Yes, sorry, the list of emutls users grows...
most likely it is my commit from r159781 to address PR44132 that caused this,
1/ Did the same commit improve PR44137 on your target?
(PR44173 looks pretty much the same bug as 44132)
2/ Are you able to try the proposed "proper" solution to that bug (see comment
#24 of PR44132) ?
In the end we will have to address this if lto/whopr are to work with emulated
tls.

I will need some help in tracking down how to solve this (since I don't have an
emutls/visibility/alias target available).
Also I can't find any reference in the gcc manual to alias applied to variables
- only to functions.
(although that might just be documentation lag).
I guess we need to check for the alias attribute in emutls_decl and find our
way back to the original aliased decl. Alternatively it might be enough to
copy the alias attribute onto the emutls control var.

OK, I've built gcc & newlib for cris-elf and it's apparent that we need to deal
with the fact that that aliased emutls symbols are named differently...
that is the user writes alias(foo) ... but the emulated tls system needs to
understand alias(__emutls_v.foo) )
I'll take a look at how to implement this...
.. sorry for this fallout from the other fix
The patch @ comment#24 of PR44132 also needs to understand this issue, and
won't solve this problem yet.

Created an attachment (id=20755)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20755&action=view)
fix up alias output
this fixes it so that we don't try to emit emutls control vars if they are
aliases.
The reference will still be emitted when the original var alias is processed.
This gives no fails on cris-elf (simulator, no pthreads) ..

Sorry I wasn't here to answer the basic simulator-target questions, but it
seems you found the information needed to get you going.

No.

I'll try when the tree builds again (PR44287) if you need it; from your later
questions it seems you've verified this yourself.
Thanks for looking into this!

Yes, the wiki page is good and it all went pretty easily.
One thing you could help with is whether there's a way of enabling threads on
the simulator - and what I need to get to do it.. googling cris pthreads wasn't
illuminating..
I want to keep this target around to test things that I can't do on darwin.

I see pretty much clean* output from check-gcc .... tls.exp=*
* when clean=only fails I expect for non-tls reasons.

Hang fire on that - I've just re-made the "proper" solution to deal with the
aliasing - but I need to re-reg-test on non-alias targets before posting;
if you're interested in trying it, watch PR44132 (but I will use cris-elf as a
test platform anyway).

You mean "for cris-axis-elf"; no, there is no support for threads on
cris-axis-elf.
(I could reply "yes" to your original question, however, but that's irrelevant;
the simulator supports cris-axis-linux-gnu too, but you don't want to build for
that target, it's a slightly more complicated. :)
Let's hope your patch gets reviewed post haste.

If so, and there are no more targets reporting the issue, I will post to
gcc-patches as a proposed fix.

actually, on reflection, I do ...
... I assume that you're saying that building a sysroot is tricky?
... or is there one that's "downloadable" ?
(BTW, this bug should be fixed v. soon)
