* Perform two more constructor/destructor code-size optimizations:John McCall2010-02-2314-60/+425
| | | | | | | | | | | | | | | | 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842

* Implement crazy destructor name lookup semantics differently inDouglas Gregor2010-02-235-15/+134
| | | | | | | | | | C++98/03 and C++0x, since the '0x semantics break valid C++98/03 code. This new mess is tracked by core issue 399, which is still unresolved. Fixes PR6358 and PR6359. llvm-svn: 96836

* add a new Push2 opcode for targets (like cellspu) which haveChris Lattner2010-02-222-6/+32
| | | | | | | | ridiculously ginormous patterns and need more than one byte of displacement for encodings. This fixes CellSPU/fdiv.ll. SPU is still doing something else ridiculous though. llvm-svn: 96833

* Instcombine constant folding can normalize gep with negative index to index ↵Evan Cheng2010-02-226-15/+86
| | | | | | with large offset. 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. llvm-svn: 96825
* 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. llvm-svn: 96824
* Rework the CIndex API for displaying diagnostics. Instead of printingDouglas Gregor2010-02-225-38/+56
| | | | | | | the diagnostics to a FILE*, return a CXString containing the formatted diagnostic. llvm-svn: 96823
* 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. llvm-svn: 96822

* The predicate index isn't fixed, so scan for it to make sure we get the properJim Grosbach2010-02-221-2/+3
| | | | | | | | | value. Thumb2 uses the tADJCALLSTACK* instructions, and doesn't need t2 versions, so remove the FIXME entry. llvm-svn: 96817
* 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. llvm-svn: 96816
* expand my hack to work with nodes that have flags but no chains and the Chris Lattner2010-02-221-1/+2
| | | | | | | isel doesn't know the correct # results. This fixes 8 codegen tests, down to 22 failures. llvm-svn: 96815
* add a new CheckMultiOpcode opcode for checking that a nodeChris Lattner2010-02-225-3/+51
| | | | | | | has one of the list of acceptable opcodes for a complex pattern. This fixes 4 regtest failures. llvm-svn: 96814
* When matching patterns that have a complex pattern as their root, make Chris Lattner2010-02-221-1/+16
| | | | | | | | sure to only run the complex pattern on nodes where the target opts in. This patch only handles targets with one opcode specified so far, but fixes 16 failures, only 34 left. llvm-svn: 96813

* 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. llvm-svn: 96783
