[llvm-dev] Building and Invoking DSA or Pool Alloc

[Mani, Suresh via llvm-dev]

Hi ,

This Is 'Suresh M' from AMD compiler team.


1)      I obtained the source code of llvm and pool-alloc  (relase_32 versions ) using the following commands,



svn co http://llvm.org/svn/llvm-project/llvm/branches/release_32 llvm

cd llvm/projects

svn co http://llvm.org/svn/llvm-project/poolalloc/branches/release_32 poolalloc


2)      Was able to build the binaries and libraries
                          ../rel_32/build_rel/projects/poolalloc/Release+Asserts/lib
-rw-rw-r-- 1 sumani sumani  987956 Apr 15 15:56 AssistDS.a

-rwxrwxr-x 1 sumani sumani   23861 Apr 15 15:56 typechecks_rt.so

                               ../rel_32/build_rel/Release+Asserts/bin          // Contains the llvm binaries
                               ../rel_32/build_rel/Release+Asserts/lib           // Contains the llvm libraries




3)      Invoking opt as follows,

               ../rel_32/build_rel/Release+Asserts/bin/opt -load ../rel_32/build_rel/projects/poolalloc/Release+Asserts/lib/poolalloc.so   --help
                  Error opening ../rel_32/build_rel/projects/poolalloc/Release+Asserts/lib/poolalloc.so: ../rel_32/build_rel/projects/poolalloc/Release+Asserts/lib/poolalloc.so: undefined symbol: _ZN4llvm21EquivBUDataStructures2IDE
                 -load request ignored.
                  OVERVIEW: llvm .bc -> .bc modular optimizer and analysis printer
                  USAGE: opt [options] <input bitcode file>

                  OPTIONS:
                    -O1                                          - Optimization level 1. Similar to clang -O1
                    -O2                                          - Optimization level 2. Similar to clang -O2
                    -O3                                          - Optimization level 3. Similar to clang -O3
                         :
                         :


Can anyone please do let me know how this could be resolved.

Thanks
M Suresh
