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 responsible for making the part ofcl::opt code? Can anyone sh...

...nly 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 ""llvm/CodeGen/RegAllocRegistry.h"" In your register allocator .cpp file define a create function in the form; FunctionPass *createMyRegisterAllocator() { return new MyRegisterAllocator(); } and the "installing" static constructor declaration, in the form; static RegisterRegAlloc myRegAlloc...

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

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,
