Hello, the SH backend in GCC is currently in rather poor shape and could need some overhaul and for that matter, I'm looking for an experienced GCC developer who might be willing to fix some bugs in the backend for money.
I have started similar efforts in the past for the avr, m68k and vax backends, back then using the platform Bountysource in order to convert those backends from cc0 to MODE_CC with great success. All of these backends could be saved from being removed from GCC due to this work. Unfortunately, Bountysource went bankrupt, so we can't just put up bounties there again to work on GCC. However, there are plenty alternatives such as OpenCollective, Patreon and Algora.io and probably more. There is also a larger homebrew community around the SuperH architecture, mainly due to the Sega Dreamcast console. Popular projects are the KallistiOS [1] and various game ports to the Dreamcast such as GTA3, Counterstrike and many more [2]. Chances are therefore not bad that we would be able to collect some funds to motivate an experienced GCC developer to work on the SH backend. There is already an ongoing discussion in one of the Dreamcast forums on this topic and several people already said they'd be willing to support the effort [3]. Thus, I'm wondering now whether there is any GCC developer out there who would be willing to fix some of the bugs in the SH backend for money. There are currently 194 bugs that can be associated with the SH backend [4]. While I don't expect it to be realistic to get all of these bugs fixed, the most important bug to be fixed would be PR55212 [5] which concerns switching the backend to the new register allocator LRA. We'd already moved a huge step forward if the backend could be switched to LRA as one of the most common failures that we're seeing downstream in distributions are register allocation failures such as the one reported in PR81426 [6]. Would there be anyone willing to work on switching the SH backend to LRA while being paid for it? And what would be their payment platform of choice?
