This boils down to restrict being implemented as a different alias-set instead
of as points-to information. Dup of PR14187.

Also it should be noted before strict aliasing came about, restrict did nothing
in the compiler.

Yes, and all other bugs should be fixed as well.
This is often impractical. Is there even one large modern
kernel which is compil

Except it is better just to fix your code for aliasing issues. The reason why
restrict does not work without strict aliasing is because it needs aliasing
sets and the only way to get that is with strict aliasing.

[EMAIL PROTECTED] is correct, it's a missed-optimization bug.
(if this isn't a bug, then no missed optimization is a bug)

And this is not a bug, restrict can be ignored by a compiler in terms of
optimization which is what is happening with -fno-strict-aliasing.
