From 72127b193c970a61a36c940bf167c596ddc32eae Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Thu, 20 Oct 2022 12:48:27 -0400 Subject: gdbsupport: move fast_hash to gdbsupport/common-utils.h The following patch adds a hash type for gdb::string_view in gdbsupport, which will use the fast_hash function. Move the latter to gdbsupport.
