Hi, I want to try -assume-single-threaded option to measure the overhead of atomic operations for reference counting. However, it seems that the option works as intended with the frontend but not with the driver. In other words, I tried two commands below, and only the first command replaced atomic operations.
swiftc -frontend -emit-sil -assume-single-threaded mytest.swift swiftc -emit-sil -assume-single-threaded mytest.swift Is the option disabled for the driver for some reason? Thanks, Jiho
