gcc-12+: D / phobos runtime

2023-09-03 Thread ASSI 


Starting with gcc-12, gcd needs a D compiler to bootstrap, but gcc-11
does not allow to build the necessary runtime on all platforms (Cygwin
for instance).  How is the prospective bootstrap sequence on such
platforms?


Regards,
Achim.

The value of .CLZ (0) is undefined then.  I belive your analysis is correct in
that both 63 - _35 might overflow and that dom3 (thus ranger) mis-computes
the range for _35.  I wonder why we don't elide _36 ? _31 : 1 with that info
(possibly no range-op for .CLZ?), of course it would be wrong to do so.

Can you open a bugreport please?
