2012-11-13Fix a Malloc Checker FP by tracking return values from initWithCharacterllvmorg-3.2.0-rc1Anna Zaks2-20/+132
and other functions. When these functions return null, the pointer is not freed by them/ownership is not transfered. So we should allow the user to free the pointer by calling another function when the return value is NULL. Commits: 167813, 167814, 167868 llvm-svn: 167870

2012-11-13[analyzer] Follow up to r167762 - precisely determine the adjustmentAnna Zaks2-4/+52
conditions. The adjustment is needed only in case of dynamic dispatch performed by the analyzer - when the runtime declaration is different from the static one. Document this explicitly in the code (by adding a helper). Also, use canonical Decls to avoid matching against the case where the definition is different from found declaration. This fix suppresses the testcase I added in r167762, so add another testcase to make sure we do test commit r167762. llvm-svn: 167797

attributes. In cases where the merged declaration is fully equivalent to the two original ones, some of the code was getLVForDecl was duplicated. Cases that are still handled in getLVForDecl are things like __private_extern__ int N; int N; For which we cannot produce a single merged decl with all the information. llvm-svn: 167703

2012-11-12[NVPTX] Add more precise PTX/SM target attributesJustin Holewinski14-11/+117
Each SM and PTX version is modeled as a subtarget feature/CPU. Additionally, PTX 3.1 is added as the default PTX version to be out-of-the-box compatible with CUDA 5.0. Available CPUs for this target: sm_10 - Select the sm_10 processor. sm_11 - Select the sm_11 processor. sm_12 - Select the sm_12 processor. sm_13 - Select the sm_13 processor. sm_20 - Select the sm_20 processor. sm_21 - Select the sm_21 processor. sm_30 - Select the sm_30 processor. sm_35 - Select the sm_35 processor. Available features for this target: ptx30 - Use PTX version 3.0. ptx31 - Use PTX version 3.1. sm_10 - Target SM 1.0. sm_11 - Target SM 1.1. sm_12 - Target SM 1.2. sm_13 - Target SM 1.3. sm_20 - Target SM 2.0. sm_21 - Target SM 2.1. sm_30 - Target SM 3.0. sm_35 - Target SM 3.5. llvm-svn: 167699

2012-11-11Fix binding of nodes in case of forEach..() matchers.Daniel Jasper4-7/+19
When recursively visiting the generated matches, the aggregated bindings need to be copied during the recursion. Otherwise, we they might not be properly overwritten (which is shown by the test), or there might be bound nodes present that were bound on a different matching branch.

2012-11-11Remove hard-coded constant in Transforms/InstCombine/memcmp-1.llMeador Inge1-1/+10
Transforms/InstCombine/memcmp-1.ll has a test case that looks like: @foo = constant [4 x i8] c"foo\00" @hel = constant [4 x i8] c"hel\00" ... %mem1 = getelementptr [4 x i8]* @hel, i32 0, i32 0 %mem2 = getelementptr [4 x i8]* @foo, i32 0, i32 0 %ret = call i32 @memcmp(i8* %mem1, i8* %mem2, i32 3) ret i32 %ret ; CHECK: ret i32 2 The folded return value (2 above) is computed using the system memcmp that the compiler is linked with. This can return different values on different systems. The test was originally written on an OS X 10.7.5 x86-64 box and passed. However, it failed on one of the x86-64 FreeBSD buildbots because the system memcpy on that machine returned a different value (1 instead of 2). I fixed the test by checking the folding constants with regexes. llvm-svn: 167691

2012-11-11Add method for replacing instructions to LibCallSimplifierMeador Inge3-6/+44
In some cases the library call simplifier may need to replace instructions other than the library call being simplified. In those cases it may be necessary for clients of the simplifier to override how the replacements are actually done. As such, a new overrideable method for replacing instructions was added to LibCallSimplifier. A new subclass of LibCallSimplifier is also defined which overrides the instruction replacement method. This is because the instruction combiner defines its own replacement method which updates the worklist when instructions are replaced. llvm-svn: 167681
