I'm having trouble understanding how APInts should be used. The APInt documentation states that it 'is a functional replacement for common case unsigned integer type', but I'm not seeing this because the internal logic is that the value is always treated as negative if the most significant bit is set. I'm interested in an add or sub that could be using a negative value. I

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method? Also, I would like to get the metadata and convert it back to integer. Thank you ! --------------...

Good day, LLVMers! We are starting on our third (and hopefully last) round of testing for LLVM 3.0. Please visit: http://llvm.org/pre-releases/3.0/rc3/ for the sources. There are also binaries for Darwin up there, with more to come during the week. Please build this release candidate, test it out on your projects, and let us know if you find any regressions from the 2.9 release. Please keep

Use of APFloat and AP[S]Int directly is the way to do this. It would be useful to extend APSInt to capture information about overflow. > If LLVM's APFloat wrapper isn't conveying the info it is given > by APFloat, it needs to be improved :) No, it doesn't.

...a (potentially lazy) value tracking analysis that could be reused by several optimization passes. I don't know if it exists in llvm or not, but to my better knowledge it does not. ok there exists the ValueTracking class, but it does not provide a function like e.g. MayHaveTheValue(Value* v, APSInt x) to check if a given var v may ever have the value x My proposal: - create a value tracking analysis interface that can provide extensive info about vars (e.g. the set of possible values for a given vars, etc..) - implement that interface in several ways with different tradeoffs of precisen...

Hello everyone, I'm trying to compile LLVM and Clang into LLVM IR with debug info. I know that clang++ -g2 -S -emit-llvm <filename> does this, but I'm unfamiliar with CMake. I tried changing CMAKE_CXX_FLAGS in CMakeCache.txt to "clang++ -g2 -S -emit-llvm," "-g2 -S -emit-llvm," and "-emit-llvm," but everything I tried resulted in a failed build, and/or

If you look in llvm/test/Integer you'll see a whole bunch of tests that really want to be unit tests but that aren't. :( -Chris
