| | | | llvm-svn: 39732
* Fix an oversight: for modules with no other identifying target info,Chris Lattner2007-07-111-0/+4
| | | | | | the sparc backend should be preferred when running on sparcs. llvm-svn: 39142

* Add FastDSE, a new algorithm for doing dead store elimination. This ↵Owen Anderson2007-07-111-0/+130
| | | | | | | | | | algorithm is not as accurate as the current DSE, but it only a linear scan over each block, rather than quadratic. Eventually (once it has been improved somewhat), this will replace the current DSE. NOTE: This has not yet been extensively tested. llvm-svn: 38517

| | | | llvm-svn: 38504
* Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look forDan Gohman2007-07-101-7/+19
| | | | | | | the new CONCAT_VECTORS node type instead, as that's what legalize uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT. llvm-svn: 38503
* Volatile loads and stores depend on each other.Owen Anderson2007-07-101-0/+17

* Add support for finding the dependencies of call and invoke instructions.Owen Anderson2007-07-101-17/+64
| | | | llvm-svn: 38497
* If the operand is marked M_OPTIONAL_DEF_OPERAND, then it's a def.Evan Cheng2007-07-101-1/+4
| | | | llvm-svn: 38496
* Somehow this wasn't committed last time. M_CLOBBERS_PRED is gone.Evan Cheng2007-07-101-2/+5
| | | | llvm-svn: 38495
* Fix the build, and fix the handling of pointer sizes.Owen Anderson2007-07-101-20/+19

* Fix a bug in the folding of binary operators to undef.Dan Gohman2007-07-101-4/+10
| | | | | | Thanks to Lauro for spotting this! llvm-svn: 38491
* Fix the folding of undef in several binary operators to recognizeDan Gohman2007-07-101-7/+7
| | | | | | undef in either the left or right operand. llvm-svn: 38489
* When a node value is only used by a CopyToReg, use the user's dest. This ↵Evan Cheng2007-07-102-51/+56
| | | | | | should not be restricted to nodes that produce only a single value. llvm-svn: 38485
* Move DenseMapKeyInfo<SDOperand> from LegalizeDAG.cpp to SelectionDAGNodes.hEvan Cheng2007-07-101-12/+0
| | | | llvm-svn: 38484
* Update the ValueRanges interface to use value numbers instead of Value*s.Nick Lewycky2007-07-101-255/+297

* Move some key maps from std::map to DenseMap. This improves the time to ↵Owen Anderson2007-07-101-4/+8
| | | | | | | | optimize Anton's testcase from 17.5s to 15.7s. llvm-svn: 38480
* Use a cheaper test, delaying calling find_leader() until we know that it's ↵Owen Anderson2007-07-101-3/+5
| | | | | | | | necessary. This improves the time to optimize Anton's testcase from 21.1s to 17.6s. llvm-svn: 38479
* Define non-intrinsic instructions for vector min, max, sqrt, rsqrt, and rcp,Dan Gohman2007-07-104-195/+398
| | | | | | | | | in addition to the intrinsic forms. Add spill-folding entries for these new instructions, and for the scalar min and max instrinsic instructions which were missing. And add some preliminary ISelLowering code for using the new non-intrinsic vector sqrt instruction, and fneg and fabs. llvm-svn: 38478
* Add an assertion if find_leader fails.Owen Anderson2007-07-091-0/+1

* Take advantage of the new fast SmallPtrSet assignment operator when ↵Owen Anderson2007-07-091-20/+6
| | | | | | | | propagating AVAIL_OUT sets. This reduces the time to optimize Anton's testcase from 31.2s to 21.s! llvm-svn: 38475
* Make the assignment operator for SmallPtrSet much faster for normal cases.Owen Anderson2007-07-091-36/+21

* Change getCopyToParts and getCopyFromParts to always use target-endianDan Gohman2007-07-092-32/+20
| | | | | | | | register ordering, for both physical and virtual registers. Update the PPC target lowering for calls to expect registers for the call result to already be in target order. llvm-svn: 38471
* Make the assignment operator for SmallPtrSet return a reference, and fix a ↵Owen Anderson2007-07-091-1/+1
| | | | | | | | | | long-standing bug in the copy ctor while I'm at it. Thanks to Chris Lattner for help with this patch. llvm-svn: 38470

| | | | llvm-svn: 38469
* Initialize the IndexedModeActions array with memset beforeDan Gohman2007-07-091-1/+3
| | | | | | | | | | | updating it with calls to setIndexedLoadAction/setIndexedStoreAction, which only update a few bits at a time. This avoids ostensible undefined behavior of operationg on values which may be trap-representations, and as a practical matter fixes errors from valgrind, which doesn't track uninitialized memory with bit granularity. llvm-svn: 38468
