Hello, I have written a pass for the IR and I can run it with opt -load lib/LLVMMyPass.so -mypass -myarguments -S -o output.ll < output.bc I have registered my pass with the following code: static RegisterPass<MyPass> X("mypass", "MyPass Pass (with getAnalysisUsage implemented)"); How do I include the same pass in the clang driver. I tried running the pass: clang

Hi Eli, I have tried that: static void registerMyPass(const PassManagerBuilder &, llvm::legacy::PassManagerBase &PM) { PM.add(new MyPass()); } static RegisterStandardPasses RegisterMyPass(PassManagerBuilder::EP_OptimizerLast, registerMyPass); It still couldn't find my pass.

I tried to compile this snippet of C++ code: void FuncTest() {     int* a = new int;     int* b = new int[2]; } using: clang test.cpp -S -emit-llvm -o - > test.llvm and obtained this: define void @_Z8FuncTestv() { entry:   %a = alloca i32*, align 4   %b = alloca i32*, align 4   %call = call noalias i8* @_Znwj(i32 4)   %0 = bitcast i8* %call to i32*   store i32* %0, i32** %a, align 4  

Hi, I'm having problems while using a custom pass with opt. The pass compiles and links just fine but, when I try to use it with opt: opt -load LLVMmyPass.so -my-flag -f aes.bc -o aes_bb.bc opt refuses to load it with the following error: Error opening 'LLVMmyPass.so': LLVMmyPass.so: undefined symbol: _ZN4llvm9DebugFlagE -load request ignored. and then complains that the flag

I am trying to write a MachineFunction pass and build it as a loadable module. I want the pass to run after prolog/epilog emmiter. So far, I have been using MachineFunctionPass, but by inserting it to lib/Codegen and hacking the LLVMTargetMachine file, and Pass.h files. I have created a directory "lib/Transforms/MyPass", and inside I have the code of the pass (which is just a

Hello everyone, I'm new to LLVM (which is a really great project by the way) and I hope this is the right place for my question. In the LLVM Language Reference Manual I found the "jumptable" function attribute, which seems to be exactly what I need for my project (where I want to add one level of indirection to every function call), but I have trouble figuring out, how to use

If you're on the new Makefile system, you will want to update your Makefile.rules. The patch below provides some important fixes for parallel builds and dependencies. It also adds some new features like the -local targets. For example, you can now build "all-local" to build the local directory without recursing into subdirectories. See the comments below for details of the change.

As others have mentioned, C++ mangles names (i.e., it changes the name of a symbol into a string that contains both the name, scope, and type of the variable or function), so if you know what the mangled name is of your allocator, you can recognize it. Additionally, I believe that functions with return values marked with the noalias attribute are, essentially, memory allocators because the

Hi ! Here is the situation. I created a pass in lib/Transforms/Obfuscation. I added a createFlattening() in IPO.h and in my code to be able to use it in PassManagerBuilder.cpp (lib/Transforms/IPO) in the method PopulateModulePassManager() so I can add my pass to standard passes. It all works if I add all my files in the lib/Transforms/IPO directory. But I want to keep them away in the

Hi all, A question about statically linking a pass to clang instead of dynamically loading it at runtime. I am stumped on this bug for a while. I inserted a pass under lib/Transforms/mypass directory, registered it with INITIALIZE_PASS and defined createMyPass in the pass. Also I added file mypass.h in include/llvm/Transforms/ to expose the accessor functions that expose my passes. Entries are

Hi I have written a pass which creates some scheduling information. Its called MParSchedule. This pass works with opt. But when feeding it my experimental backend it seems to loose instructions and fails to work. I am loading this stuff as .so libraries under linux and i am using the amd64 version with a self compiled llvm-gcc. With this call it works: opt

Hello everyone, I'm trying to load and run a pass on Cygwin target: opt -load=mypass.dll -mypass There is an LLVM example - Hello, however lib/Transforms/Makefile says # No support for plugins on windows targets and then excludes Hello from build ifeq ($(HOST_OS), $(filter $(HOST_OS), Cygwin MingW Minix)) PARALLEL_DIRS := $(filter-out Hello, $(PARALLEL_DIRS)) endif On the other hand, I

Hi guys, I am writing a LLVM pass plugin, and just simply add a directory mypass into llvm/lib/Transforms. But since I don't hope this directory to contain too many source files, I add some subdirectories. For instance, there are 2 files inside *mypass/sub: basic.h, basic.cpp. Here is the structure of the directory llvm/lib/Transforms/mypass $tree mypass mypass ├── Makefile ├──
