Confirmed. Btw, the fallback of using hex-style printing for too large
double-ints is bad. Better go via GMP and its sprintf ability.

New Revision: 227964
URL: https://gcc.gnu.org/viewcvs?rev=227964&root=gcc&view=rev
Log:
[PR middle-end/60832] Do not convert widest_int to tree just for printing it.
In do_warn_aggressive_loop_optimizations, we convert to a tree just to print a
widest_int. Apart from overly complicated, this results in printing '3u'
instead of just '3'.
Unfortunately, adding a printf-like conversion specifier would require making
pretty-print.c link with wide-int.cc, which will include a lot of new
dependencies into several other programs (gcov-tool for example). It would be
possible to add the conversion specifier to every FE pretty-printer, but this
still would require updating c-format.c, which is far from trivial. A simpler
approach is to convert to a string rather than to a tree.
In addition, "iteration 3 invokes undefined behavior within this loop" seems to
me clearer than "iteration 3 invokes undefined behavior; containing loop".

pretty-print.c is used all over the place and adding a dependency on
wide-int.cc will bring gmp and other stuff that is currently not used (nor
linked with) various helper programs. If wide-int is only printed in the
middle-end, perhaps it is sufficient to add it to default_tree_printer.
Otherwise, it needs to be added to every FE. This is not difficult just
tedious. The difficult part is the c-format.c changes (I wish someone would fix
https://gcc.gnu.org/PR47781 so we can use a simpler syntax to define our custom
specifiers; in addition to the positive synergies it will bring with other GNU
projects that use custom specifiers and wish to use -Wformat).

Probably. Will look at this today (valgrind has some sort of memory pool API, I
think it can be used here).
I need to configure GCC with --enable-checking=yes,valgrind to reproduce this,
right?
