I've now compared the assembler output on i386-pc-solaris2.11 with Sun as and
gas: with as, the g++-dg-lto-20091219-01.ltrans0.s file has a call to
call _ZL20__gthrw_pthread_onceP5_oncePFvvE.2086.2083
but only defines
.weak pthread_once
With gas instead, I have
call _ZL20__gthrw_pthread_onceP5_oncePFvvE.2086.2086
.weakref
_ZL20__gthrw_pthread_onceP5_oncePFvvE.2086.2086,pthread_once
Sun as has no .weakref support.
I'm attaching the assembler outputs both with as and gas.
