Hi all, I've submitted my proposal to the GSoC website, it can be found here: [1] After hearing some ideas from Oleg, I decided to go with working on detecting and optimizing a few specific memory access patterns instead of implementing a PBQP solver. Any suggestions or comments are welcome. I rea

[gsoc] Generic addressing mode selection

2015-03-22 Thread Erik Varga
Hi all, I'm Erik KrisztiƔn Varga, a 2nd year Electrical Engineering student, and I'd be interested in contributing to gcc as part of GSoC 2015. I'd like to work on adding an addressing mode selection pass to the RTL based on the ideas described in Eckstein et. al.'s paper on the subject [1]. The b
