* Merge r168037 from trunk:Hans Wennborg2012-11-16
| | | | | | | | | | | | | | | | | Make GlobalOpt be conservative with TLS variables (PR14309) For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168192 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | These changes fix a serious interaction problem with the cost model on x86 that could cause the vectorizer to enter an infinite loop (and sometimes crash in other ways). git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@167993 91177308-0d34-0410-b5e6-96231b3b80d8

* [NVPTX] Add more precise PTX/SM target attributesJustin Holewinski2012-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167699 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove hard-coded constant in Transforms/InstCombine/memcmp-1.llMeador Inge2012-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167691 91177308-0d34-0410-b5e6-96231b3b80d8

* Add method for replacing instructions to LibCallSimplifierMeador Inge2012-11-11
| | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167681 91177308-0d34-0410-b5e6-96231b3b80d8

* instcombine: Query target library information to gate libcall simplificationsMeador Inge2012-11-10
| | | | | | | | | Several of the simplifiers migrated from the simplify-libcalls pass to the instcombine pass were not correctly checking the target library information to gate the simplifications. This patch ensures that the check is made. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167660 91177308-0d34-0410-b5e6-96231b3b80d8
* Add more functions to the target library information.Meador Inge2012-11-10
| | | | | | | | | | | In the process of migrating optimizations from the simplify-libcalls pass to the instcombine pass I noticed that a few functions are missing from the target library information. These functions need to be available for querying in the instcombine library call simplifiers. More functions will probably be added in the future as more simplifiers are migrated to instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167659 91177308-0d34-0410-b5e6-96231b3b80d8
