Sat Dec 9 16:34:44 PST 2023
https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/74956
This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
