Hi Lars, ah, now I get your point which is indeed a point and not a big area :) Maybe the title was misleading because too broad.
You want RISC V support specifically for libobc2 (and clang) where I don't know if it exists or how mature it is. > Am 07.10.2021 um 23:43 schrieb lars.sonchocky-helld...@hamburg.de: > > Hi Nikolaus, > > > I am especially interested in ObjC 2 support, hence I’d like to see > https://github.com/gnustep/libobjc2 being ported (and it needs to, as I > understand it). > > I guess you’re satisfied with GCC’s runtime which you need for your legacy > hardware (Sharp Zaurus and the like).

I haven't as well, it is just the observation that libgnustep-base was obviously successfully compiled for Debian Sid. https://packages.debian.org/sid/riscv64/libobjc4/filelist A quick look into https://github.com/gnustep/libobjc2 seems to indicate that there is a need for a objc_msgSend.riscv.S in parallel to https://github.com/gnustep/libobjc2/blob/master/objc_msgSend.arm.S (ca. 200 lines of assembler code). Everything else is C, C++ or Obj-C code. Best regards, Nikolaus > > > Kind regards, > > Lars > >> Am 07.10.2021 um 22:20 schrieb H.
