https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82888 --- Comment #3 from Nathan Froyd --- Thanks, I didn't think to test -O3. Do we get the memset at -O3 because loop idiom recognition is enabled? Producing the memset upfront probably generates better code for all cases, even if the frontend

[Bug c++/82888] terrible code generation for initialization of POD array members vs. clang

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82888 --- Comment #4 from Marc Glisse --- The front-end internally uses VEC_INIT_EXPR, and gimplifies it to a loop. I believe we should end up with an empty CONSTRUCTOR instead.
