...r in and out. One of the first ideas was to use a kind of configuration file, since the kernel developer knows about the data directions. But I think this can be done more elegant. Anyway, based on your answer I'll maybe go back to this idea.

...* bitcast (i32* @f to i8*) . Do you know how I can get the name @f from this? I cannot convert it again to ConstantStruct and follow the same procedure, it will give me a segfault.

Hello everyone ! I followed http://stackoverflow.com/questions/4976298/modern-equivalent-of-llvm-annotationmanagerin order to get annotations from my target bytecode. All the examples that I give in the following is related to the code from that link. I have `__attribute__((annotate("DS"))) int f=0;` into the target C++ program and the related IR code: @.str = private unnamed_addr

First, let me ask if there's a page that documents the testing process in full. If there is, just give me a link to that and save yourself the time of answering this. (I did Google it, all I found was docs on writing tests for LLVM.) Sorry if this is way off, but I have no idea what to download and unpack to start testing. I know it's stuff from here:

Hello, LLVM provides several ways to visual IR structure straight in its core - Function::viewCFG() to render control flow graph, then -view-* options to llc to render various stages of transforming to machine code. However, I wasn't able to find a way to render complete DAG visualization of normal IR - which besides CFG would also show dataflow (and other flows, if any). What people use to

Hi, We would like to inform the community that we're releasing a version of our research compiler, "AESOP", developed at UMD using LLVM. AESOP is a distance-vector-based autoparallelizing compiler for shared-memory machines. The source code and some further information is available at http://aesop.ece.umd.edu The main components of the released implementation are loop memory
