[Bug middle-end/78665] Unexpected warning about "assuming signed overflow does not occur when simplifying conditional"
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78665 Martin Sebor changed: What|Removed |Added Status|WAITING |RESOLVED CC||msebor at gcc dot gnu.org Known to work||8.2.0, 9.0 Resolution|--- |FIXED Known to fail||6.4.0, 7.3.0 --- Comment #5 from Martin Sebor --- The warning has disappeared sometime in GCC 8 (GCC 7 still warns). I'm going to resolve this as fixed without going to the trouble of reducing it to a test case.
