More Details On The AMD GCN Back-End For GCC That's Expected To Merge For GCC 9

In Summary :

Last week I reported on Code Sourcery / Mentor Graphics posting their new AMD GCN port to the GNU Compiler Collection (GCC). This GPU back-end for the widely-used GCC compiler is hoped for merging ahead of the GCC 9 stable release expected in early 2019. At this past weekend's GNU Tools Cauldron 2018 conference was a briefing by Mentor Graphics on undertaking funded by AMD.

Andrew Stubbs who posted those latest AMD GCN patches last week for GCC was in attendance at the Cauldron in Manchester (UK) to talk about their AMD GPU back-end work for the GNU compiler toolchain. Among the highlights are:

- AMD has indeed been funding Mentor Graphics to create this new GCC port... It was pretty much assumed, but not entirely clear with AMD and SUSE being long-time partners and SUSE having originally started working on the GCN back-end in 2016. But it turns out AMD ended up hiring Mentor to work on this code since 2017 while using the SUSE code as a starting point.

- One of the explicit requirements by AMD is for this GCN back-end to handle Fortran code (GFortran) with the OpenACC and OpenMP parallel programming interfaces. [...]
