Error extracting polyhedra in Pluto

[Hrishikesh Vaidya]

Hi,

    I am facing a problem while using pluto for optimizing my code. It gives an error message and I am unable to figure out the reason. I am attaching the section of code "sample.cpp" which is giving error when passing through pluto. The error message generated is:

[Clan] Error: syntax error at line 8, column 15.

Error extracting polyhedra from source file: 'sample.cpp'

The version of pluto being used is :

PLUTO 0.11.4-54-ga372de9 - An automatic parallelizer and locality optimizer

clan is unable to extract min(max(k * 1 + i * 2, 0), 7) and min(max(l *
1 + j * 2, 0), 7) as piece-wise affine functions of i, j, k, l (note
that these expressions aren't affine in i, j, k, l). This code works
when the pet frontend is used with Pluto (--pet). Additional support may
have to be built into Clan to recognize these.

Thanks,
