2009-07-10Generalize ScalarEvolution's cast-folding code to support more kindsDan Gohman

2009-07-10Add Thumb2ITBlockPass.cpp to CMakeLists.txt, fixingDuncan Sands
the cmake build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75246 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10make this more like printOperand. Perhaps some merging will happenChris Lattner
tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75245 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10simplify fast isel by using ClassifyGlobalReference. ThisChris Lattner
elimiantes the last use of GVRequiresExtraLoad, so delete it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75244 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10eliminate GVRequiresRegister, replacing it with predicates we Chris Lattner
need for other purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75243 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10change a bunch of logic in LowerGlobalAddress to leverage the workChris Lattner
done in ClassifyGlobalReference instead of reconstructing the info awkwardly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75240 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10add a predicate to determine if a global var reference requires aChris Lattner
PIC-base to be added in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75238 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10move some classification logic around. Now GVRequiresExtraLoadChris Lattner
is just a trivial wrapper around "ClassifyGlobalReference", which stole a ton of logic from LowerGlobalAddress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75237 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10change isGlobalStubReference to take target flags instead of a MachineOperand.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75236 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10convert some late code (called by regalloc and code emission)Chris Lattner
to use isGlobalStubReference instead of GVRequiresExtraLoad (which should really be part of isel). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75234 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10add a new predicate method that says whether a GlobalValue Chris Lattner
MachineOperand is a reference to a stub, not a reference to the global variable itself. Look no context needed! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75233 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10GVRequiresExtraLoad is now never used for calls, simplify it based on this.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75232 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10actually, just eliminate PCRelGVRequiresExtraLoad. It makes the codeChris Lattner
more complex and slow than just directly testing what we care about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75231 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10There is only one case where GVRequiresExtraLoad returns true for calls:Chris Lattner
split its handling out to PCRelGVRequiresExtraLoad, and simplify code based on this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75230 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10the "isDirectCall" operand of GVRequiresRegister is always false, eliminate it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75229 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75228 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10convert a helper method to be a static function instead of a Chris Lattner
template. Also convert it to take a MachineOperand instead of a GV* git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75227 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10We don't need separate thumb1 instructions tADDSi3 etc. for addc and subc. ↵Evan Cheng
The "normal" version always modify condition register CPSR so we should just use def : pat to match to the same instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75219 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10ImmutableMap/ImmutableSet: Allow caching of ImutAVLTree digests while the treeTed Kremenek
is still mutable. My experiments show this reduces the amount of times we compute a full tree digest by over 50% on very small cases, and potentially much larger on others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75207 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-09Revert the part of 75177 that split ConstantRange into two classes, andDan Gohman
merge the new functionality and unittests into ConstantRange. Thanks to Nick Lewycky for pointing out that it isn't necessary to have two separate classes here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75191 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-09If -fomit-frame-pointer is used, we still need to record when the %esp registerBill Wendling
is modified. Otherwise, the unwinder will get confused. The old code (before I started my hacking) did this. It dropped on the floor, because I wasn't aware of this requirement. On the plus side, if we use "alloca" in a function, we create frame pointers even with -fomit-frame-pointer is enabled! This is a Good Thing(tm)!!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75183 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-09Add a ConstantSignedRange class, which does for signed integersDan Gohman
what ConstantRange does for unsigned integers. Factor out a common base class for common functionality. Add some new functions for performing arithmetic on constant ranges. Some of these are currently just stubbed out with conservative implementations. Add unittests for ConstantRange and ConstantSignedRange. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75177 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-09Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned Eli Friedman
value. Adjust other code to deal with that correctly.
