* I accidentally removed this check in an earlier commit, which cause breakage ↵Owen Anderson2009-01-211-0/+4
| | | | | | in the pre alloc splitter. llvm-svn: 62678
* Implement LowerOperationWrapper for legalizer. Sanjiv Gupta2009-01-215-138/+174
| | | | | | Also a few signed comparison fixes. llvm-svn: 62665
* CellSPU:Scott Michel2009-01-219-130/+317
| | | | | | | | | | | | | - Ensure that (operation) legalization emits proper FDIV libcall when needed. - Fix various bugs encountered during llvm-spu-gcc build, along with various cleanups. - Start supporting double precision comparisons for remaining libgcc2 build. Discovered interesting DAGCombiner feature, which is currently solved via custom lowering (64-bit constants are not legal on CellSPU, but DAGCombiner insists on inserting one anyway.) - Update README. llvm-svn: 62664
* Allow targets to legalize operations (with illegal operands) that produces ↵Sanjiv Gupta2009-01-215-68/+85
| | | | | | multiple values. For example, a load with an illegal operand (a load produces two values, a value and chain). llvm-svn: 62663
* Favors generating "not" over "xor -1". For example.Evan Cheng2009-01-211-0/+3
| | | | | | | | | | | | | | | | | unsigned test(unsigned a) { return ~a; } llvm used to generate: movl $4294967295, %eax xorl 4(%esp), %eax Now it generates: movl 4(%esp), %eax notl %eax It's 3 bytes shorter. llvm-svn: 62661
* Make special cases (0 inf nan) work for frem.Dale Johannesen2009-01-213-38/+68
| | | | | | | | Besides APFloat, this involved removing code from two places that thought they knew the result of frem(0., x) but were wrong. llvm-svn: 62645
* Be more aggressive about renumbering vregs after splitting them.Owen Anderson2009-01-211-3/+7

* Fix PR3243: a LiveVariables bug. When HandlePhysRegKill is checking whether ↵Evan Cheng2009-01-201-13/+15
| | | | | | the last reference is also the last def (i.e. dead def), it should also check if last reference is the current machine instruction being processed. This can happen when it is processing a physical register use and setting the current machine instruction as sub-register's last ref. llvm-svn: 62617
* Fix typo. Patch by Alexei Svitkine.Duncan Sands2009-01-201-1/+1
| | | | llvm-svn: 62616
* Use "SINT_TO_FP" instead of "UINT_TO_FP" when getting the exponent. This wasBill Wendling2009-01-201-12/+13
| | | | | | | causing the limited precision stuff to produce the wrong result for values in the range [0, 1). llvm-svn: 62615
* Fix struct member's debug info.Devang Patel2009-01-201-7/+24
| | | | llvm-svn: 62610
* Need only one set of debug info versions enum.Devang Patel2009-01-202-6/+6
| | | | llvm-svn: 62602
* Change TargetInstrInfo::isMoveInstr to return source and destination ↵Evan Cheng2009-01-2031-123/+157
| | | | | | sub-register indices as well. llvm-svn: 62600
* Fix global variable's address in a DIE.Devang Patel2009-01-201-1/+1
| | | | llvm-svn: 62596
* Enable debug info for enums.Devang Patel2009-01-201-10/+14
| | | | llvm-svn: 62594
* Add an IEEE remainder function, which is notDale Johannesen2009-01-201-1/+39
| | | | | | | | fully implemented yet and not used. This is mainly to clarify that APFloat::mod implements C fmod, not remainder. llvm-svn: 62593

* Fix a dagcombine to not generate loads of non-round integer types,Dan Gohman2009-01-201-1/+1

* Make the Interpreter use libffi if it's available. Patch from Alexei Svitkine!Nick Lewycky2009-01-201-496/+206
| | | | | | | | | | | This requires a rebuild of 'configure' itself. I will be committing that next, but built with the wrong version of autoconf. Somebody who has the right one, please update it. As a side-note, because of the way autoconf works, all built tools will link against libffi, not just lli. If you know how to fix this, please let me know ... llvm-svn: 62553

* Remove SDNode's virtual destructor. This makes it impossible forDan Gohman2009-01-191-53/+14
| | | | | | | | | | | | | | SDNode subclasses to keep state that requires non-trivial destructors, however it was already effectively impossible, since the destructor isn't actually ever called. There currently aren't any SDNode subclasses affected by this, and in general it's desireable to keep SDNode objects light-weight. This eliminates the last virtual member function in the SDNode class, so it eliminates the need for a vtable pointer, making SDNode smaller. llvm-svn: 62539

* div/rem by zero and div/rem overflow are both undefined according toChris Lattner2009-01-191-11/+11

* Fix SelectionDAG::ReplaceAllUsesWith to behave correctly whenDan Gohman2009-01-192-16/+39
| | | | | | | | | | | | | uses are added to the From node while it is processing From's use list, because of automatic local CSE. The fix is to avoid visiting any new uses. Fix a few places in the DAGCombiner that assumed that after a RAUW call, the From node has no users and may be deleted. This fixes PR3018. llvm-svn: 62533
