So it turns out this is kinda of a latent bug but not really latent.
In GCC 9 and 10, phi-opt would transform a?-1:0 (even for signed 1-bit integer)
to -(type)a but the type is an one bit integer which means the negation is
undefined. GCC 11 fixed the problem by checking for
This one looks OK. Sorry I missed it earlier. Thanks again for the patch!

Re-sent with gzipped attachment as gcc-patches@ did reject it as being too
large.
Alternatively, you can find it at

as fortran@ contrary to gcc-patches@ did accept the patch ...

Thanks for the quick review!

We seem to be passing a lot of context around in the strlen code. I
certainly don't want to contribute to more.
Most of the handle_* functions are passing the gsi as well as either
ptr_qry or rvals. That looks a bit messy. May I suggest putting all
of that in the strlen pass object (well, the
When determining the size of an object compute_objsize_r() assumes
that addresses derived from null pointers are not derefernceable
because null pointers themselves are not, without calling

Hi,
This patch fixes the typos introduced by commit r12-4240.
The dg-warning format looks like:
{ dg-warning regexp [comment [{ target/xfail selector } [line] ]] }
Some dg-warnings such as:
{ dg-warning "\\\[-Wstringop-overflow" { target { i?86-*-* x86_64-*-* } } }
miss the comment field, it
