...BB and print out the values computed in that BB that are live at the end of the BB (so we don't print out temporaries computed and used within the BB), and we also print out values that are loaded or stored from/to memory. You need to link the generated code with /localhome/vadve/llvm/runtime/libtrace/Bytecode/tracelib.bc or /localhome/vadve/llvm/runtime/libtrace/Debug/libtrace.o. Try: % cd test/Programs/SingleSource/Shootout/ % gmake -n TRACE=yes Output/sieve.diff-llc as an example to see how to run the tracing pass and link the generated code. --Vikram http://www.cs.uiuc.edu/~vadve -----...

no expression parser or knowledge of any specific programming language. Basically I just mean that the parsing of the native DWARF format itself is in scope, but anything beyond that is out of scope. For symbolication we have things like llvm-symbolizer that already just work and are built on top of LLVM's dwarf parsing code. Similarly, LLDB's type system could be built on top of it as

Hi all, We have been thinking internally about a lightweight llvm-based ptracer. To address one question up front: the primary way in which this differs from LLDB is that it targets a more narrow use case -- there is no scripting support, no clang integration, no dynamic extensibility, no support for running jitted code in the target, and no user interface. We have several use cases internally

Hi llvmer, I am trying to learn how to use llvm. My question is described as the following, there has already a testcase code, and I get bytecode by using llvmgcc. What I want to do is to insert a call funcation into each basic block, which is for statistic some information. 1) I implement call function in another c/cpp file and can I insert the external call function to existed bytecode ? if it

You'd probably need to pull the Unwinder in if you want backtraces, but that part shouldn't be that hard to disentangle. I don't think you'd need much else? Basing your work on NativeProcess rather than lldb proper would also cut the number of observer processes in half and avoid the context switches between the server and the debugger. That seems more appropriate for a

For the field pointer, one could use the getelementptr instruction: %pairty = { sbyte, sbyte, int* } %pairPtr = ... %fieldptr = getelementptr
