https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67442 --- Comment #5 from Richard Biener --- I wonder how many bugs of this kind we have lurking in the tree... It works fine when type has the same signedness as pcst of course, but as we don't know pcst sign we can't check for that case... The only

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67442 --- Comment #6 from Richard Biener --- Ok, truncation also should work, thus gcc_assert (prec <= pcst.get_precision ()); (trying to see how far bootstrap goes with that)
