pollycc reports syntax errors due to local variables about pluto

[bondhugula]

The Clan frontend can't parse the declaration inside. You can use the Pet frontend (--pet) to deal with it. However, you'll run into another issue with the accesses (i*n_a_rows+k and others will be seen as non-affine ones) since there's no dimension lifting / delinearization support. So you'll have to use 2-d arrays if you want the dependence analysis here to work (i.e., m[i][j] += a[i][k]*b[k][j]).

$ polycc --pet --tile --parallel matmul.c -o matmul
/stuff/pluto/src/pluto: unrecognized option '--pet'

[bondhugula]

The --pet option is only available in the 'pet' branch of the git. (You'll also need LLVM/Clang 3.4 for this). In any case, if it's rewritten in a way such that those accesses become affine, you'll be able to run it even without --pet.

Then why are things like this in the master branch?

Thanks for reporting - fixed.

There are a couple more of those: https://github.com/bondhugula/pluto/search?utf8=%E2%9C%93&q=--pet&type=

Including benchmarks that needed --pet in the master branch was an oversight as well. Dropped now. Thanks.
