Subject: [PATCH] libstdc++: Optimize operator+(string/char*, string/char*) equally
Date: Mon, 22 Aug 2022 14:15:08 -0400	[thread overview]
Message-ID: <> (raw)

After consultation with Jonathan, we realized that there was a missed
optimization opportunity in the implementation of the various forms of
operator+ for string.

operator+(char *, string) required a single allocation but 
operator+(string, char*) required two. This patch attempts to change that

Again, I have been a longtime reader of the source code but this patch is one of
my first attempts at contributing. I have attempted to follow all the rules but
I am sure that I missed something. Please let me know if/how I can change the
patch to make it acceptable.

Thanks for all your hard work maintaing this vital piece of software!
