Phoronix: Wine-Staging 1.7.47 Adds Better GPU Detection, Multi-Threading VCOMP

Building on top of Friday's release of Wine 1.7.47 is a new Wine-Staging release that tacks on a couple extra features...

For those affected by https://bugs.winehq.org/show_bug.cgi?id=38653, GCC has been working on fixing the issues (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66782, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66838)

My Copr builds are currently broken due to GCC issues and I'm waiting for either one of Fedora's Wine maintainers to update the GCC 5 workaround or a new GCC snapshot in Fedora to fix the optimization issues, whichever happens first.

Thanks for these links, I've had some wine issues for a few weeks and didn't look much into it.
That was probably why, so now I know.
Thanks!

Well, the good news is that the recent error that was causing 64bit builds to fail appears to have been fixed in Wine. I suspect that it was only visible with -O0, which has to be enabled with GCC 5 since optimizations break 64bit.

Hopefully GCC fixes all of the 64bit optimizations issues with Wine soon and Fedora updates to a newer GCC snapshot once it does so that the GCC 5 patch can be dropped, enabling optimizations again.

so it sounds like this is a bug in gcc not in wine? if a wine "fix" simply disables optimizations.... so is this actually fixed in gcc yet?

Correct. The temporary workaround for distributions with GCC 5 is to disable optimizations until the bugs are fixed upstream. See post #2 for the bug reports.
