* CorrelatedPropagation: BasicBlock::removePredecessor can simplify PHI nodes. ↵Benjamin Kramer2012-09-281-0/+5

* GlobalOpt: non-constexpr bitcasts or GEPs can occur even if the global value ↵Benjamin Kramer2012-09-281-1/+3

* Surprisingly, we missed a trivial case here. Fix that!Nick Lewycky2012-09-281-0/+4
| | | | llvm-svn: 164814
* 1. Add load/store words from the stackReed Kotler2012-09-283-34/+86
| | | | | | | | | 2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and moved other lines for FEXT_RI16 formats to be in the right place in the code. 3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment. 4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem. llvm-svn: 164811
* Remove <def,read-undef> flags from partial redefinitions.Jakob Stoklund Olesen2012-09-271-0/+6
| | | | | | | | | The new coalescer can turn a full virtual register definition into a partial redef by merging another value into an unused vector lane. Make sure to clear the <read-undef> flag on such defs. llvm-svn: 164807
* Enable the new coalescer algorithm by default.Jakob Stoklund Olesen2012-09-271-1/+1
| | | | | | | The new coalescer is better at merging values into unused vector lanes, improving NEON code. llvm-svn: 164794
* Don't dereference begin() on an empty vector.Jakob Stoklund Olesen2012-09-271-1/+1
| | | | | | | | The fix is obvious and the only test case I have is horrible, so I am not including it. The problem shows up when self-hosting clang on i386 with -new-coalescer enabled. llvm-svn: 164793

* Fix a integer overflow in SimplifyCFG's look up table formation logic.Benjamin Kramer2012-09-271-0/+4
| | | | | | | | If the width is very large it gets truncated from uint64_t to uint32_t when passed to TD->fitsInLegalInteger. The truncated value can fit in a register. This manifested in massive memory usage or crashes (PR13946). llvm-svn: 164784
* Avoid dereferencing a NULL pointer.Jakob Stoklund Olesen2012-09-271-1/+1
| | | | | | Fixes PR13943. llvm-svn: 164778

* [arm-fast-isel] Add support for ELF PIC.Jush Lu2012-09-275-2/+123
| | | | | | | This is a preliminary step towards ELF support; currently ARMFastISel hasn't been used for ELF object files yet. llvm-svn: 164759

* MIPS DSP: add bitcast patterns between vectors and int.Akira Hatanaka2012-09-271-0/+10
| | | | | | No test cases. These patterns will get tested along with dsp intrinsics. llvm-svn: 164746

* Query the parameter attributes directly instead of using the Attribute symbols.Bill Wendling2012-09-261-5/+5
| | | | llvm-svn: 164727
* Remove the `hasFnAttr' method from Function.Bill Wendling2012-09-2630-52/+52
| | | | | | | The hasFnAttr method has been replaced by querying the Attributes explicitly. No intended functionality change. llvm-svn: 164725
* X86_32: Large Symbol+Offset relocations.Jim Grosbach2012-09-261-8/+40
| | | | | | | | | | If the offset is more than 24-bits, it won't fit in a scattered relocation offset field, so we fall back to using a non-scattered relocation. rdar://12358909 llvm-svn: 164724
* Initial commit for the AttributesImpl class.Bill Wendling2012-09-264-1/+84
| | | | | | | | This opaque class will contain all of the attributes. All attribute queries will go through this object. This object will also be uniqued in the LLVMContext. Currently not used, so no implementation change. llvm-svn: 164722

| | | | | | | teach the callgraph logic to not create callgraph edges to intrinsics for invoke instructions; it already skips this for call instructions. Fixes PR13903. llvm-svn: 164707
