* LoopVectorizer: Extend the induction variable to a larger typeArnold Schwaighofer2013-11-182-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some case the loop exit count computation can overflow. Extend the type to prevent most of those cases. The problem is loops like: int main () { int a = 1; char b = 0; lbl: a &= 4; b--; if (b) goto lbl; return a; } The backedge count is 255. The induction variable type is i8. If we add one to 255 to get the exit count we overflow to zero. To work around this issue we extend the type of the induction variable to i32 in the case of i8 and i16.

* test-release.sh: tweak RPATH for the binary packages.Arnaud A. de Grandmaison2013-11-181-0/+32
| | | | | | | | libtool sets RPATH to "$ORIGIN/../lib:/the/directory/where/it/was/built/lib" so that a developper can use the built or the installed version seamlessly. Our binary packages should not have this developer friendly tweak, as the users of the binaries will not have the build tree. Beside, in case the development tree is a possibly on an automounted share, this can create very bad user experience : they will incur an automount timeout penalty and will get a very bad feeling of llvm/clang's speed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194999 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert r194865 and r194874.Alexey Samsonov2013-11-18115-500/+152
| | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Verifier: disable it by default.Manman Ren2013-11-181-1/+1
| | | | | | | | | | | | | | | Debug info verifier is part of the verifier which is a Function Pass. Tot currently tries to pull all reachable debug info MDNodes in each function, which is too time-consuming. The correct fix seems to be separating debug info verification to its own module pass. I will disable the debug info verifier until a correct fix is found. For Bill's testing case, enabling debug info verifier increase compile time from 11s to 11m. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194986 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Verifier: fix when to find debug info nodes and when to verify them.Manman Ren2013-11-171-5/+11
| | | | | | | | | | | | | | | | | | | We used to collect debug info MDNodes in doInitialization and verify them in doFinalization. That is incorrect since MDNodes can be modified by passes run between doInitialization and doFinalization. To fix the problem, we handle debug info MDNodes that can be reached from a function in runOnFunction (i.e we collect those nodes by calling processDeclare, processValue and processLocation, and then verify them in runOnFunction). We handle debug info MDNodes that can be reached from named metadata in doFinalization. This is in line with how Verifier handles module-level data (they are verified in doFinalization). rdar://15472296 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194974 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info Verifier: enable public functions of Finder to update the type map.Manman Ren2013-11-173-11/+29
| | | | | | | | | | | We used to depend on running processModule before the other public functions such as processDeclare, processValue and processLocation. We are now relaxing the constraint by adding a module argument to the three functions and letting the three functions to initialize the type map. This will be used in a follow-on patch that collects nodes reachable from a Function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194973 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | As the "LLVMInitializeAll*" functions are not available as symbols in the shared library they can't be used, and as a workaround a list of the targets is kept and the individual symbols tried.
