* Remove a wrapper around getIntPtrType added to GVN by Hal in commit 166624 (theDuncan Sands2012-10-295-25/+19
| | | | | | | | | wrapper returns a vector of integers when passed a vector of pointers) by having getIntPtrType itself return a vector of integers in this case. Outside of this wrapper, I didn't find anywhere in the codebase that was relying on the old behaviour for vectors of pointers, so give this a whirl through the buildbots. llvm-svn: 166939
* Remove code to saturate profile counts.Bob Wilson2012-10-291-8/+1
| | | | | | | | | We may need to change the way profile counter values are stored, but saturation is the wrong thing to do. Just remove it for now. Patch by Alastair Murray! llvm-svn: 166938

* This patch addresses a problem with the Post RA scheduler generating anPreston Gurd2012-10-291-0/+5
| | | | | | | | | | | | | | incorrect instruction sequence due to it not being aware that an inline assembly instruction may reference memory. This patch fixes the problem by causing the scheduler to always assume that any inline assembly code instruction could access memory. This is necessary because the internal representation of the inline instruction does not include any information about memory accesses. This should fix PR13504. llvm-svn: 166929
* This patch adds alignment information for long double to the 64-bit PowerPCBill Schmidt2012-10-291-0/+6
| | | | | | | | | | | | | | | | | ELF subtarget. The existing logic is used as a fallback to avoid any changes to the Darwin ABI. PPC64 ELF now has two possible data layout strings: one for FreeBSD, which requires 8-byte alignment, and a default string that requires 16-byte alignment. I've added a test for PPC64 Linux to verify the 16-byte alignment. If somebody wants to add a separate test for FreeBSD, that would be great. Note that there is a companion patch to update the alignment information in Clang, which I am committing now as well. llvm-svn: 166928
* Factorize code: rather than duplication the logic in getPointerTypeSizeInBits,Duncan Sands2012-10-291-14/+2

* llvm-extract changes linkages so that functions on both sides of theRafael Espindola2012-10-291-12/+25
| | | | | | | split module can see each other. If it is keeping a symbol that already has a non local linkage, it doesn't need to change it. llvm-svn: 166908
* llvm-extract was unable to handle aliases. It would leave a copy on theRafael Espindola2012-10-291-0/+30
| | | | | | | | | | | | | | | | | | output of both llvm-extract foo.ll -func=bar and llvm-extract foo.ll -func=bar -delete so the two new files could not be linked together anymore. With this change alias are handled almost like functions and global variables. Almost because with alias we cannot just clear the initializer/body, we have to create a new declaration and replace the alias with it. The net result is that now the output of the above commands can be linked even if foo.ll has aliases. llvm-svn: 166907

* This patch is for the implementation of mips16 complex pattern addr16.Reed Kotler2012-10-287-48/+276
| | | | | | | | | | | | | | | | | | | | | Previously mips16 was sharing the pattern addr which is used for mips32 and mips64. This had a number of problems: 1) Storing and loading byte and halfword quantities for mips16 has particular problems due to the primarily non mips16 nature of SP. When we must load/store byte/halfword stack objects in a function, we must create a mips16 alias register for SP. This functionality is tested in stchar.ll. 2) We need to have an FP register under certain conditions (such as dynamically sized alloca). We use mips16 register S0 for this purpose. In this case, we also use this register when accessing frame objects so this issue also affects the complex pattern addr16. This functionality is tested in alloca16.ll. The Mips16InstrInfo.td has been updated to use addr16 instead of addr. The complex pattern C++ function for addr has been copied to addr16 and updated to reflect the above issues. llvm-svn: 166897
* Never attempt to join an early-clobber def with a regular kill.Jakob Stoklund Olesen2012-10-271-0/+14

* LoopIdiom: Add checks to avoid turning memmove into an infinite loop.Benjamin Kramer2012-10-271-2/+2
| | | | | | I don't think this is possible with the current implementation but that may change eventually. llvm-svn: 166877
* LoopIdiom: Recognize memmove loops.Benjamin Kramer2012-10-271-10/+24
| | | | | | | | | | | This turns loops like for (unsigned i = 0; i != n; ++i) p[i] = p[i+1]; into memmove, which has a highly optimized implementation in most libcs. This was really easy with the new DependenceAnalysis :) llvm-svn: 166875
* LoopIdiom: Replace custom dependence analysis with DependenceAnalysis.Benjamin Kramer2012-10-271-80/+45
| | | | | | | | | | | Requires a lot less code and complexity on loop-idiom's side and the more precise analysis can catch more cases, like the one I included as a test case. This also fixes the edge-case miscompilation from PR9481. Compile time performance seems to be slightly worse, but this is mostly due to an extra LCSSA run scheduled by the PassManager and should be fixed there. llvm-svn: 166874

* Update BBVectorize to use the new VTTI instr. cost interfaces.Hal Finkel2012-10-271-3/+58
| | | | | | | | The monolithic interface for instruction costs has been split into several functions. This is the corresponding change. No functionality change is intended. llvm-svn: 166865
