[Bug inline-asm/36639] pointer referenced in asm statement not regarded as VUSE

------- Comment #4 from aoliva at gcc dot gnu dot org  2008-06-26 18:10 -------
I have not tried 4.4.  Anyhow, I have looked further into this issue, and I
came to the conclusion that a memory clobber (that should have always been
there anyway) will get things right.  I cannot tell for sure that it guarantees
GCC will not ever get smart and delete the initializer because it cannot see
that it is used (the ASM needs not be a VUSE if it is marked as using only the
pointer, after all), but I find it unlikely that this will ever break.  So,
nevermind...  Just another case of inlining exposing latent problems.
