The "latest" version of games-emulation/dolphin in the tree is almost two years old, so I'd like to request that the 5.0-rc tag on the github (https://www.github.com/dolphin-emu/dolphin/tree/5.0-rc) be added to the tree. Looking at the tag on github, it seems to be fairly stable (Nothing commited to the tag since July 31), so I'd like to request that we allow an unstable, possibly slotted, version of dolphin for this purpose.
Created attachment 415664 [details, diff] Raw git patch fixing LLVM support Doesn't work with patch without a user specifying the file. This, combined with the miniupnpc patch, will allow a proper build for the 5.0-rc tag or the stable branch (5.0-rc with patches) on github
dolphin-5.0 is now on the portage tree, thank you for submitting this bug report and the patch. Please feel free to submit more bug reports if the dolphin-5.0 ebuild has any issues (which it shouldn't but, you never know).
