similar to: [LLVMdev] Adding register allocator to LLVM

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 all! I didn't manage to link my regalloc to lli (I added USEDLIBS to its makefile). Without it I can't run tests cause they need lli to be built. So how can I link createMyRegisterAllocator function to lli? Thanks.

Another note: with this new functionality you should be able to dynamically load register

Hi! I've did what Jim Laskey wrote but llc didn't reckognize my regalloc option. So I moved my allocator implementation into seperate folder within CodeGen and wrote separate makefile for it (like in "Writing an LLVM pass" tutorial). But when I run "make" from LLVMOBJDIR it doesn't enter the RegAlloc directory and when linking llc an error like

Hi all I'm writing a pass for the llc tool. If I try to load my pass(llc -load ../mypass.so), this error message appears : Error opening '/nfs/wsi/ti/graumann/llvm-2.5/Release/lib/LLVMMicha.so': /nfs/wsi/ti/graumann/llvm-2.5/Release/lib/LLVMMicha.so: undefined symbol: _ZTVN12_GLOBAL__N_119MyRegisterAllocatorE -load request ignored. Is this code wrong for the pass

I did so from the first time and I also needed to add my library .a file to the USEDLIBS variable within llc makefile to build llc. I wonder how lli links with all the rest LLVM as it seems to include no lib within its makefile. May be I need to

Dear Anton, you can add your register allocator strait iin the "lib/CodeGen/Passes.cpp", and then 're-make' it: "makellvm llc", on the top of lib/CodeGen. It is faster than running make from LLVMOBJDIR. The problem is that it only add to llc the changes on the lib/CodeGen directory. If you change other parts, a make from LLVMOBJDIR will synchronize it. Try adding

This allows the use of shadow stack from the llvm-c API. I am not sure this is the place to insert the include, though.

Hi! I developed a register allocator within LLVM and now I need to test its efficiency. Can I do this using llvm-test package? Do llvm tests check all available regalloc options automatically? If not, then what modifications should I do to the test files? It would be great if I could test my algo along with linearscan and compare the results. Thanks. Tony. -- "Nae king! Nae quin! Nae

May be I need to include/link my lib somewhere else? Ah, that's probably it. Try

I've completed a survey of llvm for unnecessary dependencies on libstdc++, and on conflicts with the upcoming C++0X standard, and am recommending several changes in the enclosed patch (created with svn diff). Here is a summary of the patch: --- #include <cstdlib> added to LinkAllVMCore.h and LinkAllCodegenComponents.h to declare std::getenv. Changed next(...) to llvm::next(...) in
