2005-10-18Add the ability to lower return instructions to TargetLowering. ThisNate Begeman
allows us to lower legal return types to something else, to meet ABI requirements (such as that i64 be returned in two i32 regs on Darwin/ppc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23802 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-01Annotate nodes with their addresses if a graph requests it.Chris Lattner
This is Jim's feature implemented so that graphs could 'opt-in' and get this behavior. This is currently used by selection dags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23576 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23555 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23535 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-28Add FP versions of the binary operators, keeping the int and fp worlds seperate.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23506 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-27Add a new flag for targets where setjmp/longjmp saves/restores the signal mask,Chris Lattner
and _setjmp/_longjmp should be used instead (for llvm.setjmp/llvm.longjmp). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23479 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-27allow demotion to volatile valuesChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23472 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-27Make this slightly more efficient by pushing actual type information downChris Lattner
into the evaluator. This shrinks a release build of instcombine's text section from 216363 to 215975 bytes (on PPC). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23468 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-27Split SimpleConstantVal up into its components, so each Constant subclass getsChris Lattner
a different enum value. This allows 'classof' for these to be really simple, not needing to call getType() anymore. This speeds up isa/dyncast/etc for constants, and also makes them smaller. For example, the text section of a release build of InstCombine.cpp shrinks from 230037 bytes to 216363 bytes, a 6% reduction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23466 91177308-0d34-0410-b5e6-96231b3b80d8

top bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23200 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-011. Use SubtargetFeatures in llc/lli.Jim Laskey
2. Propagate feature "string" to all targets. 3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23192 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-01This new class provides support for platform specific "features". The intentJim Laskey
is to manage processor specific attributes from the command line. See examples of use in llc/lli and PowerPCTargetSubtarget. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23191 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-01First pass at the DAG Combiner. It isn't used anywhere yet, but it shouldNate Begeman
be mostly functional. It currently has all folds from SelectionDAG.cpp that do not involve a condition code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23184 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-31Add support for count trailing zeroes, and population count. These areNate Begeman
needed for folding constants in the upcoming dag combiner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23163 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-30Allow physregs to occur in the dag with multiple types. Though I don't likeChris Lattner
this, it is a requirement on PPC, which can have an f32 value in r3 at one point in a function and a f64 value in r3 at another point. :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23160 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-30Add AssertSext, AssertZext nodes for targets that pass arguments inNate Begeman
registers, and the incoming values have already been zero or sign extended from the appopriate type to the register width. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23146 91177308-0d34-0410-b5e6-96231b3b80d8
