"I've been writing C for quite some time, but I never followed good conventions I'm afraid, and I never payed much attention to the optimization tricks of the higher C programmers. Sure, I use const when I can, I use the pointer methods for manual string copying, I even use register for all the good that does with modern compilers, but now, I'm trying to write a C-string handling library for personal use, but I need speed, and I really don't want to use inline ASM. So, I am wondering, what would other Soylenters do to write efficient, pure, standards-compliant C?"

You mean whenever I change a string in Java, the JVM runs through ALL my strings in memory to make sure I don't have a duplicate string already? and there's no opting out??
Yikes, that sounds like a huge waste of CPU cycles. I'll happily trade memory to get that performance back, thanks.

It's done with hashes.
