[LLVMdev] adding a codegen pass into llvm

[marwayusuf at feng.bu.edu.eg]

Thanks a million for replying. Your answer helped me. I inspected the errors more closely - with the help of my supervisor - and managed to solve some problems.
Finally the making was successful, by just following steps 1,2 and 3.
I found that one of the problems was that I modify in a wrong Passes.h, as there are 2.
My question now is: How I can apply this pass? (call, use ... etc)
>From what I've read I found that I can't call it from opt.

Dear All

I followed all the steps except the last one, as I don't think my pass depends on anything else, and I didn't fully understand it.
And I tried to rebuild the llvm to make it take my pass into account. I placed my pass in the llvm/lib/CodeGen folder.
But - as I predicted - it didn't work. It stopped here
"make[1]: *** [Transforms/.makeall] Error 2"

I'm not sure if I can help, but looking over the files, I think you're going to have to provide more information on the error.  Is the LLVM build system attempting to compile your files?  If so, what error does it print out (aside from the fact that make is failing; make fails when something fails to compile or link).

Without more information, I doubt anyone will be able to figure out what the problem is.

Attached are my two files

Any help is appreciated.
