Re: [GSoC] How to get started with the isl code generation

By âISL AST generationâ, I mean ISL AST generation without generation
of GIMPLE code.

According to the plan mentioned in my proposal, I wanted to get more
familiar with ISL AST generation by generation of ISL AST in a file,
which is separate from the GCC sources. This could help to avoid
problems with interpretation and verification of results, because I
worked with my own input to ISL AST generator instead of the input
built by Graphite from GIMPLE code. This could also help to avoid
rebuilding of GCC in the process of debugging. However, I've come to
the conclusion that the way you advised me is better, because it helps
to save the time of integration of ISL AST generation in GCC.

I've set up a second code generation in parallel that generates ISL
AST and can be enabled by a command line flag. Could you please advise
me how to verify the results of this generation?

Below is the code of this generation.
