01-251-195/+178
| | | | | | | | | | | of each use in the SelectionDAG ReplaceAllUses* functions. Thanks to Chris for spotting this opportunity. Also, factor out code from all 5 of the ReplaceAllUses* functions into AddNonLeafNodeToCSEMaps, which is now renamed AddModifiedNodeToCSEMaps to more accurately reflect its purpose. llvm-svn: 62964
* Whitespace tidiments.Dan Gohman2009-01-251-2/+1
| | | | llvm-svn: 62963
* Move the N->use_empty() assert from DeleteNode toDan Gohman2009-01-251-3/+2
| | | | | | | DeleteNodeNotInCSEMaps, since DeleteNode just calls DeleteNodeNotInCSEMaps. llvm-svn: 62962
* Start generating arbitrary precision integer SCEVs. This removes the temporaryNick Lewycky2009-01-251-11/+1
| | | | | | code that rounded up and capped the size. llvm-svn: 62958

* Teach 2addr pass to be do more commuting. If both uses of a two-address ↵Evan Cheng2009-01-251-6/+104
| | | | | | | | | | | | | | | | | | | | | instruction are killed, but the first operand has a use before and after the def, commute if the second operand does not suffer from the same issue. %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1028 %reg1030<def> = ADD8rr %reg1028<kill>, %reg1029<kill>, %EFLAGS<imp-def,dead> In this case, it might not be possible to coalesce the second MOV8rr instruction if the first one is coalesced. So it would be profitable to commute it: %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1029 %reg1030<def> = ADD8rr %reg1029<kill>, %reg1028<kill>, %EFLAGS<imp-def,dead> llvm-svn: 62954
* Fix an indent and a typo.Nate Begeman2009-01-242-2/+2
| | | | llvm-svn: 62940
* Revert previous change; even this mild and clearlyDale Johannesen2009-01-241-7/+4
| | | | | | | more accurate change loses more than it gains on benchmarks. llvm-svn: 62938
* add note about possible GEP improvement with fields of size 0.Torok Edwin2009-01-241-0/+6
| | | | llvm-svn: 62925
* testcase for PR3381.Torok Edwin2009-01-241-1/+1
| | | | | | Also it was an empty struct, not a void after all. llvm-svn: 62920
* void* is represented as pointer to empty struct {}.Torok Edwin2009-01-241-0/+2
| | | | | | | Thus we need to check whether the struct is empty before trying to index into it. This fixes PR3381. llvm-svn: 62918
* Some cleanups. No functional changes.Owen Anderson2009-01-241-26/+34
| | | | llvm-svn: 62917
* Improve the inlining cost function a bit.Dale Johannesen2009-01-241-3/+6
| | | | | | Little practical effect. llvm-svn: 62908
* Make InstCombineStoreToCast handle aggregates more aggressively,Chris Lattner2009-01-241-18/+48
| | | | | | | handling the case in Transforms/InstCombine/cast-store-gep.ll, which is a heavily reduced testcase from Clang on x86-64. llvm-svn: 62904
* Refactor code. No functionality change.Evan Cheng2009-01-231-20/+38
| | | | llvm-svn: 62893
* Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel2009-01-233-2/+13
| | | | | | | | | | | | DW_AT_APPLE_flags. DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by a project, irrespective of whether the project used makefile, Xcode or something else. llvm-gcc patch is next. llvm-svn: 62888
* hopefully address PR3379 by making the P modifier work in x86 inline asm.Chris Lattner2009-01-231-0/+3

* use CallSite::isCalle instead of slow getOperandNoGabor Greif2009-01-231-3/+3
| | | | llvm-svn: 62877
* Simplify the logic of getting hold of a PHI predecessor block.Gabor Greif2009-01-234-10/+5
| | | | | | | | | There is now a direct way from value-use-iterator to incoming block in PHINode's API. This way we avoid the iterator->index->iterator trip, and especially the costly getOperandNo() invocation. Additionally there is now an assertion that the iterator really refers to one of the PHI's Uses. llvm-svn: 62869
* Add support for deleting a module provider from a JIT in such a way that it ↵Nate Begeman2009-01-233-1/+41
| | | | | | does not cause the owned module to be fully materialized. llvm-svn: 62864
* Empty DIType represents void. In this case no need to construct any type DIE.Devang Patel2009-01-231-3/+1
| | | | llvm-svn: 62861
* Fold x-0 to x in unsafe-fp-math mode. This comes up in theDan Gohman2009-01-232-9/+19
| | | | | | | | | | | | | | testcase from PR3376, and in fact is sufficient to completely avoid the problem in that testcase. There's an underlying problem though; TLI.isOperationLegal considers Custom to be Legal, which might be ok in some cases, but that's what DAGCombiner is using in many places to test if something is legal when LegalOperations is true. When DAGCombiner is running after legalize, this isn't sufficient. I'll address this in a separate commit. llvm-svn: 62860
* fix two more cases where we could let the NLPDI cache get unsorted.Chris Lattner2009-01-231-5/+14
| | | | | | With this, sqlite3 now passes. llvm-svn: 62839
* Unconditionally reset 'cache' to zero, even if we don't need to resort it.Chris Lattner2009-01-231-5/+4
| | | | | | | | | This avoids using a dangling pointer. Reset NumSortedEntries after restoring Cache to avoid extraneous sorts. This fixes the reduced sqlite3 testcase, but apparently not the whole app. llvm-svn: 62838
* Only check if coalescing is worthwhile when the result is targeting a more ↵Evan Cheng2009-01-231-1/+6
| | | | | | restrictive register class. llvm-svn: 62837
* Stage two of fixing pre-alloc-splitting's code size issues: filter out ↵Owen Anderson2009-01-231-9/+37
| | | | | | | | | | restores that are just going to be re-spilled again. This also helps performance. Pre-alloc-splitting now seems to be an overall win on SPEC. llvm-svn: 62834
* Cross register class coalescing. Not yet enabled.Evan Cheng2009-01-232-109/+123
| | | | llvm-svn: 62832
* Code did not follow associated comment. not a good idea.Devang Patel2009-01-231-1/+1
| | | | llvm-svn: 62828
* Set appropriate tag for the composite type.Devang Patel2009-01-231-0/+1
| | | | llvm-svn: 62827
* a minor tweak to my previous patch, handle the invalidation caseChris Lattner2009-01-231-3/+4
