9742	LLVM-5.0	ken@…	Pierre Labastie	"For some reason this doesn't seem to be showing up in the currency check. Announcement at [http://lists.llvm.org/pipermail/llvm-announce/2017-September/000075.html] and downloads are at [http://releases.llvm.org/download.html#5.0.0]

I was going to say ""a word to the wise"", but I think ""a word to the foolish"" might be more appropriate (as in ""trying to build modern software from source is foolish and will cause you pain"") - firefox-56 (due later this month) is trying to move to 'stylo' (new CSS code). That has problems (can't use system nspr or pixman, it can't find the headers ]https://bugzilla.mozilla.org/show_bug.cgi?id=1341234] - comment 10 seems particularly appropriate), but if those are fixed, or else when stylo is no longer optional, clang '''will''' be required for firefox (one of the cargo files needs it).

In circumstances where stylo is enabled, LLVM-4.0.1 is fine - whether or not LLVM-5 will work remains to be determined."	enhancement	closed	normal	8.2	BOOK	SVN	medium	fixed
