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

../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:
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

[llvm-dev] Building and Invoking DSA or Pool Alloc
Dear Suresh, First, may I ask why you're using automatic pool allocation (APA)? The APA transforms have probably suffered significant bitrot; I haven't used them much in recent years. APA's current algorithms for deciding when and where to make pools are a bit complicated. Depending on your needs, it may make more sense to morph the current APA code into something that is simpler and easier to maintain (e.g., a transform that creates global, context-insensitive pools) than to use it for doing context-sensitive pool allocation (which requires changing function signatures which becomes tricky when the program uses external libraries). We've used DSA recently (Fall 2014), so it's in much better shape. We even have a version of it ported to LLVM 3.7 (https://github.com/jtcriswell/llvm-dsa). Second, to answer your question, the reason why you're seeing this error is because you haven't loaded the DSA libraries into opt. You need to include additional -load options to opt to load DSA. I believe the libraries you need to load (in order) are libAssistDS.so and libLLVMDataStructure.so: opt -load AssistDS.so -load LLVMDataStructucture.so -load poolalloc.so ... An alternative to running opt is to build a simple tool which links in these libraries and runs the needed passes over the bitcode file (essentially, writing a specialized opt tool just for running these passes). The pa programs (poolalloc/tools/Pa) is an outdated example of such a tool.

[llvm-dev] Building and Invoking DSA or Pool Alloc
Hi Criswell,
Thanks a lot for the immediate and detailed response on this.
Sure I will try using the ported version https://github.com/jtcriswell/llvm-dsa
and check.
Thanks

Dear Suresh,
First, may I ask why you're using automatic pool allocation (APA)? The APA
transforms have probably suffered significant bitrot; I haven't used them
much in recent years. APA's current algorithms for deciding when and where
to make pools are a bit complicated. Depending on your needs, it may make more
sense to morph the current APA code into something that is simpler and easier to

to use it for doing context-sensitive pool allocation (which requires changing
function signatures which becomes tricky when the program uses external
libraries).
We've used DSA recently (Fall 2014), so it's in much better shape. We
even have a version of it ported to LLVM 3.7
(https://github.com/jtcriswell/llvm-dsa).
Second, to answer your question, the reason why you're seeing this error is
because you haven't loaded the DSA libraries into opt. You need to include
additional -load options to opt to load DSA. I believe the libraries you need
to load (in order) are libAssistDS.so and libLLVMDataStructure.so:
opt -load AssistDS.so -load LLVMDataStructucture.so -load poolalloc.so ...
An alternative to running opt is to build a simple tool which links in these

a specialized opt tool just for running these passes). The pa programs
(poolalloc/tools/Pa) is an outdated example of such a tool.
