<richi> hmm, is libtsan not multi-libbed?
<jakub> richi: it only works on x86_64 right now
<richi> ugh
<jakub> richi: so, it is multilibbed, but only built on multilibs and
targets which are supported
<jakub> richi: as it often needs lots of RAM, it is probably not going to
be supported on 32-bit targets at all
<jakub> richi: no reason not to support it on say ppc64 or sparc64 or s390x
I guess, just needs work
<richi> jakub: where is asan supported? everywhere?
<jakub> richi: but then, I haven't even read what exactly libtsan does,
only looked at the atomics in there, and did the GCC side from what I
knew should be instrumented
<jakub> richi: asan is right now supported on x86_64/i686, ppc/ppc64,
perhaps partially x86 darwin (don't care) and in theory arm (nobody
tested)
<jakub> richi: porting isn't that hard, but the library isn't as clean as
it would be desirable portability wise
<jakub> richi: that said, I don't want to spend as much time as I've done
so far on it, and in the time I'll allocate for it optimizing the code it
generates is higher on the todo list than ports to other targets
