* Instcombine constant folding can normalize gep with negative index to index ↵Evan Cheng2010-02-226-15/+86

When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96825 91177308-0d34-0410-b5e6-96231b3b80d8
* Change ComplexPattern handling to push the node being matched asChris Lattner2010-02-221-21/+13
| | | | | | | | | | | well as the operands produced when the pattern is matched. This allows CheckSame to work correctly when matching replicated names involving ComplexPatterns. This fixes a bunch of MSP430 failures, we're down to 13 failures, two of which are due to a sched bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96824 91177308-0d34-0410-b5e6-96231b3b80d8
* Updated version of r96634 (which was reverted due to failing 176.gcc andJim Grosbach2010-02-226-5/+34
| | | | | | | | 126.gcc nightly tests. These failures uncovered latent bugs that machine DCE could remove one half of a stack adjust down/up pair, causing PEI to assert. This update fixes that, and the tests now pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96822 91177308-0d34-0410-b5e6-96231b3b80d8

* The predicate index isn't fixed, so scan for it to make sure we get the properJim Grosbach2010-02-221-2/+3

* Canonicalize ConstantInts to the right operand of commutativeDan Gohman2010-02-223-3/+7
| | | | | | | | | | | operators. The test difference is just due to the multiplication operands being commuted (and thus requiring a more elaborate match). In optimized code, that expression would be folded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96816 91177308-0d34-0410-b5e6-96231b3b80d8

* add a new CheckMultiOpcode opcode for checking that a nodeChris Lattner2010-02-225-3/+51

* When matching patterns that have a complex pattern as their root, make Chris Lattner2010-02-221-1/+16

* Mark the return address stack slot as mutable when moving the return addressArnold Schwaighofer2010-02-222-2/+57
| | | | | | | | | | | | | | | | | | during a tail call. A parameter might overwrite this stack slot during the tail call. The sequence during a tail call is: 1.) load return address to temp reg 2.) move parameters (might involve storing to return address stack slot) 3.) store return address to new location from temp reg If the stack location is marked immutable CodeGen can colocate load (1) with the store (3). This fixes bug 6225. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96783 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | result nodes correctly. Note that this includes a horrible hack in DAGISelHeader which cannot be fixed reasonably without eliminating (parallel) from input patterns. That, in turn, can't be done until we support writing multiple result patterns for the X86and_flag and related multiple-result nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96767 91177308-0d34-0410-b5e6-96231b3b80d8
