* Disable the PPC CTR-Loops pass by default.Hal Finkel2012-06-084-6/+19
| | | | | | | | | | The pass itself works well, but the something in the Machine* infrastructure does not understand terminators which define registers. Without the ability to use the block-placement pass, etc. this causes performance regressions (and so is turned off by default). Turning off the analysis turns off the problems with the Machine* infrastructure. llvm-svn: 158206
* Fix a bug in the new PPC CTR-Loops pass.Hal Finkel2012-06-082-0/+88
| | | | | | | | | The code which tests for an induction operation cannot assume that any ADDI instruction will have a register operand because the operand could also be a frame index; for example: %vreg16<def> = ADDI8 <fi#0>, 0; G8RC:%vreg16 llvm-svn: 158205
* Add the PPCCTRLoops pass: a PPC machine-code-level optimization pass to form ↵Hal Finkel2012-06-0810-18/+890
| | | | | | | | | | CTR-based loop branching code. This pass is derived from the Hexagon HardwareLoops pass. The only significant enhancement over the Hexagon pass is that PPCCTRLoops will also attempt to delete the replaced add and compare operations if they are no longer otherwise used. Also, invalid preheader DebugLoc is not used. llvm-svn: 158204

* Revert commit 158073 while waiting for a fix. The issue is that reassociateDuncan Sands2012-06-082-111/+144
| | | | | | | | | | | | | | | | can move instructions within the instruction list. If the instruction just happens to be the one the basic block iterator is pointing to, and it is moved to a different basic block, then we get into an infinite loop due to the iterator running off the end of the basic block (for some reason this doesn't fire any assertions). Original commit message: Grab-bag of reassociate tweaks. Unify handling of dead instructions and instructions to reoptimize. Exploit this to more systematically eliminate dead instructions (this isn't very useful in practice but is convenient for analysing some testcase I am working on). No need for WeakVH any more: use an AssertingVH instead. llvm-svn: 158199

* cmake: Pass the -m32 flag to modules if LLVM_BUILD_32_BITS is enabledTobias Grosser2012-06-081-0/+1
| | | | | | | | | | | This was previously only done for executables and shared libraries, but not for modules. As modules are essentially shared libraries (that need to be dlopened explicitly), threating them the same as shared libraries seems reasonable. This fixes the LLVM_BUILD_32_BITS build of Polly.

* [libclang/AST]Argyrios Kyrtzidis2012-06-083-3/+29
| | | | | | | | | | | | | AST: For auto-synthesized ivars give them the location of the related property (previously they had no source location). This allows them to be indexed by libclang. libclang: Make sure synthesized ivars are indexed before the methods that may reference them. Fixes rdar://11607001. llvm-svn: 158189
* Committed a change to the SectionList that introducesSean Callanan2012-06-087-15/+109
| | | | | | | | | | | a cache of address ranges for child sections, accelerating lookups. This cache is built during object file loading, and is then set in stone once the object files are done loading. (In Debug builds, we ensure that the cache is never invalidated after that.) llvm-svn: 158188

* [analyzer] Add experimental "issue hash" to the plist diagnostic.Anna Zaks2012-06-085-0/+48
| | | | | | | | | | | | | | CmpRuns.py can be used to compare issues from different analyzer runs. Since it uses the issue line number to unique 2 issues, adding a new line to the beginning of a file makes all issues in the file reported as new. The hash will be an opaque value which could be used (along with the function name) by CmpRuns to identify the same issues. This way, we only fail to identify the same issue from two runs if the function it appears in changes (not perfect, but much better than nothing). llvm-svn: 158180

* X86: optimize generated code for integer ABSManman Ren2012-06-072-8/+54
| | | | | | | | | | | | | | | | | | | | This patch will generate the following for integer ABS: movl %edi, %eax negl %eax cmovll %edi, %eax INSTEAD OF movl %edi, %ecx sarl $31, %ecx leal (%rdi,%rcx), %eax xorl %ecx, %eax There exists a target-independent DAG combine for integer ABS, which converts integer ABS to sar+add+xor. For X86, we match this pattern back to neg+cmov. This is implemented in PerformXorCombine. rdar://10695237 llvm-svn: 158175

* Fix many doxygen formatting errors.Chandler Carruth2012-06-075-71/+74
| | | | | | | | | | | | | This patch affects docs only, and includes formatting changes only (though those include some fixes for broken Doxygen markup that caused some content to be missing from generated pages). It avoids generating many spurious pages such as http://clang.llvm.org/doxygen/classRepresents.html, but likely not all yet. Patch by James Dennett. llvm-svn: 158155

* Plug a long standing memory leak in TemplateArgument.Benjamin Kramer2012-06-0717-103/+79
| | | | | | | | | | | | | | | The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. llvm-svn: 158150
