I have a patch for this kind of thing attached. Please take a look and let me know if it looks

Hi all, The "Creating new registries" part on the "Writing An LLVM Pass" page seems unclear. I copied "llvm/CodeGen/RegAllocRegistry.h" to my project directory, modify the class name and the FunctionPassCtor type, and add code in the document to my "machinepass.cpp" file. But the llc -help doesn't show anything about the registry. Which part is

Hello , I have written a very simple MachineFunction Pass that currently does nothing. It compiles fine but when I try to load it with llc it give me following error: llc -optimize-regalloc=0 -load lib/GCRA.dylib -regalloc=gc test/fibo.bc Pass 'Bundle Machine CFG Edges' is not initialized. Verify if there is a pass dependency cycle. What is going wrong here ? Here is my very simple

Welcome to the world of pluggable machine passes. This work was done to lighten the load of some llvm tools, ie., only link in the register allocators and instruction schedulers that are actually needed in a particular circumstance. I guess I will have to write this up, but generally it works like this. In your register allocator .cpp file add the following include; #include

Hi! I'm developing a register allocator and need it to be available as an option for llc tool. I used to edit /lib/CodeGen/Passes.cpp for this aim but after yesterday's update these options are defined somewhere else and I can't find the place. Thanks for your help.

Hi Nicolas and Dan, Thanks for your replies. I've been playing around with various setting, as you suggested. > What version of LLVM are you using here? I'm using 2.4 My original time ratios of reg-alloc to instruction selection (1:12) referred to the local register allocator and the standard instruction selector (all passes), not a sensible comparison, I realise. > I did

Hello Team, Good Morning!! This is Vishnu Prasanth doing my master's thesis on improving llvm compiler optimization. Currently I am trying to build dragon egg and when I gave take, it is not getting recognized for ARM machine. Can you please help me with. Below are the errors when I gave the below command inside dragon egg directory GCC=GCC_DIR/gcc

Sorry for the rapid fire replies, but this configuration works for me: install(DIRECTORY include/ DESTINATION include # FILES_MATCHING PATTERN "*.def" PATTERN "*.h" PATTERN "*.td" PATTERN "*.inc" PATTERN ".svn" EXCLUDE ) install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/include/ DESTINATION include # FILES_MATCHING PATTERN

Thanks Lang, we are making progress! I no longer get the failed assertion, but the code I'm using for vregs that don't get allocated a preg, and thus need to be spilled and re-loaded is causing assembler errors. I suspect the problem is my code for allocating space in the stack, but I don't know how to fix it. I've attached a new version of the simple register-allocation

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel

Hi Susan, In x86-64 the REX prefix must be used to access an extended register (r8-r15 and their aliases), but cannot be used when accessing the high byte of the ABCD regs (AH, BH, CH, DH). In your test case you have hardcoded %vreg1 to R8B, and %vreg15 to AH, and the test case contains a copy between these registers. The copy simultaneously must have a REX prefix, and cannot have a REX prefix,
