information injected by the allocator we need to: ● Compile the code with clang into LLVM bitcode ● Implement a custom LLVM pass(es) which would be able to: ○ Compose the list of all unique allocation types Generate bucket and memory pool definitions ● Run the pass on the bitcode using the LLVM opt tool © 2020 Apex.AI, Inc.Compile the code with clang into LLVM bitcode ● The code should be compiled with: ○ -g calls ○ -emit-llvm to compile into the bitcode ○ Probably -DNDEBUG to get the Release versions of data structures Then the bitcode files can be (optionally) linked together with llvm-link © 2020 Apex

anywhere else in your project file structure. To use the configuration specified in a profile file, pass in the file as a command line argument as shown in the example below: $ conan create . demo/testing in a long list of command line arguments, we can define a handy profile that defines them all and pass that to the command line when installing the project dependencies. A profile to install dependencies 1@demo/testing The conan create command receives the same command line parameters as conan install so you can pass to it the same settings, options, and command line switches. If you want to create and test packages
