[Bug target/113365] LONG DOUBLE: denormals: assigning a constant: factor 100 slow,

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113365 --- Comment #4 from newbie-02 --- hello @Andrew Pinski, just if I'm allowed to add one more point / question: using the testing program, playing with optimization, I get the following results for binary64s ( doubles ): unoptimized:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113365 --- Comment #3 from newbie-02 --- hi, thank you, super service, super fast, works! can't tell if the -O0 behaviour is meaningful ... but think it is rarely used. I came to it in my attempts to avoid compiler cheating / optimizing.
