Please make sure you look at the right variant, i.e.
"sysdeps/i386/bits/string.h", as there are different versions for different
i386 submodels. Still the version in the glibc tree differs a bit indeed,
but i

Yes, the funny cast is *intended* to alias all memory, and thus force anything
that might potentially alias the string to be written back. We don't have the
ability to conclude that __d3 won't be affected.

Thanks for your insight. I did some experimenting with the code (including
reducing the source file to a somewhat more readable form -- I can post it
if interested) and I noticed this *(struct { char __x[0xff

I'm calling this one invalid. We've got:

Amusingly, the problem disappears when one translates this:
salt_len = (((strcspn (salt, "$"))<(8))?(strcspn (salt, "$")):(8));
to
salt_len = strcspn (salt, "$");
if (salt_len > 8)
salt_len = 8;

I'm sorry, this is Andrew's fault -- it's not a duplicate.

Of course not! Have you forgotten what early-clobber means?

Richard,
Thanks for your work (for bug 21291). Unfortunately it's not enough for
this case. It doesn't seem to work for the "g" constraint used there, but
that might probably be considered just a shortcomin

If I understand this correctly, older GCCs were able to
figure out that when there is 5 registers available,
"=&g" (__d3) can olny be matched with memory (on-stack local var)

What I mean is this is a known non-bug in GCC in that running out registers
cause things to wrong with
people's inline-asm on x86. If peop
