(In reply to Mark Millard from comment #7)

I've tracked down a problem with the armv6/cortex-a7 code generated in
lang/gcc6's xgcc' cc1 and submitted bugzilla 213934 against lang/gcc6 for it.

The history here in bugzilla 213785 is not of much use for the lang/gcc6 issue.
(It might be somewhat useful for the truss crash issue that xgcc's cc1
exposed.)

So I'm closing this report so that lang/gcc6 has a simpler report with just the
actual code generation problem documented.

But bugzilla 213778's report for truss's crashing when watching the failing cc1
is still active and John Baldwin has taken at least one stab at fixing that
issue.

So for now I leave the BPI-M3 environment in the form that allows me to test
truss updates: I'm not exploring compiler option variations and such for
lang/gcc6.
