Hi,
Since around GCC 10, the condition `j < (INTMAX_MAX / 10)' will get
optimized into `j != 922337203685477580', which will result in an
infinite loop for certain inputs of `j'.
This patch just copies the condition already used by the -DTILEPRO
generator code, which doesn't fall into the same trap.
OK for mainline? OK for backporting to all open release branches?
Sure, but note the tile ports have been deprecated for a long time and
I've got a TODO to finally remove them.
Noted, and I wouldn't mind seeing the back of this port either.
I encountered this as I occasionally I run a modified version of
config-list.mk to test the D front-end. As the target isn't gone yet,
best to ensure it can still build, even when it is assumed broken.
Understood. I've got no objection to you going ahead and installing the
patch if it makes your life easier... Just wanted to make you aware if
you were looking to do something more with that port.
