BTW, this issue cropped up in Wind River Linux testing, not VxWorks. I have
no idea whether the VxWorks folks are using

Thanks for the input on VxWorks, we'll draft something up about deprecating
this option.
Note that the system compiler uses APCS frames and DWARF2 EH on VxWorks 6,
which is

Uggh - these ancient options in the backend. mapcs-frame is quite ancient
and isn't really something that's tested very often,

While we are here, what's the thought on deprecating mapcs-frame in the
arm-wrs-vxworks community ? It is not really something that's part of the
ABI (it predates EABI),

BTW, this issue cropped up in Wind River Linux testing, not VxWorks. I have no
idea whether the VxWorks folks are using -mapcs-frame. WR Linux will remove
the -mapcs-frame

I talked to the folks who added -mapcs-frame to our builds, and it appears that
we don't actually need it any more. We'll remove it and see what happens.

I can reproduce the wrong-code with gcc-4.9.2 on armv7l-linux-gnueabi. Appears
to need both -foptimize-sibling-calls and -mapcs-frame to trigger.

Re -mapcs-frame: Yes, the failure is due to code in
arm_expand_epilogue_apcs_frame() that explicitly requires / stomps on IP in
order to restore VFP/NEON registers. Sorry, I

Can you add a main() with the necessary parameter setup and call to mark_set()
to make the testcase self-contained and executable? You can annotate
mark_set() with
