Hi GCC developers,
As ChangeLog mentioned:
2017-08-01 Bin Cheng <bin.ch...@arm.com>
* tree.h (POINTER_TYPE_OVERFLOW_UNDEFINED): Delete.
Then how to migrate it for GCC v8.x? for example:
Constant *Result = POINTER_TYPE_OVERFLOW_UNDEFINED ? A : B;
migrated to
Constant *Result = A;
Yes, basically this is what I did in the patch: simply assuming TRUE
and simplifying the expression.
I migrated to GCC v8.x now

thanks for your patch's hint :) it can't work for GCC v8.x, even though
compiled without error, but able to work for GCC v4.6 and v4.8, I am
stuck at rtl_opt_pass https://gcc.gnu.org/ml/gcc/2017-08/msg00045.html
hope I can figure it out the root cause.
Thanks,
bin
because there was a patch 'Make pointer overflow always undefined and remove
the macro' https://patchwork.ozlabs.org/patch/792677/
please give me some hint, thanks a lot!
