[PATCH] Fix middle-end/16045, fold checksum fails with builtins

Subject: [PATCH] Fix middle-end/16045, fold checksum fails with builtins

The problem here is that we change TREE_NO_WARNING inside fold_builtin which I think is wrong. This fixes the problem by creating a NOP_EXPR for all newly created trees instead of just constants. The only problem I see with this way is we might cause things not to be gimple and reject them.

OK? Bootstrapped and tested on powerpc-darwin with --enable-checking.

Thanks,
Andrew Pinski

ChangeLog:

* builtins.c (fold_builtin): Create a new NOP_EXPR all the time.
